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


Dual band 2.4 and 5 GHz WiFi (3 by 3 IEEE 802.11n 450Mbps, 3 by3 IEEE 802.11ac 1299Mpbs)

\begin{itemize}
\item 2x 1Gbit ethernet ports (with Power over Ethernet support)
\item 1x USB 2.0 port
\item External serial console port (Currently unsupported but internal 4-pin internal Dupont connector is functional)
\item 1x GPIO attached piezo beeper
\end{itemize}

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.




\subsection{Flashing Openwrt on to the WAP1750}

At the moment, this page:
\\
https://openwrt.org/toh/devolo/devolo\_wifi\_pro\_1750e
discusses flashing new firmware via SSH. However, the WAP1750 has a custom console, and while it's running GPLv2 GNU Linux, somehow it managed to lock down the software, so that simply shelling into it, is no longer possible. I'm sure that is a sin. GPLv2 does not mean people can take it and then abuse it for commercial use. It's a community good. 

None the less, it can be turned into an upgradeable router via the following means:
\begin{itemize}
\item Teardown enclosure
\item Remove flash chip by desoldering with hot air
\item Read flash with appropriate tool (Flashrom, TL866A).
\item Patch existing image sysupgrade for Devolo 1700 series.
\item Write flash with new image
\item Resolder chip to board
\item Access board via FTDI / USB-Serial chip
\end{itemize}
Simple enough, right? It is simple. But it's not simple. At least 5 years of hobbyist electronics and I'm able to do this, but for the layman... Only with a guide. And let's also talk about the issues that arose during the above steps. It's never as easy as it should be.
