I've set up a bunch of networks without problem, but this one is turning out to be a doosey... It's simple in principle - there's a cable modem on one side of the house and an iMac G5 on the other. Based on the distance of these machines, you'd think that a simple router would be sufficient, but it's not. The signal (from their Belkin) is weak and inconsistent. So I set up a Belkin range extender in between and while it helps a bit, the signal is still inconsistent and often weak. I'm guessing at this point that there's some sort of interference going in in the house and indeed, there are some appliances in the path, though the range extender bypasses them somewhat. Can anyone recommend the next step? Is there any reason to believe an Apple Basestation plus Airport Express would produce better results? Is there a decent antenna which could be attached to the iMac G5 for better signal strength? Which would you try first? BTW, the problem isn't the iMac itself. The same problem existed for the older iMac, as well as two laptops I've tried in the same room. Also, the Belkin router gives great reception in other rooms in the house. I do suspect that the Belkin range extended might be a POS though. Any advice would be appreciated!
