WRT54GS Wired/Wireless Crash: Unintentional Hard Reset

Question

Okay here's my issue:
I have four computers  that connect via wireless through this device.  Including my xbox360
I have another computer that connects  through the wired connection.
Everything works fine when security is down.
Not liking weps and how easy it is to crack and not wishing to expose my shared folders containing naked pictures of myself to an unsecured network I've decided to have WPA2 as my security key. Anyways setting everything up was a piece of cake, Until.....
My wired connection dropped.
When I started getting into mac address and setting rules about how I wanted my network set up, and WPA security the router just doesn't like the wired connection.
I checked all the ip's and they are connected to the router with different ip's so that is good.  And everything is obtaining automatically. Well i set it to automatic and even manually set it. The wireless works fine.
However on the wired connection locks the router up some of the lights turn off and the router turns back on.
This is obviously a firm ware issue?
Hitting the reset with no security on, I have no problems.
 Aside from no security.

Answer 1

Just an update turned out half the problem was my mistake the other half the problem was linksys
i filled out all feilds in access restriction - edit list of pcs
The stupid grey bars i did not realized symbolized an OR statement meaning that
fill the top section or middle section or the bottom section but don't fill it all out.
When I realized that you only fill one section out and click save everything started working.
DUH!
Well I am not 100% at fault on that one linksys should have made it maybe a little user friendly seeing this ip stuff is pretty much plug and play.
