I'm having problems with our SBG6782. Need to reboot manually at least twice a day.
Culprit appears to be the 2.4 GHz network. Have tried Band Steering, but that takes down the whole network.
Both Internet connectivity and LAN affected... eg. wireless printer will not work.
Have changed channels, messed with all settings. Appears to be a hardware issue.
We're a Mac household, all devices running El Capitan.
Thanks for your help.
