This article shows you how to re-flash the firmware on the Thomson 585v7 and 585v8. You may want to do this if you're running an old version of the firmware, you suspect the firmware on your device has become corrupted or if you are having problems using a PPTP-based VPN solution. * A firmware update can also fix certain wi-fi connectivity problems affecting older revisions of the 585v8. **
* The PPTP ALG is not present in the 585v7 v184.108.40.206 firmware that shipped between November 2009 and May 2010. If you're using this firmware build then there's a possibility that you will not be able to connect to PPTP-based VPN solutions (quite commonly provided by Microsoft). To fix this problem we recommend you upgrade to v220.127.116.11 which *does* support the PPTP ALG.
** The 585v8 v18.104.22.168 firmware is known to cause wi-fi connectivity problems with certain Apple computers. To fix this problem we recommend that you upgrade to v22.214.171.124 that features updated wi-fi drivers from the chipset manufacturer. No official upgrade tool exists for Apple computers so you may need to reflash the firmware using a Windows computer instead.
Things to consider
Thomson 585v7/585v8 firmware flashing utility ~ Windows 7 users, use the version here instead.
Windows 8 users - sorry no update tool is currently available for this operating system.
However some users report the Windows 7 version works in Windows 7 compatibility mode.
Note: These update tools can also be used to update the firmware on the TG582n. However the firmware mentioned below is NOT for that router - see here for TG582n firmware.
585v7 version 126.96.36.199 firmware (Plusnet branded) ~ PPTP ALG enabled / WPS disabled / *not* patched against XSS vulnerability
585v7 version 188.8.131.52 firmware (Plusnet branded) ~ PPTP ALG disabled / WPS enabled / patched against XSS vulnerability
585v7 version 184.108.40.206 firmware (Plusnet branded) ~ PPTP enabled / WPS disabled / patched against XSS vulnerability
585v7 version 220.127.116.11 release notes
585v8 version 18.104.22.168 firmware (Plusnet branded) ~ PPTP enabled / WPS disabled / patched against XSS vulnerability
585v8 version 22.214.171.124 firmware (Plusnet branded) ~ PPTP enabled / WPS disabled / patched against XSS vulnerability / updated wi-fi drivers
Before you start
Download a copy of the flashing utility and unpack it to a location on your hard drive. You'll also need to download a copy of the firmware you're wanting to upgrade/downgrade to.
Establish which router model you have
If your router was dispatched after 18th October 2010 then you are likely to have a 585v8. If your router was dispatched prior to this then you're likely to have a 585v7. There are some discernible differences between the two units making it pretty simple to establish which model you have.
You could check the model number on the base of the router:
There are also aesthetic and design differences between the two units. The 585v8 has no ethernet LED's on the back, the power switch has been realigned to make it more accessible, and there are air vents down the side of the unit:
The Thomson firmware builds linked at the top of this article are not cross-device compatible i.e. 585v7 firmware will *not* work on a 585v8 device and vice versa.
Checking your firmware version
You can check the version of the firmware you're using by browsing to http://192.168.1.254 (you may need to enter the router administration username and password; if you don't know what these are see the TG585 FAQs page here).

I've corrected the link to that in the article.
Ive just done this on my router and now the interface is very very sluggish.Also my gaming consoles that ive hooked up,xbox 360 and a wii console dont seem to be remembered now unless they are online then they are viewable in the interface and when off line they are not there?
Might be worth flushing your browser cache to see if it improves the responsiveness. I'm not using a 585v7 at the moment so I can't comment on the latter of the points you raise - does it cause you problems?
No it's not causing problems,all is working well just thought id say what's happened,overall great instructions and worked for me.
So what does V8 of the firmware offer? What bugs has it fixed and does it offer any really good new features?
The main change was to patch a known XSS vulnerability. At the same time the PPTP ALG was removed meaning you can't use PPTP-based VPN solutions with the v8 firmware. I believe the v8 firmware also supports WPS as long as your wireless client does. RTM to see what WPS is - http://www.thomsontelecompartner.com/getfile.php?id=5117
Worked a treat here on win7 (the link for the win 7 didnt work)
However when clicking setup, the compatability window pops up, select the first option and it ran a treat.
Didnt save the configuration properly tho, using a different IP (which it lost), also it didnt save the login details correctly, and went to expect the auto system to set it up (turned off)
Also hasnt saved my port forwards ... so what did it save? heh..
V8 interface seems to be much smoother imo, seems to lag only rarely.
The Windows 7 link should be fixed now Matt
Just followed all the instructions to the letter now I have a router that doesn't connect properly and web addresses do not resolve. Luckily I had my old NetGear router to replace it with.
does a hard reset help codenumpty? (i.e. sticking a pin into the hole at the back of the unit until the lights go off/on)
I am trying to connect to my employer's network using VPN, which requires the PPTP protocol.
I installed firmware version 7 as above (release 126.96.36.199) but the connection keeps failing with error 721. My Windows firewall is
I independently inquired with Thomson. They sent me a doc "open ports/port forwarding". Do I need this?
[ follow up to previous message ]
I meant to say that my Windows firewall was ON.
The error persists when the firewall is OFF (the error code is 721 or 619).
@avramidis, we've got an updated version of the v8 firmware now with the PPTP ALG re-enabled. You could try flashing with that to see if it helps. I'm going to update this article to include a link to the new build (v188.8.131.52), in the meantime though you'll find a copy here -
I've updated the article now to include download links to the new firmware builds.
Bob, it is now working! Thanks!
Glad to hear it!
I also lost my internet connection after downgrading from 184.108.40.206 > 220.127.116.11, according to the internet connectivity test everything was working except for the internet.
I found by having some patience and waiting ~5 minutes for a website to load that I was being forwarded to somewhere on the plus.net website to complete setup, and after entering my username and password everything started working again. However this setup page was very slow to load and actually failed with "webpage not available" most times, hence the long wait to realize there was an attempt at redirection.
Sounds like the firmware reflash reset your dsl login details to connect to our TR069 platform. If you'd checked and re-entered these then there would have been no need for the redirect to the Plusnet website.
Normally the router will configure itself automatically when this happens but that's dependent on it being scanned by the warehouse when it was originally dispatched (which I'm guessing yours wasn't).
Is 18.104.22.168 newer than 22.214.171.124? The numbering indicates it might be, but hard to tell with thomson
I'm on 126.96.36.199, but it's flaky like hell. By that, I mean that if I have plug and play enabled, and wireless, the router will do a warm reboot for no reason at all. Even adding a static DNS entry on the devices menu can cause the router to reboot.
-- gyre --
Hi Gyre, 188.8.131.52 is the newest version although I understand the confusion!
I'll let our hardware guys know about the problems you're having.. has this only occurred with 184.108.40.206?
Have any of you people managed to Flash with the Unbranded firmware. I get about 2/3 of the way through the firmware install and it gives up.
I need to be able to set things like the ability to access the router from the Internet using the DynDNS service and in the branded firmware I am unable to get to the config options I need
I had a problem connecting via my Cisco VNC to my work microsoft outlook server account. The PlusNet Technical helpdesk told me to upgrade the firmware to 220.127.116.11 which i have done but the problem still exists in that although i can connect to the VNC , it will not pull down any messageson my email server.
The VNC has worked on every other wireless router i have tried. HELP!!!!
You might want to give version 7 a go if you haven't already Stuart? Also, have you tried a factory reset?
@john, not aware of any probs however i guess the file could be corrupted? I'm not in a position to try it at the mo. TBH I thought the web interface was identical navigation-wise, perhaps what you're trying to do needs to be done using the CLI?
Yep, i have gone back to v7 and done a factory reset and neither v7 or v8 work. I am now back on 18.104.22.168 and havene't gone back up to v8. Any ideas????
Sorry Bob, just to clarify i am talking about VPN problems and not VNC!
Stuart, bit miffed then TBH - do you know whether or not the Cisco VPN is reliant on PPTP as I'd expect it to be IPSec based or similar?
When you say you can't pull down emails, what client are you using and what happens when you try?
Am I right in assuming that you can swap in a non-Thomson router and everything works fine?
I tried a Siemens modem over the weekend and that didn't work either!
I will check with work re PPTP and IPSEC, and will coem back to you.
Stuart, I've just had a thought. You haven't got our server-side firewall switched on have you? - https://portal.plus.net/my.html?action=firewall
The Cisco VPN uses ipsec i am reliably informed.
I have tried the modem in both (firewall) enabled and disabled mode.
Still no joy????
My IT guys have asked me to ask you to confirm that the Plusnet network accepts VPN. I'm sure the answer is in the positive otherwise you would have told me already, but please confirm.
It was the firewall on our website you disabled and not the one on the router/your computer wasn't it?
Yes, our network does support VPN. I use it to connect to our Cisco based implementation at work.
I've tried flashing the 585 with all versions on this page in an attempt to enable PPTP
v7 wouldn't let me online and locked me out of my router even when I used the defualt v7 username/pw
22.214.171.124 unbranded sent me to a BT login page instead of the PNET one so I cannot confirm if this works
126.96.36.199 branded worked fine but again couldn't connect to VPN
I called up PNET and the chap said they have a new router which supports PPTP. I received it today and it's exactly the same as the one I had before with the 188.8.131.52 FW which also won't let me connect. (Was I charged for that BTW?)
So I'm wondering is there anything left to try?
OK i set the firewall through your link to OFF and disabled the firewall on the modem too.
I have done this on both v7 and v8 and still no joy!!!!
Any other hints, advice etc???
@stuboo, i'm running out of ideas TBH. The fact that you couldn't get things working with the Siemens modem either doesn't bide too well.
You mention that you can connect to the VPN itself but just can't pull emails down? I'm beginning to think that it might be your IT bods who are going to be best off diagnosing the problem from here onwards although I'm happy to answer any questions about our service that they might have.
Do you have a laptop or a desktop? If it's a laptop have you been round to a friend/family members house to see if you can get the mail account working over the VPN from their connection?
@oscar18, what account type are you on and have you tried disabling our server-side firewall? - https://portal.plus.net/my.html?action=firewall
Not sure what you mean by account type Bob, I'm on Plusnet Value if that helps.
Yes my firewall is off.
@oscar18, i asked because VPN is rate limited on the Value package - http://www.plus.net/support/broadband/speed_guide/download_speeds.shtml#valueSpeeds
Having said that it shouldn't outright prevent you from being able to connect. I'd be interested to know how you get on with a non-Thomson router. Are you able to source one from anywhere?
@andrew b, the flakiness is on both 184.108.40.206 and the latest firmware. I have 2 plusnet branded 585v7s and they have similar amounts of flakiness.
However... putting the router into bridge mode and turning off wireless, they seem to be rock solid. So, I'm doing that for now
Bob Pullen, you are a star, VPN up and running. Thank you!
@Bloz, you don't *have* to upgrade but if you don't I'd suggest you change the default username/password for the router interface - http://community.plus.net/library/browsing/changing-the-default-password-on-a-thomson-585v7/
If you do decide to upgrade then go with the Version 220.127.116.11 build
Bob, great article. I'm using the 1-port wired ST516v6 (BANT-V). Would you be able to post the update tool and latest Plusnet firmware for that, and possibly lay your hands on firmware 7.447 or newer? I don't really mind whether it's Plusnet or Thompson branded but I suspect that the version 7.447 that I found elsewhere is not really the latest available for those in the know. Thanks in advance!
Hi Ben, AFAIK the latest version *is* 18.104.22.168. You can download a branded version here - http://www.binarybob.plus.com/thomson/firmware/516v6_branded_22.214.171.124.bin
The firmware upgrade tool linked in the article should work for the 516v6 too.
Hi Bob, many thanks for your rapid response and for posting the firmware. My current ST516v6 (received earlier this month) has Plusnet-branded firmware version 126.96.36.199, though I am led to believe from comments on other forums that this rather large jump actually reflects only a minor customisation, and that 188.8.131.52 is indeed the latest officially supported version as you mention. Have you heard of 184.108.40.206 and can you comment on what the modifications are versus 220.127.116.11? At any rate it seems I don't need to update my router after all if I already have the latest available firmware, although it's good to have 18.104.22.168 from a reputable source as a backup. Thanks again!
Hi Ben, no I wasn't aware of the v22.214.171.124 build but I must admit I don't follow the 585v6 as closely. I'll give Thomson a shout and get back to you...
@maccoylton, have you tried using the Windows 7 version?
Is there a firmware flashing utility that can run on OS X?
Alternatively, can I push the bin file to the device over SSH or telnet and have it flash from the command line?
I can't speak for it's validity/success rate (as AFAIK Thomson have not released an official version), but there's a MAC flashing utility on Be Broadband's website here - http://beusergroup.co.uk/technotes/index.php/Modem_Firmware#Mac
If you try using that though, you'd be doing so at your own risk.
You /can/ use bootp/tFTP to flash the device as well. There's a guide at the aforementioned URL, however it does contain references that are specific to Be's firmware builds/routers.
If you do fancy writing a Plusnet-specific guide then feel free. Anyone is welcome to write support articles on this website.
The links to the firmware builds do not work?
Hmm,it looks like that server might be down.
nope, i (unintentionally) broke the links with an .htaccess file (doh!) - should be sorted now.
I saw you were helping people sort firmware updates, I spoke to someone on the phone at plusnet and requested an update but it hasn't been done. can you ask for my firmware to be update please as im on a mac I can't do it myself, is that still the case?
Hi Barry, the guys who normally looks after remote firmware upgrades is on leave at the moment and isn't scheduled to get back until the 18th Janaury.
In the interim, it might be an idea to see if you can use a friends/family member's Windows machine to do the upgrade.
There are ways of upgrading the firmware on a MAC (see my reply a few posts up), but I wouldn't recommend trying unless you're reasonably technically minded.
I need to have vpn so I can access uni related stuff, I've been told I need to ' downgrade the firmware on the router back to version 7'. I've no idea how to do this so any help would be much appreciated!
Clare, the article at the top of the page should help you with this? What in particular are you struggling with?
FYI. I was experiencing wifi connectivity problems using a Win Phone 7 mobile. Upgrading to firmware version 126.96.36.199 resolved this for me.
I've read the info at the top of the page, but still can't seem to do it! I connect the laptop with the ethernet rather than wireless and get as far as stage 5, but then it can't find the Thomson Gateway.
Thanks for helping me! Clare
Upgraded the fimware,but its made no difference to poor upload speed, see post here http://is.gd/dDccWm
@Clare, if you connect the laptop via Ethernet, can you browse to the router interface at http://192.168.1.254 ?
If you can't, then the problem is to do with the ethernet link between your laptop and the router. Trying another ethernet cable, or manually configuring the TCP/IP properties of your network card would be the next steps I'd take.
Hi I've upgraded my 585 v7 to the 188.8.131.52. firmware but can cannot access the routers web page I've tried Administrator for user name with password left blank but thease are not accepted.I've reset the router but still no look.
Yes, the admin username and password for that version of the software is different. This is explained in the paragraph just below the last image in the document. The username you need is admin and the password will be the serial number of the router CP.... with all letters upper case.
Many thanks spraxyt I have now sorted this out,the confusion was understanding that I've got version 8 firmware on v7 hardware.
I agree there was scope for confusing v8 firmware and v8 routers. I've updated that paragraph in the article to make this clearer.
Hello! Is there a firmware which offers the possibility to log how much traffic is being made by each connected device?
@adi2004, not to my knowledge there isn't I'm afraid.
If the devices are Windows PCs installing NetWorx on each PC might provide the breakdown you are seeking. Setting options include exclusion of local traffic, defining peak hours and a "master" PC can be set up to amalgamate individual PC usage.
I have an issue. I have just upgraded my tg585v7 from v184.108.40.206 to v220.127.116.11 and the router is asking for the Administrator password. It isn't what the password was before the upgrade, it isn't a blank field as mentioned above nor is it the serial number (as mentioned in the original documents). I'm a bit stuck now as I would like to be able to check how quick the router is connecting.
It should be 'admin' as the username (case sensitive minus the quotes), and the serial number as the password (case sensitive again but minus the bracketed numbers at the end).
Thanks. That works. Panic over.
The IPASS vpn client that my work windows based laptop uses is giving me a 'failed to acquire network address' error message with my current firmware of v18.104.22.168 but shouldn't this version be compatible for VPN since it's later than the 22.214.171.124 recommended above? Any idea what might be causing the issue?
@McBee, the PPTP problems should only affect the v7 units. Judging from the firmware revision you're using you have a v8 unit? Is iPass a PPTP solution? (I'm not familiar with it). Neither am I aware with any VPN specific problems with the v8 devices I'm afraid
Further to your recommendation when I reported connection issues with the new router you sent me, I managed to find my way through this upgrade process. However it couldn't complete the upgrade, no matter how many times I tried. What do I do now..?
@SarahC exactly what problems are you having, and do you know what firmware revision you're running at the moment? (the article above tells you where to obtain this information)
I thought I would check my routers version of the firmware but I have not got past the router administration username and password. I have not a clue what they are or where to find them. Assistance in simply terms for a near complete computer novice would be appreciated.
Details of the username and password for accessing the TG585 web interface can be found in the help page here.
I've added this information to the article too.
Brilliant article and very helpful. I bought a £3 585v7 router off ebay as a spare (just in case) but it was programmed to work only with TalkTalk.
I followed the instructions on here and now it is working on Plusnet with 126.96.36.199 firmware. Only point to watch is that some devices apparently have Administrator as a username, some have admin. admin (all lower case) worked for me after the firmware upgrade. The password is the CP number (S/N) on the base of the router - note all upper case letters in this. Then just tell it your plusnet user name and password and it connects to internet in no time.
Thank you to the authors of this support article!!
If you copy the new version of firmware to the Builds directory before you start the flashing utility it finds it immediately and misses out all the steps 6 and 7 to do with browsing to the firmware to upload.
is there any upgrade software that works over windows 8....?
Have tried the windows 7 but does not install saying not for the system.
I don't recall seeing a Windows 8 compatible tool being mentioned.
Probably need to ask Plusnet to upgrade the software remotely.
No there isn't a Windows 8 compatible firmware flashing application as yet. I don't think Technicolor have one in the immediate pipeline either. As spraxyt's mentioned it might be worth asking support whether or not it can be done remotely.
According to the Community post here the Windows 7 update tool works on Windows 8 in Windows 7 compatibility mode.
I thought there was already comment here that the Tools also support the Upgrading of the TG582n firmware as well. As there wasn't, I thought I'd add the comment as I know a few users have been confused.
Thanks. I've added a note to the article mentioning the tools can be used on the TG582n and provided a link to the firmware for that router.
I did ask about compatibility mode but our office guru advised me it still didn't work. Thanks for the clarification.
Is there any chance we can get the parental controls and website blocking features enabled on the tg585 v7?
@Minxymoo, it's very unlikely considering the fact that neither Technicolor or us are shipping the device any more. Even if it is possible, creating new firmware builds is quite an arduous task due to all the testing etc. that's required. If you were to contact our helpdesk then they may be able to arrange for a replacement 585v8 to be sent out.
