Thought I would give you the results of what I tried.
I ended up using the WRT54G router. I couldn't flash the dd-wrt firmware on it since it was a v6.
I connected 7 WAP54G access points with static IP's wirelessly to the router. I was able to ping all 7 AP's and the signal strength was fairly good throughout the office.
The problem I am having is after 1 week of working I am losing AP's and I can't reconnect to them. Restarting the modem, router, and AP isn't helping. I even brought the AP's back to the router and hardwired them to check the settings and everything is fine. I can actually connect wirelessly to them when they are in the same room as the router.
The thing that makes it difficult is that the AP's have to go in specific locations. I even tried upgrading the router to the WRT54GX4 only to find out the WAP54G doesn't work wirelessly with any other router besides the WRT54G.
I need to know if I should just replace the whole setup with a Pre-N setup or is there something I can add to the existing setup to strengthen the signal to the AP's? I don't think I need much since it was working before, but I may be wrong.
Also is there a reason why the AP's were working and then some dropped off?
Thanks again for all your help
