FS#2437 - Add algorithm for auto channel selection (ACS) #6114
Comments
clel: Forum post: https://forum.openwrt.org/t/xiaomi-wifi-router-3g-18-06-x-wifi-issues-2-4ghz-5ghz/20169/121?u=clel Suggestion of a fix (might not be the intended way): https://www.programering.com/q/MDMxQzNwATA.html |
stokito: On the wiki https://openwrt.org/docs/guide-user/network/wifi/basic is said that channel “auto” defaults to the lowest available channel. |
stokito: FS#81 similar ticket |
moeller0: In many parts of the world the preferable channel set actually is 1, 5, 9, and 13 (see [[ftp://https://en.wikipedia.org/wiki/List_of_WLAN_channels]]). |
clel: "So if the channel 1 is already taken then OpenWrt will take channel 2 while it's better to take channel 6." I am not sure, wether that is how it currently works. The forum post instead suggests that channel 1 is always taken. The device does not even look, whether there are other routers around using channel 1. "available channel" probably means available on the router itself. That is what I understood, but I might be wrong with this. "Does your solution works like this?" This is not from me, but just what I found when searching for this issue. I thought I might link it, so there is some starting point of a discussion. "In many parts of the world the preferable channel set actually is 1, 5, 9, and 13" Also, if I understood correctly, there is the possibility to use a broader channel width in order to increase the transfer rate? So the router might want to choose that if there are not many occupied channels? Or is that regulated / technically restricted? |
clel:
Apparently OpenWrt currently does not offer an algorithm for auto channel selection of a wireless channel. Instead it just always seems to default to channel 1 if autochannel is activated. This is not the intended behaviour and not what a user expects. So I suggest adding some selection algorithm to it (there is already available at least one, so it should not be too hard to add it).
