I am trying to use a Huawei aircard modem with my new i-mac without success. This modem works fine on my 10 year old imac.

Because the new computer does not allow a USB device to be plugged directly into the computer, I had to buy the below USB-C multifunctional adapter (front and back of box):

The message I get when I hook the Huawei modem to the new i-mac using the Ugreen multifunctional adapter is:

 

 

Can anybody recommend a solution to this problem? I can't find anything on line specific to this problem, and the Apple reseller I bought the computer from is completely unable to provide any technical support. Is an updated aircard modem the solution? If so, can anyone specify a specific make and model? Could the problem be that the aircard modem isn't compatible with the UGreen multifunctional adapter? (I noticed that on the back of the UGreen box, the adapter I was sold seems to be designed for Apple laptops and i-macs aren't specifically mentioned as being compatible with the UGreen device.) If the adapter is the problem, can anyone recommend another brand of adapter which would work?

 

I am aware of 3BB and other fiber optic options to connect to the internet, but there are logistical reasons which would make a fiber optic connection difficult, so I would really like to see if I can connect to the internet using an aircard modem.

 

Any suggestions or solutions would be gratefully appreciated.

 

Thanks.

Have you tried updating the HiLink 3? Or googling for how to update it?
