Recommendations for USB WiFi Adapter

This one's pretty nifty:

Good point - missed that.

I have used other D-Link products with various Macs but not this one in particular. If I were in your shoes I would take my Mac with me to the store and try it out before purchasing.

Try AftertheMac OS X G54SL+ USB Wireless. I have not tried it myself but have just ordered it. Others say it's good.

usb wifi adapters that use a ralink chipset are known to work in leopard.

Someone who suffers with Apple's airport cards wrote on one discussion group that he bought it and that it worked well. I am sorry I do not remember the site or the group name. I think it was an official Apple discussion group. But if you google a bit I am sure you'll find something.
I considered but did not like the idea of buying an option for which I need to look for drivers around (like what was suggested with d-links). This one sounded as the fastest way to get a strong, reliable and leopard compatible solution without extra effort and time (which I do not have). I guess I will not know if it really works until I try it myself. I expect mine to arrive in a several days.
Sorry I cannot be of more help.

Sure, I'll do this.

Here is something that does not seem very encouraging:

I do not have problems with having a week signal. My MacBook does not reconnect to the network after waking from sleep and when I try to reconnect manually it fails to connect to the network. I hope this USB wifi adapter will do a better job.

Hello.
So, I have received G54SL USB wireless card. Installation was simple but I still needed to install it twice before it worked. Installation indicated that it was for Tiger even though I choose 10.5 package. Setting parameters was easy enough.
So far I tested it on my MiniMac which is placed in a distant corner of my apartment where reception with AirPort card was not very good.

My impressions: the reception with G54SL was better than with the Mini's airport card. I plugged it directly to the Mini, without extension cable. This suggests that I could have even stronger signal if I move USB around when connected to the computer via extension cable. The signal was stable with time.

When computer waked up from sleep it reconnected fast. However, when I restarted computer I needed to choose my network again. It took some time before the connection was established. I did not read manual yet and I do not know if I can make card remember my network and reconnect automatically.

I would say that if you need to extended range and have stable connection this card is more reliable than the built-in Airport card (at least in my case). I still need to try it with my portable computers and test behavior with networks other than mine. I'll try this during the next week.

I wonder about it being a "hardware failure" -- I just bought one and I now get a kernel panic at least a couple times a day. I think it's a software incompatibility. Which stinks because I really need an external wi-fi connecter to get a signal in most of the RV parks I travel to.

I was hoping Hawking would do an upgrade of their driver, but if they don't think there's a problem there I guess that won't be happening.
