Hi Team,
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:
Router(config-if)#encapsulation ppp
Cellular0: Only SLIP encapsulation supported
Router(config-if)#
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"
Router#
Router#
Could you please help me if you found any solution??
Thank You
Arjun

Hi Arjun,
For Cisco 880 series, we need to use IOS 12.4(22)YB1 or above to fully utilize HSPA support.
if you need more info then please check this page:

Hi Sandeep,
Thanks a lot for the reply.
I currently have the C881G+7-K9 with embedded modem where we do not need any express card and just need to insert the SIM card in a slot available behing the router.
So this IOS holds good for this as well?

Hi,
Nope, when I enter the "encapsulation ppp" under cellular interface, I get the error message shown in my 1st post.
Can someone help in getting the updated IOS for c880data-universalk9-mz.151-4.M4.bin

Hi,
Tried that but there is no data for the current IOS I am using.
When try to put the IOS in the Cisco Navigator, it gives an error telling there is no version.
Any help
Thank you
Arjun
