This D-Link DI-514 wireless router has given me nothing but trouble [never have I wanted so much to throw a piece of hardware out of a window and never see it again], so there was no pain in dismantling the stupid thing for decorative parts (except for the occasional burn from the soldering iron). I have already replaced it with a Linksys, and I'm much happier now.
Now, in all fairness, a lot of people have told me they have had the complete opposite experience, that Linksys isn't worth the silicon its code is printed on, and they'd be willing to run a production site over a D-Link. On the other hand, other people agree with my experience and wouldn't wish a D-Link on their worst enemy (our office uses a Linksys, and we haven't had a lick of trouble with it). Your mileage may vary, I suppose.
