This also happened to me just now during a very important meeting. It is imperative, to at least update the firmware, so that the router is quickly able to restart/reboot when such disconnection issues occur (if they occur at all), so I can be back online quickly, without the need for a lengthy manual intervention that I cannot afford!!
Please make sure that the router reconnects by itself when it looses connection.
For the firmware/update developers: this might help in figuring it out…
Thanks for all your efforts in this regard,
