With Fedora 18 running, and sitting about 10 feet from a Linksys WAP54G access point I get "one bar" on the Gnome icon... if I double the distance, I start losing the connection. > > If I reboot to Fedora 17, I get three/four bars at 10feet, etc. > > I've checked the internal antenna cables, and made sure that each OS is running the most up to date kernels.

Regardless of the number of bars, is the download speed similar or very different under the two versions? (I ask because there was some talk earlier about the number of bars becoming a more accurate assessment -- I don't know if this has been implemented).
