So having read great reviews I decided to upgrade my 6 year old WRT54G (flashed with DD-WRT) to the 5th Gen Airport Extreme and get on the N bandwagon. Now just for comparison I decided to do the speakeasy speedtest on the MBP beofre the switch and with the DD-WRT I managed to get 21MB down and 6 MB up which sounds about the max on my cable. Then I switch it out and put in the Airport Extreme and configured it and ran the speakeasy speedtest again. This time the test comes in at 4MB down and 4MB up. I figure there must be a burn-in period for the extreme so I try the test a little while later and I get 5MB down and 4MB up. Not satisfied with the results I try to go in the Manual setup and see what else I could change. The channels were set to automatic as recommended and I did see a box to put the 5Ghz network name. I do that and create a new SSID for the 5Ghz and have my MBP join the new SSID. Re-ran the network test and now I get 14MB down and 5MB up. Didn't have a chance to play around more with it but I am sure I am doing something wrong or did I just pay a lot of cash to downgrade my wireless? Any suggestions would be appreciated. EDIT: I have tried downloading a few of the wireless range finding apps on Lion and they all quit unexpectedly. I tried AirGrab, iStumbler and AP Grapher. Does anyone know of a version that works with Lion?
