After several long (painful) weeks with Bell Sympatico's Tech Support, they've sent me a Siemens Speedstream 6520. I have the internet running on my iMac G5 (OS X 10.4.9) and am trying to (wirelessly) network it with my husbands PS3. The Playstation will automatically locate the network that we have set-up but the signal is very low (7%). No house phone line or other interference that I can think of. What to do?
