Hey

 

I posted this thread in the Windows 7 forum and a user there recommend I move it to the networking forum. Here is that topic:

 

http://www.bleepingcomputer.com/forums/t/593594/one-laptop-cannot-connect-to-wifi-network-other-devices-can/

 

Basically I got a new router/DSL connection yesterday. It set up smoothly and several devices have no problem connecting to it and getting online. However my primary laptop will not. 

 

Important note: the laptop in question CAN connect to all other WIFI networks (both private and public). It will connect to the new network but there is no internet access ("identifying"/"no network access" etc...)

 

I tried turning on/off router. Tried uninstalling and reinstalling the network adapter drivers (Ralink 802.11n). \

 

You can read several replies and other things I tried in the other thread. I also posted ipconfig logs from both the laptop which is not working and an older XP laptop which is successfully connected.

 

Also: I can successfully connect through Ethernet cable directly to the router

 

Any help would be appreciated. Thanks

 

Oh yeah I made a Speccy snapshot: http://speccy.piriform.com/results/7j5Fe4sRrVEmReLEIlCukK0

 

I will also re-post the ipconfig logs...

Anyone? I still haven't resolved this unfortunately.

 

If you notice in the logs the ip addresses from the working laptop and the non-working laptop are different. I just don't know what to do with that information. Any tips appreciated.

Your Windows 7 computer is configured to connect to a different network, and subnet than the XP computer, and it doesn't have a default gateway configured, which is your router.

 

Try this:

 

Start > Control Panel > Network and Sharing Center > Change Adapter Settings > Right click on your wireless adapter (post a screenshot if you can't figure out which one it is, will either say wireless or WLAN) > Properties > Scroll down to Internet Protocol Version 4 TCP/IP and double click it. It will bring up a configuration window. Select "Use the following IP address" and type in 192.168.1.50 for the IP address, Subnet mask 255.255.255.0, Default Gateway 192.168.1.1 > Now click OK to close both config windows

 

Now reboot and see if it connects.

Thanks for the reply.

 

When I try those settings I cannot connect to any networks. When I revert back to "obtain automatically" I can connect to all networks except the new one. 

 

Should I be inputting something in "use the following DNS server"?

 

Also, is it possible I should be using the IPV6 settings instead of IPV4?

 

edit: also should note I can connect to the router in question using an ethernet cable and there is internet access. Just not wirelessly.

Seeing as the Wireless does work on other access points , i would reset your Modem/ Router back to default ,  not just on and off.

Then do the Quick Setup for your provider info and try again.

 

Prior though you could check the Mac Addresses within the Router for the "Wireless Allow or Disallow" of any { To Your  Primary Laptop - Wireless Card Mac Address }. .....Although if you do the Router Reset to default it will clear them anyway.

Well normally your router provides DHCP (Dynamic Host Configuration Protocol) which automatically assigns clients (laptop or cellphone or computer or printer) internal IP addresses and configures their TCP settings. It also automatically handles the DNS (Domain Name System), which resolves domain names to IP addresses, such as bleepingcomputer.com = 190.93.243.116. So when you connect to your router, it should autmatically assign you an IP address, configure your subnet mask (which specifies which sub network you're on), and handles all the DNS according to whichever DNS server it's configured to use, which is usually the ISP's DNS server by default. I just don't know why it's not automatically doing this process for you.

 

As Havachat alluded to, maybe it's preventing your computer from connecting through MAC address filtering. MAC addresses are hardcoded unique identiers, almost like serial numbers, for network interfaces. Routers can block access to the network based on these MAC addresses, so if this is the case then it should explain why you can't connect. If it's not the case, then I have no idea what's going on. By configuring your WLAN adapter to use 192.168.1.50 IP address, subnet mask 255.255.255.0, and default gateway 192.168.1.1, it should connect you to the network your other computer is on, but it's not for some reason.

 

Using IPv4 shouldn't be any problem.

 

I would agree with Havachat that you should reset your router and see if you can automatically connect then with the quick setup.
