Wireless network detected but will not connect

Hi there!

I have a D-link dir-635 firmware v. 2.30eu (latest) and a USB WLAN adapter D-link DWA-140 802.11n. The driver seems to be installed correctly since lsusb lists it correctly and all the wireless networks in the vicinity are detected including mine. When I try to connect however NetworkManager says it is activating but after awhile the windows with the newtork password appers. dmesg output:

5509.487262] wlan0: direct probe to AP 00:1c:f0:71:03:88 try 1
5509.684014] wlan0: direct probe to AP 00:1c:f0:71:03:88 try 2
5509.884020] wlan0: direct probe to AP 00:1c:f0:71:03:88 try 3
5510.084014] wlan0: direct probe to AP 00:1c:f0:71:03:88 timed out

So it is able to determine the AP:s mac address but each time it times out.

I have tried disabling the security on the router but no luck.

Not sure what to try next. I have checked some of the tips supplied in these forums but none seem to handle the issue I am having.

Any suggestions would be great.

Are you using KDE or Gnome? If KDE, click on the applet, choose “Manage
Connections” and create a connection for your wireless. It is a design fault
(bug?) in the current NM that security information entered into the pop-up does
not get entered into the database.

If you are using WEP, you must use the hexadecimal key. A passphrase is unlikely
to work as there are two ways to convert a phrase to a key, and Linux uses a
different one than Window$.

Hi thanks for the reply. I am using KDE. I have tried disabling wireless security on the router so the wireless network is unsecured then adding a connenction that dosn’t use wireless security but it still will not connect. Perhaps the router dosn’t work with linux?

AFAIK most routers are small linux machines, that’s not where the problem is.

Open a terminal window and post output of:

su -c ifconfig

enter rootpassword when asked for.

I had a similar problem and a tcpdump showed the probes were sent with a source address of 0.0.0.0 causing my D-Link router to reject them as not from the correct network. I never addressed the problem as I connected using a static managed net from the router instead of trying to create a dynamic Ad-Hoc net.

Sounds like either a configuration problem or a routing problem. You are going to have to post your router setup and what you’ve entered into NetworkManager. The output from ifstatus wlan0 would be helpful.

Ok. Now it won’t even detect my wireless network. My windows laptop can detect 6 wireless networks in the vicinity including my own. My linux machine only detects 4 one of whitch my windows machine dosn’t detect. I have tried connecting to another unsecured Zyxel router and it just times out there too.

My router uses automatic channel scan, WPA2 personal with passphrase, auto channel with 20/40 Mhz, Mixed 802.11n and 802.11g mode. transmission rate is also automatic

ifconfig output:

EDIT: My router is detected now. There was a setting in the router for WPA mode. The options were “WPA or WPA2”, “WPA only” or “WPA2 Only” if I set it to WPA2 only Linux was able to detect it.
Still times out though.
Setting in NetworkManager or my connection is:
Mode: INfrastructure
BSSID: empty
Restrict to interface: WLAN0
MTU:Auto

Wireless security: WPA/WPA2 Personal

UNder IP address tab:
Configure Auto DHCP
DHCP Client ID: empty

EDIT2: tried using static ipaddresses but it didn’t even try to connect.

I see no indication that you have authenticated or associated.

Please return you AP to WPA or WPA2, get rid of static IP’s, try to connect, and
post the output of

sudo /usr/sbin/iwconfig
sudo /use/sbin/iwlist scan
dmesg | tail -n 100
sudo tail -n 100 /var/log/wpa_supplicant.log
sudo tail -n 100 /var/log/NetwotkManager
