Everything goes through the router, but this doesn't halve the available bandwidth.
That's a capable router. You should focus a bit of attention on optimizing your wireless network. There are many references on the internet, do a search and some reading, it's not difficult and could be a fun experience for you. In a nutshell, first look at placement. Then use a wireless scanner to determine the channels available. There are many tools for this, or you can use the Cisco Meraki website (Google it). The goal is to select an available channel with the most separation between other channels - the one off by itself is the one you want. This will eliminate as much as possible interference from other equipment. If you're in an apartment building the channel graph is likely to be lively. Once you've done this configure the netgear with the desired channel (the default is auto). Also give your router a different SSID than the default, make it unique. Most other settings should be optimal already, just in case make sure 20/40MHZ channel width is set (40 is optimal, 20 is for legacy equipment). You may need to experiment with different channels, this requires a bit of patience, but most often the one by itself will work best. Moving the router may be necessary to gain more separation, especially in apartment buildings. Last, which I don't recommend, you can boost output power. This often requires hacking and/or a different firmware. Another change you can experiment with is turning off SSID broadcast and make sure everything can still connect. Again if living in a rural area, if SSID is broadcast neighbors devices can see this, and even if WEP or WPA are used (and you should use them) other equipment may try to connect, which can seriously affect performance.
You have capable equipment and should be able to do what you want. However there are multiple factors at play, and sometimes the only recourse is to revert to wired. I stream high bandwidth content with ease, but then my nearest neighbor is a third of a mile away and my network is optimized.
Geek out and have fun
