My Deco XE75 Pro mesh system has been running for about a year. All the units are connected to the wired router/switch through ethernet cables. Both 2.4G/5G and 6G Wifi channels are turned on. However, I noticed the 6G WIFI is always problematic. The iPhone 17 reports the 6G WIFI is not compatible. However, it can still connect to the 6G WIFI. The other andriod devices won't report any errors/warnings. However, all the devices connected to the 6G WIFI experience unstable connection problems. The web apps, YouTube, TikTok and so on, will freeze every couple of minutes. As soon as I switched all the devices to connect to the 5G WIFI, all the apps are running perfect now. Apparently, it's not the internet connection's problem. It's the 6GHz WIFI on the Deco not stable. I always keep the firmware on the Deco to be up-to-date.

Anyone experience the same issue?

Thanks,

Leo
