WRN 3000 RANGE EXTENDER. My mobile connects and has internet, my laptop connects and has none

Hi all,

I have Windows 10 and the above range extender. Until a month or 2 ago I connected both my mobile and laptop to my network through it.

Now I can still connect via my mobile but when my laptop connects it has no internet?

I have flushed dns etc, reset my network, changed dns to 8.8.8.8 and 8.8.4.4, essentially every solution I could find on the internet but nothing has worked please help. By the way if I move my laptop close to the router it can connect, only when through the extender do I have no internet

 Thank you in advance
