HELP configuring Cellular0 on a Cisco881G

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 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 Sandeep,

I have seen the link and they are for the old type of 881G routers.

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
