WiFi connected, but no traffic

zoran119 · 2013-02-27 09:23:49

Hi all,

I have just installed Arch on my Dell XPS 14 Ultrabook. I use wifi-menu and it says that it successfully connected to my WiFi. However, I cannot ping anything (not event the gateway, it just sits there until I kill it with ^c).

However, I created a hotspot on my android phone and the laptop connected to it and I could browse the net.

Some diagnostics are included below. Any idea what might be going on?

First of all, try to connect it manually ithout any frontends.

Use iwconfig to connect your laptop to the SSID you want, and then launch dhcpcd on the wireless interface.

Post anything suspect.

And, yeah, try the to connect an other device to your router too. (Your phone, for example).

I changed the security mode of my WiFi to WPA2 (as opposed to WPA/WPA2-PSK) and all is well now.

zoran119 · 2013-02-28 22:34:00

I was wrong... it is not all good. Very intermittent. Works if I disable WiFi security completely. Any ideas?

Is wpa_supplicant installed along with the other stuff?

zoran119 · 2013-03-01 10:22:01

Yes, everything is running (see the code I pasted in the first post). I can connect using wicd, NetworkManager, from command line or wifi-menu. I get an IP address every time. But no traffic at all about 90% of the time... I keep rebooting and then eventually it works... Have no idea where to start...

Changed the WiFi network from channel 11 to 6 and it is all working now... go figure.
