Slow link speed on my 2.4 band for my Laptop during negotiation?

So, I ordered my Nighthawk lastnight, and somehow got it delivered this morning by 10 AM (yes on a Sunday), deliver within around 12 hours of buying it. Wow, great huh, I was shocked and like a kid ...

What's the model of the Wi-Fi adapter on your laptop? I'm guessing that it is single stream 802.1n. Such an adapter can only get a link speed of 150 Mbps when using a 40 MHz wide channel. Were you forcing your old router to use 40 MHz? You can try disabling 20/40 MHz coexistence in advanced wireless settings on the Nighthawk. There's no guarantee that those will work. Note: Using 40 MHz channels isn't very neighbor friendly because it consumes 2/3 of available spectrum at 2.4 GHz.

Oh, and I did switch to your suggestion to verify if the 20/40 coexistance was causing the slower negotiation, and it jumped up right away, I had thought that this may be it before posting originally, and considered checking it out, but really was not wanting to be a network jerk, if it was unecssary, and I am not really having speed issues, just wanted to see what I could do if anything about this.

Additionally, would updating my NIC's driver make any difference on the connection speed with the Model number I provided? Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC

I am thinking that this will not matter as it is limited by hardware age, but if you know anything that I may be missing?
