I had bought a new lenovo laptop with win8 . when in UK the wifi worked perfectly fine with no issues. but now when I went to India its past 2 weeks I am struggling to connect to the internet. I bought a new beetel wifi router where I use a sim card in it for internet purpose. The laptop detects the device but I am unable to connect to it as when I enter the device security key in the option for the wifi conectivity it says' limited connectivity. I tried disabling other network adapters and using just wifi adapter, network troubleshooter but didnt work.. Please somebody HELP!!!
