I have a Cisco 881G with PCEX-HSPA-3G card for which I have successfully configured for internet.
As the above one has come to end of life, we got the replacement 881G with embedded 3G modem.
I can't get Cellular 0 to use ppp encapsulation:
Cellular0: Only SLIP encapsulation supported
This is on a Cisco 881G, the IOS is below
Router#sh ver | in bin
System image file is "flash:c880data-universalk9-mz.151-4.M4.bin"
Could you please help me if you found any solution??
