Wireless - Mixing 802.11b and 302.11g base stations

Both 802.11a and 802.11g offer data rates up to 5 times faster than 802.11b. But 802.11g sales leap-frogged the slightly older 802.11a, due to backwards compatibility with legacy 802.11b products. Unlike A, which occupies the 5 GHz UNII band, B and G share the 2.4 GHz ISM band, letting G APs simultaneously communicate with B and G stations.
However, as many WLAN owners have noticed, there is a price to be paid for backwards compatibility: the presence of B stations can degrade G performance. To get the most from your 802.11g AP, it can be helpful to understand the "protection" mechanism that enables B/G coexistence at the expense of performance....

(Mostly posted for Lady, who mentioned something 'bout wireless being slower... I know you've got multiple networks in your area - although I don't know if this is the cause of your problem - it's certainly a new bit of information for me.)
