Cisco 881W Router Config Woes

Hello all, I snagged a Cisco 881W router recently, and tonight hooked up a console cable, and fired up PuTTy to it to see what's on it. The problem I'm having is that when it boots up, it is getting stuck, and not moving any further. I want to recover the password, but I am at a loss. Any break sequence I tried has failed to stop the boot up. I am a Cisco newbie, so keep that in mind. Any ideas?

Hey LinuxRacr, how about now have you tried or know how to make the 881W use 80211.n?
I have 2 881Ws due to a craigslist deal for $175 for both of them, hard to resist right?
Also I might of over did it but I also got a cisco 3750.
Any opinions out there? Did I buy too much or am I on the right path? I play with GNS3 a little bit as well. But really need to learn more and become successful like Linuxracr and multiple others here. Feel free to give me any gouge you can linuxracr. You still have your 881W?

What's required for a VPN server? I want to remote too. (sound like such a loser)

Post 11 in this thread should get you started in the right direction. Another thing you can do is get your hands on the CCP (Cisco Configuration Professional) software to do the EZ VPN configuration from the GUI. It will launch in an Internet Explorer window. If you have issues with the program starting up with only the top of the window showing the interface, try hitting the F12 key, and selecting the compatibility mode.

Here is the latest fun I'm dealing with: My service-module wlan-ap 0 won't startup....

#service-module wlan-ap 0 status
Service Module is Cisco wlan-ap0
Service Module supports session via TTY line 2
Service Module is trying to recover from error
Service Module reset on error is disabled
Service Module heartbeat-reset is enabled
Service Module is in fail open
Service Module status is not available

I had this problem last year, after a power outage that caused me to shutdown my home lab completely for most of the morning. When It came back up, no wireless. I was able to get it working again weeks later after a reload of the unit. A few days ago I had to reboot the router again, and now the wireless module seems not to want to startup.....

When I start a session and authenticate, it hangs there. Any ideas? Is my service-module bad?

I assume you've been reloading the router as a whole?. If you haven't already, I would try just the module: service-module wlan-ap0 reload / service-module wlan-ap 0 reset bootloader

Reload typically sorts out my 887W, the reset would be a little more forceful.

LinuxRacr

Yep, I've done both previously to no avail.

I'll fire mine up when I get chance to see if other ideas spark for diagnosing. You may want to post on the Cisco Forum too: https://supportforums.cisco.com/community/netpro/network-infrastructure/switching . Chances are someone there may have run into the issue.

This is what I have now:

#service-module wlan-ap 0 status
Service Module is Cisco wlan-ap0
Service Module supports session via TTY line 2
Service Module is waiting for registration message
Service Module reset on error is disabled
Service Module heartbeat-reset is enabled
Service Module is in fail open
Service Module status is not available

Can you session into the service module?

service-module wlan-ap0 session

I missed this sentence. Did you wipe out all previous configs including the ones in the service engine? I know I had one unit that once I type enable I get no response from the console. Come to find out it had a previous config that disabled console activity. After I bypassed the config I was able to access it normally.

Nice thread! I've been looking at replacing my soho router with something like 881w.
