RBR50/RBS50 Slow Wireless Download Speeds

[simmy93]

I am currently experiencing download speed issues when on the WiFi for my Orbi RBR50/RBS50 mesh system. When on a wired connection I am getting download speeds of 900+ Mbps as opposed to when I am on WiFi I am only getting 10% of that speed at 90+ Mbps. I have updated to the latest firmware V2.7.5.4 and have also changed the wireless settings as per the below screenshot. Does anyone else have any idea as to why it is dropping the speeds so dramatically?

It would help to have more detail about how each of those speed measurements were collected.

By any chance, was the 'wired' speed measurement recorded by a device connected directly to the Internet Service Provider (ISP) device?  (would be useful to know the brand/model number of the ISP device)

At first glance, this appears to be a situation where the ISP and Orbi router have negotiated a speed of 100M/Full.  The electronics built into the physical Ethernet modules on computers, switches, modems, routers, etc. query each other and negotiate the highest speed that they both support:

https://en.wikipedia.org/wiki/Autonegotiation 

The Orbi web interface, Advanced Tab home page provides a method to view the speed that the Orbi router and ISP device have negotiated by clicking on the Blue Box Show Statistics.

This  often happens when "something is wrong" with the Ethernet link between ISP and router. If even one wire fails to make adequate contact or has a physical defect, it will be impossible to negotiate a gigabit connection.  There is overhead in Ethernet communication,so the highest possible speed to achieve is about 92M/bps.  If the reported speed was anything over 100M/bps (even 101), then the negotiated speed would have to be gigabit.  92 just "screams out"  wiring problem.

p.s. It is unusual to disable the SSID broadcast on the 2.4G frequency band.  This will make it very difficult to connect new devices to the system if they support only 2.4G WiFi.

Thank you for your information, I think you were right in saying that it was a connection issue between the Orbi and the modem/router. I changed out the cable and it appears to have fixed the issue.
