I received my T570 Thinkpad laptop a couple of months ago and have had no problems connecting it to my home router. Yesterday, however, it stopped connecting to our home WiFi. It recognizes the WiFi network but it asks me to put our Security key/password in. I've entered it correctly but it then says "Can't connect to this network". All other computers, phones, etc. aren't experiencing problems connecting, and when the laptop is plugged in directly to the Ethernet cable it works fine. Today I took my laptop to a friend's place and was able to connect to their wireless network. Any suggestions on how to fix this would be very much appreciated - thank you!
