TELKOM LTE wireless

In the past few weeks with Telkom's wireless LTE network, it was not a pleasure using your network at all! The package comes with a HUAWEI 4G router. Every single day the network changes to 3G making it impossible to use the internet and have to restart the router for about 5 times a day. It is getting ridiculously worse that makes it impossible for some of us to work while relying on the network that changes to 3G 5-7 times a day. Is there not a solution for this? I can guarantee that it is not the router that is faulty.
