I setup the above extender (TL-WA850) without a problem. My questtion has to do with my smart phone.
I have an S8 Samsung smart phone.
I am connected to the main wireless router (Norton Core) when in the main part of the home.
If I go into the remote area, the phone will seamlessly connect to the extender.
When I return to the main part of the house, the phone will not let go of the extender and connect to the router again. I have to shut off the wifi on the phone and restart it. Then it will connect directly to the router. Trouble is, if I'm not paying attention, I will loss notification of messages and/or cannot download video or picture until I do my little wifi dance with the phone and reconnect to the rounter.
If you have this problem or any ideas, it would be greatly appreciated.
