Help configuring LTE 4G on Cisco C887VAG-4G-GA-K9

[bsgd]

Hello all,

First of all let me tell you that Im am completely new to Cisco products and this is the first time I am trying to configure a Cisco product. I run an small business and have just bought a brand new LTE router.

I have the SIM card in and after accessing the default router address 10.10.10.1 I started the QUICK SETUP WIZARD. I just let everything set at default, but at the end, when I click the SUBMIT button, an error comes up saying: "Invalid input detected. Command: dialer string"

Below is the automatically generated CLI that I get when I click CLI PREVIEW.

I do have the knowledge to configure regular household routers, but this Cisco seems like a whole different beast, so I need some step by step help. All I want to do is get internet from my 4G provider, and thats all.

Thanks everyone and sorry if I am missing something obivous. I did try going into advance configuration mode and trying to check the 4G LTE interface as MAIN WAN INTERFACE but a message saying "APPLYING" pops up and never finishes, I have to close Chrome and restart all over.

No, I had only one SIM in slot 0.
Im away from the router now but will post back the requested info in a few hours with a second SIM inserted in slot 1.

Thanks again, you've been very helpful.

[bsgd]

Sorry for the delay, I have been out of town for a few days but will be back tonight and get both sims in the router.

Just wanted to let you know why I still havent posted back :)

Thanks.

Hello Georg,

I have just reconnected my router, and it looks like after been off for a few days it lost all config, and I had to do it all over again!
Is this excpected to happen? I dont think so, and Im kinda worried since this is a brand new router.

[Georg Pauwen]

Hello, 

did you issue the command below:

877#copy run start

This will save your running config to a file called startup config, which is permanently stored in your router memory...

[bsgd]

No, I didnt. I only used the WR MEM command as suggested.
What is the difference between the two?

I just got myself a C881W (to use as an access point along with the C887 for WI-FI) and I am having a very hard time getting it running too, even after trying to follow the steps at http://bogomip.net/blog/configuring-a-cisco-881w/

[Georg Pauwen]

Hello,

wr mem and copy run start should in theory do the same thing...not sure what went wrong. Try and issue both commands, then do a 'show startup-config' to check if the startup file matches what you have configured.

Regarding the 881W, how is that connected to the 887 ? Post the config of the 881W you have so far...

[bsgd]

OK, So I will retry using both commands on the 887. I'm just setting up both routers on my bench now so I can try to get them going and talk to each other. All I need is to have a WI-FI network with internat access from my LTE SIM card. I have been using regular routers for this, but the are very unrealible,and thats why Im now trying to get something a little better.

The 881W FE LAN 0 port is directly connected to the 887 FE LAN 0 port. Right now its back to factory since after following all the step by step commands llisted at http://bogomip.net/blog/configuring-a-cisco-881w/ I ALWAYS end up loosing connection to the router (by TELNET) after issuing these commands:

interface FastEthernet0
switchport mode trunk
exit

After that its just plain impossible to reconnect at any address and I have to restart all over after a factory reset. Maybe I sould try using the controller to serial cable and a USB to serial adapter? No sure.
These Cisco routers are pretty complex to configure and debug when something goes wrong.

[Georg Pauwen]

Hello,

if you initially set up the routers, better use the console port and a terminal emulator such as Putty, that way, you won't lose connectivity if you misconfigure something...

[bsgd]

Thanks again Georg for all the help.

OK, so now Im focusing on the 881W to try to make internet available through WI-FI. I have factory reset it once more and connected it using a serial to USB adapter and Putty. I get the window below, but it wont accept 'regular' commands as before (whe I was using telnet).

I just get a Router> prompt, but typing CONFIGURE TERMINAL gives me an error.... please see attached pic.

[Georg Pauwen]

Hello,

You need to be in exec mode. Type:

Router>enable

Then enter the password (default is admin or cisco)

[bsgd]

Thanks, I will stay up late tonight and try to configure it myself using the tutorials I found online.

Will post back tomorrow how it went :)

[bsgd]

So, I have been reading a lot and managed to get internet through wi-fi using my C887 and Cisco881W. I have managed to enable WPA2 and setup my SSID on my CISCO881W. But I still have a few questions:

1- Im a little confused on how to correctly set the routers up. My C887 has DHCP enabled and my Cisco881W also. At first I thought they would not work like these but they do. Why?

2- Is there a way to download the COMPLETE router config so if anything happens I can just reaload a file using some command and get everything working again?

Thanks again :)
