Got my router a while ago and somehow just noticed its speeds are pretty bad. Does anyone out there actually get 802.11AC full speeds? I get 72mbps for the first split second using 2 different speed tests, then 72 drops to an average of about 12-24mbps for the duration of the test. If anyone has a working configuration could you share that?

Also I hope i posted this to the right area. Still new and forums are not my forte.

Probably better to post in Broadcom forum. Also that build is ancient, could not hurt to update I think.
