Issue setting up my netgear extender (ac1750 ex6250v2) and my netgear nighthawk M2 mobile 4G routeur

Hello,

I tried the suggestion ( thanks for it ) and it did not work at all.

I reset the extender to  factory

I switch the button to access point

I connected the router to the nighthawk mobile modem 4G LTE M2( MR2100) and tried to do the setup

I finally accessed the extender and did the setup but :

-> no way to have a working connexion between the extender and the modem ( and the RJ45 cable works perfectly, the lights were on on the connectors on both sides)

When I am connected to the modem M2 , I do not reach the extender

When I am connecrted to the extender , it does not reach the modem

I did another test with another extender (from another brand) and it worked like a charm with the M2.

So this is very bothering.

I have a 4G Modem MR2110 from netgear and and extender from the same brand and they just do not work together when they work with other devices from other brands . This is frustrating  as I bought the extender specifically to work with the MR211.

Any suggestion is welcome

Regards
