the good neighbor occupied the wifi double time than the bad neighbor
Booth models are not perfect. The “be friendly to your neighbor mode” are not realy friendly to your neighbor and the “be unfriendly to your neighbor mode”, are not realy unfriendly to you neighbor. Boot modes look before sending about the channel are free or not by (SMACD?) or what ever.
Some million of routers around me have have disabled the “friendly neighbor mode”. In this invirement, i have to do the same.
WiFi 6 will handle the problems depend on more than one wifi user a little bit better. Depend on existing glinet routers are the wifi not a replacable module like intel 200ax, i need to wait for a model with integratet actual wifi modul.
Ultimately at the end of the day - even “forcing” 40MHz channels in 2.4 doesn’t guarantee that you’ll actually get the bandwidth.
802.11 always has a primary channel - that’s 20MHz - the secondary channels are conditional, so data there needs to pass a clear channel check before you can use the secondary channel(s). If the secondary channel is not clear, it won’t be used, and the PDU transmission will be 20MHz for the duration of that PDU.
the main difference with the no-scan is that it’ll permit 40Mhz, with the caveats above, and no-scan makes autochannel a bit more difficult in crowded areas.
Given the proclivities of 2.4Ghz, setting the bandwidth to 40 will cause problems. Not big problems, but pesky connection-related issues that seem to suddenly appear, only to disappear as quickly! However, if you have 2.4 Ghz set up as a Trunk Pipe, and your users live @ 5.x Ghz above, you’ll be lovin life!
"WLAN coexistence active (2.4 GHz frequency band)
The FRITZ! box can use 20 MHz and 40 MHz channels (according to WLAN-N standard). However, if several WLAN routers in the 2.4 GHz band radio in a 40 MHz channel, interference will occur. To avoid such interference, activate “WLAN coexistence active”. The FRITZ! box then switches to 20 MHz if it detects a WLAN router that is transmitting in the 2.4 GHz band in a 40 MHz channel.
Thank you for a very interesting thread! I’m sure that I am not the only GL-iNET customer patiently waiting for the company to introduce WiFi 6 products. However, I agree that the wait has been rather painful!
So, while we are all waiting with bated breath for GL-iNET to introduce a WiFi 6 router, I certainly agree that, in lieu of WiFi 6 functionality, they should be seriously working on any innovation that can improve WiFi 5 for all of us. This particular innovation by Hilfe Fritz, is not only promising, but actually delivers on the promise in production networks!
Considering the plethora of cave-man, ass-backwards networks I have to deal with on a daily basis, I NEED this, and more, to make my life easier!
The “noscan” feature used by AVM, among others, is a component of older Openwrt firmware, which is only not used by some hardware manufacturers. So there is nothing to reinvent.
Thank you for history lesson. I didn’t use “innovation” in the sense that it was an invention/new technology. Innovation is often used to refer to notable cases where an older technology, technique, or idea is used, reutilized, or repackaged with remarkable results, and help companies remain competitive. Also, for sure, I’m relatively new to the Open Source approach to networking and I thank those, like you, who take the time to help me learn!
Again - hostapd is trying very hard to conform to IEEE guidance in the specs, so forcing 40MHz is contrary to that, it’s the 20/40 HT Coexistence that keeps things calm…
WiFi6 isn’t going to change things with regards to HT/VHT/HE coexistence, as it still needs to support the B/G/N specs and rules set there.
Anyways - OpenWRT is open-source, and so is HostAPD, so patch as needed, and build your own - but I do think it’s a bit unreasonable to ask an OEM to do that, as this does impact their WiFi Alliance certs
