I have got the following problem. I am trying to connect my Ubuntu machine to a wireless network (WPA2 Personal). I am sure that I am providing the correct key, however I am not able to connect to the network. On the other hand there is completely no problem connecting to this network from a Windows machine nor from a mobile device (Android).
Also there is no problem connecting to a WPA2 network provided by a router set up on a smart phone, so this does not look like a hardware issue of an old machine.
Has anybody stumbled upon a similar problem?
UPDATE: After a very interesting discussion with gertvdijk it turned out that this is highly probable that the problem here is that the network I am connecting to. It uses
CCMP and not
TKIP. I am not able to change this, so I am looking for another solution. The wireless card seems to have
CIPHER-CCMP on its list.
EDIT: The output of
lspci -nn | grep 0280 is:
02:02.0 Network controller : Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter [8086:1034] (rev 04)
EDIT: The results of
sudo iwlist eth1 auth are as follows
Authentication capabilities : WPA WPA2 CIPHER-TKIP CIPHER-CCMP Current WPA version : Unknown Current key management Unknown Current Pairwise cipher WEP-104 Unknown Current TKIP countermeasures: yes Current Drop unencrypted: yes Current Authentication algorithm : Current Receive unencrypted EAPOL: no Current Roaming control: yes Current Privacy invoked: yes
EDIT: The results of executing
cat /var/log/syslog | grep etwork | tail -n20 are posted here
EDIT: After executing
dmesg there is a message that "worries" me.
[260.506187] ipw2100: Can't get TKIP countermeasures: crypt not set!
EDIT: The outcome of
sudo iwlist eth1 scan is here. The network I am trying to connect to is named
TheWirelessIAmTryingToConnectTo. All the other network names have been changed by me.
