R6700v3 New Firmware Slow Speeds
Hi. I have a Netgear 6700v3 connected to a Netgear CM600 modem. I pay for 300Mbps download and 30Mbps upload. I usually get 300-340Mbps download during speed tests. I noticed recently that I was...
Myself and a friend had the same issue. I noticed slow download speeds the other day, ran a couple speed tests and confirmed something was up. We both have gigabit FIOS and I could not get more than 200-250Mbps up and down. I tried factory resets etc and nothing worked. Both speedtest.net and Verizon’s speed test to their network which consistently gets high 800s to 900s was getting sub 300. Reset my ONT, plugged into ONT directly and the speeds were better. Eventually I tried rolling back from 1.0.4 to 1.0.3 and the speeds were fixed!
I rolled back and turned auto update off. Really annoying the new firmware was causing this issue. Wasted a day or two troubleshooting and even calling Verizon. Hope it gets fixed soon.
Also, this was on the r6400v2, not the v3!! So it effected the v2 as well.

Classic memory leak in firmware, do they test this stuff ? Truned off all features I could, even 5G radio, it helps but still have to reboot every day to get performance back. Also down graded version to V1.0.3.66_10.0.50 from current 1.0.4.78_10.0.55 it helped a little but this problem has been in the last two release time to fix this passed, who ever is testing and coding need more training.
Trying V1.0.2.52_1.0.39 firware now, yes I factory reset after loading new fireware.
This memory leak seems related to the speed of the connection between the router and modem, wonder if back pressure/flow control from the router to the modem is working ? My speculation is when the router is flooded with data the buffers in the router's memory doesn't recover and some memory is lost. Over time this causes the router to slow down and a reboot is a way to recover the lost memory.

HIghly doubtful. Netgear seems to have forgotten what good tested firmware is. Same issues release after release. Only relief for folks is to install back level firmware. Not the direction most folks want to go, but seems the only solution for many. From what I see, there seems to be little or no oversite of firmware being shipped. If there was QA then ongoing bugs would have been fixed or the firmware would not be released. Reason I went elsewhere for my network equipment. Network now just works. No issues, never a reboot except for firmware update. Have never pushed the reset button after initial install.
- Where can I find the older firmware and directions on how to roll it back? I’m a tech noob ¯\_(ツ)_/¯

Just tried newest V1.0.4.82_10.0.57 no improvement
In picture before long ping times just after reboot short ping times for internet traffic
first 4 lines are local with 2nd line wireless local
time frame about 8 hours
