Software Updates Causes Wireless Connectivity Issue Or Unable to Connect to Internet

 

 

Use system restore to before Saturday night, and your connection should come back.

 

Then Update McAfee.

Restore did not work even going back 3 or 4 restore points.  In my case it was the "New XPS 15" and it was actually brand new.  Opened on Aug 17, worked fine until Saturday Aug 18 and researched this Forum and other places with nothing found.   The solution to Fix this:  Uninstall McAffee and the internet connection works, but your computer is vulnerable now.  Go immediately to www.mcafee.com and sign into your account, and you can select to reinstall. The whole fix took about 5 minutes.

Dear support, you need to get in synch with your help desk.  They provided this link http://service.mcafee.com/faq/TS101446.htm and stated to go directly to Step 3.  Bottom line is Uninstall McAfee, internet works again, go back to www.mcafee.com log in and reinstall McAfee.

I did not have a restore point so it was impossible for me to restore the system! 😞

Thank you so much!

If McAfee ruins the connection to internet, why should I re-install it?

Thank you so much!

it was a bad update that McAfee published, then they fixed the update.  You could not received the new update because your computer would not connect.  When you reinstall, it will be a good clean version of McAfee.  I'm assuming you've paid for McAfee or it came with your system, so you paid one way or the other, so take advantage and McAfee is a good Antivirus program. emoticon.Cool.title

Re: McAfee DAT Update Causing Internet Connectivity Issues for Some Users

I have just experienced major problems connecting to the internet which I thought was caused by a problem with my internet router. The company that supply my phone/internet service provided me with a new router and of course this did not work once I had connected everything up. It was on contacting Dell that I found out the problem being caused by McAfee's latest update. Fortunately the Dell representative solved the problem for me. However, the problem also affected Mozilla Firefox on my pc and it was only through the help of a friend of mine in Germany that I was able to get various regular websites that I use back to their normal function. 

I have since removed the McAfee anti-virus software from my computer and have purchased Norton 360. I used Norton on my old pc and never had a single problem with them. Given the problems that appear to have occurred previously with McAfee I am wondering whether Dell should be recommending this anti-virus software.It will certainly have caused Dell employees to have been engaged in many man hours to sort the problem out. Will Dell be seeking compensation from McAfee?

The service I received from the Dell representative was first class and I am pleased to say that my desk top computer is now functioning normally.

I agree. I have removed McAfee from my desk top pc and installed Norton. The problem caused by McAfee meant that I was with internet connection for almost a week. How was I to know about this problem if I could not connect to the internet? No doubt you have found an alternative to McAfee by now.
