No Internet on Cold Boot?

I've got a brand new M15x, right out of the box.

It's connected to a network with an ethernet cable and can access several wifi networks in the building; both connections function fine.

However, every time I turn the laptop on, it 'sees' both connections (even has the right name for the wifi network) and cannot connect to either. If I restart, everything is fine.

I should have up-to-date drivers because it's new, and I just checked the drivers for both wireless and network cards- it says they are up-to-date.

I've found a few threads about this same problem, mostly on this site, but no solution has ever been found in the past. Theories in the past have included something in power options- I didn't see anything in power options about the network card, just the wireless card- and the possibility of the card not booting fast enough for BIOS to recognize it.

I have already tried uninstalling the cards and letting them reinstall on reboot.

Is there anything I can do, or have I been shipped a bad network card that'll be pretty much impossible to replace without paying through the nose and having to live in the campus library for a few weeks to get work done? I'd expect this sort of thing from a cheap netbook, not a laptop that costs over two grand.

 

which wireless card do you have?

also anytime the computer is acting a little glitchy, the first then i would try is a power drain.

-turn off and unplug
- take battery out
- optional is taking out the coin battery too
then press power button for 20 sec.

 

For network adapters in the device manager I have:

DW1520 Wireless-N WLAN Half-Mini Card
Intel(R) 82577LC Gigabit Network Connection

I'm confused about why both always fail, if they're separate cards? It seems unlikely that they'd both be defective independent of each other.

 

Some more info:

-Unlike similar cases reported online, neither card disappears from the device manager. Both report that they are working properly.

-For approximately three seconds after the desktop appears, the ethernet connection can access the internet. (Not wifi.) After those three seconds, it simply says 'no internet connection.'

-Restarting doesn't always fix it. Sometimes it takes 3-4 restarts before I can access the internet.

-Disabling/Re-enabling either card does not fix it.

 

try uninstalling the gigabit driver and only use the 1520 driver.

maybe try doing a clean install of windows.

 

Uninstalled just the gigabit driver and rebooted; now it says there are no drivers / can't find them online or in the system.

In device managers only the WLAN card is listed in 'network adapters'; there is a new category beneath that called 'other devices' which lists the unknown ethernet controller. Is there a way to restore functionality to my ethernet controller?

maybe a good time for a clean install:
