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. To install the image we have to setup a TFTP server on our Ubuntu/Debian system. We assume you have opened a… Read More »
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 »
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 »
Today I've got a Zyxel NWA 3160-n AP, and I turned it into managed mode to try to connect it to my open source CAPWAP AC. No luck so far ... Concerning CAPWAP, Zyxel seems to be in no way better than Cisco. The Zyxel AP is (as almost expected) not really CAPWAP-conform, just like… Read More »
As I wrote in my last post the Cisco LWAP resets it's clock to zero before joining the WLC, and my assumption was, that the WLC has to send the current time within the discovery response message encoded in a vendor specific payload. Some digging throw the web and experimenting led me to the right message… Read More »
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 »
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 »
A few months ago I did a survey about open source CAPWAP access controllers, but did't find any satisfying solution. There was one project with a partial working AC and WTP, but the source code was a very good example for how to not to write C code, so I did't wanted to develop on… Read More »
