I bought two WR11XT routers and on both of them I have strange behavior.
Routers seem to have problems when I insert specific SIMs. When I insert a specific SIM (the one I should be using) the router does not work, it does not connect to the Internet and the ethernet connections are unstable.
If I change the SIM, for example that of my cell phone, the router works fine. I have tried with different SIMs and the problem occurs only with the two specifications that we should use. But these SIMs work because if I put them in a cell phone or another router, everything works. It seems these routers are incompatible with these SIMs ... Anyone have any idea what I can do to fix?
Thank you very much
