Or alternately:

 router -+--> UPnP TV
         \--> MythTV server

What do you mean by that statement? All WiFi equipped routers act as wireless access points.

Any WiFi router that has only one radio will either do 802.11n or 802.11g, but not both simultaneously. Some WiFi routers have two radios (eg: Apple AirPort Extreme, Cisco E3000[1])

You can have an 802.11n and an 802.11g network running at the same time if you have two separate WiFi routers.

I have a Linksys WRT54G (802.11g) and an old Airport Express (802.11n) running side by side on the same network with no issues:

ADSL -- D502T -- AirPort Extreme ------- WiFi ------> 802.11n devices
                              \- Gigabit Ethernet--> Linksys WRT54G -> 802.11g devices
                                                 \-> Desktop computer

Hope this helps
Alex
