R6400v2 creating bottleneck
just had comcast out and we were trying to troubleshoot my connection. I pay for 1200 down and suddenly I was only getting 200. I had did some troubleshooting factory reset of router and restarting modem etc. I assumed it was in the signal and so did Comcast. We ended up replacing some connectors and cabling etc. Then we were still getting the same speeds. We ended up bypassing the router and plugging straight in to the modem. Boom 900+ down. I did a factory reset on the router again in an effort to correct the issue, but the problem is persisting. I previously was getting 900+ with the same setup.
Router firmware is V1.0.4.120_10.0.91
Cable Modem is Motorola MB 8611
This is over a wired connection, however the wifi is only at about 50% of what I normally get as well
After doing quite a bit of reading in this forum of old threads the consensus was to roll back to 1.0.2.52_1.0.39
all the firmwares are found here https://www.netgear.com/support/product/r6400v2.aspx#download
It did help to get much faster speeds for me also tried the fresh tomato firmware but it didnt seem to help me but it did completely wipe all my settings and I was 100% sure nothing was carried over in any way. If you want to try it out it can be found here. https://freshtomato.org/downloads/freshtomato-arm/2020/2020.2/Netgear%20R-series%20initial%20files/

- cscott1GuideYeah I have the same service with Xfinity and the same issue with the 6400v2 downgraded the firmware which helped get more speed but ultimately bought a new router the Rax50 to keep up with the speeds much happier now.
- danheinz1126AspirantHave you seen why? Everything I saw showed it should be supports and it did work for awhile.
have you tried enabling ipv6?
What website are you using for testing?
Make sure qos, access control, traffic monitoring, and parental controls are all disabled. Then reboot the device and test.
- danheinz1126AspirantIpv6 was disabled I set it to Auto detect and it chose DHCP. Everything under qos is disabled except for WMM tab. All other settings are disabled
- Did it help?
Did you try a factory reset and new install? (don't use a backup)
