Same SSID for 2 AP's of Different Speeds

[Ethan-H]

I have g-speed router now as the main. One room with thick brick walls is getting very poor signal. I am going to run a Cat5 to the room and hook up a new n speed router (with DHCP turn off) there as an AP. My understanding is that for roaming purpose, the n-speed AP should have the same SSID as the AP in g-speed router.

My question are:

1) Will the speed stay at n-speed when I am connected to the n-speed AP in the n-speed covered area and the speed be downgraded to g-speed when I roam to the g-speed covered area and is connected to it? Or will the n-speed AP downgrade to g-speed always?


2) What if I forgo the roaming capability and set the n-speed AP with a different SSID? What will this do to the speed in situation I ask about in 1)?

Hope I have explain my question clearly enough.
