This is either a failing wifi card, it's turned off or the security of the wifi is WEP (discussed widely why it matters.)
Then again a neighbor installed their wifi router and it's on the same channel.
I am running two laptops on my home router. Everything has been performing fine for the past 4 years until recently. I am now losing internet signal while surfing the web and when i try to reconnect, my laptop cannot find my router or any other router nearby. When i restart my laptop, it is able to find the router until the next occurance. This is only happening on one of the two laptops, so i dont think the problem is at the router. Any suggestions?
