Finally got around to setting up my pi4 and am having some issues with using AC wifi. I can usually get it to connect but it eventually disconnects reporting “failed - input/output error”.
While it is connected it can’t handle and load without disconnecting into that error state.
When connected to N wifi (2.4GHz) from the same router it runs fine.
Can’t find a lot online, did find one report that a user has similar issues, replaced it and has been smooth sailing since.
Don’t want to jump to the conclusion that it’s hardware at fault though.
Anyone have similar issues or any thoughts?
