On thread of many on the DD-WRT forums, pointing to Eko's recent builds as supporting the M20, as of 09/08/2011 the latest build is 17804

To get HT40 support in the 17804 build, telnet into the router and run the following commands..

nvram set wl0_nbw_cap=1
nvram set wl1_nbw_cap=1
nvram commit

While the device is not listed on the support list, it works with TomatoUSB (K2.6 NoUSB-STD) as of 10/13/2011.

"3763-02010206R" is silkscreened on the board in the FCC photos.

M20 serial numbers appear to start with CVK0.

The default SSID is CiscoXXXXX where XXXXX is the last 5 digits of the serial number. If the device has been configured with Cisco Connect the device will probably have a randomly generated SSID. A sample serial number is CVK01K427671

The included power adapter is a Bestec EA0121WAA.
