Power Mac G5 Airport can't see any Wireless Networks

Hi, I have acquired a Power Mac G5. The previous owner was using it wirelessly before I got it. Airport is on, but cannot see any wireless networks, yet when I check on my laptop (windows xp) from the same room there are 9 networks displayed in the 'view wireless networks' list (8 from neighbouring houses). I wondered if there was a setting needed switching on or off or whether my Netgear DG834N router is compatible or even if the airport card is kapuut! I have tried setting the system up in the same room as the router to see if distance makes a difference, still no change.

I have limited knowledge of the Mac systems so don't get too technical if you reply.
The details are:Hardware Overview:
Machine Name: Power Mac G5
Machine Model: PowerMac7,3
CPU Type: PowerPC G5 (2.2)
Number Of CPUs: 2
CPU Speed: 1.8 GHz
L2 Cache (per CPU): 512 KB
Memory: 3 GB
Bus Speed: 900 MHz
Boot ROM Version: 5.1.8f7

Hope someone can help. Thank you in advance.

 

Hi, Thanks for the quick reply. No there doesn't seem to be anything like this; does it stick-out very far? And where does it fix to? Regards.

 

Hi, I've been in touch with the seller and this is what he said "All came pre installed and it's the same aerial which is on a laptop two long wires that use the casing as a big aerial, usually standard for mac aiport wifi aswell as the white attena" Is this any help? Thanks.

 

Hi, He does also say he was using it in this way to connect to his wifi. Do you know if these aerials can be purchased separately? Is there one for bluetooth as well? Thanks.

PS. Another thought after reading your link about the aerial; it does say "Power Mac G5 (Late 2005) models have their AirPort and Bluetooth antennas integrated into the enclosure, and do not use the external antennas described in this article." do you think this G5 could be one of those models?

 

Hi, actually it does have 2 ports (holes), 1 for Bluetooth and 1 for wifi. Is this where the aerials should go ? They look similar to 3.5mm jack plug. Thanks for all your advice so far.

 

Ok, I will try something like the paper clip to see if I can get any visible wireless networks . I'll let you know what happens. Thanks again.
