I recently updated my router to an Archer BE230. That went perfectly.  I tried to update my current TP-Link extender (RE315) to use the new router.  This process appeared to work perfectly.  That is, until I connected my phone to the extender and got no internet.  I reset the extender to the factory settings and tried again.  This gave me the same results.  Anybody got any suggestions?  On my phone the extender witll show 5 bars but no internet.
