i recently bought a trendnet 811dru router and i haven't had a stable connection yet. i try using the "troubleshoot problems" and i get errors with my default gateway and such. if i am connected to the router, its reallllyyyy slow and most of the time limited with that yellow triangle. right now im using a tplink wn8000nd wireless adapter, and it works perfectly fine with my old router. and yes i upgraded the firmware, and did plenty of resets
