Re: RBR850/RBS850 WiFi slow on a 1GIG fiber (getting 90Mbs up/down)
I have the exact same issue with the WAN port speed capped at 100/Full. Setup: AT&T fiber - Arris BGW210-700. WiFi radios disabled RBR850 set to AP mode Working fine, speed tests are blazing fast...
The real problem isn’t the cable. As I was trying to explain, the cat 5E cable that came with the Orbi was hooked up and working fine. The firmware update capped the WAN port speed to 100M/Full. Nothing else changed in the previous working setup except the firmware. I tried everything I’ve read and everything I can think of as an IT tech myself.
I’ve read several other folks in mostly the same boat - firmware updated, and now the speed is capped at 100M. Seems the firmware broke something. Prob something silly like a typo in a line of code. 100 instead of 1000. Most likely an edge scenario where you’re configured a specific way, and that causes a different branch of the installer, and that’s where the problem lies. I don’t know, but it’s certainly an expensive bug since it renders the Orbi useless since my lame AT&T WiFi router is faster than 100m, even at the outer reaches of it’s range.
Try this, disconnect the RBR from the modem.
Factory reset the RBR and let the front LED blink WHITE.
Pull the power cable from behind the RBR for 30 seconds then plug back IN.
Setup from scratch with out it connected to the modem.
When you get to the home screen, connect 1 wired PC to the WAN port of the RBR. Open the networking adapter status window on this PC and check the connection speed seen here. The PC wont get an IP address however we are looking to see if the PCs adapter can see the connect rate on the WAN port. 1000Mpbs should be seen here I hope.
Also check the Show Statistics section on the RBR web page. This will show all connection rates of connected devices on the WAN and LAN ports.
I just took my 8 series off line about a week ago...though mine was in router mode, WAN port connects at 2.5Gb for me with my modem.
