I'm new to ubuntu, and haven't used UNIX since my college days in the 90s. I just installed 12.04 and, after the update, it attached to my home wireless network just fine.

Unfortunately, at work no such luck. I tried everything I could think of, and scoured way too many possible answers here and elsewhere. Still no luck.

When I do a iwconfig at work vs. home and do a diff, here is what I get:

$diff iwconfig_office iwconfig_home
5,6c5,6
< eth1      IEEE 802.11abg  ESSID:off/any  
<           Mode:Managed  Access Point: Not-Associated   
---
> eth1      IEEE 802.11abg  ESSID:"Evergreen"  
>           Mode:Managed  Frequency:2.437 GHz  Access Point: 00:1C:10:8E:D5:89   
8c8
<           Power Management:off
---
>           Power Management:on

lspci at home and office are identical.

At the office I have a Motorola 3347 router; at home a Linksys WRT54GS.

At the office I tried 128 bit WEP as well as personal WPA/WPA2. Neither would connect.

iwlist -scan (note that wyolution2 is the connection I'm trying to use):

eth0      Interface doesn't support scanning.

eth1      Scan completed :

Note: I have half a dozen devices connected to this wireless access point already, including Android devices, W7 and W8. In addition, this specific machine had connected to it in the past before being re-purposed as a Ubuntu box.

Any advice would be much appreciated!

  • Have you got a phone or other device to try the WiFi on. The issue might not be with Ubuntu, it could be with the WiFi at work. Let me know what happens. – illage2 Dec 17 '13 at 7:55
  • Please run iwlist scan at your office and add the output to your post using the edit function. – drc Dec 17 '13 at 8:04
  • Info and responses were added to the original post above. Thanks. – Jared Dec 18 '13 at 14:52
  • In reading out there it seems like it might be related to TKIP encryption, and ubuntu's lack of support thereof. Anyone know if that could be the case? – Jared Dec 19 '13 at 4:36

In case anyone is reading this thread, I wanted to update with a resolution. I moved my system to 3.10 and wireless WPA/TKIP is working fine.
