Diagnostic Help Needed - Vigor VDSL and Line Drops


[link to this post]
 
Hi,

Over the last 10 days i've been experiencing some drop outs (some days clean some days i get lots), as this my line has been stable for years i'm hoping that the problem is not at my end. But PlusNet aren't being very responsive and i'm just waiting for them to say it's because i don't have their router.

This is the last 24 hours on the TB monitor
My Broadband Ping

What i'm really curious about is the effect that i see on my local network .... The few times i've had line drops everything internally just carries on working... But this time at the moment when the "problem occurs" i see the response time from the router goes up ie:

then shortly after recovering i see that external pings restart ok.

I've tried to find anything on my local network that might be going rogue... but i've not found anything.

Can anyone thing of things i could/should check/test ? Any info that the router has that might be interesting ? Anything i should be collecting ?

Thanks .. Andy

Does the Vigor allow you to see processor utilisation? Wondering if something is doing a DDOS on your router and therefore it is struggling to respond to any pings because it is busy doing other things?

Hi, might be of no help but I had the exact same issue with a vigor 130, I changed it to a TP-Link W9970 in bridge mode and the constant drop outs stopped. I now use a HG612 and its rock solid, do you have different hardware to try temporarily to see if it stops? Even the router your ISP supplied, just for testing purposes.

Funny that was one of my first thoughts ...

Yes it does ... but when it's that slow the web UI just doesn't respond

I have the email interface enabled that reports on DoS attacks but I've not seen anything that matches ... really just a few port scans and the like.

I'll see if the console can give me the CPU figures and if that responds during an outage

i have the openreach modem somewhere, but no other router ... this router has been working for about 3 years without a hitch, so i hope it's not local hardware

unless something changed in the cab or at the exchange 10 days ago that has caused the problem.

If the UI doesn't respond then it does sound like an issue with the device.

Try the openreach modem in place of the 130,

What Vigor are you using?

What cabinet are you connected to, Huawei or ECI?

Yes it helps. The "DSLAM CHIPSET VENDOR : < BDCM >" says you're on a Huawei cab.

Are you running the "formal SIN 498 firmware" as detailed here? http://www.draytek.co.uk/information/our-technology/...
