Well I do have Norton Studios which came with the laptop itself but am currently using Bitdefender if you're talking about anti-virus softwares. Also, there is a wireless button binded to function f12 and it's turned on. It has never caused me any issues since the purchase of this laptop almost one year ago.
Nothing questionable there. Running short of ideas - try removing the wireless adapter from device manager and rebooting to see if Windows picks up on it and re-installs - assuming windows 8 finds it this will overwrite the drive which we installed earlier which presumably wasn't working but see what happens!
Well Windows definitely reinstalled it, but the problem still persists. Also, I noticed that Hamachi is in my hidden icons most of the time when I restart my laptop even though I specifically disabled it in the startup section of the task manager. I don't think it has anything to do with the issue, but it starts out disconnected.
We have a lenovo pc with a wired ethernet which can access the internet using IP addresses but cannot handle DNS lookups either using the router address of 192.168.0.1 or the google dns service using either 188.8.131.52 or 184.108.40.206 as DNS server. The lenovo recognises the wireless adapter hardware and installs the driver for it but it cannot connect to the router at all. In summary wired ethernet connects to the router but DNS lookups fail, wireless connection to the router fails completely.
Three other devices (all phones?) are connecting wirelessly to the router and can all fully access the internet implying that the router is capable of wireless connection and resolving DNS lookups
