Wireless network doesn't work on Asus Eee PC T101MT

[Igor Novikov]

I recently installed Oneiric Ocelot on the Asus Eee PC T101MT, but now I can't access the internet. I connected via wireless network, and network applet, as well as ifconfig, says everything is fine. However, I can neither resolve google.com, nor even ping the router, which is at 192.168.0.1.:
