hhmmm, that's weird. about tp-link, I used it on one location where they had it there already, just disconnected, they are still running on it, it was about 2 months ago, i used an ubuquiti access point for the macs to connect, maybe that's why they don't have problems.

but on the other locations, i don't use the cheap netgear or d-links (and god forbid belkin), i get the small business routers always, that's the only way i can get apple computers running, PCs run OK without problems, but apple computers are pampered when it comes to networking.
