Hardware HELP Switch doesn't connect to internet anymore

[Dmafra]

Check the encryption method on your wireless security. Nintendo likes TKIP and apparently hates AES. I had to switch the encryption before my Switch could connect - it's lousy because the PS4 seems to hate TKIP and has shoddy connection, so now I had to buy an ethernet cable to connect the PS4 and still have my Switch connect to my router.

The switch doesn't recognize tkip!
With aes the connection appears but not connect with the router!

Oops, I had it switched around. Either way, looks like you've got that figured out, was worth a shot.

Do you know if it even connects to another router or is it a general problem?
Have you tried tethering from your smartphone and trying to connect to it?
Does it work? Can you connect to the internet this way?

Try resetting the internet connection on your Switch and restart the Switch if necessary, if it doesn't connect.

The problem could be related with the router!
I can connect with another routers, even with android.

I had this issue and it kept telling me to update. All i had to do was power off the switch, not sleep mode but fully off. After i turned it back on i was able to install update and connect

When I save the connection even if it's doesn't connect and back to Home menu, after some minutes it's work!

One of your errors is the same code they are giving 3DS who have been banned. If your ID as ever been used on a hack 3DS that just got banned, it may be the cause. Even if you don't have the 3DS anymore, I don't think it matters. Nintendo probably has a list of IDs and it most likely list any systems your ID has been used on.

i don think so, because i can connect in other wifi routers without a problem, My house router works perfect the before the upgrade, but now...

That's the error I had in May. Power off and on or restart the Switch. It will then probably ask you to install an update. You can in most cases select no to it and the net connection should start working again.

 

[Bladexdsl]

i had to reset the stupid fucking thing THREE times before it finally worked again

Problem solved!
Change another router!
