My laptop with ubuntu sees pc (debians) essid, connects to it and everything is working. But after restarting my ubuntu it connects but does not work, i.e. ping fails. i issue iwconfig wlan0 and it gives that wlan0 is connected to my pc (cell: pc's mac). but not working. please help.
ps: with windows everything is ok.
