The only way to flash the image in TL-WR802N v4 is to use tftp recovery mode in U-Boot:

  1. Configure PC with static IP 192.168.0.225/24 and tftp server. Alternate server IP address that worked for me was 192.168.0.66
  2. Download a tfpt server application. For windows “tftp 32” works. For Mac “Pumpkin” was the easiest method for me.
  3. Choose the default (root) directory for your server.
  4. Rename openwrt-ramips-mt76x8-tplink_tl-wr802n-v4-squashfs-tftp-recovery.bin to tp_recovery.bin and place it in tftp server directory.
  5. Connect PC with the LAN port, press the reset button, power up the router and keep button pressed for around 10 seconds, until device starts downloading the file. Pumpkin on Mac by default will prompt for approval for the file transfer.
  6. Router will download file from server, write it to flash and reboot. The reboot process takes a couple of minutes. The light on the device will cycle through various patterns as it updates.
  7. When the light on the device settles on solid it should be fully rebooted.
  8. You can now set your computer to receive a DHCP address and login to the web GUI at 192.168.1.1

Energy consumption

This device uses 1.3 watts at idle with OpenWRT and 4 SSIDs configured. Measured with high accuracy ELV Energy master.

Wireless hardware details

Even WR802Nv4 is sold, there are hardware differences. Devices beginning with serialnumer 219 and 220 support 25 dBm maximum transmit power, whereas devices with serial number beginning with 221 support only 22 dBm maximum transmit power. In all cases Wifi chipset is MediaTek MT76x8 802.11bgn. Or maybe this is dependant on TP-Link department. So italy would be 25 dBm wheras Germany would be 22 dBm, details see here https://forum.openwrt.org/t/wr802n-different-maximum-transmit-power-depending-on-batch/116958/6

Up to 4 SSIDs are supported on all those versions.

IEEE 802.1Q VLANs are supported.

Output of iw phy for all for Italy / 25 dBm version with country code AU.
