When using this device connected to a convexa B1300, I found a strange anomaly from ipa3_wan_ioctl. The connection randomly drops on the WAN of the convexa B1300, and the only way to get the link up again is to either set a static IP (but the issue occurs later on) or renew the DHCP lease and obtain a new IP address. This issue doesn’t happen on USB (ECM, usbnet=1).
