I have Huawei E5786Bs-32a. Changed firmware from telenor brand to 21.313.17.00.00 (without brand). Unfortunatelly it was firmware to E5786s-32a.
Now 4G range is very low. Similar router E5577 with simcard of the same operator has max 4G range.
Is this firmware could be a problem? I didn't noticed if low 4G range was before firmware change.
I have searched for proper firmware and Web UI to download but without effect. Even Huawei service in Poland can't help.
Can someone help me?
Sorry for my English.
