I am currently chasing down an issue with my wireless network that I'm quite stumped by. My configuration is as follows: Cisco cable modem > Cisco/Linksys Wireless Router (WRT310N) (Wireless clients connect here obviously) > Netgear ProSafe Gigabit switch > Wired clients (desktop PCs, PS3, XBOX, etc). When I run a speed test on my wired system(s), I achieve consistent 60Mbps down and ~3Mbps up speeds. I'm reasonably happy with that. I get these same results whether plugging into the modem directly, the router ports, or the switch. When I run a speed test on my wireless system(s) (including MacBook Pro, MacBook Air, or Dell Precision M4300), I get results between 9Mbps and 11Mbps. The Dell is Wireless G and the two MacBooks are Wireless N, and as stated, the router/WAP is Wireless N. I cannot for the life of me figure out why there'd be such a drastic reduction in throughput on the wireless clients. The ONLY theory I've come to is that possibly the MacBooks use a different implementation of N (it's STILL not standardized is it?) than the Cisco/Linksys router, but that doesn't explain why the Dell would be affected. I've searched and searched, but haven't found examples of bandwidth users have gotten with current-gen MacBook Pros/Airs mated to Airport Extreme base stations. I'd love some examples here if possible. Any of you guys have thoughts on this? Things I can try? I've already done the basic stuff - minimizing interference by moving base station, etc. Nothing seems to help and I'm lost. Willing to buy Airport Extreme but want reasonable evidence that it will help in my situation.
