OEM easy installation
These devices can be easily flashed through the generic CFE recovery webserver:
- Press and hold the reset button
- Power on the device
- Wait until the power LED turns solid red (after about 30 seconds)
- Browse to
http://192.168.1.1/ - Upload the image

Network interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
|---|---|---|
| br-lan | EXAMPLE LAN & WiFi | EXAMPLE 192.168.1.1/24 |
| vlan0 (eth0.0) | EXAMPLE LAN ports (1 to 4) | EXAMPLE None |
| vlan1 (eth0.1) | EXAMPLE WAN port | EXAMPLE DHCP |
| wl0 | EXAMPLE WiFi | EXAMPLE Disabled |
Switch Ports (for VLANs)
Numbers 0-3 are Ports 1-4 as labelled on the unit, in reverse order (so internal port 0 is external 4, 1 is 3, etc).
| Port | Switch port |
|---|---|
| CPU | CPU |
| Internet (WAN) | Port 4 |
| LAN 1 | Port 3 |
| LAN 2 | Port 2 |

Leds
There are five user configurable leds on the unit:
- 2x bicolor green+red (“Power”, “Internet”)
- 2x unicolor green (“WLAN”, “DSL”)
- 1x unicolor blue (wps-button)
They are accessible as:
| description | device | comment |
|---|---|---|
| “Power” (green) | /sys/class/leds/dsl-274xb:green:power | |
| “Power” (red) | /sys/class/leds/dsl-274xb:red:power | |
| “Internet” (green) | /sys/class/leds/dsl-274xb:green:internet | |
| “Internet” (red) | /sys/class/leds/dsl-274xb:red:internet | |
| “WLAN” (green) | /sys/class/leds/b43-phy0::rx | recommended trigger: “b43-phy0::rx” |
| “DSL” (green) | /sys/class/leds/dsl-274xb:green:adsl | recommended trigger: “netdev”/“eth0.2”/receive (in case eth0.2 is manually configured as WAN interface) |
| wps-led (blue) | /sys/class/gpio/gpio498 | Low-active wiring! Setting value '0' turns led on, value '1' turns led off. |
The “class/leds” devices are accessible over the web interface. To access the “class/gpio” devices, refer to port.gpio!
Buttons and switches
There are two user configurable buttons, and one user configurable switch on the unit:
| description | device / scriptfile | comment |
|---|---|---|
| button “RESET” | /etc/rc.button/reset | Already in use for functions 'reboot' and 'restore defaults'!!! |
| switch “WIRELESS” | /sys/class/gpio/gpio508 | Low-active wiring! Reads '0' for position “ON”, '1' for “OFF”. |
| wps-button | /sys/class/gpio/gpio509 | Low-active wiring! Reads '0' when button is pressed, '1' otherwise. |
As of firmware 15.05, the script /etc/rc.button/rfkill is not triggered by the switch “WIRELESS”.
To access the functions of “rc.button” devices, refer to hardware.button! To access the “class/gpio” devices, refer to port.gpio!
Opening the case
Note: This will void your warranty!
For Revision C3 (and probably C2):
- Remove the screws under all four rubber feet
- Lift the black top lid from the silver middle part: Holding clips are on each side in the fifth venting hole counted from the front. Insert a small screwdriver or similar vertically to release clips.
For Revision F1
This model is tricky to open as it has a total of seven plastic clips holding the top. You might need brute force, and there are chances you will damage your case.
- Remove the screws under all four rubber feet
- For the front clips: using two flat head screw drivers push bottom “grill” out until you can lift the top slightly
- For the front side clips: using a flat head screw driver push the bottom out until it clicks (slide it in from the corner, then work yourself to where the clip is)
- For the back side clips: these should be easy now with some wiggling

Wireless - for Revision C3
As the wlan chip is not starting up with a valid mac-address, the driver will not upload the chip's firmware image until there is a valid manual MAC configuration.
Adding mac-address for access-point mode. This fix only works for access-point mode, so e.g. scanning for WLANs won't work, since this is switching the unit to station mode.
Wireless - for Revision F1
got broken, missing sprom fallback, caldata not extracted. kmod-owl-loader still not working
Reverting to original Firmware
