I have an IMAC G5 running OSX ver. 10.4.11 (1.8 ghz PowerPc G5 processor) and cannot get it to recognize and interface with a newly purchased Verizon 4G MIFI hotspot. I keep getting a screen asking for a wpa pre-shared key designation. I have tried the MIFI password, SSID, and the encryption number located under the unit's battery with no results. Any help would be greatly appreciated. Thanks in advance for your reply. Larry v.
