Umm ... guys, as already stated, I'm not working on this any more. I have exactly enough ports for my cat 5 needs now. I already own a swell switch and don't need to buy one. I've concluded that the failing wifi on the new laptop is in the laptop, and is either a bad wifi card or a configuration/OS problem -- and that it's not mine to diagnose. I'm _reading_ this thread and _appreciating_ the suggestions, but I'm not going to do anything about it. Next week I'll take the laptop to Alex's school's IT guy and ask him to diagnose and/or configure it. If it's HW, then back to Fry's. You are free to continue or to drop the thread, as you wish. And again, thanks. -- Lan Barnes SCM Analyst Linux Guy Tcl/Tk Enthusiast Biodiesel Brewer -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
