The rm520n-gl module was switched to RNDIS mode by me, and I used the 2.2.14 version of the windows driver you gave me, which cannot be fully driven. The device manager keeps flashing, and the at port cannot switch to other modes because the driver does not take effect. I heard that there is a 2.3.1 windows driver that can solve this problem, can you send it to me? If not can you help me find it? I can’t figure it out, because the driver can’t switch to other modes, so it can’t be used, or is there any way to restore the factory settings? Except for at, because it is no longer effective.
