Devolo WiFi pro 1750e / EDIMAX Pro WAP1750 / Acelink EW-7679WAC


#1

Hello everybody,

I bought a devolo WiFi pro 1750e Access Point which uses the same hardware as the EDIMAX Pro WAP1750. Does anybody know if there is a package with the latest openwrt available? Then you log into the AP via ssh you get an message that it uses openwrt 15.05.1.Anmerkung%202018-11-18%20101940

Edit: After doing some research, I found the original OEM for this piece of Hardware. The Specs can be found under (http://www.acelink.com.tw/EW-7679WAC.html)

Thank you for your answers,

Sascha

Hello Sascha,
I ported the 1750e to the ath79 target. But that means that you can only use it with the git master branch and you have to compile it yourself. I plan to submit the patch after a little more testing, but I can send it to you before.
Regards,
Peter

Hello Peter,

thank you for your offer. I read some about the ath79 target and I will wait until there is a precompiled image for the 1750e.

Regards,
Sascha

I tried to find out some details about the installed openwrt. I still think it is a great piece of hardware, it is sold for around 50 Euros here in Germany.

Hi all,

I also have a Devolo WiFi pro 1750e and would like to put OpenWrt on it. As Sashca said, great hardware for the price (I have two DAP-2695s that cost triple the price for the same hardware and plan to use this device as a bridge).

I see the 1750c is available as a snapshot:

https://openwrt.org/toh/hwdata/devolo/devolo_wifi_pro_1750c

Given the hardware is now rather mature, would that snapshot or another platform from ar71xx of stable, function?

I'm not really after cutting edge features but if there is no other options, I'd be happy to help test the ath79 target patch for this device.

Kind Regards,
Django


#6

Hello again,

I did some research how much the original firmware from the 1750e differs from the 1750c.

I downloaded both original delos firmware images, extracted the bin files with 7-Zip and did a folder compare with WinMerge.

And guess what, most of the firmware is identical. The most diffs are in some textfiles (1750c / 1750e).

To get back to the 1750c snapshot, I would say with minimal changes you can use the 1750c snapshot on the 1750e hardware.

change my mind

Regards,
Sascha


#7

Hey there,
I already sent the patch to Django, but I paste it here now, too. Hoping that someone has some time to test it and/or port it to share the code with the new qca9558_devolo_dvl1xxx.dtsi of the master branch.
Regards, Peter

Hi all,

I've managed to import and push Peter's patch using quilt to the root of git Master (commit eb1887be93a765b4b86ecad14dd72a5a72d6870e) and compile up a sysupgrade.bin. Many thanks Peter for your time and effort creating the .dtsi device tree.

@Sacha, It only took me about an hour to create a Debian VM, install the build system, patch and compile a firmware bin. I'd be happy to send you my firmware once I've tested it, I'm still waiting for my device to be delivered.

Regards,
Django


#9

Hi again,

I forgot to mention I noticed one minor difference between Peter's patch and qca9558_devolo_dvl1xxx.dtsi when scanning through it, Energy Efficient Ethernet was disable in the latter via:

at803x-disable-smarteee

Something to keep an eye on if we experience any Ethernet link down/up issues.

Regards,
Django


#10

Just a quick update, I flashed my compiled firmware, everything seemed to go fine but it's no longer booting:

root@devolo-331:/tmp# sysupgrade -n -F /tmp/openwrt-ath79-generic-devolo_dvl-1750e-squashfs-sysupgrade.bin 
Image doesn't have a checksum.
Image check 'platform_check_image' failed but --force given - will update anyway!
killall: watchdog: no process killed
Sending TERM to remaining processes ... uhttpd udhcpc avahi-autoipd avahi-autoipd dnsmasq 
The semaphore timeout period has expired.

Looks like everything went to plan but no joy. Maybe I bricked it not waiting long enough for the firmware to flash or there was something I missed in my config.seed? Currently the blue led activates for around 5 seconds before going dark and a power cycle is required.

Anyway, I've been attempting trial and error recover via TFTP over Ethernet and USB (my serial to RJ45 is broken, I've got one on order so hopefully that will shed more light on the problem).

If anyone can provide any insight into the recovery procedure for this device, it would be greatly appreciated.

Regards,
Django

UPDATE: Never mind, the flash did work I've just been using LAN 1 (poe), instead of LAN2 to access the machine it came up with the default IP: 192.168.1.1


#11

Hi Django,
not sure if I got you right. Did you manage to make it work now? Recovery is easy via tftp and flashing from the bootloader, but you have to use the internal uart interface to get access to the bootloader (see attached image for the connections). The external RJ45 is not working and AFAIK the QCA9558 has only one uart anyway. So I guess the external serial interface is realized via some bit banging pseudo uart, but only on the EDIMAX devices, the devolo does not support it.
Regards, Peter

devolo


#12

Hi Peter,

Thanks for the info regarding the serial port, good to know for any future flashing attempts.

I've got it all working now:

devolo

Many thanks for your patch, it saved me a lot of time and effort. Unfortunately my problem was a simple as using the wrong LAN port. Live and learn :slight_smile:

The AP performs great as a bridge (relayd) with the stock ath10k-firmware-qca988x. I get a solid 26-29MB/s at an idle signal/noise of 55dBm/102dBm respectively. Did notice that any activity in the control panel would bring this down by 10MB/s though but not a problem for myself as I won't be using it very often.

Given the dipole antenna are apparently only 2dBi gain, I tried some higher gain 10dBi directional antenna's I had lying around but they reduced the signal. Probably because I couldn't direct them given the AP is attached to a wall and behind a TV. I've got some other omni high gain antenna's but I can't find them :-/

If anyone would like a copy of the firmware I compiled up, until we get an official snapshot, let me know.

I had a look at creating a wiki entry for this device but after creating an account it doesn't seem I can add a page. Any idea who we talk to about that?

Regards,
Django


#13

Great to hear that you did manage to get openwrt up and running. Did you encounter any problems?

Regards,
Sascha


#14

Hi Sascha,

No problems other than using the wrong port and the performance drop when using the control panel but that might be a limitation of the 720Mhz CPU.

I had about 24hour problem free uptime before I did a restart to test the directional antennas, so far so good.

Regards,
Django


#15

Hi django,

I would like to test your compiled firmware. I can provide some space on my nextcloud instance.

Regards,
Sascha


#16

Sent you it. Let me know how you get on :slight_smile:

Regards, Django


#17

What exactly do you want to do?

Create a dataentry page?
Create a device page?


#18

Hi tmomas,

Create the techdata page to start with:

https://openwrt.org/toh/hwdata/devolo/devolo_wifi_pro_1750e

And add it to https://openwrt.org/toh/hwdata/devolo/start

Many Thanks,
Django


#19

You should now be able to create a new dataentry via https://openwrt.org/meta/create_new_dataentry_page

Has the patch already been sent to the mailing list, or has a PR been created?


#20

Hi django,

I got the firmware up and running. I will let you know if I encounter any problems.
