You sure can, as long as you have a signal
Do you know if it is possible, via IOS, to show the details for all visible cells - not merely that to which the unit is currently registered…? Could be handy for geolocating a remote device…
Not that I know of…I checked all the cellular commands but I think it only shows the cell that it is connected to.
How can I find out how good my signal strength is of a router that is Connected some were?
Sorry for bad English…
The show cellular 0/1/0 radio command will do the job but you need to have access to the CLI of the router.
Great explanation! I have almost identical configuration, and connection is established (got IP and DNS addresses) , but I can’t ping anything from router via Dialer interface. I can’t even ping Dialer’s address (which I got from ISP and can be seen with sh ip int brief command) itself???
Hi Rene, I really enjoy your site full of plenty useful clear and easy to read information…
One quite question:
Does this HWIC-3G-GSM WAN card supports 1700 series cisco routers…
typo; Not (quite but quick ) above…
You are welcome. The HWIC-3G-GSM WAN card is not supported on the 1700 router. For each interface card you can find the supported platforms. In this case:
Modular Cisco 1841, 1861, 1900, 2800, 2900, 3800 and 3900 Integrated Services Routers
You can find it here:
If you get an IP address then your connection itself should be OK. How about a default route? Is it pointing towards the ISP / out of the dialer interface?
I’ve found where is problem. The ISP allows me to communicate (ping) with only specified range of ip addresses within my APN. A communication with them works like a charm and that is exactly what I need! Thanks for great lessons and really quick answers!
When i do a show cell 0/1/0 hardware on my HWIC-3G_GSM it comes up with the following output:
Modem Firmware Version = Modem Firmware built = Hardware Version = International Mobile Subscriber Identity (IMSI) = 00000 International Mobile Equipment Identity (IMEI) = Integrated Circuit Card ID (ICCID) = Mobile Subscriber International Subscriber IDentity Number (MSISDN) = Factory Serial Number (FSN) = Modem Status = Offline Current Modem Temperature = 0 deg C, State = Normal PRI SKU ID = 0, SKU Rev. = 0.0 R2851#
It shows that there is no firmware installed. Does this represent a problem?
I don’t think it’s an issue. There are different radios, firmware and IOS versions. It could be a cosmetic bug.
You might want to configure it, see if it works. If it doesn’t, you could try to install the latest firmware and/or try another IOS image.
Hi, I have a doubt an ISP is going to install an APN for some links what I have to configure on my LAN to receive the APN?
Hmm good question, I doubt you can automatically receive the APN. Normally we configure it manually on the router.
Hi Rene, i am trying to play with 4g-lte-ga and when Im trying to configure
dialer pool-member 1
%Remove Leagacy DDR configuration first
can you help me out here please ?
It seems that Legacy Dial-on-Demand routing (DDR) is configured on the router. This means that one or more of the following commands are enabled on the router:
In Global Configuration mode:
dialer dtr or
dialer inband <em>parity</em>
On some interface:
dialer string ... dialer map dialer-list dialer-group dialer enable-timeout dialer wait-for-carrier-time dialer priority
Check both physical and virtual (dialer and otherwise) interfaces for any such configurations and remove them.
You might find some additional information here: http://www.cisco.com/c/en/us/td/docs/ios/12_2/dial/configuration/guide/fdial_c/dafspoke.html#wp1000999
I hope this has been helpful!

For some reason my cellular interface on the router is not telnet/ssh able.
When the cellular interface comes up its pingable but we cant telnet/ssh it.
Did a wire shark,
tcp syn tcp syn ack ack sshv2
then loads of the errrors below before timing out.
5591 283.604252 x.x.x.x x.x.x.x TCP 82 [TCP Retransmission] 64464→22 [PSH, ACK] Seq=1 Ack=1 Win=65392 Len=28
Any chance the ISP is doing some carrier grade NAT or filtering anything? I’ve had issues like this before with site-to-site IPsec VPNs.
