Peplink balace 210 speedfusion VPN Bonding with Pepwave Max BR1 Timeout during a ping

Hello, Please I really need assistance in this issue with speedfusion VPN Bonding. I have a Peplink balance 210 and a Pepwave Max BR1, and I did a speedfusion VPN Bonding on the balance 210 to bond with the Pepwave in PepVPN mode with a WAN connection over a radio link. After all, I connected one laptop each on both ends and try to ping, it does ping but timeout about five lines and continues to ping and timeout again. Please what could be the problem? I will really appreciate any support.

It sounds like it could be an issue with the radio link. What is the quality of the radio link outside of PepVPN?
