strange wifi behaviour

This sounds stupid but may work.. Your mac address might have to be saved to your router before it allows access via wifi.. I had that b4.. Get into your router via the admin htt protocol.. Every manufacturer has a diff address.. So no point in me giving u mine.. Give it a try, in my experience with win 7 a cable connect and wifi connection are given the same level of scrutiny.. I.e. The firewall will hinder them bothe exactly the same.. Best of luck.

OK still no luck we use the 192.168.0. addresses I get a new ip when i plug in and when using the cable. Have cleared the hosts file. I also downloaded malwarebytes antimalware. Still no luck. My next port of call will be a wifi hotspot to see if this happens there. I have loaded the MAC addresses as well.
I will report back if I can solve this.

Finally solved the problem had to load new firmware on wireless router.
