hi. i am wondering what i need to do to get the network manager applet to display my wireless card and strength ? i have 2 computers loaded with ubuntu 9.04. on the first pc, the nm applet shows the wireless device, and signal strength. i took the same usb dlink wireless modem and put it on the 2nd computer. it does not show any active device, even though i am able to access the internet (so its really just an annoyance more than anything).
on the 2nd pc, i had to enter the essid, key, etc in the interfaces file and enter a default gw route to get the internet working (didn't have to do any of that on the first pc.. it just worked). the 2 pc's are different (one is sony, one compaq), but they both have 9.04 loaded the same, and i was using the same wireless device on each of them.
maybe the solution is to remove the applet from the taskbar, so it doesn't display what appears to be a down network..
any ideas?

i also gave lsusb output, since that is the type of wireless device i use. i don't have a wireless card, just use the wireless usb dongle.

Right, I thought it would give the type of chip inside the dongle and not the name of the device itself. :-k

i don't know much about chipsets, firmware rev, and all that..
here is some info that might apply if i have the A1 rev:
Device Info

* Manufacturer: D-Link
* Model #: DWL-122
* Revision: A1
* Device Type: USB
* Chipset:

ID 2001:3700 D-Link Corp. [hex] DWL-122 802.11b
nic h/w: id=0x8026 1.0.0

* Vendor/Device #: 2001:3700
*

Vendor Link: ftp://ftp.dlink.com/Wireless/dwl122/


i thought prism 2.5 was the chipset, but i don't really know much about that level of detail. i will look at the dongle tonight and see if it lists the rev level.. i think it is A1.
do you think dmesg would show anything useful?
