This is constant problem with this modem, the Optus solution is to do a factory reset. The onscreen yellow message mobile broadband disconnected always appears but without the connect/reconnect button. Optus pushed out a firmware update about 4-6 weeks ago but this made no difference to this issue. I find it often happens when the modem has fully charged and remains in the charger. Maybe it is battery overheating issue (which I've seen suggested as a cause). In my experience the modem does not travel well either, it produces the same message when left on and moving the modem around. If I have to move it I turn it off and then turn it on again. I have to reset it about 4-5 times a week due to the mobile broadband disconnected message. I can't wait until my partner's contract ends and we can buy something that works properly.
Thanks for the detail in your response, Antsa.
A Customer Relations representative will be in touch with you within 10 business days from the date you logged a TIO complaint. Based on what you described, I'm confident the billing issue will be resolved fairly quickly. Let us know how you go.
That is really great of you Rando, thanks heaps for taking the time to post your solution to this issue ☺️
HI Ray_YC, how is that a solution? The modem is supposed to work as 3G and 4G modem and on both the 2.4 GHz and 5 GHz bands. While I suspect Rando's solution will work for some, what about those users that have older equipment with 2.5 GHz wifi and/or live in 3G only areas? It still doesn't change the fact the modem does not work as it should and Optus is apparently ignoring the issue.
I'm not in technical support david71marshall but based on what you have described you are experiencing I would be contacting that team and requesting a replacement.
