   Usually, you can't *completely* saturate a WLAN channel with one client and   
   one TCP stream.  I just did a test with two laptops on my WLAN, running   
   iperf3 against a server on my LAN (so I am not limited by my internet   
   connection).   
      
   When I run iperf on both clients, the aggregated bandwith is actually a wee   
   bit HIGHER than what a single client can achieve - regardless of direction.   
   And with one client running iperf traffic as fast as it can, the other one   
   can use the net just fine, without perceivable delays or losses.  ping   
   latency on the unloaded client rises from 2-4ms to 20-40ms - this is not   
   really noticeable when browsing the web.   
      
   With both clients transferring data, they share roughly 50/50.   
      
   This is on an old 802.11ac (Wifi5) access point, with Intel AX200/AX210   
   modules in the clients, so modern features like OFDMA that might help in   
   this scenario are not available. And this is on a 2.4GHz channel in a   
   residential area where I am not alone on that channel.
