I bought a Dell Vostro 2520 two days back and when I clicked wifi icon to connect to my wifi network, I couldn't see mine or any other wifi networks. So I then realized that I need to install a driver so that I can connect to my Wifi network which is Broadcom STA wireless driver. I tried activating it but then an error came on the screen that said
Sorry, installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log
So then, I tried connecting to my wired connection. But there are a few problems.
I clicked on IPv4 Settings and set the method to Automatic (DHCP). I could get my IP Address and my Netmask but not my Gateway address and my DNS server.
I tried getting my Gateway address by Terminal but all the answers were blank so I couldn't get my Gateway Address.
Kernel IP routing table
Destination blank Gateway blank Flags Metric Ref Use Iface
I also can't get my DNS server cause I have no internet connection. I tried everything I googled to resolve this problem but nothing seems to work. All I'm getting are errors.
Okay so now the Wired connection shows that it's connected but it's not connected. I did the command @chili555 told me to and here is what it says:
07:00.0 Network controller : Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)
09:00.0 Ethernet controller : Realtek Semiconductor Co., Ltd. RT8111/8168/8411 PCI Express Gigabit Ethernet controller Controller [10ec:8168] (rev 07)
Now that my Wired connection shows that it's working but it's not, I got my Gateway address and my name server. I added them in my wired IPv4 settings. But my internet connection isn't working still. :(
YAY! It's fixed!! Wired and wireless connections are fixed! Thank you so much! :D
