AC1750 : spotty connectivity
I have a AC1750 Wi-Fi Range Extender that's had spotty (but liveable) performance for quite some time but lately it's becoming much more frustrating. My scenario is that devices that are connected to the extender periodically lose internet connectivity. When this happens, they are still connected to the extender (I can verify this also in the extender's admin screens) but just can not access the internet. If I restart the extender, internet connectivity comes back again for a random amount of time before it's lost again. (Sometimes it's a few minutes, sometimes an hour, etc).
Internet conectivity is otherwise fine (all devices access it perfectly through the wifi on my router if the extender is shut down). [Signal strength is another matter, thus the need for an extender]
Firmware on the extender seems to be the latest. Is the next best step to just reset the extender and start setup again from scratch?
Oh, the SSID for the "extended" network is the same as that on the router; could that be an issue?
Thanks for anyone who can offer guidance!
