RBR50 performance degradation after 2.5.0.38 firmware update
Hi everyone, Updating my Orbi RBR50 router and RBS50 satellites to the latest firmware release package (2.5.0.38) seems to have resulted in a significant deterioration of my network's performance...
So... after reverting my RBR50 and RBS50s to firmware 2.3.5.30, which Netgear considers the last stable release, the network slowdown that came out of nowhere is gone. However, this doesn't cure the random spikes in latency that were driving me absolutely spare. After receiving no meaningful assistance from Netgear's dev team, I've opted to just broom my Orbi setup and replaced it with a more reliable mesh system from another manufacturer. Specifically, the Asus ROG Rapture GT-AX11000 WiFi 6 triple-band system. It's proving to be much more stable than the Orbi was and thus far has offered slightly better performance, though it's about 1 1/2 times the size and looks like a futuristic take on Stonehenge.
Tried a mitigation step suggested by Orbi-Roc involving disabling daisy-chain topology, and it did produce a modest improvement in the network speed of clients connected to the Orbi running 2.5.0.38. Not enough to restore normal performance, but enough to cut the losses from over 100Mbps to around 50Mbps.
Glad it improved things a bit MacrossMike .
My understanding is that an avalanche of DoS Attacks can bring a network to a crawl.
The demand placed on a network can also have a drastic impact on speed. From your observations, you were able to tell if the speed deterioration is constant or sporadic (perhaps in tandem with the data demands placed on the network or the number of data-hungry devices connected to it.)
Keep us posted. Good luck!
