I recently purchased a new airport extreme and express to replace my older G equiment. I have the extreme connected to my dsl internet and a few computers. The express is in a different room and is in wireless-bridge mode with a computer connected to it. So basically, I've got two rooms pretty far apart that I didn't want to run an ethernet cable between, so the express is acting as my internet bridge. The extreme and express are the only wireless networking devices used and they are set to 802.11n only, 5ghz. When I transfer a file between a computer connected to the extreme and a computer connected to the express, I get an average of 3.7mb/s (Wireless N should provide around 8-11mb/s). I've tried the following things: - I've transferred files through ethernet through the same computers (obtained 50mb/s) - Had the express in the same room as the extreme and still got 3.7mb/s - tried 2.4 ghz mode, g mode, robust networking on/off, wide channels on/off, security off, NAT off (on the extreme), and still got a max of only 3.7mb/s. Either there's a setting I'm not seeing, or I'm starting to think that the WAN port of the express is limited to 3.7mb/s as it was primarly meant to be connected to an internet connection rather than a computer. Anyone have any advice, or do you have a similar setup where you are getting more than 3.7mb/s between an express and an extreme?
