Orbi Lan connection issues
Hi! My orbi system (RBR50 with 2 RBS50) has been great, it provides strong and reliable wifi everywhere but recently a major bug has been troubling me. The system will randomly drop LAN communicat...
Yes, seems like a odd one...
Might update FW and see if anything changes. Not sure if it will.
Alright. I have caught it in action. I have 2 satellites and 1 router, the upstairs satellite and the downstairs satellite.
Troublesome device: Switchs from Upstairs satellite to the main orbi router. Now downstairs satellite cannot ping or access the device.
Now here's the strange part. I reboot the upstairs satellite, everything recovers.
:scratches head:
"Switchs"?
This a LAN switch? If so, What is the Mfr and model# of the ethernet switch in the configuration?
- No no, as in the device moved it’s wifi connection from the “upstairs” satellite to the main router. I could see the device changing the connected access point bssid in its logs right before it couldn’t communicate with devices on the “downstairs” satellite.
As I said before, a reboot of the “upstairs” satellite fixes it, which I find strange. What is this device?
- esp8266 running Tasmota but it can be any device like an iPad.
Are there any 'recommended' settings for the orbi? All possible i could have a setting off that's supposed to be on. I have a screenshot attached.
I would uncheck the 20/40Mhz Coexistence box, check enable Beamforming and MIMO as well. Apply the change and after that, I'd reboot the RBR and RBS.
- Unfortunately changing those settings had a negative effect, it made the network break down more often throughout the day.
Onto another idea I suppose, but we are running out of those. - But the release notes don’t say anything about fixing this issue? It’s just the dns thing
- Update - Changing the RTS/CTS to 500 has greatly improved everything. Once I have done that everything has been rock solid.
However, after I added ~40 ip reservations the network broke down. I removed most of them but kept 17 and the network has gone back to being rock solid (so far)
I will start slowly adding reservations to see what the limit is, it’s quite a strange issue.
When the devices IP is set on the device itself, out of the dchp range, the network is still stable. I have tested this with ~20 devices and the network is stable, it’s just when I add those reservations on the router itself.
I wonder if I should try using adguard home as my dchp server. What do you think?
I will continue investigating. Was the CTS value 2347 before you changed to 500?
Possible there maybe a reservation limit. I've not tried that though I don't have that many devices.
Whats your IP address pool range on the RBR? Default? You might try setting 192.168.1.100 to .200. Then use this pool size for any IP address reservations. On either side of this pool you can use for STATIC IPs that are set ON devices. You might move any devices that can use a static IP address configuration to this area. Most cameras, NAS, Printers, controllers, etc that doesn't need much router management, set a static instead of a reservation.
Yes CTS was at 2347 before (default)
My ip address DCHP starts at .100 so if i need to set a static ip on device i can use an ip below that. The reservations shouldnt be causing conflicts due to them being set below 100 and not the same as another device.
Try moving more devices to the Static IP address side of things...Free up some DHCP pool side addresses...
