Speeds decreased in latest firmware update ( R6400v2 )
Re: Speeds decreased in latest firmware update ( R6400v2 )
My speed (wired and wireless) degraded from 400 Mbps to 150 Mbps after I "upgraded" firmware from 220.127.116.11_10.0.50 to 18.104.22.168_10.0.55. Very frustrating. It sounds like I am experiencing the exact problem that you are.
Then I replaced this Netgear R6700 v3 with a lost cost TP-Link Archer AC1750. I'm back to 400 Mbps.
Also, I have seen several others on this Netgear Community who have this same problem.
I've had it with Netgear!
