23.7 Legacy Series / Re: Slower speeds over WIFI AP (Netgear WAX214v2)
« on: September 24, 2023, 02:08:50 pm »It depends on your access point and on your phone.
Theoretically for 802.11ac connection between phone and access point, when both access point and phone have 1 antenna:
- 433 Mbps per spatial stream on a 80 MHz channel with 256-QAM.
- You can easily reduce 30-40% from that theoretical level and then you come to the real world performance of around ~300 Mbps.
Theoretically for 802.11ax connection between phone and access point, when both access point and phone have 1 antenna:
- 600 Mbps per spatial stream on an 80 MHz channel with 1024-QAM
- Reducing that by around 30-40% from that theoretical level and then you come to the real world performance of around ~400 Mbps.
The only way to get more speed is if your access point AND your phone have multiple antennas, so for example both sport MU-MIMO-2x2.
Then the access point and the phone could have 2 parallel spatial streams at the same time, doubling the speed to a real world performance:
- 802.11ac to around ~600Mbps
- 802.11ax to around ~800Mbps
Example from personal experience:
Im using Zyxel NWA210AX accesspoints, and in my PCs are Asus-PCE-AX3000 cards. Both have MU-MIMO with 2 antennas for 802.11ax and with iperf of speedtests I get around 750-800Mbps real world performance.
Sorry, I had the wrong topology, the PC via LAN isn't there anymore and the Mobile Phone is essentially my PC now. I have an Intel AX200 Wifi Card that handles 802.11ax and according the spec sheet, so does this Netgear.

I appreciate the help though, still learned something about the 802 bands which I never knew. Its definitely something I've configured wrong and seems like its probably more a Netgear thing so I might try their forums.
This issue has nothing to do with OPNSense. Everything you described clearly points to access point issue/missconfiguration. You need to check your AP settings. Are you connecting via 2.4Ghz or 5Ghz wifi? How are your wifi channels configured and how many SSID`s are in your surrounding area. What are the wifi connection capabilities of your wifi clients. There are so many factors that can cause the issue you are seeing.
I answered some of these in my post but appreciate it was a long one, but just to reconfirm:
- I made sure I was on 5Ghz
- There's a lot of noise here (apartment building), but made sure I was on a quiet channel and scanned to make sure this was the case
Ta!
