Make and model of Router: Netgear Rangemax duo Wireless-N Router

Hi thomsonblue,

Yes i did mean connecting the Mac to the router with an Ethernet Cable. Would it be possible for you to move the computer into that room just so we can rule out some things?? Because if the Ethernet Connection works without fail then we can deduce that there is an issue with the WiFi controller.

Thanks,

BrendanT

I moved the Mac into the same room and the connection is fine. Maybe I need a wireless range extender? It's just odd that my laptop has no problem connecting in the other room right next to the Mac.

thomsonblue,

Wonderful we have now ascertained that it is infact a problem with the Wireless Adapater Can you confirm for me that you have the latest driver updates? And that you have also updated Mac OSX to the most recent version?

thomsonblue,

please have a look at the following links here and here.

I hope these help. My expertise isn't really in Macs but i will try to assist you as much as possible!

Could you connect your iMac to the WiFi again, open up the Terminal[/b] and run [i]iwconfig. Please post the output here.

I am running the Intel Driver Update Utility...


Excellent!! :)

Sorry, Brendan, but I have no ides what you mean by "open up the Terminal[/b] and run [i]iwconfig".

And do you mean you think it may be a problem with the Wireless Adapter in the Mac and that you want the latest driver updates from the Mac?

Sorry to be so dense!
