TP-Link TL-WR802N v4
Supported Versions
Hardware Highlights
Installation
The only way to flash the image in TL-WR802N v4 is to use tftp recovery mode in U-Boot:
- Install a TFTP server application. For Windows “tftp32” works. For Mac “Pumpkin” was the easiest method for me.
- Configure PC with static IP 192.168.0.225/24 Alternative server IP address that worked for me was 192.168.0.66
- Rename
openwrt-ramips-mt76x8-tplink_tl-wr802n-v4-squashfs-tftp-recovery.bintotp_recovery.binand place it in the TFTP server folder. - Connect PC with the LAN port, press the reset button and switch on the router, keeping the button pressed for around 10 sec, until device starts downloading the file. Pumpkin on Mac by will ask you to approve the file transfer.
- Router will download file from the 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.
- Once the LED turns solid, the upgrade should have been completed.
- Configure your client to DHCP client again, 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.
