Any reason to disable B when all clients are G?

Unanswered Question
Jan 12th, 2009

Is there any reason to disable the ability to connect with B devices when all of our clients have G devices?

Would there be a performance decrease having it setup in a mixed mode?



I have this problem too.

If the AP is set for mixed mode, and there is a "B" client in range (whether it's connecting to your AP or not), it will degrade throughput because the AP still has to pay attention to see if that client tries to connect or interact.

If you truly have no B clients, shut down the "b" modes.

Thanks for the reply. So because I am very sure that there are no B clients within range there should be no performance decrease, correct?

*IF* there are no 802.11b clients, then there is still "a little" degradation, because the AP must still check for 802.11b signaling.

If you're not using it, shut it down; it also saves processing resources, memory resources within the AP.

Actively shutting down resources that are not used is standard procedure (or should be); aside from the resource/efficiency savings, it removes that code that could cause (or reduces the chance of)"undocumented features" and removes the potential for security holes.

"Because you are very sure" doesn't take into account things you haven't thought about, or the twit down the street with a Pringles can.

Good Luck
