Wi-Fi connection issues

[tarheelsfan23]

I am using a westell 6100 modem with and airport extreme. We have 4 iPhones, 2 iPads, 1 mac book and and iMac that connect without problems. I have a Lenovo think pad t540p that could also connect to this network until recently. Now it will only recognize one of my 2 networks and will connect to the one network with limited access and no internet. I need help figuring out why the Lenovo won't connect with internet access and why it won't recognize my other network. I would appreciate any ideas and would be happy to supply any other needed information. Thanks.

Check the properties of the wireless device on the Lenovo. Pay particular attention to the TCP v4 properties and check to see if some odd DNS settings have been entered. Should probably be set to automatic DNS.

Thanks Brian. Will check and see if this solves the problem.

have you made any new policies on the router?
