4G problem on Cisco 2900 router.

[mohamed.sameer]

I have configured a Cisco 2900 router to support the 4G and I configured a tunnel but the 4G WIC is turning down and on repeatedly!

interface Cellular0/2/0

 ip address $$$$$$$$$$$$$

 no ip redirects

 no ip unreachables

 no ip proxy-arp

 ip flow ingress

 encapsulation slip

 dialer in-band

 dialer idle-timeout 0

 dialer string lte

 dialer string gsm

 dialer string hspa-R7

 dialer-group 1

 async mode interactive

!

interface Tunnel3

 description VODAFONE 4G

 ip address $$$$$$$$$$

 tunnel source $$$$$$$$

 tunnel destination $$$$$$$$

keepalive$$$

!

I don't know what is the problem, the router was working fine till yesterday! 

there's nothing wrong with the operator just in case you're wondering, there are some other routers that are working fine.

Could you share your dialer string?

Have you tried power cycling the router?

[mohamed.sameer]

would you tell me please how can I get the dialer string?

and yes I have tried.

[Philip D'Ath]

Your config references "hspa-R7" so look for a script with that name in the running config.  Can you also show your "line" config.

[mohamed.sameer]

would that help?
