Of the two suppliers that do provide USB Wifi chipsets, Mediatek supports drivers for their chipsets the right way, in-kernel. Mediatek drivers are Linux Wireless standards compliant and are updated constantly without users having to worry about it. Realtek does not support their modern USB Wifi chipsets with in-kernel drivers. Realtek does make non-standards compliant Linux drivers but does not publically release them or take problem reports.
These drivers are released in source code format and must be compiled to be used. The Realtek drivers do not keep up with the needed changes as new kernels are released. This job seems to rest with folks like myself in the community.
What do I recommend? Buy adapters based on chipsets from the company that is doing it right - Mediatek. The biggest problem most Linux users have when looking to purchase a USB WiFi adapter is being able to reliably identify which adapters have in-kernel support and that is really the reason for this site.
Spreading this information far and wide is key to having happy Linux users so please do spread this information. This document attempts to identify currently available adapters that use in-kernel driver support. Links are provided to online products. Information regarding out-of-kernel drivers and their quality is also provided. The hope is that this information is of benefit to Linux users, experienced and new. Links to products from a wide variety of retailers are provided and we welcome you to send additional links that can be included.
The chipsets are shown in each category and if you are able to find an adapter with the listed chipset, even if it is not an adapter that is specifically listed, it should work. Linux Wireless - Mediatek is a good place to get an idea of the various Mediatek wifi chipsets that are supported in the Linux kernel. If you want to look in the kernel to see the drivers, look here. One of the biggest advantages of using adapters with in-kernel drivers is that any of us can report bugs and submit fixes.
There is no way that I am aware of to report bugs to Realtek. Warning: It is common for online retailers to post "Linux support. Most inexperienced users do not understand that the Linux kernel is under constant development which makes it necessary for drivers to be regularly updated in order to work on newer kernels. Out-of-kernel drivers sitting on a CD or on an adapter seller's web site do not get regular updates.
Rule of thumb: Never attempt to install a Linux driver from a CD. Only consider downloading a Linux driver from an adapter seller's website if you confirm it supports the kernel you are using first. The out-of-kernel drivers on that CD or seller's webisite will likely be old and will likely do nothing more than make a mess of your system. Remember that sudo is a weapon of mass destruction if used without knowing what you are doing. All major Linux distributions have active forums with users ready to give advice.
Don't take advice from a single user but seek advice from several users and always ask if the adapter uses in-kernel drivers.
The problem is that the state of the adapter has to be changed for the adapter to show up as the device that you expect, in this case, a WiFi adapter. Most modern Linux distributions ship with a utility called "usb-modeswitch" that will handle this issue for you if it has the correct information for your adapter.
It is a good utility but if you buy adapters that are "multi-state," that is one more potential headache you may have to deal with when something goes wrong. Often you can indentify adapters that are "multi-state" as they are advertised as "free driver" or "free installation driver. Both companies regularly change chipsets while keeping the same model number on their products.
This makes it very difficult for Linux users to buy a product with a specific chipset with any degree of certainty. This also makes it difficult for me to post links and recommendations so I will not do so but that is okay because there are many good adapters available. TP-Link and D-Link's Linux support is very poor as their product support sites generally only contain very old Linux drivers that won't work with modern distros We know that Linux cannot be properly supported in the manner that both companies use.
This is sad because both companies have made a lot of money from Linux by using it inside many of their products, yet they do not return the support. Note: Adapters made by two companies need to be highlighted. The quality and reliability of most Panda and almost all Alfa adapters is good Not all Alfa adapters use in-kernel drivers. The Alfa adapters that do use in-kernel drivers are listed below.
Products by both companies are widely available. I have tested adapters ranging from N to AC Based on upstream work and work on core distros, I expect that we will see WPA3 working well on the newest releases of almost all popular Linux distros by mid Many distros already work well.
USB extention cables with cradles can be very useful with USB WiFi adapters as they will allow you to position the adapter for best performance.
