Can't game on wifi

[Dammie]

As the title says, when I try to game on my laptop on wifi, it just won't connect to the online services.

I can reach internet though, since I am writing this on the laptop.

As soon as I plugged in a ethernet-cable the games would connect to the online services, but the problem is that I can't get that cable in my room and I can't game in the living room next to the router either.

Is there a way to solve this problem so I can just game on wifi.

I have tried disabling firewall and create exceptions etc. but that didn't work.

Thanks in advance!

Powerline network adapters are probably your best option. Here is Tom's 101 on powerline -- http://www.tomshardware.com/reviews/network-switch-guide,4047.html#p1

The newest standard is AV2. It will provide the most bandwidth.
