Hello,

I have just got a TL-WA850RE v7 wifi extender and everything seems to work fine BUT after a while (a couple of hours or so) when I start my Windows PC that is connected to my ZyXEL WMG8924-B10A router (not the extender) it cannot get access to the network / internet.  Notice that my PC is connected via LAN (cable) to the router . (but same issue if PC is using wifi from router )

On my PC I get an error message like this "can't connect to the DHCP server" and it seems my PC can't get ip address from the router. 
 (All other devices connected to the Router (and extender) is still working (they remains  powered on ) )

If I then unplug the Tp-Link Wifi extender and wait for about 30 - 60 sec. my PC automatically gets network/internet connection (and an IP-address) and I can now connect the wifi-extender to outlet again without issues (until I open another PC that has been powered off for some hours).
But after a couple hours where my PC has been shutdown I have the same problem again - very annoying !

I have tried to disable DHCP on extender but that doesn't solve the issue.  Normally it is set to 'Auto'.

The Wifi extender is set to use same SSID as the 2.4 Ghz SSID on router (5.0 GHz net has another SSID on router) - all other settings on Extender is default .

To me it sounds like the Tp-Link Extender somehow prevent my Zyxel router to provide an ip-address to my Windows PC . 

( I can see that the Ip-adresses on devices connected to the Extender starts from 192.168.1.100  )

!! After some testing it seems it's working fine if I change the SSID on the extender - adding _EXT to the name, but I prefer using the same SSID as my router on the 2.4GHz wifi .!!

Please advice.
