router dsl modem issue


Not linux related but I'm stumped.

I have a newish router connected to an older adsl modem. I had the router connected to cable modem for two years and it worked normally. Before that it was connected to the older adsl modem. Changed router to very old one and it didn't improve either.

Now I moved back to my old house and they only had dsl. So, connect it pots to modem to router.

Here is the issue. It looks perfect in every metric I can find. It "drops" tx/rx for a second or three and then works fine for 5 seconds or so. This is somewhat variable but always it will at some point drop. Problem is that when I connect modem directly to computer the downloading is stable.

When I use wireless broadband attached to router instead it is stable.

Where can I look? Direct to modem seems to prove modem is OK. Replacing the source with usb broadband seems to correct it also. Could it be the wan side of the router?

Thanks. ATT suggested a new modem based on his 15 years. Unfortunately based on my 20 years experience with them, they've always been at fault. Could it be some ATT issue?

I'd check or swap cables as a first step.

DSL commonly uses PPPoE. You did reconfigure the router, right?

Thanks for the replies.

Darn, I'll replace that cable. I haven't had a cable go bad in so long, I forget this stuff. Not a bad idea. Modem only shows upstream issues not between router and modem. Modem did show a lot of traffic on lan but I thought it was just a statistics error.

I've tried putting ppoe on both modem and router with no improvement. An unusual setting about private ip and public ip, tried them both. Not much I can configure in modem or router except user name and passkey.

Wonder if it is a dns issue. Might try using static dns at computers. Guess it could be tying up the deal.

OK, silly me. I re-ran the direct to modem test an it too fails so either modem or upstream.

I did try the cables and dns issues.

Thanks for the ideas.
