Default getaway is not available + Local area connection doesn't have a valid IP configuration

[l3ig0de]

Recently, my laptop is having a bit of trouble connecting to a wired connection. Wireless works fine, but wired connection is always having this "Local area connection doesn't have a valid IP configuration" "The default gateway is not available" error. After I run the troubleshooting it says that is fixed. But shortly after, it reappears, and sometimes, I run the troubleshooting again and it says that nothing is wrong.

Things that I've already tried:
> Replacing the ethernet cable with a new one.
> uncheck the "Allow the computer to turn off this device to save power" checkbox.
> Restarting multiple times
> Restarting the routers
> Setting up the static IP
> Disabling IPv6 and other useless stuffs

Network adapter Local Area Connection driver information:
Description . . . . . . . . . . : Broadcom NetLink (TM) Gigabit Ethernet
Manufacturer . . . . . . . . . : Broadcom
Provider . . . . . . . . . . . : Broadcom
Version . . . . . . . . . . . : 15.6.0.14 ?
Inf File Name . . . . . . . . . : oem6.inf

I haven't tried updating the drivers since I don't know what to do with these 3 files from their site. Please, give me instructions and if possible, other possible (definitive) solutions to this problem.

Any suggestion is greatly appreciated

EDIT: My brother's computer works fine.

I found an older post with the same issue.....see if any of these help: "Wi-Fi" doesn't have a valid IP configuration

Find the IP of the router and use that as default gateway?
