Connected to my wireless router at home won't give me internet access.
Several days ago I was connected to the Wifi router at home and everything works like a charm. Then I closed my Thinkpad and it was send to hibernate mode. Later at the university I was also able to connect to their WPA2-Enterprise (radius-managed) Wifi.
Back at home, I wake up my laptop, fired up the Wifi connection, got an IP, but then nothing works. I have no internet connectivity.
All ping requests to public IPs and Domain Servers timed out. The Wifi router was also not reachable via ping (which may be an security feature).
Things done so far
- Reconnected serveral times to the router
- Deleted the credentials of the networkmanager and entered it again
- Restarted the networkmanager using
sudo service network-manager restart
- Installed wicd and disabled networkmanager at boot by renaming it's startup files
rfkillto see, if there is something blocking the wireless interface
- Booted a linux live CD to see, if theres any issue to the configuration files
Booting my windows partition and connecting to the wifi router give me internet access as usual.
Linux Mint 17
wlan0: Intel wifi interface
What else can I do?
