Difficulty getting my network card to work.

j0nbiz · 2015-04-06 02:01:47

Hey there,

I recently converted to arch after the recent kernel update and currently love it. However, even though my network card should be supported, I'm having trouble connecting to any network, whether it be from ethernet or wireless.
I was able to connect to a network through ethernet during the install but not anymore.

I'm rocking a MSI GP60 2PE Leopard using the most up to date version of arch.

I might be missing a lot of info but this is the first time I'm posting for help.

Any help is appreciated! Thanks in advance.

Welcome to the forums. Please use code tags when posting command output - and see the stickied threads in this subforum and the forum etiquette guide on the wiki.

Your ethernet cards is found by `lspci` and `ip link` - all seems in order there so far. What have you done to try to connect? The simplest test would be the following:

sudo dhcpcd enp3s0

If that works, then all is well and good, see the wiki on how to get connected automatically at start up. If the above command fails, please post the error messages it provides.

For wireless, lspci doesn't even show any wireless hardware - perhaps it is a usb interface for the wireless, what is the output of the following:

dmesg | grep usbcore

Hi, sorry for pasting text in such an unorganized fashion.

I got my wired connection working using,

sudo dhcpcd enp3s0

However,

$ demesg | grep usbcore

[    0.754346] usbcore: registered new interface driver usbfs
[    0.754359] usbcore: registered new interface driver hub
[    0.754398] usbcore: registered new device driver usb
[    1.332330] usbcore: registered new interface driver usb-storage
[    5.558350] usbcore: registered new interface driver uas

I also got this while fiddling around,

$ iwconfig enp3s0

enp3s0    no wireless extensions.

Would this suggest that I do not have the required firmware installed for my interface to work wirelessly?
And if so how would I proceed to fix this?

Oops - I may have grabbed the wrong command from the wiki - `lsusb -v` is the right one for checking whether there is a usb interface wireless card. Note that enp3s0 is your wired interface, once you have the right drivers loaded for wireless a new interface will show up that you can use iwconfig with: using iwconfig with enp3s0 will never work.
