[Solved] Crash resulting in networking problems

Hello!

Recently my netbook (Acer Aspire One 150L) crashed because of me forgetting to plug in the power supply (Arrrgh!).

Since that crash my previously working network connection stopped working.

Since I am completely new to ArchLinux, I don't really know how to start looking for possible solutions to that problem.
In my dmesg output I found something like NETDEV WATCHDOG: eth0: transmit timed out, which I investigated. The only information I found was about people getting that message after a while, but all had a working network connection.

I attached some information that I hope is helpfull.

Thanks in advance.

(the probably relevant part of) dmesg:

r8169: eth0: link up

Re: [Solved] Crash resulting in networking problems

I realized that this seems to be a networking problem.

What I already tried:

Basic checking:
- checking the cable (works with another pc)
- restarting and checking the router (assigns ips correctly)
- assigning the router's MAC address to m

Specific stuff:
- ifconfig eth0 down
- ifconfig eth0 up
- dhcpcd eth0 (told me there's already one running)
- dhcpcd eth0 --release
- dhcpcd eth0 --renew (got another 169... ip-address)
- downloading and installing the r8169 driver from the realtek site (still the same problem)
- booting with noapci boot option

I pretty much reached the point where I don't know what else to try.

If you need additional information, please tell me.

Re: [Solved] Crash resulting in networking problems

Not loading r8169 on bootup and afterwards loading it with modprobe provided network connection again.

More information can be found at: http://bbs.archlinux.org/viewtopic.php?pid=423553

As a permanent solution, using another kernel seems to be the best way to go.
