I have followed this guide to configure my TP-Link Archer C7 running OpenWrt 19.07.4 r11208-ce6496d796 as a dumb AP, and everything works great...almost.
The only issue I'm experiencing is that my house's power will cut off every hour or so, after an electrical leakage is seemingly detected by my GFCI/RCD/safety switch (it's called the latter here in Australia, but can also have either of the other two names according to what I've read).
This started happening after connecting the Archer C7 to an old TP-Link TL-SG1008D v5.1 switch, and connecting that to an Apple TV 4K.
What I'd really like to eventually achieve is something like the following network diagram:
Where the lines represent ethernet cables and the other three devices connect wirelessly.
Is this something that my current setup of the switch and routers can support? If not, how can I fix things? And what's the deal with the safety switch continually getting tripped?
If your RCD is tripping one of the devices has a bad power supply, leaking 240v to ground.
That is a major issue and you should take all 3 out of use until you can identify or replace the faulty power supply.
It could also be bad wiring in the power points but as it started occurring when you put these devices in service that seems unlikely? Have you used the power points they are connected to before?
While not relevant to your RCD issue (which needs to be sorted first), 19.07.4 has been EOL for years and contains unfixed security issues - upgrade it to 23.05.2, now (the c7 has no problems with running current releases, no need to stick to old and unsupported ones).
Thanks, I suspected as much. I've taken your advice and unplugged not just those three devices, but everything in the house and the RCD still keeps tripping immediately when I try to flip its switch
I've called an electrician as something is obviously seriously wrong here...and me continually fiddling with things in an attempt to diagnose the problem myself is seemingly making it worse.
Last night when this started happening, I could at least get power restored by simply unplugging the suspected problem devices, but now I can't...and stuff in my fridge and freezer is slowly going bad while I fumble around.
Yep, upgrading OpenWrt is what I was trying to do when all of this started happening I'll start another thread about the issues I'm having with that when I get the more important RCD issue fixed.
A GFCI itself is not super reliable and they can fail all different ways including developing a "hair trigger" to false trip, which usually degrades into never staying on when reset.
Phew, that's great to hear and is hopefully what's happening here, in which case I assume the electrician can replace it when he gets here and that will fix everything?
Good, you need a sparky to make sure your place safe.
Way off topic - but an item that can trip RCDs repeatedly are shorted air conditioners, particularly at this time of year in Aust. Isolate your aircon at its external cut off switch and you may find the RCD stops tripping.
Hmm yeah, we did have not just one but two air conditioners running when the problems all started, plus a washing machine that the sparky identified as the main culprit.
He tested its power lead with a non-contact tester (didn't even know those existed; very cool! Going to have to get myself one) and determined that it was shorting somewhere within its circuitry.
He also upgraded our ancient, single RCD into two modern ones that cover the same two circuits that the old one was handling by itself - how was that ever considered safe?!
Anyway, everything seems fine now. I'm yet to work up the courage or patience to really stress the system enough to fully test that everything works well and safely, but .
Thanks everyone for the kind responses even though this whole forum is about OpenWrt, and my issue wasn't really related to it at all! It's nice to know that some people care enough about strangers that they're willing to take time out of their busy lives to help out a noob like me lol
P.S. Just as a brief aside, @jdwl1o1 do you happen to be an Australian yourself? I've never heard anyone else call an electrician a sparky, so if you are, it's great to see a fellow Aussie on here!
