My Dell 7010 suddenly stopped connecting to my motel wifi. The antenna w network card USB connected seemed at fault so I got another one. Yet the new one also failed to connect. Here's where it gets interesting.... If I use my phone by accessing WiFi then USB theter with the same phone it connects. Now this is a workaround so I am curious why my antenna will not enable me to connect with WiFi but my phone connection will? Please advise
