ADSL Broadband slows down until reboot

My ADSL broadband, on TalkTalk slows down every 2-3 hours I find and it works fantastic when I reboot.

My download speed is 4Mbps after a reboot, and at pingtest.net, I get an A, however, after a wee while, these sites struggle to load.

I have my own router. I have tried a Linksys X2000 which I am using right now and I have the same problem with my Netgear DGN2000.

What could be wrong?
This is really frustrating!!

You need initially to look at the router stats i.e. attenuation, noise margins and connection speeds and see if the noise margin is lowering to a very poor level eventually

most of 'em in his X-post!

This is a really frustrating problem and I would appreciate any help/suggestions

I don't seem to be experiencing any disconnections as such, just very slow internet speeds, which go as low as 0.2Mbps (download)

If this is not sorted soon, I will definitely be moving away from TalkTalk. Phoned their customer support yesterday, was abysmal, the guy, was obviously reading off some troubleshooting guide asking me the same questions, and kept mentioning disconnections and things which I had not stated as being the problem, finally to reach the conclusion that "We cannot troubleshoot with you any further as you are not using one of our supported routers". I then got put through to Customer Services who want me to take out a new 12 month contract before they will supply me with a new free router, and I am not willing to pay for one. The agent emphasises how the contract would be cheaper, but HELL NO, I don't want to get roped into a contract if I have to spend my life rebooting the router!

I cannot find SNR on either router!

Using speedtest.net, my internet speed slows from 4.5ish mbps to 0.8-1mbps sometimes ~2mbps.

Seek "Noise Margin" or any noisy thing!

Decide which of your x-posts you are running with & delete other. I choose this as earlier.

This sounds like it could be a high resistance fault on the line. This could be caused by corrosion of the various joints in your telephone line.

Does the phone line work ok? Is there any crackling/noise on it?

If there is it's worth getting BT to look at it, as no matter where you move to the problem will likely remain.
