Very slow network speeds on 5GHz network on Orbi RBR50 after months of solid performance
Hey All, Hopefully someone can help me with this. I just started noticing some really slow network speeds on my 5GHz connected network devices a couple weeks ago. This is after several months of ...
Thanks to all who pitched in. Your advice was helpful! I just took a backup of the working config in case I need it in the future. Setting this as resolved now!
Thanks tomschmidt. Just curious, are you getting better then 24Mbps Internet test speeds while connected to the 5Ghz wifi with that firmware version? And did you perform a factory reset after flashing the firmware? I'm getting ready to do this on my end and will report the results back as soon as I am done. I am hoping that the reset will do the trick, and get me back the speeds I lost after flashing to 2.5.1.8.
Update: One factory reset (and about 4 hours of reconfiguring from scratch) and everything is working as expected again - with theV2.5.1.16 firmware!
I am now getting the expected Internet speeds when connected to 5GHz wifi. And I can see on my wifi analyzer that the devices are all connecting to the router and satellite at 5GHz with a 80mhz wide channel. Earlier when this all went down, I noticed that the 5GHz devices were only connecting with only a 20Mhz wide channel. Now they are all connecting again with a 80mhz wide channel. I believe that was the culprit, but I cannot 100% prove it to be the case.
When everything was busted, I went around the house with my analyzer and saw that the 5GHz networks were advertised as "A54 - 20 MHz" channels. The 2.4 GHz networks were showing up as "g54 - 20MHz" channels. After the factory reset, my 5GHz networks are now listed as "AC867 - 80 MHz" wide channels. I believe that the 20MHz narrow channel was essentially restricting throughput on my 5GHz network to similar speeds as the 2.4 GHz network.
Anyway, what have I learned through all this?
1) Do NOT update your firmware on these Orbis unless absolutely necessary.
2) Have a good wifi analyzer app for your phone handy and take some metrics BEFORE you update the firmware and AFTER you update the firmware so you can compare.
3) If you do have to update the firmware, best to just factory reset them and set up from scratch afterwards.
4) Again.... Do you really need to update the firmware? Is it worth it? Sleep on it before doing so...
I hope my notes here in this forum help some folks!
