This trick worked like a charm. I called D-Link, was sjubected to a techie who didn’t know a Macintosh from a Granny Smith and told me to call Apple. I raised cane. He hadn’t offered a single suggestion, hadn’t even gotten an understanding of the problem but blew it back on Apple. After I acted awful, he relented and “did some research.” I expect he was smart enough to search the web and find this post (my head was up my tailpipe apparently for not doing a good search in the first place). After a few mins, he read the post to me: Log in to router. Click advanced. Click performance. Change from short to long preamble. As soon as I did, by laptop, sitting beside my desktop (which was programming the router) sprang to life. The DHCP number popped in there, the router was assigned, and voila! Internet.

Thanks to the guy who figured this out. I am only sorry I didn’t heed your words before calling DLink tech support. Apparently, if it ain’t a windows box, it must be your computer according to those guys.

At any rate, router works great now!

You are correct, this does get my ancient iBook Blueberry clamshell to talk wonderfully with my D-link DI-514; however, the change I make to the preamble then degrades network throughput for the Gateway laptop that access the network using a D-Link DWL-650 wireless PC card. Have you experienced this? If so, what did you do?

Thank you, thank you, thank you!

I had spent 2 hours trying to get this resolved. I’d been to Apple’s support site, D-Link’s support site, and my forehead was bloody from my bashing it against the wall.

Finally, I googled the right terms and ended up at your page. ONE MINUTE LATER, everything works fine.

Thanks again. Now I’m going to wipe up this blood…

Hallelujah! It’s amazing what a little googling can do… I’ve spent weeks on this… although this was the first time I tried an actual query on it.
