Long story short, my computer is in a room away from the router. A wireless option is my only choice. My wireless PCI adapter is 5ghz but my router is not. I can get pretty bad lag during the evening when trying to play games over wifi. My download speed is only 4mb. I was wondering if a 5ghz router would improve my connection stability? I also looked at powerline adapters but I would be unable to plug either into a main socket (they'd have to go into extension sockets).
