Wifi adapter that actually works out of the box

Mon Jan 09, 2017 5:42 pm

So I ordered a TP-Link TL-WN823N because according to http://elinux.org/RPi_USB_Wi-Fi_Adapters it "Works out of box on Raspian". Now that I've actually got it, it turns out that's not the case. It shows up in lsusb as just the device id with no name and not in ifconfig. Apparently that's because there's not actually a driver included in raspbian for this. I found viewtopic.php?t=148389&p=1028428 which talks about all of this, but a solution that requires compiling driver code from some random guy's dropbox is, frankly, absolutely nuts.

Does anyone have any recommendations for small usb wifi adapters that *actually* work out of the box with no compiling of drivers needed?

There are two versions of the TL-WN823N wifi module. TL-WN823N V1 uses the 8192cu driver included in the Rasbian image. TL-WN823N V2 uses the 8192eu driver that is not included in the Rasbian image.

I expect yours must be the TL-WN823N V2.

I expect so - is there any reason why the newer driver isn't included in the image?

I've had good luck with the Realtek ones (RTL in the chip number) and surprisingly a Ralink that wouldn't work under OpenBSD. You don't so much care what brand is on the outside as what chip(set) is inside, that's what has to match the available drivers. And a $50 one isn't necessarily better than a $5 one, unless you get into obvious features like a gain antenna. Most are made in China, and somewhat engineered there. Don't be afraid of getting on eBay and picking up something really cheap direct-mailed from China. I've had close to a dozen of them over the years. Most are too old to do 80211-N mode, some won't do host mode. Don't spend much, like over $5.

I have had the opposite results with the RTL chips. The USB dongles overheat, they fail often, and even when working they disconnect often. Reload of the drivers does not consistently solve the issues, full reboot often required.

What I am looking for is a wifi dongle for RPi that works, consistently, over long periods of time, weeks and months not hours or days, and does NOT overheat. Anyone have any suggestions?

Your link doesn't work. Try:

https://www.raspberrypi.org/products/ra ... fi-dongle/


Which is supposed to direct you to http://uk.rs-online.com/web/generalDisp ... aspberrypi but doesn't....

And which doesn't have the Wifi stick on it....

You'd think they would have left a redirector in with this new facelift, I guess not.
That was the link on the day I posted.

I have a bunch of cheapo WiFi dongles that I purchased from Amazon for about $1.50 each.

It works out of the box (or pouch as the case may be). Its only 150Mbps but it is sufficient for my requirements.

Used it for RPiZ, RPiA+, RPi1B (c) 2011, RPi1B+, RPi2B, and other SBCs without built in WiFi.
Samba transfer speeds did not suffer. No problem encountered on video playback on RPi1B-Kodi setup

No additional drivers were installed to make it work.

I've used branded 300Mbps and 450Mbps WiFi dongles, they tend to overheat (at one point I added a heatsink on top of the USB port).
After changing to the cheapo ones, I removed the heatsink.
