Hi All, Greetings. I am on Oracle Enterprise Linux (OEL 5.5 x86_64) same as Redhat 5.5. I must use OEL5.5 because of my software installation requirements. NetworkManager detects my ssid but its just not getting ip from my router assigned. I use a Belkin 54g router with WPA/WPA2 encryption. The other options available on my router are WPA2 only, WEP and Disabled. I have spent more than 20 hours trying to get wifi working but no luck. Your help is highly appreciated.
