Help Poor Wifi Performance

[ChuckyZ28]

Well I want to start out saying I have 3 Devices; a laptop, a samsung galaxy rugby, and a TF700 all are sitting right next to each other and all getting very different wifi performance.

Internet TWC Road Runner: +/-20Mbps Down, +/-2Mbps Up

Laptop: Speedtest.net 19.53Mbps Down, 1.97Mbps Up
Phone: Speedtest.net 12.89Mbps Down, 2.78Mbps Up
Tablet: Speedtest.net 4.59Mbps Down, 1.83 Mbps Up

As you can see all are very different, I discovered this because I was trying to login to OnLive on my tablet and it stated I was unable to because I had a poor internet connection.

I had problems with a router until I disabled AES encryption and enabled TKIP.

Take the averages of no less than five tests PER DEVICE for each device.

One thing that should have caught your eye is that the uploaded speed is not following the same trend as the download speed, so obviously you have some latency issues, or else traffic issues.

As for the tablet, though, - unless you have a dual band router, which could account for the discrepancy between the phone and tablet, particularly if the phone supports the 5 GHz frequencies, but at this point I doubt it. Is the tablet running they latest and greatest firmware?
