Supported wireless devices list

beelze · June 7, 2020 at 12:33 PM

I've started this thread because yet another time driver for my RT2870-based dongle has been broken (not the frist time, I believe somewhere in mainline kernel). I have another dongle, RTL8821-based, but it isn't suppoted. Thus, I need another wireless USB dongle, but I do not know what exactly I need? Is there any list of supported chips? Can I use for instance CONFIG_RTL_CARDS from mainline kernel for reference or what else? The vast majority of cheap dongles are unsupported RTL8811/8821… I found some amount of RTL8188CU devices, but I'm not sure that they are supported in LE, though I see there are relevant CONFIG_RTL8XXXU and CONFIG_RTL8192CU kernel options.

Upd: there is no /proc/config.gz and I was unable to find actual kernel .config to check for included drivers

Please note: some modules ffrom the list above may (or may not) also support some other devices. For instance, some RTL8812AU module builds I found support RTL8811AU as well. But some – aren't (at least that wasn't declared explicitly).

Though, we still need the official list of supported wireless devices. At least because it is a high risk to bought unsupported dongle.

There is no official list. There will be no official list. Why? .. because we're a small team and we have many better (and much more interesting) things to spend our limited personal time on than generating innacurate lists of wireless dongle chipsets from manufacturers that fail to upstream support for their products to the Linux kernel. As most HTPC devices these days include a wireless chip that is normally supported (and using Ethernet with an HTPC device is strongly recommended anyway) it's also a declining issue. You may have other views, but that's generally the team opinion.

Oh, thanks for your great work and excellent LE. Though, my intention was different – I'm wrote here not to force to do something or criticize anything, but just to ask for the help for «what dongle should I buy?». I'm using RT2870-based dongle for more than 10 years and one and only problem is that in some kernels (like current LE kernel, previous builds was unaffected) I periodically got the same «flush queue» error and I need to replug the dongle after that. Personally I see no benefits for using wired network instead of wireless – using dedicated 5GHz frequency. WoL perhaps? Someone may needed in this, of course…

Sorry but I do not understand what are «most HTPC devices», especially x86_64 arch… Using the list of those «most devices» I can found what wireless chipset are used there. In fact, I'm just looking for any guidelines for choosing the dongle. Thanks

Railink and Qualcom (Atheros) devices are normally a good option, as the drivers are almost always in-kernel which improves performance, stability and support. Sadly Realtek devices are cheap so everyone buys them, but they are a pain to maintain and have more bugs/issues.

beelze · June 13, 2020 at 8:20 PM

Spent 20 mins on aliexpress trying to find any Ralink or Atheros 5GHz USB dongle but no luck at all Literally, there is almost nothing to buy except Realtek

There are very few Atheros-based and Ralink RT2* and RT3*-based USB dongles, 2.4GHz only. Please also note – all CONFIG_RT2800USB supported devices (RT2770, RT2870 & RT3070, RT3071 & RT3072) are ancient today and RT2870 driver is buggy.

Also, I found small amount of Mediatek MT7610U and MT7612U-based dongles which are supported I believe. Perhaps it is sad, but support for Realtek devices is needed, in fact.

**chewitt** · June 14, 2020 at 10:19 AM Official Post

The MediaTek devices are in-kernel so even if we don't have support for them turned on (not sure, but I think we do) it's a trivial process to enable the driver in kernel defconfig and maybe pick some firmware files that are needed.

chewitt Can we do a device list, updated by users? Something like an initial post by an admin (like me ), and all users can post answers, which devices work for them. Then the admin will add the device to the list at the initial post (device name, chipset, LE version, hardware, user name), and deletes the users post after this.

PS: It's really hard (impossible?) to find a 5GHz device, which is not from Realtek. Many users have this problem.

assuming LE doesn't change the kernels (much), there is already a list (maybe not up to date ?):

en:users:drivers [Linux Wireless]

no ?

the intel's (PCI-E) in NUC, works too, at least my one (9560)

**chewitt** · June 15, 2020 at 12:58 PM Official Post

We've always resisted the idea of creating a list with LE, because the last decade of forum support with OE/LE proves users are rubbish at contributing to a wiki, and forum threads where people post "it worked for me" always end up being hijacked with "it didn't work for me" posts and over time (years in a forum) the thread ends up with stale information. Sometimes it's better to deliberately have no information than wrong information.

From time to time we also have moments of self-doubt about refusing to add more Realtek drivers, but then we do a kernel bump, they all break and we spend weeks hunting patches and new driver repo's, which holds up other activities, and then we're back where we started.

those are ancient devices mostly. not very (honestly, not at all) helpful when trying to buy a Wi-Fi dongle.

LibreELEC:~ # find /lib64/modules/5.1.16/kernel/drivers/net/wireless/ -name "*.ko"

ls -l /usr/lib/kernel-overlays/base/lib/firmware

Cheapo wifi doggles won't tell you chipset they are using. LibreElec supports devices recognized by Linux 5.1.6 kernel, if related kernel modules are compiled and firmware packages loaded.

sure ?

cklick: en:users:drivers:iwlwifi [Linux Wireless]

you're free to search on that webpage somewhat deeper.

AFAIK, it's the main page to see what's supported by the linux kernels and to provide a pointer for further investigation was my main intention.

I've never seen a USB dongle with an Intel chipset. Those are usually in pci cards

So do RTL8812AU dongles work out of the box?

rix81 · January 9, 2022 at 7:47 AM

just for information.

RTL8812BU - 5 ghz ac adapter - works in coreelec, but doesn't work in all builds (arm and x86) of libreelec.

Also wondering, what 5ghz adapter to buy for libreelec...
