Linksys WCF12 802.11b Wireless Compact Flash Card – Support Forum

HP 2210 + WCF12 + Built-In Airport Card (powerbook) = SLOW! [Linksys WCF12 802.11b Wireless Compact Flash Card - 104082]

I dont know if any one will be able to help me with this as i guess the number of people with a windows OS PDA and a Apple powerbook are quite small. However iam using the CF card above in my HP 2210 and it works fine.... i have a built in airport card which works fine... together they produce a wireless connection to my PDA that makes take 5mins to load! I need help! Both my PDA and Laptop work fine independantly but why do i get such slow internet speeds when they are used together?? (oh and iam using broadband on my Powerbook so no speed probs there) Thanks. Iain
