[PLUG] (Semi-OT:) Linksys router messes up my LAN

[Anthony Schlemmer]

I have one coworker that has a Linksys wireless router at home and he 
hasn't complained of any problems. I don't have a wireless router but I 
do own one of Linksys's newer 802.11g access points which apparently 
runs some version of Linux on a MIPS processor from what I've heard 
second-hand. 

I also heard that Linksys came clean and made their Linux source code 
available as there was a big stink about Linksys not releasing the 
source code over on /. not too long ago.
