My 4's Wi-Fi is slower than 3GS, is yours?

I've got an Airport Extreme Gigabit N router and when I look at the Wireless Clients page on the AirPort utility, it shows that the iPhone 4 is connected at 39 Mbps and the iPhone 3GS is connected at 54 Mbps. My other devices... MacBook Pro, MacBook and two AppleTVs say 130 Mbps.

Under type it shows iPhone 4 as 802.11b/g/n and iPhone 3GS as 802.11b/g.

Can anyone confirm better than 39 Mbps for iPhone 4? Is this to be expected?

Depending on how you set up your AirPort Extreme, your iPhone 4 may not be connecting at N speeds. Furthermore, there are dozens of reasons why your network might run into a bottle neck with your iPhone 4.

I have a similar configuration, and both my iPad 3G and iPhone 4 are running at 54 Mbps. My MBP is running at 103 Mbps (but it's a bit far away from the router). My AppleTV runs through an ethernet, so no speed issues there. My old iPhone 3GS (old...LOL) ran at 54 also.

On my Airport Express I show the same rates you describe. Nothing I do changes the 39 on the iPhone 4. The iPhone 3gs, its rate is 54 and my Apple TV is 130 along with my MacBook.

On the Airport Express, I have 802.11n(802.11b/g compatible).

I'm Sorry, I have an Airport Extreme not an Express!!

I also found if I select 802.11 g only, then the iphone 4 rate is 54.

You can select this option on the Airport Extreme by holding down the option key then select the Radio Mode.

Mine is stuck at 39Mbps too if I select Wireless-n

I tested it again after upgrading to Airport Extreme Firmware 7.5.2 (just released), it now show 65MBps =)

Speedtest app shows 27Mbps download speed too, so I guess this problem have been fixed now. I can't tell whether the Airport firmware fixed it, or the numerous preceding iOS upgrades
