Re: Inconsistent speed- low SNR high attenuation

Different attenuation - Good spot Anotherone.  Think I trust the Netgear one over the other..  It better fits the line speed!

Re: Inconsistent speed- low SNR high attenuation

Just got back from work and found that internet had disconnected so had to restart router again. Had to do this twice to get a connection that would hold. Once things were ok I have compiled the information you guys have requested which I have attached below.
Interestingly what do you make of the tracert results? Seems to be pinging back sky then plusnetHuh
No extensions in phone socket. Master socket is the only one in whole house and run 3 DECT hansets from this point. I also made sure the bell wire was not connected in the faceplate.

Re: Inconsistent speed- low SNR high attenuation

I've just had to swap back to tp link router as old netgear (sky router) just kept dropping the connection and I had to restart. So here are some up to date stats with tp link router.
Ran tracert again and everything appears to be normal this time so my guess is old router must be locked to sky

Re: Inconsistent speed- low SNR high attenuation

There's something odd going on here - it looks like you have two active services on your line.
The traceroute when you were using the Netgear shows you connected to SkyBB.
The traceroute when you were using the TP-Link shows you connected to Plusnet.
As it is technically possible to have both services active on the one line, with the difference being determined when you log in, it's likely that the Sky router is hard-wired with Sky's connection settings. I would imagine that you may have paid in advance for the SkyBB connection, or they haven't ceased your account due to a slip-up at their end. I would check with them, as you don't want to be paying for two separate services on the one line.

Re: Inconsistent speed- low SNR high attenuation

You are certainly right there Brian, which explains why speedtest.net last night showed sky as the provider. I really am surprised that BTw/OR have made this blunder, the Sky service should have been removed when the Plusnet one was activated. Actually I'm not surprised, they are a bunch of ...........
Simon, those speedtest results are much better and pretty much what they ought to be. With the current BT IP profile your Current Line speed should rise to 5.1 soon which should give a touch more speed (assuming no congestion at the time). If this remains consistent for a few days, then the issue was on the wireless side and we can then look at that in  more detail.
Now just thinking ahead at the moment, you are in the test socket, using a filter presumably as the face plate is off. Do you have a 2nd spare filter perchance?
Now back to this Netgear. First of all, the drops this afternoon. Did you have any thunder and lightning in the vicinity at all?
2nd, did you not change the login details in it, to your Plusnet ones? If not, you should be able to experiment with that off-line.
Just unplug the computer Ethernet from the TP-Link and plug it into the Netgear and power up the Netgear. No need to disconnect the TP-Link from the phone line - definitely don't do that!
Anyway login to the netgear and find the broadband PPP Internet login details and see what they are, and see if you can change them to your Plusnet ones. Click on anything that suggests they are remembered etc. Then reboot it and see if they remain there. If so, power it down. After 30 seconds or so, power it up again and see if the Plusnet details are still there, if so success, you should be able to use it - but not at present then, we'll keep it on standby.
What exchange are you on? Plusnet will need to get on to BTw tomorrow to get this Sky service configuration removed from the exchange, it just should not be there.
Post up some more stats so we can have a look and see how it's going,  try and post the Uptime as well. You could do another speedtest as well if you haven't already Wink
Lastly did you have a look to see if there was updated firmware available for the TP-Link?

Re: Inconsistent speed- low SNR high attenuation

If it's an old sky router, it might be locked to sky. It might be possible to unlock it, by flashing it with the standard netgear firmware, depending on the exact model. If it is a DG934 see here: http://www.kitz.co.uk/routers/skyDG934.htm
However, if it's such an old model, it may be hardly worth the effort.

You certainly need to watch out for Sky http://forums.moneysavingexpert.com/showthread.php?t=5034918

Re: Inconsistent speed- low SNR high attenuation

I've checked the Tags on the line and there's certainly on us on there.
It would be worth seeing if you can do the steps that ejs has pointed to in reply #35.

Re: Inconsistent speed- low SNR high attenuation

Thanks for looking Chris. So I'm baffled a bit by the traceroute in reply #31 as it would suggest connecting to a Sky gateway? I'm sure someone with more knowledge in these areas could explain.

Re: Inconsistent speed- low SNR high attenuation

The last post was from a Plusnet IP address but I can't check the earlier ones

Re: Inconsistent speed- low SNR high attenuation

Well we expected the last one to be Plusnet, so you can't see the IP address for post #31 and do a whois then?

Re: Inconsistent speed- low SNR high attenuation

Hello everyone
I've had a busy few hours trying out your suggestions since returning from work. I attempted to input plusnet settings into the netgear router but this was not possible as ejs mentioned looks as though settings are hard wired into the router - I tried to flash original firmware but further digging I found out flashing with the netgear recovery utility is not possible on windows7. I also had an old sagemcom f@st2504 modem which I tried to flash with custom firmware but unfortunately I ended up bricking it which I was really puzzled about then I found out that there were in fact 2 f@st2504 firmware: f@st2504N (cable) and f@st2504 (adsl) guess which one I flashed with  Embarrassed
Anotherone - the netgear router would only stay connected for maybe 10-15 minutes and then disconnect, I'm guessing maybe it was connecting to sky and then disconnecting because I login credentials were not checking out with sky server, whether this is even possible I don't know, but definately no thunder storms here. I do have a sprare microfilter would you suggest swapping it over? I was even thinking of buying a new bt nte 2000 filtered faceplate. I'm connected to the wideopen exchange in Newcastle which doesn't seem to be fibre optic enabled yet Sad
I've also gathered some further stats. I don't know what has happened but the connection has been pretty stable I've been waiting for a drop in speed or connection but this hasn't happened yet. I've also changed the wireless broadcast from 20mhz only to 20/40mhz to see whether this would help

Re: Inconsistent speed- low SNR high attenuation

Well the speedtests are considerably better and pretty consistent, so it looks as though it could be a wireless issue. I would tend to leave the wireless settings as they were, except maybe try a different channel first. If you read the article I linked and go and download the inSSIDer software you can then have a look and see which are the clearest channels around you.
On the Stats, the ES and SES errors haven't increased in the last 4 hours, so I'm wondering what caused them before.
Can you go and look at the IP address that  was on your post #'31, it's in the bottom rh corner and post it here.
What I was thinking with the 2nd filter, was that if we were seeing a large error rate was to try double filtering the DECT base station in case that was causing them.

Re: Inconsistent speed- low SNR high attenuation

633 ES earlier, 663 ES later. Which makes sense since the number of uncorrectable (CRC) errors increased, so there must have been some seconds in which they occurred.
