So I went into testing the beta firmware and immediately had issues.  I have 6 cameras and at no one time would all cameras connect to the network at the same time.  If I could get 4 to connect to the network 2 would be down.  I one of the down cameras connected, one of the connected cameras would go down.  The beta firmware seemed to be a little worse.  I also noticed, and this is not specific to the beta firmware, but when using the dlink vs linksys velop, my feeds from my cameras have lighter or washed out images.  I don't know if that means anything.
