No response as yet but I can add a little further information. Using the tool www.speedtest.net I conducted Internet speed tests from my MacBook Pro and repeated the test following various environmental and configuration changes.
As stated previously download speeds on the MB/AirPort Extreme n-network where the MP is the only node are consistently around five (5) times slower than an XP Pro laptop on my g-network. So here are the non-numerical results of my tests:
Note the AE is practically line-of-site to the MB, no concrete walls intervening, distance about 15 feet. The USR router is channel 9, the AE is channel 1.
1. Set the AE to n-only (5Ghz): No improvement
2. Set the AE to n-only (2.4GHz) : No improvement
3. Set the AE to g-only : No improvement
4. Switch off my cordless phone (reduce potential interference) : no improvement
5. Switch the MB to the USR wireless g network : downloads improve to the same level as the XP Pro machine.
Conclusion: Apple's hardware, firmware of software implementation of wireless on the AE is seriously flawed.
I noted that ping times in the speedtest were 25% higher via the AE, which has a Gigabit wired connection to the USR via the WAN port and is in Bridge mode.
I found the solution. Purchase NetGear NAS and use it to share iTunes library, stream other media and also use it for Time Machine backups. Works a treat. Cable my apartment using NetGear PowerLine Ethernet over Power adapters. A little pricey but seriously good, consistent performance. Sell Apple Airport Extreme to some poor sap and voila, home networking that works.. for me anyway.
mike sanders3... not helpful in any way... Please take your insults to another forum.
Fatb0y; I have the same issue with my MacBook Pro. If I reboot the AE it is fine for a while, but then things slow down again at some point. That is, if I am using it as a router. I had been using it in bridged mode, but after having dissappointing results with Pogoplug, I thought I would try using the AE for cloud drive sharing.
By any chance, where you using the access restrictions function? I am trying to narrow down the issue. I am sorry to hear that you had to get rid of it, but I completely understand.
