Yellow Exclamation Point in Device Manager

I'm totally new to this, and I apologize if my post is somehow in the wrong place. I have a Dell Latitude E6420. My computer had Windows 7 and I re-imaged it with Windows 7 (because of a procedure for work, something about removing myself from their network.. I was just following the directions I had been given). Since the re-image, I cannot connect to the internet whatsoever. With a cable or wirelessly. My computer recognized the wireless networks I had at my house before the re-image, but there is no longer a wireless adapter even under my "network adapters." Moreover, every single "Other device" has a yellow exclamation point next to it. I cannot connect to any internet at all to remedy the problem and am at a loss for what to do. Any advice would be greatly appreciated. Thank you!

 

I have moved your post to a new thread; please don't post in old, old threads.

That being said, how exactly did you "re-image" the laptop? It sounds like you just did a clean install, and clearly Windows 7 doesn't have any E6420 drivers by default...

 

thank you...and sorry about the incorrect post. i "re-imaged" it the way I was told to, which was quite literally inserting the Windows 7 disc, and clicking through (using "Custom" instead of "Upgrade")... obviously that must be wrong. I am a total novice at doing this (as you can plainly see)... so your advice is greatly appreciated.

 

Did you install the drivers for your system? Go to support.dell.com, input your Service Tag and download the appropriate drivers.

 

I would... but i cant get online.... at all (connected with a wire or wirelessly). thanks again for trying to help.

 

You can download the drivers from another computer, put them on a flash drive and install them on your laptop..
