Crowd-sourcing the Wi-Fi Chip info

richb-hanover-priv · April 5, 2024, 2:02am

TL;DR: You can see the information collected to date here.

You can help collect information about the features of the Wi-Fi chips in modern routers. SSH into your router, run the commands below and post the results.

ubus call system board | grep 'model\|description'
iw list | grep 'Wiphy\|TXQS\|AIRTIME_FAIRNESS\|AQL'
iwinfo | grep 'Hardware:\|PHY name'

Why is this information important? How OpenWrt Vanquishes Bufferbloat describes the way the "OpenWrt Wi-Fi Driver" fights bufferbloat by using separate transmit queues/AQL/ATF if the chipset supports the right features. I asked the question:

How can a newcomer know whether a particular router has a chipset that is supported by the OpenWrt Wi-Fi Driver? Can they simply look at the "WLAN Hardware" entry of the Device Page and look in some table?

Here's a list of all the unique Wi-Fi6 and Wi-Fi5 chipsets currently used by OpenWrt devices (below).

To produce these lists, I took the zip archive of the entire ToH (from https://openwrt.org/toh/views/start) and separated out the WLAN Hardware columns. I made two selections from that list: Wi-Fi5 radios (that is, shown as "a/n/ac") and Wi-Fi6 radios ("a/n/ac/ax"). I then processed those lists to remove duplicates and came up with these two sets of radio chipsets.

I think you can refer to my post here to suggest people creating a line like the following then you just need to append to your list without too much editing

I'm not sure this is helpful. How can a newcomer tell which of the chips in Wi-Fi6 and Wi-Fi5 lists (in the original post) are considered "mt76" chips? Thanks

richb-hanover-priv · April 10, 2024, 12:45pm

@tapper @fakemanhk @Pouakai - thanks for the info. I have entered it into the table.

greem · April 10, 2024, 1:10pm

The ones with MT76xx designations all use the mt76 driver - see https://github.com/openwrt/mt76

fakemanhk · April 10, 2024, 2:56pm

Question: I followed your command but it doesn't show me the WiFi hardware MT7976CN, am I missing something??

brada4 · April 10, 2024, 7:48pm

All Mediatek MT76xx MT79xx chips have full driver support. Probably worth digging other driver sources for similar blanket conclusions.

richb-hanover-priv · April 10, 2024, 9:02pm

@brada4 @greem Thanks for the confirmation re: MT76xx and MT79xx. I have updated the table with the information that those chips support all the features of the OpenWrt Wi-Fi Driver.

@fakemanhk You are right. I (mistakenly) believed the ToH entry for the GL-MT3000 instead of the actual evidence you send in. The table above now shows that all MT79xx chips support all three Wi-Fi features. I have corrected the WLAN Hardware entry on the MT3000 Data Entry page.

richb-hanover-priv · April 10, 2024, 9:26pm

@slh @tohojo I'm making pretty broad generalizations about the MediaTek ecosystem above (all MT76xx and MT79xx chips support the three Wi-Fi driver features). Is this true?

Also - any broad groupings of Atheros chips? Or will the table have to be updated chip-by-chip? Thanks.

brada4 · April 10, 2024, 11:53pm

Source code... TXQS is WMM queues omnipresent since wifi4 plus kernel mac80211 moderation of their size.

tohojo · April 11, 2024, 4:08pm

I think so, but not entirely sure...
