Are you sure you have the right part number the ZTE AC2791 does not run LTE.
First you must be very very sure you have the right module number.
There are a couple of broadband router manufactures. You can try cradlepoint,tp-link,netgear & dlink.
The major problem is you are going to have to dig though their compatibility lists. In addition to needing to have the part number of the modem it makes a difference who the ISP is. Sometimes they support the modem only on certain ISP (Mostly because some ISP intentionally prevent using it on a router) Since LTE products are coming onto the market very quickly and there is huge variation on the frequencies they run on between countries and ISP the router manufactures may not yet have support.
