I recently imaged Ubuntu a Dell Vostro 3900 Series with an Intel Core i3-4170 CPU @3.70GHz x 4 (32-bit). After installing we do not have internet access wired or wireless.
Referring to this question, we tried: sudo lshw -class network and got the following product info: Product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller configuration includes driver=r8169 firmware=rtl8168g-2_0.0.1 02/06/13
Then created a file config in /etc/pm/config.d/ And entered SUSPEND_MODULES="rtl8168g" and saved Then ran the following command: echo "options rtl8168g fwlps=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
And then rebooted, but it didn't change.
I feel sure you're going to tell us that this is a duplicate question, but it's hard to see what the relevant piece is from all the suggestions offered on the various questions that have some degree of overlap with this one.
Anyway, any help that can be provided is appreciated.
