WiFi connected but no traffic/name resolution

Post by upsfeup »

Since a few days, I'm having problem with Wifi.

After suspend, the wifi would just not work. In the beginning, a reboot would solve the problem but now, not even that.

So, I can connect to the wifi network but then there is no traffic and seems that no hosts can be reached, Including the gateway router:

Open terminal and run this

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
Then you can post the contents of the wireless-info.txt file it creates

Do you have UFW enabled in Linux Mint? Or MAC filtering on the router?

UFW is disabled. No Mac filtering.

It actually worked ok after installing Mint a couple of months ago. But Last week i started to have connecting problem and it would not connect after suspend and would connect only after restart. Now, not even with restart.
Other devices have no problem connecting.

Try booting from a Live DVD/USB and see if it has issues

Go into Network Manager and disable(ignore) IPv6 for all connections
