802.11ac 5Ghz wifi AP in RPI 3 B+ #2619
And this the hostapd -dd result:
@urrohitsw if you run
@hamedafra try changing your country to US, it should work with your config, here is my config that does work:
@JamesH65 can we have this looked at?
while it does work with US countrycode? Is this a bug? The frequencies (channels) used in the config I posted are allowed in ETSI zone and do not overlap with DFS channels.
Where does regulatory info for brcmfmac comes from? It certainly is not using crda, is it embedded in the brcmfmac firmware blob?
We are all a bit busy on other stuff at the moment, with numerous people on holiday, so no promises on timescales.
@JamesH65 no hurries, I just wanted to make sure that you are aware of this issue and that it will be looked at. Google provides no clues about AC AP on pi3b+/brmcfmac. The only way that I was able to make it work in AC AP mode was by using US countrycode.
Yes, wifi is a nighmare, 80211n (and friends) is very loose standard which allows the vendors to do funky stuff, non standard extensions and a large etc, been there, hate that.
I had an issue with AP too in the RPI3 B+ with the latest tagged kernel 4.14.71. And setting country_code=US explicitly seems to be better now.
See also here for more info what I saw in dmesg: https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=225414&p=1384182#p1384182
I have the same problem. Kernel 4.14.71-v7+
I can get "n" working in 5Ghz with the country_code=GB but not "ac".
and in the 5Ghz range I can see:
Which is why I can get "n" but not "ac".
I've tried setting this to 0:
It didn't make any difference. Then I realised the double negative of roamoff and it should be switched off so I removed the line and restored the default. Would really like to be able the AP as "ac" with country set to GB - want to use the AP's at a school, putting one in each classroom - and possibly add cameras, temperature sensors etc etc.
Still can't get 802.11ac mode working
Log of hostapd start
Xiaomi Redmi 5 Plus and nettop with Intel Wireless-AC 7265 tells me that connection speed is only 150 Mbps instead of 300. Any ideas?
UPD: my fault: Xiaomi Redmi 5 Plus doesn't support 802.11ac mode. NetworkManager on my nettop shows that connection speed is 433 MB/s, while nmcli shows only 135 MB/s. How can I check which mode is actually used?
Hi guys, I can confirm that @asavah was right, I copied (Ctrl+C and Ctrl+V) his/her config and it works absolutely. I had the problem that the bandwith was too slow but when I had tried to set up 5G Wi-Fi it didn't appear at all.
So, once I rebooted my Pi 3 B+ I did a speed test and now it reaches 60Mb and before only 10Mb
So many thanks @asavah
I am able to get my hostapd on my RPi 3 B+ to work with 802.11n.
However, I am running into trouble trying to get 802.11ac working on it.
And got the expected list of the channels from 1-11, 36-48, and 149-165 (additional channels were listed as "disabled")
I'm running Raspbian Buster:
