Hey guys this is my first post ath this forum. I'm about to buy a new ibook G4 for use in college and home. I noted that it has airport extreme built in, i wanted to know if AP extreme is compatible with 802.11b, since my networkl at home is 802.11b. Is AP extreme compatible for both b/g?. If not, what do you recomend me to upgrade my home network. Thanks.
