Ok. You want to flash the firmware of a Cisco 1140, Cisco 1130 or any other Aironet AP. So,  download here the desired image you want to install, if you haven't already done so.

Want to SSH or Telnet into a Cisco Wireless AP with Default Username and Password?

By | March 28, 2016

You probably know, that you can't enable ssh or telnet on a Cisco AP, until you have set a custom password, different from the default credentials ( username = Cisco, password = Cisco). The Cisco WLC prevents you from that indeed bad practice. But finally, with AC-Tube, the Open Source CAPWAP AC, you are free… Read More »

Running a Cisco Virtual Wireless Controller in VirtualBox

By | January 10, 2015

Today I downloaded Cisco's Virtual Wireless Controller to play around with. I wanted to run the controller in  VirtualBox, but simply importing the downloaded .OVA file didn't work straight away. After the import was done, I ended up with a virtual machine configuration, where a bootable image was missing. So I had to untar the … Read More »

Some digging throw the web and experimenting led me to the right message… Read More »

Cisco and CAPWAP II

By | August 13, 2014

After some hard days of debugging, coding and doc-reading, today my Cisco 1131 LWAP finally sent it's first  join request to my Open Source CAPWAP WLC (which is still in an early development stage). I faced a number of problems: It seems, nobody in the world has ever tried to join a Cisco LWAP to a third-party WLC,… Read More »

Cisco and CAPWAP

By | July 28, 2014

So now I've got a Cisco Aironet 1131ag access point, and first it didn't wanted to join the AC-Tube CAPWAP WLC (which is still under development). A long night of debugging and reading log files led me to the result that this access point isn't really CAPWAP conform, when using the latest firmware 12.4.25e from May 2014 or… Read More »
