Basically heres what trying to achieve.

Internet---->modem---->encrypted wireless network(ap1)----->open wireless network(ap2)
(acces point 1+2)

I've been successful up until the last part of it. Everything is fine up to (ap1) the problem starts when trying to get on the internet on (ap2). When you first open the internet browser you are able to access the internet but after a few moments you are unable to get on the internet anymore unless you power cycle (ap2) and then the whole process starts over again. I know it is probably just a setting that I'm missing but any help would be appreciated.

What I'm using

Cable co.--->motorola surfboard 5100 (provided by cable co.)---->linksys wrt54g--->
