wifi is congested.  not sure if it drops on all devices.  router is updated.

Does this happen with all wifi devices in your house? If so, try a firmware update on the router. If not, try updating the drivers/firmware on the device experiencing the wifi drops. WiFi channel interference could also be an issue too, there's are apps to look at channel utilization that can give you a clue on that.

hello - my router is up to date and generally work great however it must be reset at least once per day and occasionally the wifi will disappear for a minute before returning.  Any ideas on why speed degrades forcing a reset?
