Can't connect more than one computer to wireless network at a time

[rjseals]

To start off, let me tell you that I just got cable internet 2 days ago. Last year while at school, I had the same ISP for cable internet as I do now. Same setup and all.

I have my Toshiba cable modem plugged into my wireless SMC7004vwbr router. I have 1 PC that is CAT5'ved from the router to the PC. I have 2 laptops which are wireless 802.11b. As I stated before, I had this same setup with the same router and same cable company last year. I can rule out the cable company, its something wrong with my router or machines.

Basically if I turn on one machine (doesn't matter which one) it connects right away and will work for hours without any problems but as soon as I turn on another machine they get really slow then lose their connections completely until I reset the router. It doesnt matter what order the I turn them on in. For instance, all of them will work fine by themselves but like I said as soon as another one connects to the router they lose everything. Im pretty sure its not a virus because if it was then the machine with the virus wouldnt work right by itself.

They all have window's XP on them and 3 months ago before I moved they were working fine.

Any ideas?

Thanks for your time.

It sounds as if you have NAT and DHCP turned off on the router.

Also, if your router supports MAC cloning, you should use this feature to clone the MAC address of one of your workstations to the router.
