The router can still do better since it can use the antenna with the better signal. Yes you don't get the speed boosts but you will see better (in most cases) over all performance.
...if your PC doesn't have a matching MIMO (SRX, etc.) wifi card?
I'm in the process of rebuilding a wifi network in my new home and need to purchase a new router. I've used a Motorola router for a few years now and it worked ok but I had to repair the connection multiple times per day. I want a nicer router but don't want to spend an arm and a leg. I wish they'd settle on an N standard so the prices would drop and I'd just get one for whenever I upgrade my PC next.
I'm currently interested in the Buffalo Airstation G54 Router (WHR-G54S) because it's on sale for $25 and has DD-WRT capability. Just learned what that means....do I need it?
I just want to make sure I'm not missing out on speed or range that can be gained from the "upgraded" G routers if they are still improved with basic G capability in my PC.
