Range Extender not working after switching to new router - network disappears after a few seconds
I have been using range extender RE315 AC1200 with a D-Link rounter for years with no issue.
My D-Link router started having problems so I bought a new router TP-Link AC1200 Archer A6.
Got the router set up with no issues, but when I try to connect the range extender to the new router it is not working.
I have followed the steps to plug in the range extender near the router, wait for the power button to turn on, then press the WPS button the router then press it on the extender.
All 4 lights on the extender light up, but only sometimes can I see the _EXT network show up on the wifi list on my phone.
When it does show up I can connect, but the network will disappear within 30 seconds even though all the lights are still on on the extender.
I have to unplug or press the reset button on the extender and go through the set-up steps again to get the _EXT network to show and it always disappears.
