Slow speeds registering on RBR750
I have Xfinity 1.2gbps service with their XB7 gateway. I use the gateway in bridge mode and the Orbi RBR750 as the router with an RBS750 as a satellite. Using the Xfi app I’m registering consistently at 1.3 gbps. I’m not great with this stuff but I can’t seem to figure out why all of the sudden I’m only getting between 600-700 mbps registering at my RBR750. If I hardwire a device to the XB7, I get over 1gbps. If I hardwire the same device to the RBR, I get between 600-700 mbps. The gateway and router are about 5 feet from each other hardwired with a short cable. This is a new issue as of 08/16/21. Before that the speeds were fine. I don’t remember if I had just done a firmware update or anything like that.

- Here’s speed to the modem
Don't use Orbi app to speed test. There is a known problem with the Orbi app and RBRs on board speed test giving inaccurate results on v4 FW. Use a wired PC connected to the RBR and speed test with Ooklas installable speed test app and compare results
- Unfortunately I’ve done that using a pc and Xbox series x to the XB7 gateway wired and got speeds at or above 1 gbps, while those same 2 devices wired to the RBR750 only get 600-700 mbps.
- I have this exact same issue. I’m using CM1000v2 modem and get 1GB speed direct to the modem but when the Orbi is connected both hardwired and WiFi speeds max at 600-700Mbps -
Is the feeling here that this is firmware related rather than hardware.? I’m still just in warranty period so want to get it replaced before it’s too late if there’s not a firmware fix coming.
Factory resets, new cables etc aren’t the fix. Router in access point I doubt is going to be the fix either as I’m using the Netgear modem and Orbi router combo and seeing exactly the same results. Hard to put a specific date on it but seems like this might have started late May early June time. Oddly it only seems to have been getting worse lately. I get the same results with the Orbi built in speed tests and using Ookla app and websites.
