The same page for PCIe ones lists a lot of Intel and BCM ones (I wouln't buy BCM of course but I know there is some BCM stuff in Debian). All my WiFi adapters I ever used with Linux (included with a laptop, included with a motherboard, bought separatele for PCIe) were either Intel or Ralink and all of them worked fine without extra drivers, even though iwlwifi sometimes breaks with some kernel versions. -- WBR, wRAR signature.asc Description: PGP signature

Recently I had to choose and buy a USB WiFi adapter suitable for making a software access point. And this is in a semi-rural area, so almost no interference from neighbors.

I ordered a (Mediatek-based) Alfa Networks AWUS036ACM adapter from Amazon, but it took way too long to arrive (it did, eventually, long after I have given up, that's why the local shopping attempt). So I ended up buying a TP-Link Archer T3U v3.2 in a local shop and using it with a driver from https://github.com/cilynx/rtl88x2bu, and it does yield throughput higher than the theoretical limit of USB 2.0. -- Alexander E.

It would be easier for you to list ones that you've actually tested and know work. OK, whatever. It's a serious request. In 20 years of trying different wireless devices I've had just one that's completely reliable under linux (atheros qca6174 chipset) even if it's a little slow (only 2x2 mimo, and possibly hampered by the laptop's antenna configuration). It's older 802.11ac; I haven't ever seen a working 802.11ax. (Not saying it doesn't exist, just that I haven't seen it--hence the question!) I've seen lots of reports of reliable devices, but they tend to be things that are either ancient, or hard to find, or simply don't work as well for me as for others (apparently). I've personally used a lot of devices that mostly worked, until they hung or started going really slow or in some other way behaved much worse than the phone sitting next to the laptop (ironically running linux). I've heard good things about the intel adapters, but AFAIK they aren't available in USB so if someone didn't happen to get a laptop with that solution integrated it's not a simple end-user addition. IMO, wifi is the last major pain point to a fully functional linux sytem. Most other things these days you can just buy a something off the shelf at the local electronics store and odds are all the pieces will work out of the box. But wifi still requires a good bit of research, and isn't something a novice will find simple unless they get lucky on their components or bought something from a specialty retailer that focuses on linux systems.

I do not think so, I guess this mostly depends on how many people are involved with each driver and how well tested is the code. In the particular case of rtw88 driver (the one supporting chipsets in the subject), it is maintained by Realtek folks with additional contributions from the community. Some chipsets are supported, some not yet. For the case I know (rtl8821ce), original chipset is supported, but support for other variants (e.g., rfe 2) was late for 5.11 (Realtek tests took longer than expected), but will be present in 5.12 kernel, requiring new firmware (https://lkml.org/lkml/2021/2/2/76). I think the best option is to wait for that kernel and firmware to reach debian-backports. For other variants of other chipsets things may be fifferent. Regards, -- Agustin
Re: Realtek RTL8723DE, RTL8821CE, RTL8822BE and RTL8822CE chipsets
This is interesting. First, I must ask... Are either Ralink or Atheros more quickly adopted into Linux support before Realtek? Are they more stable, etc.? (In my original post, I noted that I pulled a Realtek based 5ghz dongle from an extreme end user system, in no small part due to stability/reliability)? Second, I must note that perhaps you *were* lucky or whatever, as I have never found anything other than a Realtek chipset on offer. Even if Atheros or Ralink are more stable, I don't know if I could actually *find* one. I am well aware that the Chinese company's dongle made in People's Dongle Factory Thirteen will have folded before the container ship hits the States, but the Realtek chipset is the key...it is finally why I know that can work with it.

Re: Realtek RTL8723DE, RTL8821CE, RTL8822BE and RTL8822CE chipsets
Something I did not mention before, to answer your question the chip reads as rtl8821cu (so yes, a Realtek). In fairness I do not recall ever having run across a wifi dongle that did not have a Realtek chip (although they may be out there). It was because I could at least confirm a Realtek chip in an otherwise cheap Chinese dongle, that I was willing to even try it.

Re: Realtek RTL8723DE, RTL8821CE, RTL8822BE and RTL8822CE chipsets
I will note something similar, except that I went into it with my eyes open... Originally (10 years ago), 2.4ghz wifi was not natively supported. Okay, said we geeks, can it be compiled and inserted manually? Yes, it could. I wrote a script to compile and insert said driver, and thereafter, every time there was a kernel update or patch, that's what I did. And it worked fine for the couple of years it took for 2.4ghz to be natively supported in Linux. Fast forward to 2 months ago. Looking at 5ghz wifi, I *knew* what I was volunteering for when I saw a 5ghz wifi dongle on Amazon (one of the questions was: Is it supported for Linux? *I* snickered, as I has a very good idea what the implications were). I bought one, and, back to old school, I can and do run it, manually compiling and inserting the driver as needed. It's a very familiar process. Here's a real world application: in fact I bought *two* 5ghz dongles, one for myself, one for an *extreme* end user whose system I administer. On my system, as needed, compile and reinsert driver. On her system, I pulled the 5ghz, went back to the 2.4ghz dongle, trusting that she won't see the difference. No big deal, not a complaint, I am PERFECTLY comfortable with compiling and inserting a driver (compare and contrast that to Windows, where you are SOL if there is not a driver available, I *do* get it)...more a point in the right direction. This is where we were 10 years ago with 2.4ghz. On 3/29/21 8:59 PM, Timothy M Butterworth wrote: > All, > > Currently in Bullseye the Realtek 8822CE WiFi adapter is not being > recognized.
