Drivers are never needed for a Router. A router will always be accessed via a web page. You can determine the web page to go to by looking at your IP settings.
So if you execute the command
ifconfig you get an output like
eth0 Link encap:Ethernet HWaddr 90:2b:34:36:50:55
inet addr:192.168.1.144 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::922b:34ff:fe36:5055/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:68090 errors:0 dropped:0 overruns:0 carrier:2
RX bytes:124193612 (124.1 MB) TX bytes:6263115 (6.2 MB)
This tells me web address is very likely to be at
http://192.168.1.1 which is the lowest address for your segment.
As to internet not working first connect without router to see it works, which it probably does. then plug the cable into the WAN port and your computer into the LAN port on the back
