Take the Dell XPS 9520 as an example - it has an AX211 Killer 1675 adapter, but the laptop will not use the 6 GHz frequency range at all. At this point, there are only assumptions, but a popular reason for this behavior was that Dell did not update the antennas, so they could not work correctly with the WiFi 6E network card.
new wifi network card
Yes, WiFi 6E is backwards compatible, so the regular 2.4GHz and 5GHz antennas should still be supported, but since there are no changes to the antenna design to accommodate the new frequency range, you may actually see worse WiFi performance than simply sticking with WiFi 6.
So, keep that in mind before you buy a WiFi 6E card and replace the WiFi 6 card in your laptop, because if your laptop doesn't support WiFi 6E, you may not see any real performance improvement.
Yes, we're still talking about moving to WiFi 6E, even kuwait telegram data if it's not in the process of being widely adopted and won't be for years. But Intel was lazy and Microsoft was kind of an asshole, so here we are.
You need Windows 11, which in my humble opinion is not worth it, otherwise you will not be able to use WiFi 6E cards. That's just great, right? Well, if you needed another reason to switch to Linux, this is it, because if your laptop or desktop cannot be upgraded to Windows 11, that new network card is useless. Another software-related aspect you need to consider is the authentication method, as WiFi 6E requires either WPA3 or OWE and nothing else. For now, as these things tend to change very often in the networking world.
