devolo WiFi pro 1750e

The devolo WiFi pro 1750e is a wall mountable access point with:

Dual band 2.4 and 5 GHz WiFi (3×3 IEEE 802.11n 450Mbps, 3×3 IEEE 802.11ac 1299Mpbs)
2x 1Gbit ethernet ports (with Power over Ethernet support)
1x USB 2.0 port
External serial console port (Currently unsupported but internal 4-pin internal Dupont connector is functional)
1x GPIO attached piezo beeper

The access point is manufactured by OEM Acelink Technologies Co., Ltd. as a EW-7679WAC and was originally sold by Edimax as a WAP1750. The Edimax unit was reviewed by SmallNetBuilder.

→ Install OpenWrt (generic explanation)

Set a password for the root user as prompted on first set-up of OEM firmware.

Upload OpenWrt sysupgrade image via SSH to the device. Use /tmp as the destination folder on the device. User is root, password previously set in the web interface.

Install OpenWrt with:

sysupgrade -n -F /tmp/<openwrt-image-name>

Connect to LAN 2 (poe)

It's not currently known if this device supports OEM flashing via tftp

→ generic.sysupgrade

Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
Upload image file for sysupgrade to LuCI
Wait for reboot

If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading:

sysupgrade
mtd

Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

sysupgrade

Login as root via SSH on 192.168.1.1, then enter the following commands:

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

mtd

If sysupgrade does not support this router, use mtd.

Login as root via SSH on 192.168.1.1, then enter the following commands:

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

→ generic.debrick

→ failsafe_and_factory_reset

→ Basic configuration After flashing, proceed with this.

Set up your Internet connection, configure wireless, configure USB port, etc.

The default network configuration is:

Interface Name	Description	Default configuration

The Devolo WiFi pro 1750e has the following buttons:

BUTTON	Event
Reset	reset
WPS	wps
USB Eject	usb_eject

The Devolo WiFi pro 1750e has the following LEDs:

LED	Trigger	sysfs name
Blue	booting, running	dvl1750e:blue:status
Red	failsafe, upgrade	dvl1750e:red:status

The LED behaviour can be altered after flashing (no pun intended ) through the LuCI “System” → “LED Configuration” page and by selecting an appropriate Trigger, for example “Network device activity (netdev)”.

Patches for this device can be found at Patchwork
A thread discussing this device can be found at Forum Post
This AP has been tested to work with both the ath10k-firmware-qca988x (QCA) and ath10k-firmware-qca988x-ct (Candela Technologies) firmwares and associated ath10k and ath10-ct kernel modules. As of writing (22/01/2019), snapshots default to the Candela Technologies variant (1) but performance is more consistent (2) and faster (3) with the QCA variant.
The TX Rate shows incorrectly as 6.0 Mbit/s when using ath10k/ath10k-firmware-qca988x. Instead, the current TX Rate can be read from:
```
cat /sys/kernel/debug/ieee80211/phy0/ath10k/fw_stats
```
