I have random ping timeout about 20-30 packets are lost. This happens at least once in every hour, home office VPN connections drop etc, really annoying. Mobile 800MHz hotspot is more stable, but slower. LTE connection does not drop. Before and after the packet loss, avg ping is 17ms. This LHG LTE device is about 4 years old, is the modem failing or could this be configuration error?
