Greetingz!
You're running the "Initial Release" of Solaris, which is seriously lacking in hardware support (comparitivly speaking. You may *really* want to consider downloading the latest release ("Update 9" - Released Sept 2010). Maybe even the latest patch bundle (if your entitlements are up to date).
With that being said, there are currently only seven WiFi devices on the
Solaris HCL, your WiFi card isn't listed;
Code:
1. Linksys WMP55AG PCI
2. Atheros AR5005G On-Board
3. D-Link DWL-G520 PCI
4. Atheros AR5212 miniPCI
5. Intel Pro/Wireless 2100 LAN miniPCI
6. Intel Intel Pro/Wireless 2200BG On-Board
7. Senao SL-5354MP miniPCI
The only WiFi card in the above list "Reported To Work" for Solaris 10 03/05 is the Senao SL-5354MP miniPCI card. You might have had better luck with OpenSolaris, as they seem to support
more devices, however the OpenSolaris group was recently
shot in the face and
left curbside in the ghetto
by Oracle (I will admit that OpenSolaris was kinda askin for it).
You can give their last build a shot (or try one of the spinoff projects) by visiting
their download page.
