I have to let this out. I have a DLINK WBR-2310 wireless G router (crap, don't even consider buying it); and I am running 10.5.4, yes, I went back to that for a couple of reasons that I hope you can shed light on. A few weeks ago I upgraded to 10.5.5, and then promptly installed the Airport 2008-004 update, which made my wireless unusable (connection would drop every 10 minutes or so, take 30 seconds to reconnect.) So I did an Archive and Install, the update was removed and I was back to 10.5.4. I installed the 10.5.5 update, and ignored the 2008-004 patch. All was going well, the internet was solid (the connection, occasional drops, but nothing like every 10-15 minutes, more like once or twice a day). Now, 10.5.6 gets in the story. Released a few nights ago, I downloaded it from Software Update, the install went without a hitch, I was satisifed... until I booted back into Leopard, and that 10-15 minute scheduled drop was back, much to my frustration. Now I don't know how to proceed from now on: I thought I'd install 10.5.5, then put in the Airport update that failed for me, then install 10.5.6 and just hope it was a software issue that brought back my wireless drops in 10.5.6, due to 2008-004 not being installed. I have better things to do all day then wait around for an installation to complete and test my wireless, but I just don't know how to continue.
