Why is Wi-Fi randomly graying out/ loosing signal?

Hello there,

recently bought second-hand iPhone 7 with beat up case and cracked screen.

It has been updated to iOs 13.5 with fresh reset, and when trying to connect to Wi-fi it shows routers, and can be connected, but after a few seconds it drops connection, and hides all routers. After re-enabling it, it shows again - can be connected for few seconds - and drops connections. So for a while, till ‘settings‘ app glitches out and wi-fi toggle becomes ‘grayed-out‘, cannot be enabled. BT toggle is switchable but cannot find devices/ connect. But never ‘grays-out‘. Priveous owner says before update it was okey (doubt that, but ok, may be).

I tried ‘airplane mode‘, restart, restart network settings, but nothing.

BUT - after making hard-reset, till it goes to ‘Hello‘ screen, wi-fi toggle comes back and connections can be made - but as mentioned above - few times drops out - glitch - ‘grayed out‘. And so on, on loop.

Before screen comes and i try to open it up - it may be antena what is acting up, software issue or it is not fully separated wifi chip (gray one) what everyone suggests to reball or fix pads?

If latter, i shall sell it, as I have not got equipment to do the job - but as I searched - for this toggle is always peramentaly ‘grayed out‘. So there may be hope.

Any suggestions?

Thanks.

Greyed out Wi-Fi is defiantly a problem with the Wi-Fi chip or the big audio IC. On a working phone you can remove all the Wi-Fi antennas and it still will not be greyed out so you can rule out antenna problem.

If you don’t want to get it repaired you could try and put a thin piece of packing under the Wi-Fi chip so it has a little more pressure on it. Sometimes this can get a couple of month’s usage before it completely fails.

Yes, but it is NOT grayed out all the time, that's the issue. But as I understand it only grays out when chip seperates, therefore - there is my problem! I want it repaired, but repair would cost almost the same as phone here. Ok, will try that presure fix for when new screen comes. Thanks.

It might be because of the Loop Disease defect with some iPhone 7’s. You can look at this video about it from Hugh Jeffreys: https://www.youtube.com/watch?v=bguTwD6K...

Nop, has no problem with booting and/ or audio. Only Wifi/BT does not work correctly. But thanks. Will try to write to Apple, maybe they can change to new or refurbished one. Small chance, but worth a try!
