HWIC 3G

supportalliacom · ‎04-12-2016

Hi,

I have configured HWIC 3G cellular interface on a 1841 router.

When I reload the router the interface get an IP address and traffic pass to internet, but after sometime the cellular interface is reseting and the interface is is not having any ip address no traffic pass .

Im attaching the router configuration please help me on this.

Philip D'Ath · ‎04-12-2016

Nothing attached. Also what IOS version are you using?

Are you able to upgrade to the gold star release 15.1.4M10 ?

supportalliacom · ‎04-14-2016

Hi,

I have upgraded on 15.1.4M10 now it is worst, the interface gets up, after that immediately resetting and then going down.

*Apr 14 09:46:04.523: %LINK-3-UPDOWN: Interface Cellular0/0/0, changed state to up
*Apr 14 09:46:06.587: %LINK-5-CHANGED: Interface Cellular0/0/0, changed state to reset
*Apr 14 09:46:11.587: %LINK-3-UPDOWN: Interface Cellular0/0/0, changed state to

Thanks for your help.

Philip D'Ath · ‎04-14-2016

Wow that is a bad reaction. Try powering the router down, remove and re-insert the HWIC card (re-seating the card) and then power back on.

The 3G modem is not acting like it is very happy.

supportalliacom · ‎04-15-2016

I have powerd off the router re inserted the card but it is still the same.

Even i have performed a modem upgrade nothing changed .

Thanks,

Philip D'Ath · ‎04-17-2016

I don't think you should have "password sfr" on line 0/0/0. That line is used by the router to talk to the 3G modem. Try removing it.

Perhaps try changing:

ip route 0.0.0.0 0.0.0.0 Cellular0/0/0

to:

ip route 0.0.0.0 0.0.0.0 Cellular0/0/0 permanent

supportalliacom · ‎04-20-2016

Hi,

I have modified the default route as you said, but nothing changed.

When i restart the router i get below message:

could you change the chat-script below to "OK" and try again?

Hi,

normally it should look like this.

(this is lte 4G stuff so it is a little different)

attach profile under controller cellular first

controller Cellular 0
lte sim data-profile 1 attach-profile 1 slot 0
lte gps mode standalone
lte gps nmea

configure chat script

chat-script lte "" "AT!CALL" TIMEOUT 20 "OK"

interface Cellular0
ip address negotiated
ip virtual-reassembly in
encapsulation slip
dialer in-band
dialer string lte
dialer-group 2

dialer-list 2 protocol ip permit

ip route 0.0.0.0 0.0.0.0 Cellular0

ping to the outside when debug is activated. This should do it.

Kind Regards

Jan Meylaers

supportalliacom · ‎04-22-2016

Hi,

Thanks for replay, but under controller cellular 0 i dont see the option lte.

Router(config-controller)#?

Hi,

you do not need the lte command as you are having a 3G router.

I have found a 3G router configuration.

Hellow,

I have a Cisco router 1841 with a HWIC 3g card.

I have configured site to site VPN with a cisco ASA, the configuration is working well but I have very high latency around 400 to 500 ms.

When i reboo the router the latency is around 100 ms for some minutes and then insreases, even the traffic is not increasing the latency insrease after some minutes.

Below is the router configuration :
