[SOLVED] How can I force my adapter to use 2.4 GHz?

[Jt00]

I get bad wifi reception in my dorm room, so to use wifi on devices like my ipod and phone, I set up my desktop computer as an access point and connect my devices to the hosted network. This setup used to work fine until I got a new internal wifi adapter for Christmas, which can use the 5 GHz band and automatically does so. Since my dorm's wifi has enterprise security, I can't just go out and buy a repeater, I have to run it through my computer. The problem with this is that my ipod is a 4th generation ipod touch, which can only use 2.4 GHz wifi, but since my adapter automatically connects to the 5 GHz network, the hosted network is also 5 GHz and I can't use my ipod with it anymore. I need to be able to switch channels when I want to have a hosted network, and I've come across a couple of programs that got very close to letting me do that, but none of them work. Annoyingly, the software that comes with the adapter allows you to choose a specific channel to connect to, but then just connects to the fastest network, i.e. a 5 GHz channel, with the same SSID (and every channel, both on 5 GHz and 2.4 GHz, has the same SSID). How can I force my computer to use a certain channel?
I'm on Windows 8.1 with a TP-Link TL-WDN4800 wifi adapter, if that helps.

I've found a solution, Wi-Fi Scanner by Systems Lizard (Lizard Systems?). The download on their website http://lizardsystems.com/downloads/ is for a trial version, but you can install the program, go to Help > Get registration code, and get a basic code for personal use for free. I'm able to select a specific channel and connect to it with this program, and now my ipod works again on my hosted network.
