I have a wireless router that I have been using for about a year with no problems. I have been able to connect to the router wirelessly with multiple devices at the same time (2 iphones, ipad, smart tv). Last week, I used my laptop to wirelessly connect to the router. This was the first time I tried connecting with this computer. I was able to connect fine with no issues and use the internet. The next morning, no other devices are able to connect wirelessly. On each device, I am able to see the router name in the available list and it shows a full signal. But when I attempt to connect, it tells me unable to connect. When I try to connect using the laptop, I am able to do so, but I cannot with any other devices.
I have tried unplugging the router and modem and replugging them back in. I have also turned the wifi off on the laptop.
Any suggestions on what might be the problem?
