I need advice. My son has a Titanium Powerbook with b wifi card not a g. It seems to have poor range in a WiFi network and from the beginning December 2002 would not work on campus in certain locations that Windows laptops worked fine. The current problem: he is just off campus and in his apartment he gets only intermittent connection with University Network. Good connection occurs on campus with the Powerbook in most locations. What can a Mac user buy to act as a network extender, that is, receive the campus WiFi signal and then rebroadcast (network) to his Powerbook when the Powerbook is in his apartment. Apple WiFi solution ( Airport Base Station ) is too expensive for him to buy for the apartment even though it has a better range (I have been told) than his Titanium Powerbook. The cheaper Airport Express does not link wireless signals according to a Genius a Apple Store that I talked with about this problem. Any ideas on what can be purchased to cheaply get reliable networking and is Macintosh compatible? I believe a 802.11g Wireless Broadband Router is needed but all of the cheap ones ( with rebates less than $50.00 total cost ) are WINDOWS products. Any ideas would be appreciated.
