What DSL modem should I buy? [more inside]
My old PC laptop runs perfectly as do any tablets on my apt public wi-fi. The iMac computer (Snow Leopard), slows to a halt and won't get to pages after a few times. I have done several things such as reset PRAM, gone to /Library/Preferences and moved all the files in the System Configuration folder to the Trash, and restarted Mac...The second bit helped for a week and now it is doing it again, no matter what browser. MacKeeper says the computer is alright, and airport utility just tells me I am connected to the internet. (I've done the reconnecting and assistant and diagnostics but nada...) I cannot figure this out and I have scoured the net. If somebody was downloading a ton on it, I would at least understand but any other devices work fine. My husband wants throw it out the window. Any ideas?

Is there anything I can do to improve wi-fi connectivity in a small area (three rooms) when dealing with a large number of other signals? I'm in a high-rise apartment building in a city; after letting inSSIDer run for a while, it shows that I'm competing with 125 other access points. My signal is okay in the first room, fair in the second room, and unusable in the third room. I'm using DD-WRT -- are there any settings I can tweak that might help? [more inside]
iPad 3G cellular vs. wi-fi -- which takes precedence if both are active? If I have 3G cellular turned on, while sitting at home with my home wireless, does it use the faster home wireless? Or does the 3G just clobber everything and gleefully rack up data charges? I've been turning it on and off as needed, but that's just annoying, so I'd like to get the question settled once and for all.
