i'm trying to diagnose why our company's wifi network is running really slow. the network is wpa2 encrypted, and there hasn't been any other traffic accessing our network other than the 5 computers in our office. i've tried using connections on other ports (ftp,ssh,bitorrent), all of which run fine. however, when browsing the web (port 80), everything is extremely slow (2kb connection speeds). any ideas on unix (or gui) tools i could use to further diagnose this issue, or immediate thoughts on what the issue might be? we're all on macs in the office.
