Are wireless g computers compatible on wireless n routers?

Answer 1

Wireless g are only compatible with b. When you shop for a router you will see on the package what that model is compatible with. It will 802.11b/g or 802.11a/n or what ever one you are looking at.

Answer 2

All wireless networking standards are backward compatible with one another. So, a Wireless-n (802.11n) router is backward compatible and can accept connections from Wireless-g (802.11g) and Wireless-b (802.11b) adapters. The same is true with Wireless-n adapters attaching to Wireless-g and Wireless-b routers. They all play nicely together.

Now, having said all that, if what you are after are the faster speeds of Wireless-n, then you need to make sure that you use WPA or WPA2 encryption because Wireless-n will not permit WEP for the higher speeds such as 144 or 300 Mbps. You would be limited to the highest speed of Wireless-g, which is only 54 Mbps. The same is true for the more modern Archer routers (802.11ac) that offer speeds up to 3.2 Gbps.
