Problem: Getting < 10 Mbps downstream via Speedtest.net with Bluetooth enabled, < 15 Mbps with Bluetooth disabled. Upstream is actually faster consistently, a bit over 10 Mbps.
It's very inconsistent. In the past few hours I've testing I topped 20 Mbps, once. Then just the past few minutes I got 1.5 Mbps (with Bluetooth disabled).

Causes Eliminated:
- ISP. PC connected via ethernet gets 70 Mbps
- Router. Replaced a Buffalo router running DD-WRT with a Asus router running Tomato.
- Wifi: iPhone on the same network gets over 20 Mbps (if it's in range of a MBA with Bluetooth on however, that speed is greatly reduced)
- Computer: My wife has a Macbook Air that has the exact same issue
- Outdated OS: We're both on Mountain Lion but had this issue on Lion as well
- General Wifi issues: My link speed in the menu shows 72 and the Network Utility link speed shows 144 Mbit/s
Fixes Attempted:
- As mentioned above, disabling Bluetooth increases the speed by ~5 Mbps. Unfortunately this makes all of our Bluetooth keyboards and mice useless. However if I was able to disable Bluetooth and get > 15 Mbps I'd be at least a bit happier
- Went to Network -> Set Service Order and put Wi-Fi above Bluetooth. This actually increased speeds from 1 Mbps (lol) to 10.
- Plugged in manual Google DNS
- Replaced wireless router (mentioned above)
- Changed wireless channel several times
- Forced N only mode
- Disabled wireless security
- Moved around to different locations including right next to the router
