Yeah, I set it back to auto when I went to work.

So with the same settings as yesterday when it worked at my office, today it did not.

If its just the wireless network in your office that you can not connect to via DHCP then there isn't really anything I can do for you I will have to be brought up to the IT department again. If its not working via DHCP on your home network we need to look into why.

On the chance its your card you could follow the directions below and reboot your PC.


1. To open a command prompt, click Start and then type CMD in the Search programs and files.
2. Right-click CMD.exe icon in Programs and choose Run as administrator.
3. When the User Account Control box pop up, click Yes.
4. At the command prompt, copy and paste (or type) the following command and then press ENTER:
5. netsh int ip reset c:\resetlog.txt

Ah, yes, the mythical "nets int ip reset" that I have read about on the vast tomes of the interwebz. Flushing/resetting all settings and starting from scratch sounds good, but you can see that it is not "just the wireless network in...office," as the problem reared its head when I took it home.

It worked in my office on auto everything (as an admin).

It then did not work at home. I set a static IP and it worked at home.

I took it back to the office, removed static IP and set it back to auto everything (same settings as day before).

No longer works in office.

Just got home. Auto doesn't work of course.
Gave it the static IP settings - it works at home.

So, for whatever reason, it isn't working with auto settings at home or at work. My assumption (I'm going to take it to a cafe in the next hour and try it there) is that the hardware has an issue - though wouldn't it be nice if an IP reset all would fix this?

I'll try that, just for giggles.

$10 says my coworkers with these same machines/networking cards have the same problem.

Also, thanks Chev65 for the screenshot, that looks just like mine and will help me verify if DHCP at home is on in the router.

Phew.

SO MUCH ADVICE!

I am going to troubleshoot this on Sunday when my work training is behind me.

I just want to say that I really, really appreciate all your help so far - it has kept my hair in my head (not pulled out).
