Wifi not working (via extender) on Laptop even with stable internet
I have an Acrher AC 1200 router and I also have an AC 1750 extender. I have placed the extender a feet or two away from the router and the signal is now strong in all the rooms. I originally bought this because the wifi signal was not too strong in my bedroom. I followed the steps given on the box to set up the extender. I was under the impression that I would see the extender in my wifi options but I only see my router in my laptop only this time the singal is strong. The internet is working fine the speed is enough to get work done.
The problem is if I turn off my laptop and turn it back on and connect to the wifi even though the internet is working (checked it on my cellphone), it doesn't work on the laptop, unless I first connect to a hotspot and then connect to my wifi. Is this a common issue? What can I do to resolve it?
