That seems to validate what Brandon has been seeing in my logs and/or the diagnostics/traces that have been done.

Thank you for finding that - the search function on their forums is horrible - I should have been able to find that before I posted a thread about the same topic that got zero (useful) responses.

I don't think I'm going to waste any more time with this - probably going to go get my WRT54GS and set it up as the main internet router and use the 610N as an internal router.
