Question: Can I set up wireless network using equipment from different manufacturers?
Yes! You can set up a working wireless network by using wireless equipment such as wireless router, access point or wireless adapter from different manufacturers without having any compatibility issue.
The wireless equipment are manufactured according to IEEE’s 802.11x standard, so they will work with each others. However there are manufacturers claim that the network works the best if you use all their equipment, this could be true to certain extent but might just be a marketing strategy.
Having said that, although wireless equipment from different vendors can work with each others, the wireless standard (802.11ax, 802.11ac, 802.11n, etc.) you can apply will depend on the wireless standards supported by each wireless component.
As an example, if your wireless router supports 802.11ax (WiFi 6) but the laptops, computers and other network devices are equipped with lower standard 802.11ac (Wifi 5) only, then you can only run wireless network with WiFi 5. Later once your network devices can support WiFi 6 you can then change the wireless router settings to run WiFi 6 network.
If you have a laptop equipped with WiFi 6 wireless adapter but also another laptop equipped with WiFi 5 wireless adapter, some wireless router does allow you to configure it to support multiple wireless standards at the same time (mixed mode).
Lastly, would like to point out that you can also run wireless network with 2.4 GHz and 5 GHz dual band concurrently to increase wireless network capacity and options by leveraging WiFi 6 standard.
Hope this helps..
