Hello all,
I have this problem with Huawei E355, it stops connecting to internet after every 5mins, until you restart the router.

This problem has been happening and not working well as required. I have created dhcp client with lte as the interface, can log to the Huawei E355 with 192.168.1.1.

How can I Change this USB Huawei E355 from hilink to ppp mode, (from the lte to ppp-out) so that it can allow me access the internet. Thanks and hoping to get answer from here.
