No Network access MC7304

OS - Windows 7 Embedded
Modem - MC7304
USB driver build - 4581

I am having issues whereby the modem is connecting to the network, obtaining an IP address but then sits for an average of 4 minutes with no network access (not to be confused with no internet access) and then finally kicks in to life.

I have seen it stuck with no network access for up to an hour on occasion
This happens with my own software, sky light and windows networking.
I have this issue with multiple network providers
I have the same build OS out with customers where the same modem is working instantly

There doesn’t seem to be enough consistency in the fault to pinpoint it so any suggestions are most welcome!

Have to tried with Some other USB driver build? If not then give it a try may be it can be a workaround.

Thanks & Regards,
