First issue, thats 15$ adapter, Nano adapters arent made for long distance over 5 meters at all, no antenna.... Rather buy good old ALFA (Real ALFA, yes that one).
I can´t see any problem in my choice... and btw. in my country they don´t giveaway adapters, it did cost me $45 ! (Not happy about it, but thats life here.)
The router is 2.5 meters from my laptop and no walls between, so that is calculated into my choice of adapter too.
Rather USE 2.4G, than stupid 5G, 5G doesnt do well over wall. 2.4G is more reliable, and you cannot max out 80MB/s up and down. Thats internet speed of 400Mb/s up and down.
I can see about 25-30 people on the 2.4G and about 18 people on the 5G. When I use the 2.4G then am I kicked off the internet daily ! But on the 5G it happens less than 3 times a year ! So I can´t agree on that either.
I have 450Mb/s right now, but like to upgrade to 867Mb/s.
80MB/s ? What are you talking about ?
Antenna Diversity Type
This only applies if you have two antennas, you can select which antenna to use. However, you should probably leave this to the default which automatically switches between both antennas based on the signal strength.
Enable Adaptivity
HLDiffForAdaptivity
L2HForAdaptivity
"Adaptivity" seems to relate to ETSI's (European Technology Standards Institute's) adaptive frequency hopping requirements which are mostly for Bluetooth. I note that ALFA says your adapter contains some kind of anti-Bluetooth-interference device, which is probably what this is all about. It probably has a stripped-down Bluetooth radio that simply tells other Bluetooth radios to stop using the frequencies that its Wi-Fi radio is using.
The Adaptivity settings you're seeing don't seem to have any direct correlation to parts of the ETSI adaptivity test, so it's hard for me to say what it's all about. Maybe someone with deep knowledge of how Bluetooth AFH works might know what these settings mean. Then again, maybe these settings are very specific to Realtek's or ALFA's implementation, so perhaps no one outside of Realtek or ALFA would know what they mean, since there doesn't seem to be any public documentation about them.
THATS why I look for help here after google let me down...
ldpc Cap
LDPC is Low-Density Parity Check. It's a standard part of 802.11n and 802.11ac. It allows your 802.11 transmissions to be more efficient. You want it on for both VHT and HT.
QoS Support
For media streaming and etc.
STBC cap
STBC is Space-Time Block Coding. It's a standard part of 802.11n and 802.11ac. It allows your 802.11 transmissions to be more reliable and efficient. You want it on for both VHT and HT.
Wifi Config
Self explanatory.

Takes a bit of googling nothing all.
I DO know that, but google don´t always give you the right answer !
Shame that companies dont put that into manual, but we have to "
DIG" for it.
In the very very old days they did !
since there doesn't seem to be any public documentation about them.
