ORBI Mesh upload getting slower after a week

[Danielworks]

Hi there,

My ORBI Mesh system (router + 2 satellites) has a wired problem.

The router upload speed only reach 80MBps when the fibre is capable for 400MBps.

I've done the search across forums, upgraded fireware to latest v2.5.1.16, ran a factory reset, and get full speed of 400Mbp+ on both up/down stream.

However, after a week, when I ran a speed test again, the up stream was down to 80Mbps, and nomal reboot won't fix this issue unless I do a factory reset.

The speed test was done through router's speedtest so there is no WIFI/cable speed issue.

This is getting annoying as I don't want to reset my router every week, is there any one has a solution about this issue?

Cheers

Who is your ISP and what equipment did they provide?
What is the current firmware on your Orbi device?
What device is your Orbi router connected to?

Did you reboot your ISP modem/router, before starting the Orbi router install?
Have you changed the network cable connected from the ISP device to your Orbi router? If cat5, you need to change to at least cat5e
Disable Circle, Armor, Daisy Chaining, Fast Roaming, IPv6 and uncheck 20/40Mhz Coexistence.
Enable WMM, Implicit BeamForming, Mu-MIMO
Set Short preamble mode. Save settings, reboot Orbi.
