You have to find the support for the product. I'd work back from where you bought it and if it fails to operate at all, go for a refund.
I have bought cheap not branded chinese 4G USB modem (dongle) with hotspot function. Now that product is removed from product list and not possible to find the same modem (could be removed because of bad quality)
Problem is that it is not working. I see it is possible to connect it like modem on Linux with wvdial, but I cannot to share WiFi. What can I do? Maybe I could change firmware for it? Or write a code for it? Any solutions?
Thank you
