For the speed test I used a simple Trendnet 54Mbps wireless adapter with a Linksys router loaded with dd-wrt (but that shouldn't matter)
This is the confusing part. How come I get these speeds http://i.imgur.com/fUXpr.jpg (about 17Mbps avg) with my laptop, but I get these speeds http://i.imgur.com/MAOgM.jpg (from 4-8 Mbps) with my desktop? Both used the same wireless adapter and were in the same location for testing.
Other notes: My desktop is freshly reloaded. Great, normal speeds when connected via wire.
