Hi @Vantagepete! I regret to hear this.. Did you try to disconnect the modem from every other networks and modems? I recommend you to read this article:...

@ShikharC Did you try to restart the router? If it doesn't work then, maybe you could set your router back to its factory settings. (The update of the firmware could have confused the router.)

This really helped me with my problem. I was bit afraid, that I wouldn't find something that could solve my problem. I tried it and it worked. Thank you for posting this.

@alfonso.vin The problem could be the Catalina OS. Since the Update 32-bit applications don't run anymore. Maybe this link can help you:...

@ksaefos If nothing works, you could always try to contact the support service directly. Asking them wouldn't hurt.

@Kiran001 Did you have time yet? I am interested to know if the update was the solution to the problem
