This is not specific to Macs, but I have a question regarding wireless antenna... (I searched around but the forum but nothing jumped at me...) My friends recently moved into my apartment complex. If possible, we'd like to share my cable modem connection. I already have a modem and a wireless router. (Nothing special, a standard wifi Netgear router...) Currently, my 2 roommates and i share the cable modem on three laptops. The friends moving near out place have a desktop. My friends' new apartment is quite far away, probably about 200+ feet. I tried carrying my PB 12" to their place and got 1 bar (but inconsistent connection) in their front door. I'd need to go 20 feet or so more... Questions: 1) My friends will get a desktop wireless card if we can share the connection. Will desktop wireless cards have a better reception than laptop cards? How much will I gain? (Just an estimate would be great... if anyone has experience dealing with this kind of stuff...) 2) My friends are on the second floor while I live on the first. Would it be better to put the wireless router on the second floor? 3) What are the options in boosting the antenna broadcast strength? Thanks for any info!
