Hostapd won't start in HT40 mode using 8812bu and noscan=1, starts ok if there is no AP's around

[forever_ noob]

There is a patched version that enables noscan=1 , but the one I'm using seems like it hasn't been patched.

When there is no AP's around HT40 kicks in ok without noscan=1.

With noscan=1 and AP's are around hostapd won't even start in HT20 mode.

Any help?

the noscan=1 patch take the AP out of compliance with 802.11

 

simply put - I could fix it, but not inclined to do so...

Providing logs with 

armbianmonitor -u

 significantly raises chances that issue is getting addressed.

Thanks guys!

 

@sfx2000, are you suggesting me to go with hostapd v2.10-devel and it would work?

@Werner, here's the armbianmonitor -u http://ix.io/2x61

In case if it doesn't work, check here: https://github.com/armbian/build/tree/master/packages/extras-buildpkgs/hostapd/debian and build from sources. But its possible that noscan need some code adjustment due to upstream changes: https://w1.fi/cgit/hostap/

@Igor , in a nutshell, to be safe it would work, I have to find source code for the hostapd 2.6, put your patches in that project and compile it? Does that patched hostapd 2.6 already exists so that I can skip all the hassle of compiling I'm not familiar with, like a *.deb file?

No, I think the exact problem is as I describe it, but I don't plan to dig into that anytime soon. You can also later fix our scripts and save us some hassle

I had the same issue after upgrade and I just removed noscan=1 option from hostapd.conf.

BTW, here is the listing from armbianmonitor, if anyone finds it useful: http://ix.io/3xDv
