I today received my TL-MR3420.
I have followed all installation instructions, other than disabling pin verification on the sim, as I dont know how.
Upon plugging in the router, it says the USB modem is not recognized, and to install its config file.
Here is my modem:
I believe it is a ZTE MF636? According to the TP-Link website, the routers latest firmware is compatible with this. I have tried uploading the two config files I found in the Telecom Connection Manager folder, but they didn't work.
Does anyone have any idea how I can get this to work?
