Thanks guys!!!!!
I turned off the Buffalo and was able to connect directly to the E2500.
I now have the Buffalo on as a client and can connect with no issues to either device at will. I will keep it running this way for a day or two to see if it's stable...
My flavor of DD-WRT does not have Repeater bridge, just Client, Client Bridge, Ap, Adhoc, WDS Station and WDS AP. I will try moving to Client Bridge later this week if things seem stable and I have more time to play with it.
Thanks again for all the help,
Mike
