- high latency at boot time- failure to connect to wifi network at boot time- high rate of connection drops (every 2-5 min)- crash while going on suspend mode- sometimes the wifi config panel would crash the system- the first driver provided on the cd-rom with the device made the system crash at startupOverall, having to reboot every 5 minutes makes this device completely unusable. I have bought this device on the Internet since its not sold in my country and Wifi adapters for Mac are quite rare. When I called the D-LINK US support, the guys refused to support me because I was calling from outside of America ! And they pretend to be a global company !When I contacted them by email, the only answer they could provide me was to reinstall the latest drivers (which I was already running).DWL-122 = Buggy drivers + inefficient technical support
