Was this the driver they told you to install?

Windows 7 needs the F6 chipset driver to be installed first before any other drivers can be installed.  In some OEM disks, it is not already included in the installation and will need to be installed manually.  If you can't get internet on this system, you'll need to install it onto a USB on another system and then plug it in to your AW system. 

@Allmightyballsgo to Device Manager and look for an unknown network/Ethernet controller.  Device Manager should open in a way that unknown devices are already shown by default rather than you having to expand any category to find them.  Open the properties of the unknown network/Ethernet controller, go to Details, and select Hardware IDs in the dropdown.  Post the 4-character VEN and DEV codes you find there on this thread.  That will help identify which network card you have (since it seems that system shipped with multiple options) and therefore the correct driver to install.  You will of course need to get to another system that has Internet access to actually download the driver, though.  Hopefully that's not an issue.

Or if you're doing a clean install, you might really want to just consider installing Windows 10 even if it means buying a license (although some are reporting that Microsoft is still allowing free activations on Windows 7 keys).  The reason is that Microsoft will stop providing security updates to Windows 7 in January 2020, and if XP's demise is any indication, browser vendors will stop providing updates to Windows 7 systems shortly thereafter, at which point the system will arguably become unsafe to use on the Internet and might eventually stop working properly as it doesn't get updated to support new Internet standards and technologies.

But if you're adamant about sticking to Windows 7, once you get Internet connectivity, you should manually download the updates below rather than just kicking off Windows Update.  Windows 7 SP1 is very old by now, so if you don’t do this, you could spend many hours installing hundreds of updates over several reboots, in fact nowadays it can take hours for Windows Update on a fresh SP1 install to even figure out what needs to be downloaded. The updates below will avoid that. Just Google the KB numbers to find the download links. This assumes you're starting with SP1 already installed, otherwise download and install that first, then install these updates in this order:

- KB3020369: April 2015 Servicing Stack Update (required to install subsequent updates)

- KB3125574: Windows 7 Convenience Update (takes you from SP1's February 2011 state all the way to April 2016 in one big package rather than hundreds of individual updates)

- KB3172605: July 2016 Update Rollup (includes the fix for very long Windows Update scan times, so after installing this, you may still have a few dozen updates, but at least you won't be waiting potentially hours for them to even start downloading).

@Amjoctthe F6 driver refers to the Intel Rapid Storage driver.  If that were required and not available, the OP wouldn't even have been able to install Windows because Windows Setup wouldn't have seen the hard drive.  Given that Windows did install, that driver might benefit from being updated, but it definitely wouldn't prevent network connectivity.

@Allmightyballsas an alternative to my suggestion above if you really don't have access to another PC to download drivers and copy them onto a flash drive to bring them to your rebuilt system, if that system came with Windows 7 from the factory and that resource CD you have contains drivers, there's absolutely nothing wrong with installing drivers from there.  They will certainly be very outdated by now so you'd want to update them later, but they'll at least get you going.  And absolute worst case if it does somehow mess up Windows, which again is hugely unlikely if the system came with Windows 7 to begin with, then you can just perform another clean install.  It's not like a Resource CD is going to fry your hardware.

No when I called they sent me Dell Wireless 375 A00 R289410. It seems to be the Bluetooth driver but upon usb install it didn't fix anything including bluetooth 

I took a picture to show exactly what Im seeing. I have been on Windows 10 for a bit too long. I also would prefer to upgrade to it but theres an issue but Im not clear on why or what.  I had window 10 Pro, working but then I cleaned the fans(pressing the power button with the battery out) and after turning it back on it gave me so many issues I couldn't get any answers to fix. After a month of getting no where all I was told was my M17xR3 isn't compatible with Win10 features hence the blue screens. I also couldnt not get any form of Win10 USB tool to work during the attempted fix of the blue screens or I would have just wiped it & started over fresh..Something about a media ID(Dell tool wont recognize my key either for camaptibility reasons)Id love to go back but need to make sure it would be a smooth transition.

The disk does have SP1 written on it.

Just to be clear. Since I have SP1 Start with the first KB updates & install in order going down the list? Ill definitely give that a try once I get the internet working. Im also not exactly sure where to start with the net driver install, I get the USB transfer but it seems what Ive installed before isn't correct so I removed them all before postingMissing Drivers Screen shot

@Allmightyballs  that system was also available with other WiFi/Bluetooth card models.  If you post the VEN and DEV IDs from Device Manager that I mentioned earlier, it would be possible to look up the specific WiFi card you have and therefore provide the correct driver.  Or again you could try the Resource CD.

I got impatient last night & tried using the resource CD but nothing happened. I didn't try this before because I saw several posts about how using it will not only take hours if it works but it somehow has a connection with the lights & an Alienware program that will require a fix or new motherboard due to a possible short circuit. 

I found several forum posts about this while googling why the DVD wasn't installing anything

Unfortunately uploaded images are initially visible only to the person who uploaded them and to Dell moderators until they get "approved" for general viewing, which is partly why I asked for just the 4-character DEV and VEN codes rather than a screenshot.  But yes, once you get your drivers installed, you'd work your way down that KB list in order if you've already got SP1.

The Resource CD might just be a bundle of drivers that you'd have to install manually as opposed to having an integrated installer that does everything for you.  I'm not sure since I haven't used one in forever.

As for Windows 10, I'm not sure what was going on with the Win10 USB tool, or for that matter what tool you were trying, but the Microsoft Media Creation Tool will allow you to create either a bootable Windows 10 DVD or a bootable Windows 10 flash drive.  It is certainly possible that the specific flash drive you were trying to use was a problem -- I've seen cases of systems being able to use but not boot from certain flash drives -- but in general if you've used the Media Creation Tool to prep the flash drive, you should just be able to just have it connected when the system first starts, then press F12 to access the one-time boot menu, and choose to boot from USB.  To do a fully clean install, when you get to the Upgrade/Custom choice, choose Custom, then at the page that lists any existing partitions, delete all of the partitions on the target disk until that disk shows as completely unallocated space, and then select that as the target.  Windows Setup will lay down the appropriate partition configuration automatically.  And Windows 10 might also have built-in support for your hardware.
