Ange Extender for wireless system


I have a Huawei LTE CPE B315. with sim card (so I don’t have option for Ethernet). I bought a TP link 300 Mbps so I can extend coverage and use in my garage 15 meters from house, signal was weak (even when plugged in closest socket to garage. I then exchanged it for a TP link AC1200 wifi but not much improvement. What are my best options? Should I just buy 2 or 3 TP link 300’s or??

Please help.

I didn’t find the right solution from the Internet.
