Flashing
 | NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing OpenWrt
 | This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details. |
| This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now. |
| OpenWrt support for this device has ended in 2022. 19.07.10 was the last official build for 4/32 devices. |
