I bought a 3-pack Deco M5 back in 2019, and they've been running great with no problems at all. I tried upgrading to Deco X60 a couple of years ago but had real headaches (physical symptoms), so I stayed with the M5, which has been headache-free for me and my wife.

Now I've moved to a new townhouse with three floors, and I thought to add more M5's to cover the additional areas. So, I bought another 3-pack Deco M5 on Amazon but started experiencing headaches the moment I started them up. This is similar to what I experienced with Deco X60.

I noticed these new ones are different. The ones I got back in 2019 are V2, and the new ones are V3.2. So I guess the new M5 v3.2 has a stronger signal similar to the X60, which gives me a headache when they start blasting WiFi signals.

This issue isn't just theoretical - it's real and is affecting my ability to concentrate. I work from home, so I can't have this headache going on. I'm thinking of ditching the M5 v3.2 and considering a 3-pack Deco M4, as it's supposed to be "weaker" in terms of signal strength.

But on the M4 Support page, it lists four different hardware versions: V1-V4, and I'm sure if I buy them now, I will get the new V4. Are the M4 v4 similar in signal strength to the M5 v3.2? At this moment, I don't know what to do. Any advice is greatly appreciated.
