littlespoons,

What virus program and firewall are you using?

I have the same problem, it started couple of days ago, no connectivity at all.

If anyone has experienced this or knows what might be causing it, any help would be greatly appreciated.

I'm running McAfee antivirus (up to date), and also recently installed some automatic updates.

Thank you for your help!

I have the same problem. Similar configuration to above user. Also, i noticed that my Dell XPS can see network and my router sees Dell XPS however, no internet connection. I tried connect using wireless same result.

Tried to uninstall/reinstall dell network drivers with same result. I checked Windows Update that were installed lately. Nothing was installed in the last two days when I lost connectivity.

Thanks in advance for any help

That is also what happened to my laptop. I JUST got my laptop not even a month ago. I have my own router and the other computers and laptops and phones connected to WIFI in my house are connecting fine. It says it is connected to my WIFI router's name but it says that there is no internet activity. If anyone knows how to resolve this issue, the answer would be greatly appriceated.

Also, all other computers on my home network are connecting to the internet without any problems.

I uninstalled McAfee and it fixed the problem. Apparently there is an issue with McAfee. I also found out from Dell Support  that McAfee caused an issue with Dell hardware and they will send a technician to replace defective part. So I suggest for all of you who have a problem similar to my to contact dell support so they can do the same for you.

I was able to isolate this problem to McAfee Antivirus that came with my laptop. When I log into safe mode with network support I get internet connection. I remember that there was update recently to McAfee. Maybe this is when the problem started. Will keep you updated as to my findings

PaigeEatsPandas,

Try system restore before Saturday night. If you still have connection problems, create a new thread in the Dell Networking, Internet, Wireless Forums

Your solution was absolutely spot on.  I uninstalled McAfee and then reinstalled; everything was up and running AND with internet connectivity.  All is well with the world once again!

Thanks for the info.
