Okay, first off I'll understand it if I don't get official support in this, because it's not the average question a normal user would make. In fact, it's hard even to explain.
Back in the day I bought a D-link 300 to share my internet connection with my family, since my old modem had no wi-fi. Later in time, my internet provider changed our modems and the new ones included wi-fi routers, so I stopped using it.
But now I've come in the need of something that is not easy to achieve.
In short: I need to have my PC connected to my modem via Ethernet, AND I need my pc to have a wi-fi device connected to it to broadcast a virtual network. It's crucial that my pc is in the middle of the internet modem and the virtual wi-fi network.
So, since my PC has two ethernet cards, I connected my modem to one and the d-link dir 300 to the other. Which kinda works on paper - except I need my computer to actually be the one broadcasting the network, or at least thinking it's doing so.
The reason over it is that I'm using a program called instacheck to capture certain data from my mobile device - which I need to later analyze, and for that, the program needs to create the network using Virtual Router Plus. But sadly, instead of that, what I'm getting is that the program identifies the network as an ethernet one - and the Dir-300 is working smoothly, I'm connecting to Internet through it.
So, if I'm even able to word that question: is there a way to make the ethernet card transparent and make it "look like" the access point connected to the ethernet card is actually a wireless network card? Which would mean I'd need my pc to be able to configure it without using the d-link control panel...
P.s: This is less important, but for some reason, I can't even access control panel from my PC. My main router uses the 192.168.1.X range and the Dir-300 uses the 192.168.0.1 range so there should be no conflict. Also, the DHCP isn't working, I have to manually input my network IP address to be able to use the DIR-300.
Edit: I figured out a part of my problem. Since my pc was connected through the "internet" ethernet entrance of the access point, it wouldn't become a part of the LAN. I changed it to the entry "1".
The problem now is that you can't connect to internet throught the DIR-300, obviously. I don't know how I'll subsanate that.
