#5 Disconnect Wireless G Clients for Best N Performance
Wireless N is backward compatible with wireless G, and even the ancient B standard. However, the traffic on the network is managed differently when older adapters are connected to an N network.
This has a negative effect on the speeds and performance. So if you aren't getting the data or throughput rates you desire, make sure that the network is only offering connections to other wireless N clients.
You can actually limit the types of clients who are allowed to connect, forcing the router to allow only wireless N connections.
If you want to do this, log on to the web-based configuration utility and change the setting in the wireless section.
If you still want to support wireless B/G clients, consider using any old wireless G routers or APs.
You could plug the wireless G router or AP into the back of the new router. Make sure that each is set on a different non-overlapping channel: 1, 6, or 11; or just 1 or 11 if using channel bonding on the N router.
Then make sure you allow only N connections on the new router and/or indicate the wireless type in the network name (SSID), so users know which they are connected to.
