Laptop and now reduced speed while using the 2.4Ghz WiFi band... (nothing major)

If it's intended to work this way, I'm not sure it's an issue to fix.
If you're looking for the maximum speed possible, open the wifi settings and go to Advanced->WIRELESS.
1. See if you can use 5GHz, set the Wireless Mode to 11a/n/ac and set the Bandwidth to 20/40/80MHz.2. If you have to use 2.4GHz, set the Wireless Mode to 11n-only and the Bandwidth to 20/40MHz. I don't recommend the 11b/g/n setting because I know the "b" part confuses some boxes like the XBox 360.
Has to do with the available bandwidth on the wifi network wrt protocol.
For example:
Unless the 2.4GHz wifi is set for n-only, you will have only a 20MHz wide network with only one channel.
n-only on the 2.4 GHz network spreads it across 2 wifi channels for a 40MHz network.
Compare that to the 5GHz network that potentially spreads it across 4 wifi channels for 80MHz in ac mode.
