Overview[edit]

The M20 shares the same hardware as the Linksys WRT310N v2.

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
reboot

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.
