I find that a second reboot makes is so the update doesn't take 2 to 3 hours to work well. Typically in the 2-3 hours after my last 3 firmware updates I had no Internet access. The second reboot dispenses with the delay.
Probably something else, but there is certainly no harm in that sort of move.
I step in to add yet another wrinkle. In the past, depending on the firmware version, Netgear has also occasionally specified a reboot before updating the firmware.
If I saw the above happening, and a failure to connect post flash, I would first see if a factory reset fixed it. (First backup the current settings.) If not I would also restart the network in the specified order.
As this is a router, there is probably a modem sitting in front of it. You need to get the devices to forget any inherited settings. Among other things, that means rebooting the network.
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
That didn't help. The R7800 is crashing WLAN every couple minutes with the v1.0.2.80 even if it is not connectet to anything and even when you do a factory reset before and after updating firmware.
Note that starting with this firmware release (V1.0.2.82), the following features are no longer supported: ReadySHARE Vault, OpenDNS (Live Parental Controls), remote GUI access, and WPS PIN function. If you want to continue using these features, do not update the firmware.
