I followed this guide [OpenWrt Wiki] Wi-Fi /etc/config/wireless to configure my router.
In this document, it says:
Name Type Required Default Description hwmode string no (driver default) Selects the wireless protocol to use, possible values are 11b, 11g, and 11a. Note that 11ng and 11na are not available options, see ticket 17541.
I think this description is outdated because it mentioned nothing of 802.11ac and 802.11ax.( I know 802.11ax support is still in SNAPSHOT stage.)
Below table is my understanding for the document. Correct me if I'm wrong.
|11g||802.11b/g||According to ticket 17541, this value can also represent 802.11b/g/n(2.4GHz)|
|11a||802.11a only||According to ticket 17541, this value can also represent 802.11a/n(5GHz)|
|11ng||802.11b/g/n(2.4GHz)||According to ticket 17541, you should fall back to value
|11na||802.11a/n(5GHz)||According to ticket 17541, you should fall back to value
|???||802.11a/n/ac(5GHz)||What value shall we use???|
|???||802.11b/g/n/ax(2.4GHz)||What value shall we use???|
|???||802.11a/n/ac/ax(5GHz)||What value shall we use???|
BTW, are there any value for "802.11g only", "802.11n only", "802.11ac only", "802.11ax only"?
