With careful antenna placement and use of 'iwconfig wlan0 rate 2M' I have a nice reliable connection. Thanks for the advice on lowering the rate. Does anyone think I would be better off with a 15 foot antenna extension cable and a PCI adapter than what I have now which is a USB adapter on the end of a 15 foot USB cable? I know antenna cables are lossy. - Grant -- gentoo-user@lists.gentoo.org mailing list
