Wii U interference

mikematt101 — Tue, 15 Apr 2025 10:38:16 GMT

We are having problems with internet connection when our children are playing on our Wii U. We know that the Wii U controller uses the 5 Ghz frequency and this seems to be interfering with our network. This issue only seems to have started since we installed a BT wi-fi disc, and it seems that only devices connected to the hub via the disc are being affected. Are there any configuration changes we can make to the hub/wifi disc that might resolve this? (I have changed the channel to 48 rather than 36 but this has made no difference) Unfortunately there are no settings we can change on the Wii U.

I’d try 40 and 44 as well.

I’m not particularly familiar with the BT discs but the thought occurs that they may be using 36 for the backhaul and 48 to connect to devices.

Edit: Actually, having re-read your post, I think I’m back-to-front. I seem to recall the discs use 36 for the backhaul and that can’t be changed. The 48 would be the channel it uses to connect to devices, so 40 and 44 would make no difference.

Thanks for your reply. So if the discs are fixed at 36 and that happens to be the channel the Wii U remote uses, there is absolutely nothing we can do to prevent the interference other than ditch the disc?

It looks like, but I will stress again that I am not particularly familiar with these discs, so I could be wrong. There are others on here that know far more about this area than me. I'm sure someone will confirm or refute what I've said.

As far as I can see with a wifi analyser, the disc backhaul follows the same channel as set on the hub for normal broadcast. However, the graph is very weird as it shows the peak at channel 42 regardless of channel selected!

The text shows CH xx (42) where xx is the selected channel

Thanks, however I'm guessing this isn't getting any closer to a solution?

Have you tried all the channels?

@mikematt101

Try a WiFi analyser & see if you can see the Wii controller on that. If so you can compare what channel it's operating on compared to the BT gear.

I believe the 42 indicates it is bonded channels with 42 as the centre. The meter displays looks like 160MHz to me. Strange it should be using that, though.
