I searched the forum but didnt see anything relating to the issue I am having.
Have a new SOHO Surf, firmware 6.0.2. No wired WAN connection in use as I am using UML290 air card (Verizon) via USB as primary wan connection.
Upon boot, air card will connect fine.
Things work fine and I stay connected if I am using my VPN or other web app, such as browser that refreshes automatically. The air card connection stays connected.
If I am not running anything that establishes a persistent connection, after 7 minutes or so, the air card disconnects. After that, it will not connect at all, and shows “Unable to Connect” for the USB interface in the dashboard of the admin page. The only way to reestablish a connection is to reboot the router. System log shows nothing other than USB disconnected. I tried setting the USB “Heath Checking Settings” to ping but that has not helped.
Other settings for the USB include:
Standby State : Remain Connected
Idle Disconnect: Not Checked
Operator Settings: Auto
Am I missing something?
Thanks!
