I have 3 laptops connecting to a Netgear router, two are working fine, one running Vista and the other XP, but the third one (XP)won't connect. It was working ok until my daughter took it to university (it worked fine there using a wired connection) but now she is back home it won't connect to the home network. It recognises the network but won't connect!

Can anyone please provide any advise to rectify the problem?

Any help would be much appreciated.

She probably changed her TCP/IP settings to get on her University Network make sure her TCP/IP settings on her laptop are the same as the other computers on your network that can connect. If you have checked in your TCP/IP setings to "Obtain an IP address automatically" and "Obtain DNS automatically" then thats what she needs to have as well. These instructions will help you access your TCP/IP properties.

Many thanks for the reply and advice. I will check that out when I get home.

[mike171562]

if that doesnt work check her proxy settings in her browser, many schools and universitys use web proxys to filter internet browsing for students.

Will do. Thanks again.

I followed the instructions, and changed the DNS part to automatic connection. Everything then worked and I was connected, but after about 10 minutes the connection broke.

Windows finds the Netgear router but won't now connect to it again. Before I made the change to the TCP/IP settings the symbol on the task bar said it was connected (although it wasn't) but now there is a cross through it. The proxy settings are ok and I can't think what to try next.

Any suggestions gratefully received.

Try selecting "obtain ip automatically" and Use the following DNS servers and enter the two addresses below.

156.154.70.1
156.154.71.1

[AllanOK]

Thanks - I'll try that.

[AllanOK]

Still no joy.

As the laptop was working ok before it was taken to Uni., do you think it worth reinstalling Windows to get the settings back to where they were before?

If you want to reset your networking settings, you can just re-install the network driver for your wireless device.

[mike171562]

you can reset your tcp/ip settings. by doing the following. click on start -run and type cmd, then press ok. You will get a command prompt, type the following


netsh winsock reset press enter, then type
netsh int ip reset resetlog and press enter and reboot.

to test your connection from the command prompt try typing "ping google.com" without the quotes. Do you get replys? if not then type "ping 74.125.67.100" do you get replys? if you so then its a DNS issue.

[AllanOK]

Thanks for those replies - I'll try each in turn and see how I get on.

I haven't tried to re-load the drivers yet as I couldn't find them for this model on Acer's website. I followed Mike's suggestions and got a reply when I pinged google. The internet was then working although the connection symbol on the toolbar said it was not connected, but after 5 minutes or so it stopped working again. Very confusing!!

A friend has suggested using Intel Proset to manage the wireless connection but I can't find that programme on the computer - should it be there as part of XP?

Again, any help/suggestions greatly appreciated.

When it stops working you need to find out why it stopped working, what changed. If you got it working at some point, your settings are correct, but something is changing, you need to find out what that is. Are you dropping the wireless signal? Are you losing your IP address information, start - run - type cmd press ok, then type ipconfig /all If your losing your TCP/IP settings, try finding out what they were when it worked, and enter that information statically.

[AllanOK]

Thanks again for looking at this.

I presume I must be dropping the signal but I don't know why - the other laptops in the house are working ok.

I have done the Ipconfig thing and the result was:
