w7 RC: cannot connect to internet..no default gateway

[MathNole]

Hello all,

Well it started yesturday when I got home. I couldnt connect to the internet, tried restarting everything (pc, modem and router) and still nothing. It says "identifiying...no network access" the whole time on the bottom. Roommates all connect wirelessly perfectly (embarrassingly im supposed to be the computer person) and wired to the one that would be going to my pc.

I also have a asus mobo with "express gate" so when I boot up I can use the mobo and software on the HD to access the internet (which works, so I know that my hardware is fine) but when I boot into w7 it doesnt let me connect! These problems started last night!

This morning I need to check something for school, did a system restore to 2/4 and still didnt work.

I tried following http://www.sevenforums.com/tutorials/18203-internet-troubleshooting-guide.html and ipconfig/all, noticed I have a IPv4 (says preferred after the ip), subnet mask, dns servers, but no default gateway to continue the tutorial.

I then hard reset my router and still wouldnt work. Im out of ideas now. I dont have a dvd drive anymore so dont know if I can reinstall windows (dont have time now have a test tommorow!) so any help would be greatly appreciated!!!

Thanks in advanced!

Also note:
In internet options, the lan settings are set to auto connect.
Windows firewall is off
I uninstalled AVG thinking it had something to do with it

If it has been working and then all of a sudden bang!, could be some updates to the system. Have you tried doing a system restore to prior date?

Yes, I restored this morning to 2/4, (problems started 2/9) and nothing.

First thing to check is that you can browse to your router. Check to see that you can at least see it. Then check that your PC is on the same subnet as your room mates, and what your router says it should be on. Check to see that your router is not blocking your mac address.

Try bypassing the router and hook your network cable directly to your internet modem ( cable, DSL, etc). Make sure you have your network card settings to auto for IPV4.

Are you sure about the drivers for your network card? Does your motherboard have two Ethernet ports? Is one ( or both ) disabled?

That's about all I can think of off the top of my head.

Have you tried manually configuring the IP address, subnet, gateway, and DNS? If it's a desktop and will always be wired to the router, I recommend a static IP address anyway.

Is your adapter set yo auto detect Ip? check that it is, if it's set to manual IP, what are the default gate entry?

It could be someone has changed the router's local IP (192.168.1.1, it should be this as the gateway is the first IP of your network).

You can also check your mate's adapter setup, manual or auto detect IP.

Hello Jeff, thanks for the reply,

I cannot browze to the router (browser to 192.168.1.1) it shows same screen that cant connect. the rest of that paragraph i dont understand unfortunately.
(ALSO NOTE: ROOMMATES ONLY HAVE MACS)

I tried straight to router, didnt work. Even reset everything in every possible combination.

My mobo has one connection, it is currently enabled. I have disabled it and enabled it tons of times.

keep the suggestions coming please!

No I have not. But will try. Can you post the link to a tutorial (or i will find one and update this post to ask you if thats the correct method)? Thanks

Setting Up a Static IP Address in Windows 7
This explains setting IP, but can you set subnet, gateway and dns?

Have you turned your router on and off again rebooted it ?

Did you say you are wired to router? Have you looked at your cable to your pc from the router, Unconnect it from both and have a good look. Maybe been chewed on by a pet, just an idea, good luck to you with this problem, And welcome to SF

Go to Start > Control Panel. Click on Network and Sharing Center. Click Change Adapter Settings (on the left hand bar). Right click Local Area Connection and click Properties. Highlight Internet Protocol Version 4 (TCP/IPv4) and click Properties.

Click "Use the following IP address:" and fill in the fields based on your router's settings. You can look at roommates settings for this information. Use the same subnet mask and default gateway as them, just use a different IP. For example, if your roommates have the IPs 192.168.1.100 and .101, use .110 just to be safe.

For primary DNS, you should be able to use the same address as the default gateway.

That was the first thing I did. Over and over.

Yes wired, cable is fine I tested it on roomates laptop.

Creating a name and asking for help is a last resort for help. I AM NOT A NOVICE!

OK, Im going to give this a try, only need to figure out how to find that info on a mac.




EDIT:::

I read somewhere that if you set it to connect to other computers (like a buisness) then it wont work, you need to change to private. I

I see that in start, right click my computer, properties, change settings under "computer name, domain and workgroup settings" ....
I try changing "network ID" from "part of a buisness.." to "home computer" and forces a restart.

Every time I restart, is back to buisness, and says I need to restart it again if I want to chang it to home computer.

Is this the problem???

Launch System Preferences. Click Network. If it's connected wirelessly, click Airport. Then click Advanced. Click the TCP/IP tab. It should display all the information you need.

OMG THANK YOU SIR! IF I KNEW YOU I WOULD BUY YOU A BEER! (d)

Thanks a million. Time to go study some Material Science. I love you!
