Today I received my new R7800. Flashed 18.06.2 on it. Works as expected. Only downside is that the two wifi leds (2.4 and 5 GHz) aren't working. There is no configuration for them in Luci.
I found this post which deals with this topic.
R7800 - No Wi-fi LEDs in OpenWrt 18.06.0-rc2 r7141
However, as I'm a noob, I don't completely understand what the problem is and possible solution.
Is there a simple way to get them working or should i just wait for the next release (18.06.3 or 19.07)?
Have you tried snapshot already instead of 18.06.2?
The LED for ath10k was introduced after the 18.06 branching and has not been backported from master to 18.06. You need to patch the source code and compile OpenWrt.
(or you could flash my R7800 community build, which includes the necessary patch)
The needed patch for 18.06 that patches several source code files is:

Or alternatively you can follow the alternative advice from me found in the other thread that you referenced. But also that requires patching and compiling.
Since Jack calls himself a noob, I think this would be the easiest solution for him.
@tmomas and @hnyman; thanks for your suggestions but as i stated "i'm a noob" on this. Compiling my own build is at this point in time a bridge to far.
I will however try the @hnyman community build.
To upgrade from the current 18.06.2 to 19.07 I would need this file as it is an upgrade?
R7800-owrt1907-r10225-94a1999b4f-20190626-2251-s…s-sysupgrade.bin
If i decided, for what ever reason, to go back to 18.06.2 stable, is that possible?
Please use the 18.06 build for now.
The whole 19.07 is still under initial branch launch...
That is the correct file. "Sysupgrade"
And you can go back to 18.06.2 easily.
