I have noticed that my iPod Touch is twice as fast for downloads and four times faster for upload than my Droid. (I used the speedtest.net app for both)
I have already used WiFi Analyzer to find the best availabe channel, updated the firmware on my Linksys WAP54G access point, and tried turning the WPA security off. I also tried "forgetting" my network and configured it manually by entering the network name and password through the Add WiFi Network tool. I even switched my access point from wireless G to B with no improvement.
Originally the iPod Touch was four times faster for downloads too but by changing the WiFi channel after using WiFi Analyzer I doubled my Droid's download speed. That app is really amazing.
On my Droid I get 4.4 Mbps down and 1 Mbps up. On the iPod Touch I get 8.5 and 4.2. My laptop gets 13.7 and 4.2 and I have Comcast cable internet.
Is there anything else I can try to change to improve the WiFi speed of my Doid?
