Significant Drop in download speed cbr750
CBR750 — Orbi WiFi 6 DOCSIS 3.1 Mesh WiFi Cable Modem Router Firmware version V4.6.3.6 App version 2.11.0.11 In last two days, my Download speed dropped from between 1200-1400 to 500-600. Had t...
I am still frustrated with this situation.Yes I can pull 900 + hardwired but I have a significant dropoff in speed on wireless that was not the case before the firmware update. I also see that my wireless devices are now ignoring the satellite and staying attahed to the CBR750. Only one or two devices connect to the satellite, the ones right next to it, while before this update I usually had 10+ devices connected. I am on Comcast and see that the Cox folks got a new version pushed to them. I hope Netgear is working with Comcast also for a quick resolution to these issues.
Same exact issue over here what the hell, making me instantly regret firmware update.
At least im not the only one...
Factory reset the CBR modem and power it off, I would power OFF the CBR modem and RBS for 5 minutes by pulling the paper adapters from the wall outlets. Power ON the CBR modem and let it sync. Walk thru the setup wizard again using a wired PC and a web browser.
Speed test the wired connection first, then wireless.
Do not speed test with the CBR built in speed test app or Orbi app. Use Ooklas installable speed test app on the PC or your wireless devices.
Turn ON the RBS after testing the CBR.
FURRYe38 Appreciate your info. This is pretty much what tech support had me do. I will try it again on a quiet day.
This is way to much to ask a regular user to do. I have recomended this product to others who now have the same issues.
Netgear should allow a rollback or more ideally a update to Comcast to fix the issues.
This update should have been sent out to a beta group to test before rolling it out to everyone.
well, there is hope. My hardwired speeds are back to normal, and wireless speed is great. Don't use Netgear web interface or mobile app to check speeds (inaccurate). Use Speedtest.net or the corresponding Speedtest app. It gives much better speed readings.
- St james, what did you do to fix this. I havent tried speed testing wired to the modem yet. Did try a factory reset to no change in speed. Havent powered off or unplugged router yet. If this issue has effected so many ppl with comcast yet isnt orbi addressing this with a fix to this last broken firmware...
I didn't do anything.
Just like everyone I was very frustrated, called Xfinity (and let me tell you, they will do anything possible NOT to come and check your line), and finally I just sat back. I did get a call from Xfinity which said that they identified some issue with the internet, and that they had resolved it.
I had 600 Mbps at first, but it went up to 950Mpbs-1000Mbps. I made sure my satellite had a good backhaul, and after that, most everything was just fine.
I really think it is some issue with Xfinity's coax line. And as I said, if you use Netgear's tools to check your speed, they will be innacurate. Just use Speedtest.net or the app, and you will get better (and more accurate) speed readings.
I only use the coax line for internet, so I found the splitter, and made sure that the line coming from outside only was connected to only ONE device, my cable modem. All the other connections to other rooms in my house were disconnected. Doing that did improve my signal by a factor of two according to Netgear's diagnostics (it went from an acceptable -8.0 dBmV to a low of -3.7 dBmV on some channels). The signal though, still fluctuates to unnaceptable levels some days above -8.0 dBmV, and I don't even get a signal from channels 31 and 32.
Unfortunately, I cannot assure you that what I did made the difference, but I can tell you that the signal was weaker in my case before I stopped it from being split.
