This isn't strictly "homelab" related, but I'm not sure if there's a better community to post it.

I'm curious what kind of real-world speeds everyone is getting over their wireless network. I was testing tonight, and I'm getting a max of 250Mbit down/up on my laptop. I have 4 Unifi APs, each set to 802.11ac/80Mhz, and my laptop supports 2x2 MIMO. Testing on my phone (Galaxy S23) gives basically the exact same result.

The radio spectrum around me is ideal for WiFi; on 5Ghz, there is no AP in close enough range for me to detect. With an 80Mhz channel width, I can space all 4 of my APs so that there's no interference (using a non-DFS channel for testing, btw).

Am I wasting my time trying to chase higher speeds with my current setup? What kind of speeds are you getting on your WiFi network?

If I'm like 5 feet from the AP I'll see about 600Mbps on 2x2 802.11AC, that's about as good as it's going to get because the link speed is only 866Mbps, and you're never going to get close to that with actual transfer speeds due to overhead.

Speed drops off very rapidly with range on 5GHz, so across the room it'll be down to 300Mbps or so already.

I testing this after reading your comment. A few feet away from one of my APs, I got about 550 down, 650 up. 15 feet away through a single wall, I get 250. I had no idea a 5Ghz signal falls of that quickly.

Yeah it's wild, the larger the channel width in use the faster it drops off too.

6GHz Wifi is even shorter range!
