Bunch of old thermostats. Should really change them out but....

@JonathanLee what is that a printer right next to it.. Those are great for amplification of wifi ;)

Especially when their wifi is on ;)

JonathanLee

@johnpoz it's a printer. . . Oops

JonathanLee

ifconfig ath0_wlan0 txpower 40

this is the command to get out of 17% transmit power

johnpoz

@JonathanLee and users wonder why their wifi is problematic.. hahaha

I found the best settings was wifi 802.11na and using -40 channel widths. It performs better than my apple airport Extreme. Whats weird is others in our area use 80 for channel widths on the 5ghz. My performance now with the 2100 is unreal. I didn't think it could do it. Movies streaming in a 3 bedroom house on different devices Xbox Nintendo switch etc iPad. It's running snort on wan and lan with AppID, squid and squid guard. I had to disable Clam AV to get my memory use down to 20-30 percent utilization. It is unreal it could be better than consumer grade equipment from that timeline now. It needed 802.11na not ng. Keep in mind my airport only ran wpa2 and with aes encryption options that thing was from 2009. I think the card dates to 2015 ish.

@JonathanLee Weird, but whatever works. With ng I get a -40db signal, with na I get -70.

5Ghz is more easily attenuated by anything.

@johnpoz
It is the same upstream.

@JonathanLee Is this the Compex or the Apple card? I have the Compex and my txpower was set at 30 by pfSense. Also, the "txpower 40" argument seems to have no effect, stays at 30 for me.
Maybe that's because you're using na and not ng. EDIT - Yeah, that's it.

@provels Take a look at this file with the built in editor in pfsense GUI

This may have blocked you from turning it up. It might be limited by way of this file. . .

Scroll down and find WiFi 11g and check for something called max power
