Cisco 837, CRWS not working, tried everything.


I have a problem with Cisco 837. First of all, I didn't set it up. It was setup ready by the fellows from the phonecompany. Everything is running fine, internet and other connections work how they are supposed to but I can't access any settings through CRWS. I just get the "page not found" when I try to access the default address . I have also tried the address . I went through the password recovery procedure to gain access to the CLI settings, but I have no idea of what to do to get the CRWS to work. I know CRWS is installed on the router and I know SDM is not. I have tried everything described in the quick start manual. I also tried giving the Ethernet0 an IP address, that didn't do anything.

The router is connected to a switch to wich all the computers are connected. Computers have the an IP of 192.168.1.x in subnetmask. And router has static IP from the ISP. There is also some sort of decrypted bridge connection to another network.

I'm not really sure of what info you would need but here is the running-config

Re: Cisco 837, CRWS not working, tried everything.


Would you be able to enter the following command in configutation mode:

ip http server

Then, try CRWS again...

Hope that helps - pls rate the post if it does.

Re: Cisco 837, CRWS not working, tried everything.

Thank you, that enabled the CRWS, but now I can only access it from the computer I used the console cable to give that "ip http server" command. And, after connecting to the CRWS and giving the password, I get message that

"CRWS can't communicate with the router,please check cables and that computer is set to retrieve IP address automatically."

Now, if I set my computer to retrieve IP address automatically, I lose all connectivity and can't even access the router through . What would you suggest? btw, I'm using win98 with IE 6 to access the router, hyperterminal when using console cable.

there are a couple of things to keep in mind when using CRWS, check the link below:

OK, I'm starting to lose my mind with this. I was able to succesfully connect with web browser to the router from my Win XP machine.

I didn't change any settings in that computer.It has manually set IP address like the rest of the computers but then 30 minutes later when I tried it again, I got the same message "Can't connect to the router. Check connections and that computer gets IP address automatically".

Could this be a problem with IOS version, or CRWS version? What if I update IOS or CRWS or both, will I lose the current settings?

On top of the above, the CRWS stopped working now. Tried to enable it again by connecting with console and giving the command "ip http server", nothing, can't even get that working now again.

This thing amazes me everytime now when I try to do something with it. Now, after the CRWS stopped working again, I tried to connect 2 hours later to find out, the CRWS is working again, I didn't change any settings or touched anything. CRWS still though says it can't connect to the router.

Re: Cisco 837, CRWS not working, tried everything.

From my experience with the 837s, the CRWS is a run-once interface that you will not be able to bring up after the initial configuration...although I don't recall this being documented anywhere I think a Cisco tech told me this when I was having the same issue you are now having. You need to use the SDM to administer the router via a GUI interface after initial installation.

These 2 URLs should get you going:

Hope this helps.

Re: Cisco 837, CRWS not working, tried everything.

Thank you Charles. That would explain the unstable behaviour of the CRWS.

Now, to be able to run the latest SDM, I would need to update the IOS aswell. Problem is, I can't download it. It keeps saying I have guest access and that I need to register. I even registered again, as you can see from my different login, but I still can't download the IOS update. Are updates available only to registered Cisco retailers/contacts/staff etc.?

If I would be able to somehow get my hands on a updated IOS-file, would I lose my current config if I update IOS?

Sorry for the unrelated stuff but being able to download is kinda relevant with this.
