I installed arch linux on my XPS M1530 with relatively little hassle about three weeks ago. I had no need for wifi back then. Now, I do, and it is not working. I followed the arch wiki instructions, shown here with my output:
[01:09 PM][root:/home/redscare]# modprobe iwl4965
[01:09 PM][root:/home/redscare]# ifconfig wlan0 up
[01:09 PM][root:/home/redscare]# iwconfig wlan0 essid "******" key ********** --> sorry for being paranoid
[01:10 PM][root:/home/redscare]# dhcpcd wlan0
wlan0: dhcpcd 4.0.12 starting
wlan0: broadcasting for a lease
wlan0: offered 192.168.1.50 from 192.168.1.1
wlan0: acknowledged 192.168.1.50 from 192.168.1.1
wlan0: checking 192.168.1.50 is available on attached networks
wlan0: leased 192.168.1.50 for 86400 seconds
Then, I try to unplug my ethernet and cannot ping anything, neither my router's ip, or google.com. "iwlist wlan0 scan" returns results, so I know the card is functional.
Please help me, and thank you in advance.
P.S. I have yet to try ndiswrapper, but I would prefer not to use it anyway. If I need to I will though.
