MC7304 Driving me nuts!

Hi Guys,

Thanks for the replies.
Yes, have tried uninstalling all drivers, skylight etc… no difference.

Ok, I have identified the problem and when it happens - but not the root cause.

I have an older MC7304 that was in one of our other PC’s SKU: 110241.
All of the new modems I received are SKU: 1103054

The older model (110241) works flawlessly, every time.
When I install the newer modem (1103054), there is no issue “until” I enable auto connect either through Windows WWAN or Skylight. As soon as I do this the modem will connect and disconnect until what I think Sierra have described as SED (Smart Error Detection). Once this happens the only way of getting back in is to run a firmware update and quickly uncheck the auto connect.

I have tested this a dozen times with the older model and the newer model - and it is consistent. I need to find out what is different about it.
I have emailed support about this but heard nothing back.

Anybody have any idea what is going on?

Thanks in advance!
