I want to let my Brightsign device register to Brightsign cloud platform through LTE Internet. I found it only works with MR100 plug and play. After I run the "quick setup" of MR100, my Brightsign device will be never online on the BSN platform, however, my laptop on the second LAN port can access to the Internet without any issue.

I tried to turn off firewall, still not working. If I whitelist the Brightsign device (Access Control is off by default), it could go online but if I reboot either the Brightsign or the MR100, it goes offline again forever until I factory reset MR100.

Anyone know what was done during the MR100's quick setup procedure might result as this "blocking"?

Thanks
