Network connection in Debian keeps dropping. Other devices are fine
 
Hey all.

I've got a problem with Debian I've never had before. My connection to the internet (and my router) keeps dropping without explanation.

My phone doesn't have the same problem, neither does the same PC when I'm on Windows

When I'm browsing the internet, it goes off, on, off, one in about one minute intervals.

When the connection is down, I cannot ping my router.

I left it pinging the router for about 30 minutes, and got 49% packet loss.

I did a fresh install of Debian Squeeze about a week ago, and the problem (as far as I can tell) has been there since the start

What could be causing such an issue?

Cheers

For ping lost, do you know the ping request or response is lost?

Were you using Squeeze prior to the Fresh install? Have you ruled out hardware as an issue (wiring, jacks, switch)? Is this connected by wireless or wired connection?

I don't know, when I ping the router this is all I get:

alarazr@Lindozer:~$ ping 192.168.1.254
PING 192.168.1.254 (192.168.1.254) 56(84) bytes of data.

Nothing happens, until the connection is restored then I get the usual:

64 bytes from 192.168.1.254: icmp_req=10 ttl=64 time=0.421 ms
64 bytes from 192.168.1.254: icmp_req=11 ttl=64 time=0.424 ms
64 bytes from 192.168.1.254: icmp_req=12 ttl=64 time=0.407 ms
64 bytes from 192.168.1.254: icmp_req=13 ttl=64 time=0.445 ms

I was using Lubuntu prior to this fresh install, but I have used Debian in the past with no similar issue. I think physical hardware issues are ruled out, because this PC also runs Windows and has no such issue. It is a wired connection.

I'm having problems troubleshooting this issue because I cannot think what could be causing it.

Hope you guys are still around to reply!

The hardware issue can be ruled out but driver issue still is pending. Different OS use different driver and network connection could be dancing if driver isn't correct.

alarazr 02-12-2013 06:54 PM

How would I go about checking which driver is installed?

scheidel21 02-12-2013 07:57 PM

lsmod will list the modules in use on the system including drivers. But if you don't know what you're looking for that probably won't help. In that case you probably want to follow this guide http://www.cyberciti.biz/faq/linux-f...card-is-using/
