Yup QoS is disabled but wifi WMM is enabled (I gues that is QoS for wifi) but I see the same issue over LAN too.
My fiber ONT is in bridge mode and the mesh is in router mode yes.
Will see if I can come up with further stuff to try, in the mean time just hope for a firmware fix.
Gist of the issue is that the RBK50 exhibits slow upload speeds on LAN or wifi *after* a reboot.
If I make a modification to the WAN settings (like change the MTU setting a little bit) and apply the upload speeds are restored to my 300 mbps up/down levels, but then again if I reboot the system...
Yeah I don't use password managers nor browser based either.
I've just got myself signed up with firefox monitor service.
For important logins I use unique passwords and 2fa with backup recovery codes if available.
That is a nice link posted about password hashing.
