iPad Pro Strange Wifi 6 issue

[Qutrit]

Hello!

I’m having an issue where when ine of my two macs is online through wifi, my wifi 6 throughout on my iPad Pro (2023) goes from full 2gb/s to less than 200 Mb/s. I have no idea why it happens and it only affects wifi 6. Anybody has any clue what could be provoking this? The macs re older models and don’t use wifi 6 at all. Nothing else is using the bandwidth. Just turning them on on wifi does it.

thanks for any help in advance

Are you are talking about WiFi 6 or 6E?

Which WiFi router are you using? What is your Internet modem provider/bandwidth?

 

[Qutrit]

Wifi 6E, 1.5Gb/s provider and ZenWiFi Pro ET12

Do you have a combined SSID on the Asus (2.4, 5 and 6 Ghz) or separate SSIDS for each frequency?

You are getting 2 Gbs from a 1.5 Gbs provider?

 

[Qutrit]

Combined SSID. However I do check in the router that the iPad is connected to 6E. Yes I got 2gb almost from the beginning (not gonna complain about that, they do give more bandwidth than I contracted)

The very strange thing is that it’s only when the macs are online that the throughput drops so much. This has been tested reliably.

I'm guessing it defaults to the protocol of the old macs or the slowest speed or something like that
I have seen something similar with mesh and when you use some hardware that's a lot slower they all have to be a lot slower. Powerline adapters do the same thing.

Yes, I think that's it. You can have 2x gigabyte powerline adaptors and if you have an old one that runs at 200 they all run at 200 and I also found this about when you connect mixed protocols:
802.11g allows 54 Mbps maximum theoretical data rate, while 802.11n can go up to 600 Mbps and 802.11ac maxes out at 6,900 Mbps theoretical speeds in the 5 GHz band (1,300 Mbps on 2.4 GHz).

Thanks! this possible explanation definitely matches up the the experience I have. these two computers are older devices and all new stuff connected to 5g does not interfere at all with the iPad wifi 6E speeds

Combined SSID

Can you separate the SSIDs? I have one combined SSID which I can't separate that intermittently connects to the wrong frequency.

If your router is slowing everything down when the slower devices are connected I'd contact Asus support. I have maybe 32 devices connected to my network using all 3 frequencies and don't see any interaction slowdowns on my Netgear (not mesh) router.

Same here. I'm using Xfinity's xFi Gateway modem/router.
