Thank you!

Hi @vinhnv211

There is more than one RTL8812 chipset- 8812au and 8812bu for usb and more of the same for pcie and sdio so you need to be specific.

I am certainly not in the know on everything out there but when I last checked, IoT devices were mostly using low power WiFi 4 (n) chipsets. I'm not sure that the rtl8812 series of chipsets would be a good choice for IoT as the electrical usage would likely be a problem.

Generally speaking, if I were building/designing an IoT device with Linux as the OS, I would run screaming into the night before using a Realtek chipset that is only supported with out-of-kernel drives... there is a security issue... and a maintenance issue just to mention a couple of problems. A rt5370 or rt5572/rt5372 (if you need dual band) would probably work better.

Overall, I can't really answer your question because you are not providing enough information.

Thank for your answer. Actually I have single band 2.4G router that already is available in market.
Now customer would like improve it to support WiFi 5G. because of price so we choose RTL8812 (Wodesys WD-4607AC) and need integrate it into our router software.

Could you give more info about security issue for this driver ?

Best regards,
Vinh

Good day Vinh,

because of price so we choose RTL8812 (Wodesys WD-4607AC)

It is fairly common for me to be contacted by individuals and small companies looking to integrate wifi into their products. I will work in a consulting roll if the job is one where my experience can be of benefit.

With that said, I have seen comments like the above many times. I cringe when I see it because there is far more to cost than an initial purchase price. What is it going to cost when you need support and their is none... I have tried to contact Realtek and have never had a reply. They are of no help with this driver. I try to keep this driver going to help the user community but I try to point folks to the adapters that use in-kernel drivers because those adapters and chipsets are SUPPORTED and security issues are handled in a timely manner. I don't have time to deal with security issues in this or the other Realtek drivers that I maintain. I recommend strongly that commercial use of usb wifi adapters that use Realtek chipsets be AVOIDED because you have no path to support unless you are a multi-million dollar company. On the other hand, the chipsets and adapters that are supported in-kernel... you can reach out directly to those that work on the drivers to report problems. Seriously!

Could you give more info about security issue for this driver ?

There is NO security work on this this driver. I barely have the time to keep the driver going, let along work security issues. Something else to understand is that this driver is not Linux Wireless Standards compliant. That makes it hard to maintain as it doesn't work the way it should and documentation is basically non-existent.

The Main Menu for this site is located:

https://github.com/morrownr/USB-WiFi

It includes options for adapters with in-kernel drivers and various chipsets. It is a good idea to start with menu item 1.

I hope this helps,

Nick
