I'm with Doug, sounds like hardware on its way out. My 2820 also failed on me, started giving very high latency when routing.

So much for my theory of spending more money = longer life hardware frown

I'm not back to a two box solution, with my old Thomson TG585n as a modem (as it was useless as a router/AP) and an ASUS RT-N66U doing the routing with Tomato.

Which reminds me, must start a thread discussing my woes with Tomato frown
