Ethernet cables don't speed up or make your Wifi connection better if that's what your asking. Ensure the set up is directly plugged into your Router for stability.

If that wasn't it, have you tried using your devices on ethernet ONLY settings instead of Wifi? If the cables work, but NOT in the console, then there's a chance your console could have damage to that port. Or wrong settings. Check Router supports that.

Test the cables in a pc or laptop without wireless wifi setting. Wifi should be turned off on system to force computer to connect ONLY with ethernet. Easy test. In Network setting just select connection over ethernet.

ty for your feedback @lucifer_sol, but i already figured out that there is os limitations by nintendo themselves, to make more sales with their adapters they locked them within one chipset that they're were using in theirs adapters

there was made patch by jan-hofmier on github, to support more revisions of AX88772 chipsets, but i'm out of range because all of my adapters i bought is still unsuported even by this patch
