Guest network drops

[BWong]

Hi,
I'm having a small problem. I bought this router because I like to game and this is capable of running guest networks. My main network uses WPA-2 security but I need to have a guest network running WEP to allow my Nintendo DS lite to connect. This is where I'm having my problem.

I am able to connect with the Nintendo, but as soon as I find a match and start playing I get dropped. I've tried all of Nintendo's fixes (manual IP, disabling firewall, placing the DS into a DMZ, port forwarding, etc) and I am able to complete around 1 out of 4 of my matches.

Right out of the box everything worked great, I was running the .178 firmware then. I decided to upgrade and then this started happening. I've cleared the NVRAM correctly and even went back to .178 with no success.

I'm sure it's a guest network problem because if I place my main network into WEP mode I'm able to connect and play for hours on end. As soon as I switch it back and enable the guest network I get drops all over the place.

Any ideas?

Do you see any clues in your router log?

It looks like it's just releasing my IP.
