Windows Vista cannot obtain an IP address from certain routers or from certain non-Microsoft DHCP servers

What virus program are you using?

Rick

Hi Rick,

All the students are required to use the supplied McAfee antivirus.  I disabled but no change.  She has xp sp3 installed.  This computer worked fine both wired and wireless for three months then one day would not log on.  Now that the computer is at home using my network, the symptoms are identical to what she was getting at school.  Limited connectivety due to no ip address.

Cheers,

Ron

Hi Rick,

Ran the winsock fix but she doesn't have a security center on this university version of McAfee.  It's viruscan enterprise and antispyware enterprise 8.7.0i.  Wasn't able to find the internet and network sections.  I tried to log on after the fix but no luck.

Ron

Ron,

Try running WinSock XP Fix

This is for printers but it will allow access through McAfee's firewall.

Allowing Printer past McAfee

1. Open the McAfee Security Center and then click on the ‘Internet and Network’

2. To the right of ‘Internet and Network’ you would see all the services that are present under it, just below that you would have a button ‘Configure’ please click on that.

3. Now you would have the Internet and Network Configuration, in this window you would have an option ‘Firewall Protection in Enabled’ to the right of that you would have a downward arrow, click on that.

4. Then click on the ‘Advanced’ button which would have a new screen up.

5. To the left of that window you would have ‘System Services’ click on it and to the right pane of the window you would have the ports listed.

6. Please check the option which is for ‘Windows File Sharing’ then click on ‘Apply’ and then ‘Ok’

7. Restart the computer

Rick

Ron,

When it tries to connect to your network, then run an ipconfig /all log and post it back here.

Can the computer connect next to the wireless router?

Make and model of the computer is helpful XP SP3, correct?

Make and model of your wireless router. What type of security and channel are you using?

Rick

Hi Rick,

Computer, a Dell Inspiron 1501 with xp sp3,  is sitting beside the router but it won't connect hard wired either.  Router is a Siemans Gigaset 567 with telus.  I'm on channel 11 using WPA-PSK AES.

Thanks for helping Rick.

Ron

Ron,

Start, control panel, network connections

Top should show something like wireless network connection. Right click on the connection. Is it enabled? Left click on properties.

Go down to Internet Protocol (TCP/IP), then click on properties. Settings should say...

Obtain an IP address automatically

Obtain DNS server address automatically.

I would make a new SSID and use these Recommended Wireless Router Settings I use channel 11. Not sure if all the adapters, especially the older ones will connect to WPA-AES. I have my old Dell Inspiron B130 connected using the recommended settings.

Rick

Hi Rick,

I made all the changes and no go.  Her computer always logged in wireless before she left for university with the old settings.  These changes are all geared to wireless, are they not?  I can't log on with the NIC cable either.  If I try the repair option it comes back that the ip address renewel couls not be completed.

Ron

Ron,

Do you have enough available ip addresses on your wireless router?

NOT using Mac address filtering, correct?

Did you try the Recommended Wireless Router Settings I use channel 11.

Rick

Rick,

Plenty of available ip addresses, not using mac filtering, and router was reset to the above recommended settings although as mentioned earlier, the laptop was able to connect using my old settings before she went to university.  I have had numerous devices connect recently, none with any problems.  Pretty certain the problem lies with the laptop in some way.

Ron

Ron,

Try using this and see if it helps. Seeing an ip address not being obtained.

How can I disable wireless configuration services and enable the Windows XP Wireless Zero Configuration services

Hit the Windows key and the R keys at the same time. Type

cmd          Might be       command            for XP

Type

ipconfig /release

Hit enter. Type

ipconfig /flushdns

Hit enter

Restart your computer.

Rick

Rick,

I did all this before changing the router settings and just did it again using the new settings, with no luck.   When I go into my LAN status, it shows "invalid IP address" and if I try the repair feature it says it can't repair the problem because it can't renew the ip address.

Ron

Ron,

The person that knows a little more about this is away on a trip.

I would like to say, make a system restore point. That way if this doesn't work, you can come back to what you have.

Download the drivers for your adapter. Save them to your desktop.

Go to device manager. Right click on the adapter, then left click, uninstall.

Restart your computer. The new hardware wizard should find the adapter and it the drivers are already installed, then adapter would reinstall and possibably work correctly. If it doesn't find the adapter, then install the drivers.

Rick

Hi Rick,

Happy New Year!

Did all the above.  Still the same. :(
