Weird Regular (as clockwork) Router disconnect problem

Post by simg » Wed Jun 25, 2014 11:47 am

Hi,

I'm having a problem with my broadband that may or may not be related to the Routertech firmware (I'm on 2.96) but it's weird and potentially interesting and since you guys are experts, I thought I'd ask.

My broadband disconnects at regular(ish) times throughout the day. I've been onto my ISP and they've sent me a log of my connectivity (see below) which shows the oddly regular pattern of disconnects. They say its the "user" (ie my router) that is dropping the connection. They also say they won't investigate further unless I swap out the router (which seems fair enough?)

Image

Another, possibly related?, problem that I have is that sometimes it appears the router runs very slowly. That is even when visiting the admin screen the page downloads noticeably slowly and sometimes images (like the routertech logo) don't download at all. This happens every few days which I've assumed is caused by a memory leak (or something) in the Routertech firmware. A reboot fixes the problem. Nothing like that happened with the OEM firmware and this by itself isn't much of a problem. I only mention it incase it's related to the connection dropping.

Note: There is no obvious correlation between the connection drops and the slow downs. The connection drops even when the router is running at apparently normal speed.

Post the firmware's system diagnostics (after removing all sensitive information).

Apologies. I didn't realise that diagnostic takes a while to run and I took a long pause to mean it was completed.

This is the output immediately following Network Statistics.

Re: Weird Regular (as clockwork) Router disconnect problem

Post by thechief » Wed Jun 25, 2014 7:43 pm

Well, the disconnections don't seem to be related to anything the firmware is doing. I can't see any obvious reason. The line stats are good, and the connection is in interleaved mode, therefore everything should be stable. The problem may well lie in the interaction between the DSL modem driver and the ISP's equipment. If so, there is little you can do - but perhaps the Router Stats Logger can help.

PS: you may want to remove all the IP addresses in your last post.

Re: Weird Regular (as clockwork) Router disconnect problem

Thanks for the suggestion re: Route stats logger, will check that out. And thanks for your time and assistance.

Don't worry, unless I missed some the IP addresses are anonymised :) ie not the real ip's

If I may, I am wondering if it might be worth investing in a Billion BiPAC 7800DXL router http://www.amazon.co.uk/gp/product/B00B ... uctDetails. I have read that these have better signal / noise filters which make them significantly faster and more reliable on poor quality broadband connections. Do you know if this is true or is it likely to be marketing bullshit?

Well, I wouldn't describe your connection as poor quality. The line stats look decent, but there's obviously something that's interfering somewhere.

I wouldn't spend £127 on a router - but even if I would, I would first want to assure myself that it would solve my problem.

Re: Weird Regular (as clockwork) Router disconnect problem

Post by simg » Wed Jun 25, 2014 8:16 pm

It seems odd that it's so regular, and yet not entirely regular.

Like it caused by a fairly habitual person turning their microwave on or something?

I'll monitor the situation for a while with Router Stats logger.

Many thanks :)

Re: Weird Regular (as clockwork) Router disconnect problem

Just an update.

I have managed to fix the periodic disconnection problem by moving the router closer to the BT main socket and using a much shorter cable between the router and the main socket.

The router itself still suffers occasional slow downs and needs to be powered off every few days. I don't care particularly about getting a solution to this, I just mention it for your info.

Router *just* did a slow down so I ran a system diagnostics (which took about 10 minutes to complete), the results of which are posted below.

Re: Weird Regular (as clockwork) Router disconnect problem

Post by thechief » Wed Jul 02, 2014 10:40 pm

I can't see what would be causing the slowdown, although there are some suspects (e.g., darkstat may have memory leaks or be a memory hog).

Tips:
1. you might want to read the firmware FAQ for things that may make the system unstable, and what to do about it;
2. you might want to set the modulation manually to ADSL_G.dmt;
3. your environment is fragmented - you might want to defragment it;
4. if you find that you have to power off every few days, you might want to create a cron job that will reboot the router for you every 2 or 3 days or so (at a time of the night when you know that you will definitely never be using the router).
