Using 802.11g with 802.11b type laptops

[ranjan2001]

We plan to buy 802.11g type APs for our wifi network, but we do have laptops with 802.11b, someone told me that the g type will only have 54mbps speed if all the computers have g type cards installed, even if 1 of them is running on b type card the data transfer will fall down to 11mbps for all to accomodate that one.

Is it true, I thought it to be a node to node connection means, the AP will be passing the data & Negotiate the speed as per the client computer & do the data transfer at required speed.

Hope some of you can clear the doubts.

Can anyone confirm this??

Yeah it is so, in the presence of 802.11b, the 802.11g would be depressed across the Network on all nodes. It depends on the Brand, some will go al the way down to 802.11b, most will lose about 40%.

Thanks Jack,
So the solution is to disable the B type card of the laptops & connect the G type to them, I guess that should work.

This still leaves me wondering that on an airport where G type routers are networked to give 54mbps wifi speed, they will mostly be functioning at 11mbps bcoz one or the other laptop in the network would be using 11mbps Btype card.

i recall reading about some routers that were able to maintain both g and b traffic separately, and that was nearly a year ago. good luck finding the current and true answer

I use both B and G traffic on my home wireless network using a linksys router. My laptop runs at the full 54 Mbps while my Mom's only runs at 11 Mbps so networks can run in a mixed format.

Sorry about the double post.
