Let me see if I can do this situation justice. Have a very functional wireless network running through the house, centered around a WRT54G router and a WAP54G access point serving as a repeater. In the process of adding the Linksys Media Extender to my entertainment center. Everything I've read recommended running that on 802.11a, so I've purchased a WRT55AG that I'd just like to add to the existing infrastructure (have disabled the 2.4ghz radio). Problem is, I can connect the WRT54G and the WRT55AG together to the extent where I can get internet through the WRT55AG, but I'm unable to access any of the computer resources attached to the WRT54G. I'm actually not able to ping anything cross-router. Any ideas on what the problem is? The WRT55AG is a v1, I believe.
