Hello,

I'm planning to set up a router that will create an offline wifi network to which a couple of wifi devices will connect. Note that I'd like to keep this network offline because I live in a dorm and the network is iffy at times and requires weird authentication and, also, because I'd like some more security for the devices on that network. Then, I'd like to be able to connect the router to my computer via an ethernet cable and still be able to use internet from my dorm's wifi network.

Is this setup possible and if yes, please advice me how to configure it. Alternatively, if you can think of a different approach I'd be happy to reconsider.

Let's once again see what you want:
- a WiFi router / access point, connected over Ethernet to your PC.
- Your PC is connected over WiFi ti public Internet
- From your PC, you want to access both Internet (thru WiFi), and devices connected to your private WiFi

If that's the case:
- Assign Ethernet port with static IP address outside of Dorm' WiFi address space (that is, if you get 10.20.30.40 over WiFI, set 192.168.10.1 on Ethernet)
- Configure your private Router/ LAN port with static IP address from same network, like 102.178.10.2
- Enable DHCP on private router with 192.168.10.x scope
- Done

First a question, what OS are you using?

If the computer with wireless access to the dorm network will be left on all the time that you want your distinct wireless subnet, I would use Connectify Hotspot as sharing the Internet signal with a separate router would require a network bridge in the connecting computer that would create a security issue.

I travel on business a lot and use Connectify, which is just awesome -- very simple to set up with your own SSID and security passkey. It is only as good as your initial network connection though.

And you obtain the Internet access from the wireless adapter with?

ICS? Nope, won't work with a router.

Bridging the adapters? Nope, opens a giant security hole.

What am I missing here? (Had you assumed that he had Windows 7 and could create a virtual miniport and create an access point that would make sense to me)

If he wants Internet access to his wireless subnet ICS will not work with a router -- it requires that it do its own routing, and as I noted bridging networks approach is secure in this situation.

And if he doesn't want access for his private subnet why would he need to connect it to the computer that has Internet access, that would be silly. His devices, such a phones/pads would not make any sense just connecting to one another.

Yup, I made an assumption on what he is trying to do based on the hundreds of others that are trying to do the same thing because it is what makes sense.

You guys are brilliant! I certainly didn't expect that many answers when I got up this morning. Great community!

I apologize for not stating my OS, it's quite obvious but slipped my mind - Windows 10 Education N 64bit.

@Abalacho has struck the nail on the head. That's exactly what I want to do and he has spelled it out quite clearly. I'm not outstanding with computers but I believe what I don't know is a google search away.

@RealBeast I don't need internet on the wifi router network, just on my computer bu thanks for entertaining the idea anyway, I learned something new!

Thank you both for chiming in. If I have any questions I will post further in this thread. In the meantime I'm marking @Abalacho's answer for Solution.

Hey guys, I went ahead and tried to do what you all suggested but to no avail. As I'm not that good with networking I tried to google my way through but I couldn't make it work.

First I ran ipconfig /all in the command prompt with the router connected via ethernet cable. This is what I got in return:

Ethernet adapter Ethernet:

Connection-specific DNS Suffix . :

DNS Servers . . . . . . . . . . . : 192.168.1.1
NetBIOS over Tcpip. . . . . . . . : Enabled

I put the values I got from the command prompt into IPv4 Protocol settings with ip 192.168.0.110. I chose this ip address because my router (pic3) seems to support this pool. I left the router in DHCP (pic1).

Pic 3 - https://drive.google.com/file/d/12AfVzyHZQs889Pcgf4sR5c...

After I put in the new ip the router needed to reboot but after that when i tried to type the new ip address in a browser the router ui wouldn't load. After that I did a factory reset to the router and now I'm pretty much on the starting line.
