Wifi connection appears as limited - Dell Inspiron 7537 - Windows 8

I bought refurbished Dell Inspiron 7537 laptop and received it 2 days back. I am having issues in connection with my home virginmedia wireless network. On day 1 system was not connecting to wireless at all but after couple of windows restart and wifi router restart; it connected and started to work properlty.

But since yesterday when i restarted my machine and windows performed some auto updated. My connection is appearing as limited and no internet access (under network and sharing). I have restarted wifi router and laptop many times but still it is appearing as limited connection.

Please help.
