Gone to crud? I'm not sure any of their other equipment ever worked. All the 802.11/g/n Wireless routers and PCI, USB, and PCMCIA adapters I have come across were rubbish. Most recently their KVM enraged me to the point where I was ready to yank it out of my cubicle and throw it down the hall.
I took a 10 min break and went to the next door cafe to calm myself. When I came back, I inadvertently found me a Blackbox KVM...so much better. These two years, I thought my NEC LCD from 2003 just sucked. It turns out it was the horrible image quality from the Dlink KVM switch. I though the ghosting was a result of the 25ms LCD...now I know to blame the Dlink KVM.
Why it frustrated me? About 50% of the time switching a channel doesn't work properly. Either the whole thing locks up and does not respond to keyboard or mouse input, or the keyboard works, but the mouse does not (though never the other way around). USB mouse that come with PS/2 adapters never work so I've been stuck with a ball mouse for a while. When it locks up, the only solution is to keep switching channels until it works correctly. On that day, it happened to be more like 95% of the time I had to switch channels it did not work right. Imagine you have to switch channels 20+ times before it functions properly...
I once attempted to get it fixed under warranty, but they said I had to send it in first and that it will be at least 4 weeks until I hear back from them about their decision.
