Can’t access internet in normal mode

Hi

I recently bought a new Dell XPS Ultrabook 13 with i7 processor. It worked fine for about three weeks, then all of a sudden it refuses to connect to the internet. I am still connected to my wifi network, but the network and sharing centre shows the connection as dropped between the hub and the internet. Troubleshooter offers no answers. I know other Windows7 users have experienced this and so I have ALREADY done the following:

Tried accessing the internet in safe mode with networking. This works, so it is not a hardware issue. I can definitely access this web in this way.

Rebooting my wireless router etc. I know this is not the issue though, as other devices such as my iPhone can still access the web through it (and the XPS, in safe mode)

Possible spy/mal ware. I think this is unlikely. A) the laptop is new b) I am extremely careful on what I download c) I have run repeated full system scans with both my preloaded AV software (McAfee) andMalwarebytes anti-malware. Neither has unearthed anything at all. Not a single item, and they both are checking against the latest databases.

I ran msconfig and deselected all startup programs and services except MS ones. I also downloaded and did similar through ccleaner. No joy.

I checked devices through device manager. All devices seem to be working normally. No conflicts. I disabled and enabled the network wifi miniport adaptors. Again, nothing.

The most frustrating thing is that I haven’t actually made any system or setting changes recently, so I don’t understand how this could suddenly have just happened. My only suggestion is that I downloaded the usual round of MS updates the other day. Could that have affected it?

So does anyone have ideas on how to solve this? I don’t want to spend the rest of this PC’s life accessing the internet in safe mode!

In desperation.

Hi Welcome to Seven Forums.
To help all of us would you please add your systems specs? Here's how: http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html#post1530002
Under System Manufacturer/Model Number add desktop or laptop and whether self built.

You can easily copy/paste specs to your profile from within the app, no install required.
I would get rid of McAfee, it cause a lot of issues in w7. Yes updates can do odd things too. Use a system restore to before those updates then reinstall one at a time.

Thanks.

Will provide spec, get rid of McAffee and run backups ahead if updating future. But that won't help me on this problem as I did do it before the latest update.

Thanks once again

As above, Uninstall McAffee (Use http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe)
then Reset Internet explorer with the following tutorial http://www.sevenforums.com/tutorials/1222-internet-explorer-reset.html

With a three week old Dell, I would first contact Dell support. Most likely they can fix it remotely.

Edit: I just saw McAfee has a problem since update Tuesday with users losing their internet connection.

Get McAfee off your computer and get Microsoft Security Essentials!
