sounds like you're not your IT group. you need to get with them about the setup. as something seems to be done fairly specifically there. you've been given a static IP, and DHCP doesn't seem to be available on the network (hence the automatic IP).
the RTL8723AE is your network card in the laptop, not the router. someone with direct configuration access to the router would need to make the channel changes on the router.
dsenette, sorry, I just misunderstood the first question I thought you were talking about the configuration of my laptop. lol.
I was the one who configured the wireless network card in my laptop to work as router and share interned with others. I used the netsh wlan set hostednetwork commands, as well as My WIFI router software. I mean, it is not possible that my provider actually possess the router I use or something like this since the WIFI hotspot I created works only in my flat. In addition, it actually works and people can use my interned. The only thing is that their devices disconnect and reconnect often and that is the problem. So, I found on the web that I should change the channel of my router to 1, 6 or 11(not it is 10) that are the least interfering with each other. However, I just cannot access my router or virtual router, I am, honestly speaking, not good at it.
Can I use a software to change the channel? Can Connectify or smth do it?
