Background:
Huawei 3272 4G connection on computer is ~24Mbit up and ~12Mbit down. Ulimited bitrate - only sky is the limit and signal strength is very good, but:

Problem 1: DIR-825 with DD-WRT25544 exactly 8Mbit down and exactly 2Mbit up. Looks like something is restricting speed. Force 4G is on and LTE dial string is used. I suspect that only 3G connection is used.

Problem 2: DIR-825 with DD-WRT26424 (latest beta) does not connect at all. Not big surprise as others have also problems with Huawei and versions > 25760.

Old firmware does not connect LTE and new versions does not connect. Connect button is grey - maybe 4G modem detection problems, maybe just one of recently introduced button bugs.

What to do? Some custom init strings? I cannot find method to use them. Help !
