It's loving ridiculous. I've been getting 35.5kbps for like a week now. When it's working the way it should be, I get no more than 110kbps. Even on uncapped downloads.
Meanwhile at my other house I'm getting 256kbps wireless on Comcast. Uncapped downloads will give me upwards of 1Mbps.
Internet games seem to work fine, however I have noticed that my average ping has gone up, further lowering my server selection.
