Router Security

[hhawaner]

Hi everyone, Im having trouble with my router on Ubuntu. I have had to reduce my security to WEP. I prefer WPA2 but cant get Linux to log on to the wireless with WPA2 set up. It recognizes a WPA2 enabled network but when I put the password code in it wont connect. WEP connects ok. Any advice would be very welcome. Thanks in advance. Scott

Hello and welcome!
Have you tried installing or configuring wpa_supplicant? It's needed for WPA enabled routers.

I tried to install wpa_supplicant & it said it was already installed. It recognises that it is a WPA2 connection & I have the screen to enter the password but when entered it doesnt connect to the network & the password screen pops up again. I have set the router with a passphrase. I assume linux uses the same encryption methods???? How do you configure wpa_supplicant?? Many thanks in advance, Scott

On Gentoo, you configure wpa_supplicant in /etc/wpa_supplicant/wpa_supplicant.conf a lot of distros use this path/etc/wpa_supplicant.conf
Here is mine (editted) for reference.

# This is a network block that connects to any unsecured access point.
# We give it a low priority so any defined blocks are preferred.
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
  ssid="SSID"
  proto=WPA
  key_mgmt=WPA-PSK
  pairwise=CCMP TKIP
  group=CCMP TKIP WEP104 WEP40
  psk="xxxxxxxxx"
  priority=2
}

Ahh. I havnt got a wpa_suplicant.conf file to look at. Theres a Wpa_supplicant folder with only 2 files in it. functions.sh & ifupdown.sh. Does that mean its not installed properly?

No, it means you might want to create that file and do some reading on WPA security.
it's just a text file with the contents as posted above.
