582n router trial initial thoughts

brueton — Fri, 23 Dec 2011 11:59:34 GMT

Works out of the box with IPv6 on an ADSL connection
Using it to post this. Getting 10/10 on test-ipv6.com, with both Windows 7, fedora 16 & Android.

-edit again! - rebooted and now score 9/10.

Your DNS server (possibly run by your ISP) appears to have no access to the IPv6 Internet, or is not configured to use it. This may in the future restrict your ability to reach IPv6-only sites.

I'm scoring 0/10 on that test.

Validates that IPv6 requests with large packets work. If this test times out, but other IPv6 tests work, it suggests that there may be PMTUD issues; possibly involving IP tunnels.

(This is bonus credit)
This is a test of your ISP's resolver (instead of a test of your host). If this test passes, your DNS server (often run by your ISP) is capable of reaching IPV6-only DNS authoritative servers on the Internet. This is not critical (at this time) for you to reach sites via IPv6.

The over-view for Internet Services / Internet Connection seems like it has a mis-reporting error:

Quote
TCP/IPv6 Settings
IPv6 State: Enabled
IPv6 Address: fe80::a76:ffff:feb5:67be/64
DNS Server 1: 2001:470:20::2

I believe the fe80 is a 127.0.0.1 type IP address, so it isn't showing my IPV6 address.
Service configuration is an area that needs work too. From what I can see the only way to make alterations is by going through the Wizard which means starting from scratch, I put in the wrong password so had to go through the wizard again to put in the correct one, though it's probably something that people are only ever going to use once but it would be nice to have the option of being able to manually change just 1 setting.
Speed wise, my Attenuation went from 34 to 33, so it's lower than on my Cisco, if the SNR drops to 3 it'll be even faster!
I'm having issues, just tried to run http://ipv6-test.com/ and "Your internet connection is not IPv6 capable" which is odd....

Are you getting 10/10 on Android? What browser, and OS version, are you using?
It's good if you are - picking up IPv6 DNS settings on Android has been an issue for a long time but if that's been sorted in more recent updates (I've got Android 2.3.5) that's a great sign.

Re: 582n router trial initial thoughts

Okay thanks Pete. Perhaps it's picking them up out of the RA advertisements from the router (rather than DHCPv6 which I'm having to use for DNS as my Cisco doesn't seem to pass the DNS server details on).

@David W
"Listen to IPv6 RA..." should be un-ticked as per the setup instructions, did you mess that step out?

Re: 582n router trial initial thoughts

David_W — Fri, 23 Dec 2011 12:42:34 GMT

Nope, followed the instructions in the PM as I was setting it up, it's all working now after a reboot, except the DNS servers report on test-ipv6
-edit- still having the issue with IPV4 speeds being capped at 7Mb too so it rules out a router issue.

Re: 582n router trial initial thoughts

brueton — Fri, 23 Dec 2011 12:47:20 GMT

I was getting 9/10 on my 7800N for some OSs.
Think it was due to the OS (Linux & Android) using the IPv4 address of the router for DNS and not picking up the IPv6 DNS from the router.
Windows 7 & Vista would report 10/10.
Never spent enough time to get to the bottom of it.

Two for two with a single reboot then, looking good for the Technicolor so far

Re: 582n router trial initial thoughts

David_W — Fri, 23 Dec 2011 13:25:39 GMT

I'm scoring 10/10 now on IPV6 so I'm guessing it's the website itself that's incorrect at times

Re: 582n router trial initial thoughts

MJN — Fri, 23 Dec 2011 14:08:01 GMT

That's probably unlikely as detecting what transport the DNS query is coming from is fairly easy.
For those clients that do get an IPv6 entry in their resolver list the issue is more likely the fact that will also have IPv4 entries in there and might not always be preferring using the former over the latter. In most cases it will actually be that no IPv6 entries whatsoever are getting into the resolver list due to varying degrees of support for RA and DHCPv6 in both routers and clients alike.

Re: 582n router trial initial thoughts

David_W — Fri, 23 Dec 2011 14:14:53 GMT

But using same browser, same router, same OS, same everything and getting two different results from the same website should be more an indicator of a problem with the website shouldn't it?

Re: 582n router trial initial thoughts

MJN — Fri, 23 Dec 2011 15:09:04 GMT

Not when the resolver list contains a mix of IPv4 and IPv6 resolvers to use. Whilst most OS's try each resolv in order (that they appear in the file) some also attempt to optimise future lookups by noting which resolvers are responding quickest. It can only take a temporary networking issue to cause a timeout and for that resolver to be missed on that, and possibly future, lookups.
Of course, I am not in a position to categorically state that the website couldn't make a mistake - however given that the resolver list behaviour is known, and can lead to different results from one query to the next, I'd put my money on it being a client 'issue' than anything else. If the site couldn't determine IP transport with confidence it would arguably be a misleading test to include.

David_W — Fri, 23 Dec 2011 15:56:17 GMT

Ahh, I see your point, seems reasonable enough to me
Back on track. I ran the IPV6 Firewall Scan and it came back as all in stealth so the router is properly handling IPV4 and 6 firewall traffic properly, which is good.

Re: 582n router trial initial thoughts

sjrinfroyle — Sat, 24 Dec 2011 19:26:59 GMT

Some initial first impressions from me:
1. The router uses a Broadcom chipset for speed and stability
2. The wireless performance is okay to average - the router seems to report 270Mbps but even sitting next to the router I only get 65Mbps. Does anybody know why this is?
3. IPv6 setup was easy and it worked first time - I got a 10/10 on http://test-ipv6.com/
4. The router's telnet functionality is poor and you can't do things like SNR tweaks
5. The router doesn't run very hot and it is raised off of the ground a bit so this will hopefully prevent overheating
Overall, so far not too bad! I am using the Billion 7800N at the moment as I like to tweak the SNR to get the best speed. Does anybody know if the Billion 7800N can be set to modem only mode?

Re: 582n router trial initial thoughts

David_W — Sat, 24 Dec 2011 22:09:22 GMT

Ideally you won't be using the Billion at all, that way we can leave feedback on the router as a whole, asking for a Technicolor modem to trial and then not using it kind of defeats the purpose of asking for the router doesn't it?
-edit: had a weird issue just now with the router, a DNS problem (IPV4) the first hop being way high after having trouble finding bbc.co.uk:

First hop (the router) shouldn't be that high should it?

My initial thoughts:

Boxed router was small enough to fit through the letter box. That's great for those of us who always miss delivery attempts!

Set-up was simple enough, worked first-time (would be nice if the RA-advertisements was disabled by default, allowing configuration with nothing other than username+password)

Hopefully this router supports TR-069 to simplify installation for new customers (and keep support costs low!)

I've remained sync'd at 2.7Mbps since installation (4 days), compared to 1.8Mbps on my own router

The wifi doesn't provide the throughput of my existing router, but covers the relatively large house (thin walls!) and is perfectly acceptable for a budget router

The wifi began rejecting associations (WPA/WPA2-PSK), I disabled autochannel and it began working. Suspect the process had hung, and changing the config simply caused the process to be restarted

Thanks to Ben I've flashed the plus net firmware for the 582n onto my own device and all is running perfectly after a reboot of the router an my PC.
Like some others here I had an issue with the ipv6 DNS not working by a reboot of the PC solved that (however flushing the DNS may have also worked and been quicker).
Interestingly these 582n's have internal connectors on 2 of the 4 antenna points for adding pigtails, so I may add a couple of external aerials to mine to see if it improve the wireless signal, as this is my only complaint so far with the router.

Re: 582n router trial initial thoughts

WelshPaul — Mon, 09 Jan 2012 18:51:20 GMT

Well i have been rather impressed with this router, only a few configuration quirks in the firmware so far. Even got it working with a mobile dongle and it's rock solid!
Did have the wifi go wonky donkey on me once, but it works very well, all round good little router.
EDIT: Forgot to add i have returned the router back to stock as received so nothing i have changed will effect any trial results. Had i not posted this reply nobody would be none the wiser!

Re: 582n router trial initial thoughts

battletux — Mon, 09 Jan 2012 20:17:41 GMT

What 3g dongle did you use? I am going to try mine to see if they work, would be great as a back up should my connection ever drop, and which it has yet to do with plusnet.
