If you want to Connect any DVR to the Internet Just in 1 Minute don’t
want to deal with wires and still want to remain connected to the
internet, using a Bluei 4g router with sim card is the best option. That said, even your
wireless router is using a cable to bring the internet to your home. So,
you are not entirely wireless, are you? Well, if you want to become
truly wireless, you need to use a wireless router that uses SIM cards
instead of ethernet or a cable connection.
