I'll start off that I'm new to Linux. A couple months ago I tried installing Ubuntu 11.10 on a laptop (HP). The install went great, however when setting up my wireless network, it caused my router (Buffalo) to crash. I could not login to the routers http interface even on a wired PC. I removed power from the router and shutdown the laptop. Powered the router back up. Everything worked on the network again. I powered the laptop again and the router crashed again. The router had been working fine for months and has worked great since trying. It has the following firmware: DD-WRT v24SP2-EU-US (08/19/10) std.

I tried to install Mint 12 last night with the exact same issue. I turned off wireless on the laptop and plugged it into the router. I was able to update so Mint tells me I have all updates applied.

I Googled a bit and found people stating to move your wireless router to bg only. I tried that with a little luck. I was able to browse the internet for ~10 minutes on wireless before the router crashed. Again replugging the router fixed the problem and without powering up the laptop the router has been solid today.

I did some more Googling and found found this post

It does seem to fix my issue.

echo "options iwlagn 11n_disable=1" | sudo tee /etc/modprobe.d/iwlagn.conf
sudo modprobe -rf iwlagn
sudo modprobe -v iwlagn
sudo service network-manager restart

I do still have my router set to BG only. I will try allowing N, but it is working for now.
