I have been using USB tethering to connect CCGX to the internet for updating firmware on systems before installing them at customers premises. The last one gave the #154 connection error on site and it had been working before delivery to site . I put this down to a less than ideal mobile phone signal and made a note to test more at a later date.
I have since tested a new CCGX with USB tethering and it worked successfully until I upgraded the firmware to v2.33 whereupon it gave the #154 error.
I restored the factory v2.18 and it connects flawlessly again.
Am I missing something or is there a problem with USB tethering in v2.33?
