Can't connect to Wifi router

ephan · 2012-07-27 23:02:28

I always managed to connect to Wireless networks normally. However, today I didn't manage to connect to a Wireless network, but other laptops can connect normally to it (I tried both Arch and Linux Mint on my laptop, and I get the same error).

On my dmesg, I get:

wlan0: director probe to 00:26:5b:58:88:89 (try 1/3)
wlan0: director probe to 00:26:5b:58:88:89 (try 2/3)
wlan0: director probe to 00:26:5b:58:88:89 (try 3/3)
authentication with 00:26:5b:58:88:89 timed out

I get that a ton of times, both on Awesome WM, Gnome Shell, etc.

lspci -vv | grep -i network
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wierless Network Adapter (PCI-Express) (rev 01)

iwlan scan

wlan 0                        No scan results

iwconfig

              Power management:on

dhcpcd wlan0

Important note: yesterday I managed to connect to this network, for like 2 hours, but now I can't anymore, and it's not a matter of location, I've tried several locations/positions including the same one as yesterday.

It's a FON ZON network by the way.

Is that supposed to be iwlist scan
If it is, make sure you run that with root permissions -- otherwise it just serves up extant (stale) data.

Yeah, it was iwlist scan, I also tried "sudo iwlist scan", and it gave a huge output which I can't rewrite right now. It had all the information on the router, ESSID, Mac Address, etc. It seemed fine.

It sounds fine. Is this solved then, or are there problems in the next steps of connecting? dhcpcd is not the next step, and shouldn't be expected to work until you connect to a network.

What seems fine is the information about the router, I can't connect, I get the same error I posted about in the first post :S

What do you mean you can't connect? Show the commands you are using and the errors you get when you attempt to connect. The first post didn't have any of this.

Is your network open or secure? WPA(1/2) or WEP? If it's open you should use `iwconfig wlan0 essid "YOUR ESSID"` as root/sudo. If it's secure[1] you need to use wpa_supplicant, and perhaps wpa_passphrase to get a configuration set up. Without these, dhcpcd should not work.

[1]: this should be for WPA, if it's WEP, you should really consider WPA, but if you stick with WEP, then you'd just use iwconfig with the key.

I am using network manager's applet, it's a security-free router by the way. I am using nm-applet, but when I run "dmesg" after it fails, I get:

wlan0: director probe to 00:26:5b:58:88:89 (try 1/3)
wlan0: director probe to 00:26:5b:58:88:89 (try 2/3)
wlan0: director probe to 00:26:5b:58:88:89 (try 3/3)
authentication with 00:26:5b:58:88:89 timed out
