TP-Link EAP615-Wall v1

The EAP615-Wall v1 is an IEEE 802.11ax gigabit PoE+ (802.3af/at) MediaTek-based wall-mount access point. The reverse (back) side of the device has a single PoE+ input ethernet jack. The bottom has three additional ethernet jacks with one providing pass-through PoE output.

This is one of the few access points available that is Wi-Fi_6 capable.

Installing OpenWrt is relatively trivial. Turning off certificate verification via the device CLI (typical for newer TP-Link devices) is the only necessary requirement. Otherwise, upload the OpenWrt image via the TP-Link GUI.

  1. Configure a static IP connection to the device over the PoE port. The device IP is
  2. Turn on SSH in the management options for the TP-link web GUI.
  3. SSH to the device and run:
    cliclientd stopcs
  4. Upload the OpenWrt …squashfs-factory.bin binary to the firmware update page on the TP-link web GUI.
  5. Reconfigure your static IP to talk to OpenWrt on (the OpenWrt default).
  1. Solder TTL header. Pinout: 1: TX, 2: RX, 3: GND, 4: VCC, with pin 1 closest to ETH1. Baud rate 115200
  2. Interrupt boot process by holding a key during boot
  3. Boot the OpenWrt initramfs
      # tftpboot 0x84000000 openwrt-ramips-mt7621-tplink_eap615-wall-v1-initramfs-kernel.bin
      # bootm
  4. Copy openwrt-ramips-mt7621-tplink_eap615-wall-v1-squashfs-sysupgrade.bin to /tmp and use sysupgrade to install it

The device has four switch ports. See the Photos section below for images.

Port Switch Port
ETH0 (PoE-in) lan0
ETH1 lan1
ETH2 lan2
ETH3 (PoE-out) lan3

Because this device is only supported by newer versions of OpenWrt, you need to use the newer DSA-based VLAN switch_configuration if you plan to use VLANs. For example:

# Setup a bridge (switch) for all 4 ports:
config device
        option name 'br-router'
        option type 'bridge'
        list ports 'lan0'
        list ports 'lan1'
        list ports 'lan3'
        list ports 'lan4'
        option vlan_filtering '1'

# Setup an internal VLAN for talking to the router on the default (untagged) VLAN:
config bridge-vlan
        option device 'br-router'
        option vlan '2'
        list ports 'lan0:u'
# Get a DHCP address for the WAP from the router:
config interface 'router'
        option device 'br-router.2'
        option proto 'dhcp'

# Setup a VLAN 3 for an SSID:
config bridge-vlan
        option device 'br-router'
        option vlan '3'
        list ports 'lan0:t'

# Setup the interface for the SSID, DHCP provided by the router:
config interface 'wifi'
        option device 'br-router.3'
        option proto 'none'

The radios support WiFi 6. That requires a newer htmode (not yet documented on the wiki) to enable. For example:

config wifi-device 'radio0'
        option type 'mac80211'
        option path '1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0'
        option channel '1'
        option band '2g'
        option htmode 'HE20'
        option country US

config wifi-device 'radio1'
        option type 'mac80211'
        option path '1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0+1'
        option channel '36'
        option band '5g'
        option htmode 'HE80'
        option country US

The htmode uses the new HE prefix. HE20 indicates a 20MHz channel width. Some channels are not permitted by the hardware without setting the country code. This has been confirmed for devices sold and used in the USA.
