Sorry I can't help you.  I have the same problem.

I have a Inspiron 6000.  It says it's connected to the wireless network but when I open Mozilla or IE it says there is no internet connection.

It is not the modem or router as my husband's laptop connects fine, as does the desk top.

It shows an error message reference IP address conflict with another computer on the network.

Anyone have any ideas?

tpboom,

 

Did this just happen? If so, did you try system restore and go back to when it worked?

 

Also try opening Internet Explorer, click on tools, manage add-ons, enable or disable add-ons. Disable all add-ons, then close Internet Explorer, wait 30 seconds and open Internet Explorer.

 

What happens.

 

lostcreek,

 

The conflict is with another computer on your network. Someone may have hacked into your wireless network. I suggest that you use these Recommended Wireless Router Settings in your wireless router and that should stop everything from happening any you'll have a nice private network with everything working, again.

Hi tpboom

Internet connection faults are a nightmare to solve, aren't they.

Fault could be anything but you say that your machine tells you that

you are connected to the internet so here is one thing you could try.

1. Press START and then select CONTROL PANEL

2. Select INTERNET OPTIONS

3. Select CONNECTIONS from the top menus.

4. Select LAN SETTINGS

5. If PROXY SERVER is ticked this will interfere with your connection  -  untick it.

6. Press OK  then APPLY then recheck for browser activity.

If this doesn't work then good luck with your troubleshooting.
