I recently tried to dual boot Elementary OS with Windows 7. I can see WiFi networks but when I try and connect to them, it asks for the password then tries to connect. After a while it stops and asks me the password again. I'm using a TP-LINK TL-WN881ND Wireless Adapter. Whenever I try to connect to the internet via Ethernet it also doesn't work. It tries to connect me to the network and then disconnects. This is the output from sudo lshw -C network. Thanks for all your help in advance
