Networking trouble subnet related

so ive been trying to network my and my wifes computer for 2 days now with no luck. ive had windows 7 for a while now and she just had a fresh install. so both of us have windows 7 but cant see each other, I spent all day yesterday fighting with home group tutorials and everything until I finally realized that its a subnet issue,

the router is on 192.168.1.x as is my computer and the printer, so I can see both the router and printer in my network folder, wifes computer shows nothing.. her ip is on 192.168.2.x but when I try and manually put her to 192.168.1.x her internet stops and her "network" shows as offline. so I got this idea to change the router and my computer to 192.168.2.x so were all on the same network... so far so good. my computer and router changed over, internet still up and all working, but still cant see her computer, I ipconfig her computer and her ip changed to 192.168.3.x

just to recap

my computer
ip=192.168.1.2
default gateway =192.168.1.1

wifes computer
ap= 192.168.2.3
default gateway = 192.168.2.1


my computer wont work on her gateway and vica versa, I can only switch to xxx.xxx.2.x if I change the router to the same, but then her computer pops from xxx.xxx.2.x to xxx.xxx.3.x

basically its always 1 value higher then the router for some reason, and I cant figure out how to get her on the same octet so we can properly network..

any ideas? ill paypal 11 cents to whoever can help me! (wife suggested I offer a bribe)

xxx.xxx.xxx.xxx are octets, and should be referred to as such, otherwise people will think you are referring to a Subnet Mask...

Try this though, you said you tried to statically assign the IP addresses accordingly, but did you check if that was possible in Device Manager?

Some NICs will allow network addresses to be specified in Device Manager...

Let us know...

You have to keep all computers / devices on the same range (you can use NAT to get around this but its quite an advanced setup)

Your Router should have DHCP enabled by default meaning you should leave all the devices IP address's to Automatic.

Setting IP address's manually is just overcomplicating things. (unless you have a specific reason to have manual over automatic)

Im trying to get them on the same range, thats the problem.. theyre not...

i was trying to set them manually because they were on different octets/ranges (192.168.X) which are supposed to be the same so they can see each other.. for the most part I was leaving it automatic until I realized they were on seperate octets which is why I started trying to do it manually...

I once had a customer with an issue that sounded the same as this... In his situation he was connecting wirelessly and one of his PCs had different IPs as well... I asked if he may have been connecting to two completely different wireless networks... So let me ask you, are you connecting wirelessly???

What is your subnet mask?
Click start, type cmd, then type ipconfig /all on both computers and post all of the output here

Could you draw a diagram of the network?

subnet mask is the default, 255.255.255.0, tried changing the last 255 to 0 to 254 and a few other things ive read in my many hours on google but no luck, so its back to 255.255.255.0 now

no wireless involved, theres a router with internet coming in from the modem, 2 computers plugged in, and one printer. everything buy the wifes computer is in the 192.168.1.x range

if they're on two different gateways, you will have to find a way to connect your two networks first.

Looks like, from the last DHCP enabled posts, I would would bet your wife's computer has Internet Connection Sharing enabled and you are connected to the the sharing adapter or some kind of firewall software and/or a virus. Why would the wifes computer use 192.168.3.1 AND consider some fictitious system the DHCP server AND consider the router at 192.168.2.1 the DNS. Or you have another system in the environment with ICS enabled or router with DHCP enabled but when it senses a conflict, reconfigured itself so it is no longer in conflict.

Please dont leave anything out. Do you have any routers that are supposedly configured as switches, or any other wireless access point connected? Are there ANY other devices on the network. Does the router you use at 192.168.2.1 have any other special features like dual WAN, VLAN configurations, etc. Is your router capable of configuring guest networks for instance? Things like that.

router is netgear WNR3500L

only other thing that connects to it is my Iphone from time to time wirelessly and of course the wired in printer

router has a guest network feature on its page but i dunno what it is or how to use it so ive avoided it

router started out at 192.168.1.1 but I couldnt get the wifes computer to work on xxx.xxx.1.x so I figured id change everything else to match the wifes computer and changed the router to 192.168.2.1 but then wifes computer jumped to xxx.xxx.3.x .. args!

dunno what else I can add for more info, but if you think of anything you have but to ask

It does smell of ICS
Try disabling it on both your PC's,

Like mentioned, give that link a look and check your connections to make sure Internet Connection Sharing is disabled on both PC's. Have you done a spyware/malware check? Are they both fresh installs of Windows 7 in the last couple of days? Did you try disabling all firewalls temporarily to make sure nothing is blocking anything? Make sure only one network connection is connected to each PC, and though I dont think this might change anything, reduce the connections to JUST the two PC's just for troubleshooting (of course the router too - but disconnect the printer and the apple product).

In fact, if you have a basic switch with nothing else, just connect those two PC's to the switch and see how they behave, does the wife computer still get an IP? Or if you cant do that, disconnect the wife computer and see if it still gets an IP, that would tell you the wife computer is loopy and to isolate you to the one computer (assuming it has no wireless adapater or firewire cable connected (remember firewire is a network connection too)). No additional USB cables that arent needed for the time being, remember that USB transfer cables count (those used to transfer profiles when doing Windows upgrades too) as well.

wifes windows is 2 days old, mines about 2 weeks old... firewalls were disabled, pretty sure theyre still off, my phone is not on atm so good there, printer was allready off for most of the day, put it back on a hour ago to print something but will take it backs off.

ill take the modem off and see what happens, not sure what im looking for tho?

im assuming its the wifes computer with the problem tho, not mine even tho my installs older, since I can see the printer and router in my network page, and she cant see anything, im on the same range as the other devices and she isnt

But your computer can CAUSE it. If your wifes computer can get an IP WITHOUT being connected to anything, that means it is giving itself the IP and somehow running DHCP like a virus or unintentional setting.

I would also try disconnecting your modem. Are you sure your modem isnt also running DHCP, this can cause this?

Map it out for us, what is the IP of the router? If you type that into your browser on your PC, does it show you are connecting to your router and not the modem. What is the IP of the modem?

Can you log into the router and get a list of devices that have a DHCP reservation? Unfortunately I can't explain exactly how to do that because I have never used that router.

Normally by logging into the router and looking at it's WAN port details.

ok, under wan I see 192.168.2.0.. not much else in there

while I was in the router I did notice ip subnet mask is 255.255.0.0

should I change the pcs to that from 255.255.255.0?

Use Router as DHCP Server
Starting IP Address . . . 192.168.2.2
Ending IP Address192.168.2.254

that mean anything?


in ivp6 internet connection type is set to auto detect, but can be changed to DHCP

also further down the page IP Address Assignment is set to auto config, but can be changed to "Use DHCP server" instead

Hmm that may be a good idea but your wife may lose internet if you do that.

Could you post your DHCP server settings (Found on the router)

How do I assign an IP address to a specific computer or device?

1. Log into your router using the "How do I log into my router?" instructions earlier in this article.
2. To look up the IP address the computer is currently using, select Attached Devices in the Maintenance section of the router manager left-hand menu. Note the IP address (192.168.1.x) the device is currently using.
3. From the Advanced section of the router manager left-hand navigation menu, select LAN Setup.
4. Under Address Reservation, click the Add button.
5. Fill in the IP address (ex: 192.168.1.x), the MAC address of the device, and a name describing the device in the spaces provided. Click the Add button to save the information.


Could you post the info from step 2,

and go to step 4, don't click the Add button just post if you have any reservations

Don't add any reservations, just want to see if there are any existing reservations.


This SIPURASPA could be another router, looks like it's a VOIP phone or some sort

That would do it :) 

Plug your wife's computer into the router directly,

Then plug the voip phone directly into the router too, that should fix it.
