My cb2 connects to a wired router and wireless router. After hours ( fewer than 24 hours) connected to the wireless network, my cb2 cannot send or receive any data through my usb wifi adapter and IP from wireless router DHCP is lost. I can see cb2 still connects to my wireless router by command iwconfig wlan0, but cannot acquire a IP from DHCP by command dhclient wlan0. I tried everything I can, but still cannot acquire a IP. At last, I have to reboot my cb2, after that everything is normal.

My wired network always works well, so I think this is a wifi related problem.

Chipset of the wifi adapter on my cb2 is 8188eu. My cb2 runs on cubian OS.
