I upgraded a radio from "B" to "G" the other day and began immediately to have a loss of connectivity when the client got further away from the AP. This client had no problems when the radio was a "B" radio. The only changes I made after installing the radio was to change the data rates in IOS to allow connectivity from 1 - 54 megs.
I then read that with "G" speeds you loose distance in terms of how far the signal will travel. I changed the config in the AP to allow 1 - 36 megs and the client began to work fine.
Therefore I have two questions:
1. Was this coincidental? I was under the impression that the client would automatically stepdown to a speed that it could "talk" to the AP with.
2. I also read that broadcast and multicast traffic is sent at the lowest speed allowed on that AP. If so, is it best to have only 1 speed defined on the AP and that speed being the fastest speed that will still allow connectivity?
