I have a feeling you're not the only one who misunderstood my results.
Wireless-n can be utilized in 2 frequency ranges: 2.4GHz; and 5GHz.
Wireless-g can be utilized in 1 frequency range: 2.4GHz.
My Tablo would disappear from our network if it connected to wireless-n @ 2.4GHz.
Connecting to wireless-g @ 2.4GHz is my workaround.
I'm unable to even test connecting my Tablo via wireless-n @ 5GHz, cuz of distance, and obstructions between the Tablo, and wireless router.
