Hi Guys,

I'm having lots of disconnects from my ac66U being used as a bridge. I'm no network engineer, and don't understand 99% of the logs that I see, although the router looks quite busy doing things. does any kind soul have any idea what is happening and how i can fix it?

Really? Pastebin.com please.

RT-AC66U latest builds have problems with Repeater Mode and probably Bridge Mode also, 380.56 will fix it.

Please report this to: networking_support@asus.com so they can fix it.
