Linksys wireless b router locks up everyday

how do you have the routers hooked up?  You sould be using the uplink port on the wired router to one of the regular ports on the wireless router.  Also, make sure that only one router is acting as a dhcp host.  (the DHCP thing sounds like the problem)

Another solution might be to use a crossover cable.  You can buy them or you can make one yourself.  It will allow you to connect to a regular port on the wireless and a regular port on the wired router.  

good luck

I had a similar problem with my Linksys. It kept freezing up all the time and I had to reboot it to get it working. So I replaced it with a DLink.

Then I had a problem with the DLink. where my PC kept losing it's DNS information, so it seemed as if the new router wasn't working. Rebooting the router would fix it temporarily. But the fix was to manually configure the router with my DNS servers. It seemed that for some reason, using DHCP on the router for DNS info, and then my PC using DHCP to get DNS servers from the router, wasn't very stable. Since I manually configured my ISP's DNS servers into the router, it's been rock-solid.

How do you set up a static address on the router(linksys) and maintain DHCP for users?

It depends on the firmware version.  They are all different.  I think you should upgrade to the newest firmware version.  I know someone who was having the same problem.  A firmware upgrade solved their problem.  You can download the latest version by loging on to your router administration utility.  My upgrage button is in the system menu, but they are all different.

Good luck
