Anyone had problems with a wrt54 running dd-wrt?

Hi all,
A few weeks ago I moved my hotspots from inside the house to the shack because the people I live with thought it was a good idea to always unplug them as "they found the lights annoying". Of course...I have no wifi in my shack so I was using the wifi in my PC to make a "mobile hotspot" for the purposes of getting them online.
The other night I took an old wrt54g that was collecting dust and threw dd-wrt on it. I figured since the hotspots don't need super fast wireless-n, this would do the job. It for the most part has....one ONE of them. My Zumspot setup configured for DMR works fine.
The Jumbospot I have for D-Star....well....apparently, the wifi isn't happy anymore. I started noticing after about 5 minutes that DStar conversations were dropping packets and the reflector kept reconnecting; then at some point it wouldn't reconnect. I tried a different reflector thinking that particular one was having issues...but it still wouldn't link.
Jumping on to the dashboard told me something was wrong....or rather the inability to connect to the dashboard. I had to make 10 attempts before it would load. System load on the configuration was about 1.9 across the board. I tried getting in to SSH, took several tries. Finally log in, try to load top; took 3 minutes for it to appear on the command line to run it.
ACtual CPU usage was at maybe 10%; however, the software interrupts were sky-high. I saw several kworker threads related to the wifi driver.
I'll admit I haven't ruled out a problem with the SDCard. It seems strange that one would work fine with the AP and the other would fail. I will report on my findings after I get another card flashed and swap Pi0Ws around a few more times. But has anyone ever encountered a problem with the RPi just refusing to work on a specific access point? It seemed weird that the Broadcom driver (from what I could tell) would be causing problems since the wrt54g is also broadcom.
