Orbi WiFi speeds drop low until I reboot the router
I have the following Orbi mesh router with 2 satellites running the latest firmware v.188.8.131.52:
Netgear Orbi Mesh Router RBK53S-100NAS (router + 2 satellites)
Router Product Model: RBR50v2
This is NOT a wifi6 router
Every so often (once a week) my wifi speeds in all the wireless devices gets really low (~ 30 Mbps). Then I unplug and plug back the router. After that, I get back my normal wireless speeds ~ 300 Mbps. Until a few days later when speeds drop down again and I have to repeat the process. I am about to retire this Orbi and purchase a new mesh router from another vendor (no more Netgear - this Orbi has been nothing but troubles) with new WiFi6 capabilities.
Does anyone have any suggestions on how to solve this annoying problem? I am also not so happy for getting ~ 300 Mbps on wifi when my internet capabilities are 600 Mpbs (verified with wired connection).
