I have a customer with a Linksys router that wanted to get access to the internet from a few home networked devices (Samsung Blu-ray player in one room, Dish network DVR in another room), as well as continuing to get Internet from his wired computer. The DSL modem is hooked up correctly to the Linksys router, and the router is connected directly to the computer. I added a second Cat5e (and tested the run using a Cat5 tester) from the router back to a DGS-1005, which I placed in the structured wiring can. I tested the Cat5e going from the can to each of the rooms, and everything tested well. So I hooked each of those into the switch.
Easy install, one would think. And I was able to get Pandora and Netflix on the Samsung BDP, and I was able to network control the DVR. But as soon as I would play something on one of these devices, the customer was UNABLE to get internet access on the computer. If I unplugged the Cat5e from the router to the computer and then plugged it back in, everything would work again for a little while, and then would stop working again.
After testing ALL of the cabling again and replacing some of the cabling "just in case", I finally replaced the DGS-1005 with a DGS-2208. Now everything works. So I must have gotten a bad switch, right? So I took another DGS-1005 (brand new in box), dropped it in instead of the DGS-2208, and the new switch behaves just like the original DGS-1005.
So there's something different in the DGS-1005 from the older versions of the same switch. Please help me figure this out. I've always used D-Link switches because they are highly reliable at a good price. But obviously this scenario isn't working, and I can't afford to make 3 or 4 calls for one measly switch replacement...
