Will a 802.11b pci card slow down my 802.11g wireless network?

Will a 802.11b pci card slow down my 802.11g wireless network?

Will adding this slower card to a 3rd pc degrade performance of my 802.11g router connected wirelessly to 2 802.11g network cards on 2 other pc's?

no, it won't slow down the whole network.. it's just that the machine with the 802.11b card won't get the full speed that the 802.11g network can offer it.
