Laptop manufacturer? Server(ISP) and router/gateway being used? More information might help.....
Our laptop will not pick up our modem. If I plug an Ethernet cable into the side, however, it will connect and run fine. But as soon as you unplug it the Wifi won't do anything.
The WiFi symbol has a yellow circle on it or something.
There's a function key or something with the wifi symbol, but I've done tried that and it doesn't work.
