Hi,

I'm using Tp-Link Archer VR2800 modem. this modem has 3G/4G optional connection.

I'm not able to make it work.
I'm using ZTE mf833v LTE USB modem 
I tested the USB modem & it working - so the modem fine

I try to change the VR2800 'operation mode' to '3G/4G Router mode'  - but I didn't get any internet connection
I also try to manually insert the cellular network 'APN' number - still didn't work  (when I use the USB modem on my laptop I didn't need to change any default value)
I try both of the VR2800 USB ports - didn't work on both of them

When I insert the USB modem, I can see the status 'Detecting...' under USB sharing > 3G/4G setting > 3G/4G USB modem.     *after a while the status change to 'unknown'  

When searching the web for 'download ZTE MF833.bin file' to upload to tp-link modem. 


Does someone know how to make the 3G/4G connection on tp-link router to work?

TNX
