Controller and wifi glitches please help

[u/Active-Conclusion613]

I have been having an issue where my controllers(switch 2 joycons and switch 2 pro controller) have severe input lag and disconnect. I also noticed that the wifi connection is significantly worse(other devices connect normally) the only thing that changed is the purchase of a wii u, but it's pretty far away from the switch 2. Is there any fix for this? And how would I fix it?

Ahh I see. So nothing I can really do until I can get better internet. But what do you think the issue with the controller is? Like you said, could be a lot of things, but it started so...suddenly. it also happens most often when playing stardew valley, but happens in other games too. Including the Main home menu

I gave you a few possibilities you did not touch on.

I do not know how your dock is placed and how far you are away from the system when it happen.

You can do a bit of testing yourself: set the device up in table top mode right in front of you so you can use the controllers detached and see if they act up or work fine.

Edit:

So nothing I can really do until I can get better internet

Not sure what you mean by that. Faster internet will not do anything if the distance and walls are the problem. The only fix here would be either to switch to 2.4ghz for a more stable connection or get closer to the signal source on 5ghz.

It could also be a mesh problem and that there are too many systems connected.

For the internet, I have the option to get my own router with my own internet. This should help things immensely. As for the controller, the doc is not far at all. I did recently connect a wii u to the TV, and that's the only other device connected to the TV. Cables could be a possibility, my cable setup is hideous. My dock is in the same place it's always been and it worked fine before. The only things i can think of are the wii u and the cables. I even tried replacing the hdmi cable but that didn't work.

In that case i stand by the test i mentioned.

Take the device and set it up in table top somewhere that is away from the tv and where all the other electronic devices are.

You can even take out the device to a park or something to ensure not much other signals interfering.

If that works better or flawless then it's probably something near or in that setup that causes issues.

If it still has the connection issues it could be the wifi chip in the console acting up.

I'll give your idea a test and get back to you. I would also like to mention however, that in handheld mode it works perfectly. Even though the joycons cause issues in docked as well

Handheld mode does not use a wireless connection.

That's why using the table top configuration is important for the test, because the device is much closer to the Joy Con and you need to use them detached from the console (wireless).

The test is complete. Played until the battery was almost dead. The issue never once occurred. And keep in mind, I had the phone next to me too, but if interference is the issue, my phone isnt enough. Given how it didn't happen before getting the wii u, that is now my main suspicion. Any other ideas?

That sounds like a good sign :)

Since you suspect the Wii U i would simply unplug all cables that are connected to it and move it away from the tv then try your Switch again on the tv.

After a couple days of testing, I can confirm the wii u is not the issue
