I have 2 televisions that are not compatible with AES encryption. They work just fine with WPA-TKIP. TKIP is not part of the final 802.11n specs. Apple has disabled TKIP with firmware. I want to hook up my TVs to my wireless g-only modem, and hook up the macs to the time capsule (2nd gen.) The TC is connected to one of the ethernet LAN ports on my modem, so it is in "create a wireless network" mode (so no double NATing or guest network.) I cannot seem to make the TC n only mode. Any suggestions?
