I work as a developer for a company that has to set up a lot of wireless networks to work with handhelds like PDAs and Palm devices. We have nothing but trouble with the clients who have Linksys equipment in general. With zero hyperbole, every single client who calls with a networking issue has either Linksys or D-Link hardware.
While suggesting industrial Symbol routers isn't gonna fly, I have a Netgear router at home and it is the bomb. This is after watching a D-Link and then a Linksys kick the bucket less than 6 months after purchase. The Netgear is now 2 years old and has yet to cause a problem.
