LTE suddenly stopped working

Ia the middle of streaming a film, the LTE connection stopped and I couldnt connect the router to my isp at all any more. When I moved the SIM back to my old router, the connection worked fine.

Im using a external 4G antenna on my rooftop of the house, it have worked flawlessly until it stopped working, and I havent messed with the setup - can the LTE module burn out?

And if it is burned out, would this work in the router:,searchweb201602_3_10065_10068_10000009_10084_10000025_10083_10000029_10080_10082_10081_10000028_10110_10111_10112_10060_10113_10062_10114_10056_10055_10054_10059_10099_10078_10079_10000022_10000012_10103_10073_10102_10000015_10096_10000018_10000019_10052_10053_10107_10050_10106_10051,searchweb201603_1,afswitch_2,single_sort_3_default&btsid=b9c3415e-497f-43c1-89bb-d9e91820f9fd
