Hi. I have an aluminum iMac with iSight. it's probably close to two years old now. The past week trying to download anything has become brutal; iTunes downloads, limewire, trying to download songs from sites like rhapsody etc. Attempting any kind of download has become problematic. My airport connection appears to be at full strength (full bars), but all downloads stall after a few seconds. I'm even having trouble sending files to clients through email. Whether sending or receiving files, the connection starts out very strong then drops down to maybe 20 kb/s and then dies altogether, despite displaying a full wifi signal. I went into system preference/ network and checked the connection. The computer reports that my Internet connection appears to be normal...hmmm. Has anyone had a similar experience? Any suggestions? Thanks. By the way I'm in the Boston area and RCN is my service provider, not sure if that makes a difference. I get my connection from a linksys modem attached to a pc downstairs. Thanks again. Oh. Also, I should mention that I'm using the same wifi connection for my iPad and iPhone without issue, which I would imagine means the problem may lie with some glitch or setting involving my iMac.
