I have had the NSLU2 for almost a year now and it worked fine with an occasional hiccup. Now it started dropping the network connection all of a sudden. When I try pinging it I get replies for a while (say... 15s) and then the connection will go down and after a minute it will come back and then it will go down again and so on... I opened the case and checked how hot the chips get and the only chip that I felt got really hot was the network chip. The Realtek RTL8201cp chip's temperature correlated to the ping packet behavior. I don't have a laser thermometer but from what I can feel with my finger the connections drops when the RTL8201cp chip heats up. I would estimate it heats up to about 50 deg C and then the connection drops... after it cools down again the connection gets restored and I can feel it heat up under my finger under those ping packets. In this thread mrfixit5 reduced the CPU clock from 33 MHz to 30 MHz and that seemed to have helped with his connection problem. But I have a feeling that (at least in my case) the CPU is not overheating and that it is running. Since the NSLU2 always normally responds to the power button press and properly shuts down the NSLU2 using the kernel... the CPU cannot be stuck. So if I am right... the problem should not be in the CPU but somewhere else. Maybe the Realtek chip... I do not have the proper equipment to prove this but if somebody else could check out the Realtek chip on a misbehaving NSLU2 that is dropping the connection... I would love to see a proper temperature measurement or signal analysis on the pins... I will try to run a test by telneting to NSLU2 and running a script that adds a line with a timestamp to a file on the HDD every second. If the CPU really does halt there should be a gap in the timestamps. But the interesting thing is that the connection does come back. Also the switch and the NSLU2 report the connection to be up just the packets (according to the LEDs) are not sent out of the hub to the NSLU2. The thing that bothers me most is that the CPU is actually running at half the clock speed it is rated for. See here... And instead of reducing clock speeds we should be increasing them. Maybe Linksys is using components of questionable quality and is counting on us not to return the units under the warranty. Any thoughts?
