After months of struggling with some really bad disconnects on a pair of Asus RT-AX92U routers, I've finally landed on a combination of things that work for me. The reason I titled this "brainstorming" is because I'm not sure WHY one of the fixes worked, and figured maybe others might have input they'd want to add.

First, the issue - casting any audio from my phone to more than one Google Home device was a nightmare. Cut outs, complete drops, desyncing with my phone - you name it.

I'll skip most the fixes I've tried, because there have been many. Namely, a whole bevy of wireless settings, turning off any type of roaming on my Google Home devices between my two routers, downgrading firmware to 384 from 386 (as suggested by someone on a forum), and a whole bunch of other stuff.

What finally seems to have fixed the issue on my network are two things, specifically.

First, I disabled auto on wifi control channel. I'd switched to this a few months back thinking maybe my issue was interference from nearby homes. We're SATURATED with 2.4ghz wireless in my neighborhood. I disabled this, walked around my entire house with a Wifi diagnosis device, and came up with a channel that seems to be far enough away from the strongest interference.

Second, and this one is a bit more obscure and I'm not exactly sure WHY it works, but after switching it, I'm suddenly getting a better connection than I've had in months - change the modulation scheme (found in "professional" under wifi on my Asus router), from "Up to MCS9" to "Up to MCS7". From what I've read, MCS9 can cause issues in some devices, and I don't need raw speed on my 2.4ghz network anyway, because it's almost primarily for my smart home stuff.

That's it! That's all I've done, and I've gotten through two entire podcasts with no disconnects at all. Doesn't sound like much, but this is the first time in months I've had that joy.

Feel free to drop tips here if you've got them as well, I just wanted to share my experiences in case anyone else was desperate.
