I have a Lenovo ThinkPad 15 with Windows 7. Last night something strange happened and my wireless router lost all of its information when I opened my laptop. For about fifteen minutes it was invisible from all wireless devices in the house. I restarted the router multiple times and that didn't change anything. Eventually it became visible again but the network settings needed to be reset. I was able to reconnect all other wireless devices to the router, other computers, phones, tablets but not my laptop. I can connect to the internet through a wired connection and I am able to connect to other wifi networks as I was using wifi at work all day. I contacted my wireless provider and there is nothing that can be done by the router and they say it is my laptop. I updated the drivers on my laptop and no change. I'm not sure what to do other than reset my laptop to factory settings. Any other suggestions would be appreciated.
