This ports device support for the old v1 versions of TL-WA850RE and TL-WA860RE from ar71xx.

This is done based on code only, I do not own the devices. Please test, but be aware of the risks explained below.

Based on the reports by @Gingernut1978 and on the dmesg, it seems that eth0 is not coming up properly.

WA850RE has been merged, and network setup for WA860RE is the same. So, risk for bricking should be lower now.

Nevertheless, make sure you have WiFi enabled by default for testing, or you risk locking you out of the device. Any hints welcome on what's wrong with the network setup.

Current development state is available at: https://git.openwrt.org/?p=openwrt/staging/adrian.git;a=shortlog;h=refs/heads/rft-devices-ath79

Those devices are ugly for several reasons:

  • 4/32
  • integrated power supply
  • hard to open
  • no "easy" TFTP

So, bricking the device will cause more pain than usual on these devices.

I will keep this open for about a month in case someone is interested.

I have a TL-WA850RE v1 and will be testing this asap, will comment the results.

@Gingernut1978 Thanks, but be aware that there is a chance that you will brick your device.
An easy precaution could be to enable WiFi by default for testing.

@adrianschmutzler Just updated from ar71xx to ath79 after applying your PR and keeping current configuration. Seems to be working very nicely.

Thx

@Gingernut1978 Thanks.

  • LEDs working?
  • Can you connect to AP?
  • Traffic in both directions via WiFi and ethernet?
  • Correct MAC address for WiFi and eth0?

If your insterested/willing to work on porting, I also have a Belkin AC1750DB ar71xx device I can test.

I did the recent PRs because support for those devices were missing in our local Freifunk (downstream) project and they were relatively easy (and thus quick to do). My motivation to migrate further devices I do not own myself is limited. But with the big pile of migrated devices that can be used as blueprint it should be too hard for other developers to add PRs for further devices ;-)

LEDs work
Can connect to AP
MAC address are same for WiFi and eth0 (same as printed label)
Detected but no traffic over ethernet, WiFi seems fine.

I'm an idiot and did a device reset, now I'm locked out. Will get back to you if I get it working again.

Thx

Based on the reports by @Gingernut1978 and on the dmesg, it seems that eth0 is not coming up properly (but everything else is fine on the WA850RE). Make sure you have WiFi enabled by default for testing, or you risk locking you out of the device. Any hints welcome on what's wrong with the network setup...
