Hi

I recently got myself prebuilt Hackintosh on Advent 4211 running Leopard 10.5.6. I loved browsing net using the wireless provided through the RealTek WLAN Client Utility but from few days, its not recognizing/detecting the wireless connection , I have one more machine running xp which is easily detecting the wireless connection from my router.( At least my router is working fine .. phew). Seeking help ?

P.S Am a newbie to MAC but have a fair knowledge about computing
