WiFi connects but can't reach anything.

Hello, everyone.

I have a strange problem. On Friday, my ISP gave me a new modem and router along with a different internet plan. Everyone in my household is able to use it without issue. However, on my system, I can connect successfully to the network but I can not reach anything (including the router's IP and web interface). Today, it successfully connected and worked on boot despite me not modifying any settings. A few minutes ago I rebooted and the issue is back. I have taken a look at netctl's systemd log and journalctl but there are no error messages displayed or anything that appears to be out of the ordinary. I honestly have no idea what the issue is and would appreciate any advice.

P.S.: I apologize for any grammatical errors. I am typing this from my tablet.

Re: WiFi connects but can't reach anything.

Just to test, figure out what IP-range your router is supposed to hand out. My router at home does this with 192.168.0.* . Some routers use a 100 or 1 instead of the 0 on the third position. Once you know that, try to manually assign an IP-address to your Arch machine. Of course this means dhcpcd is of no use to you, but it might work for the moment.

All devices {including mine) are have an address that is in 192.168.1.*.

It was working fine again yesterday for a brief period but is back to normal today after rebooting.

Re: WiFi connects but can't reach anything.

I see three things having to do with networks. 

/etc/systemd/system/multi-user.target.wants/netctl@internet.service
/etc/systemd/system/netctl@internet.service

I don't think the second one belongs.  Are one of them a link to the other?  If not,  is one a copy of the other?

Re: WiFi connects but can't reach anything.

The second one is the original and the first one is a symlink.

Edit: It was created with the command netctl enable internet where internet is the name of my netctl profile.

Here's my systemd status of netctl as well, in case it helps at all.

From what I can tell, there's no errors and my device shows up as connected on the router's web interface.
