Unstable router

[meester]

Any tips for debugging? My router is crashing when streaming video (iplayer) over wifi. It's a Buffalo wzr-ag300nh.

I have to power cycle for it to work again. I am running the latest (v1.49) firmware.

When you say crashing are you saying that it's no longer able to route traffic? Do wired clients hooked up to it still work?
