Home network won’t workLocked
I have cable Internet through Comcast. There is a wireless router next to the cable modem. My downstairs computer picks up the wireless signal and it works well. The upstairs computer used to pick up the signal and worked well, too. Then I added a network key to secure the network from outsiders. The upstairs computer stopped receiving a signal. Nothing I have done since made it work again. I set up the upstairs computer EXACTLY like the downstairs one. I removed the software, reinstalled it, but no luck. Please – any help? THis thing is driving me nuts.
