I realized my ASUS PCE-a68 AC1900 is $129(currently on amazon), it was given to me with an older custom built tower. I also looked up on when it was released and i saw it was back in 2013? I might be wrong i don’t know. I was wondering why it is that much for that specific wireless adapter? The last driver update for the AC68 (AC1900) was for Windows 10 in 2016/2017. I was looking up more recent ones like the TP-Link AX3000 and its only $44.99 for black friday. I used pcpartpicker to see what wireless adapter can work with my desktop and the TP-Link BE9300 says its not compatible. I thought any wireless adapter would work?? My current desktop is this link here My Build i can’t do ethernet. Why is the asus one that much if its older?? And newer ones are cheap??
