Huawei K4203 modem on Arch.

Posted on By pukeko

This is a cheap, locked modem you pick up and then throw away once you have used the data. It is better than the hotel wifi. The trouble is that it is recognised as a data stick by Arch. The cure was defined by some ubuntu people, and works for antergos or arch.
