So what you want to do it keep your LAN (local area network) as is, but be able to connect via WiFi and have those groups all work and talk to each other through Windows Home Group for file sharing etc. No internet access at all, correct?.
You keep saying in one connection configuration you can access the internet.
I can connect to the WiFi network, and it says I have Internet Access, but I can't connect to anything on the Web. If I unplug from the router, then I can access the Web.
But that you have nothing to plug the router into, no modem, phone line etc. So where are you getting your internet from?
What I take away from this is that you want WAN (Wide area Network, e.g. the Internet) or outbound to the real world while having your LAN (computers inside your private network) still work and talk to each other. Do you want those to have internet access as well... I assume not. If so, then by plugging in your router, and hooking up each computer to it all device set to DHCP they will connect to the internet. Then you can use password enabled file sharing to gab and push whatever you want.
If you want a LAN and internet access then follow below.
So first off you got your IP structure wrong. In a private network setup you cannot run 169.xxx.xxx.xxx IPs, these are not reserved for Private IP status. There are only 3 types that can be used for that they are
Meaning in a normal modem, router, computer setup. Your IP to the internet (this is the WAN side of your router) would be something like 220.127.116.11 (i made that up).
But your internal Private IP (the LAN side of your router) would be a private IP. Something like 192.168.1.212
Your router knows this and that could start your problem from the start. So lets fix this by following the below steps.
networking 101. (using static IPs to configure a LAN and WAN with share)
First off are you trying to use DHCP? If so we need to stop that on the computers BUT NOT on the Router.
Make sure that windows is managing your connections, and not a 3rd party application like RealTeck, or Dell wifi/lan etc.
Also check each device to make sure they all have the same system time, if not NO WORKGROUP will ever work. In a static IP windows has no internet to set the time against. Check years seconds etc.
Now lets configure your router.
go to your router's administration page and configure the built in DHCP server.
We will allow DHCP to do its job but limit the IPs allowed to be configured. Ill do 20 but you can choose whatever you want
192.168.1.0 Subnet of 255.255.255.0
Router IP is 192.168.0.1 (the routers IP)
192.168.0.2 to .22 (this gives us 20 DHCP reserve IPs to use, you can change this to what fits your needed)
192.168.0.100 to 122 (this is the static IPs for our computers or whatever we want)
Go into your network adapter for each device your connecting and you need to manually set the network up.
The issue your having is when your add the router its not a WiFi conflict its a gateway issue/ DHCP issue
so I will use the private IP of 192.168.0.100 to 122 range for this (being that 192.168.x.x cannot be assigned to public IPs.)
Computer 1 Computer 2
IP 192.168.0.100 IP 192.168.0.101
Subnet 255.255.255.0 Subnet 255.255.255.0
Gateway 192.168.1.1 Gateway 192.168.1.1
DNS 192.168.1.1 DNS 192.168.1.1
After you did all of this, see if you can talk to each-other.
on each device, (not the router)
go to start, run,
when the black screen starts type the following (this example is done from computer 1)
a list of network info will display, make sure your IP, DSN etc is correct. Then type
some text will run, you should see 4 packets sent 4 received.
same thing here, it should send and receive. 4 of 4. If not then something is not configured right.
it should return the same IP you typed.
Also make sure of the following issues that can mess this all up.
1. Make sure windows firewall is either disabled or that you allow the IPs through your firewall on both computers and all devices.
2. Disable antivirus when setting this up.
3. After all is set and saved you might have to turn off both computers, and the router. Plug back in the router, wait for it to boot up, then turn on your computers.
4. Make sure your share center is sharing with your other devices, and done in Admin mode.
If using a WiFi device this works the same, but you would configure the WiFi adapter on your Router the same way, and your device your using will need another IP for it.
So now to WAN, this is only for access to the internet. If your looking for connecting your wireless devices you need to use wLAN setting in your router. If your going out bound then (to the internet) with DHCP it will do it without your needing to configure.
But, if there is no internet your trying to get to then you need to go to the wireless or wLAN tab in your router,
and using the same private IP lists configure each WiFi adapter or device, using the same steps.
Let me know if this is what your talking about, because that is what I think you wanted.
Remember, LAN is you inside network, WAN is the internet, and wLAN is a wireless inside network, if you have a laptop with WiFi on it, you will need to configure both adapters. Ethernet(gigabit controller) and your WiFi adapter.
If your not using your router to get internet, then how are you getting it if at all.
