On the off chance that someone here uses homeplugs and maybe at least heard about related problems... also, my warranty is void in two weeks, a more or less quick answer would be very much appreciated... So I bought these almost a year ago, plugged them in, and they were on constantly until this August, when I went on vacation for a month and a half. I get back home, plug them in, and one of them starts making a hissing sound. It's no joke, either - you can hear it outside of my room. The sound starts only when the LAN is connected and working, though, the hissing is very faint when just plugged in. So, I went to the shop and told them my problem. They shrugged, and sent them to a service centre. Guess what, they came back from the service centre with a reply "no defects found; test and software update performed". I come back, plug them in, and the one that hissed before still hisses like a very annoyed average cobra (actually, as loud as the PC). It doesn't seem to get hotter than usual, and there are no error lights or anything. Just the hissing. Any clues? Previously encountered similar problems? Anything? Thing is, I could just use the wireless key for this desktop, but my wireless key doesn't seem to like 64-bit Windows 7. It works... passably well, but the signal's weak and sometimes drops out.
Did you try a different power outlet? Is there any other devices plugged into the adjacent outlet? Personally I don't like these type of networking adapters. I know how little it takes to drop information here and there, power cabling in a house is not as reliable as dedicated network cabling.
Yes, I did try them, of course. And other devices are plugged in, but it's never been an issue before (and I don't really have any choice, with the sockets being what they are). Bah, I would've liked to just stretch a cable myself, but now it would look ugly. Nowhere to hide it.
Hmm, well hopefully someone can chime in with some answers. The only other thing I can think of, if it's not interference, is the one device is on its way out.
Go to the shop and tell them to plug it in then and there and see what happens. If you can show them what's going on that proves a faulty product. Alternatively, you could video it and e-mail/burn a CD with the video on to them.
The only problem with that is, the technician needs to recreate the problem in the lab. If that can't be done, then there isn't an issue, at least from the technician's perspective.
They're not Comtrend Powerline adapters are they? I had a set of those for about two and a half years until one of them had a similar problem (more a light buzzing noise than hissing on mine though), it eventually blew and fried the router that was plugged into the plug socket it had built-in. If the technician can't re-create it in their lab, it might be worth checking if they can do a call-out for a small fee to witness the issue in your place (though if the fee is anywhere near as much as you paid for the device then it isn't worth it).
No, they're Siemens, but yes, the fee in this country would probably be twice as high for calling a technician... there's no hazard (except if it destroys a socket...); they don't plug anything in at the shop, they send it elsewhere; so I guess I'll stick with them for now. Will post pictures of melted plastic, if anything happens (well, hopefully not). Thanks for your time anyway.
Hello. I've used home plugs since 2006, the same set and they work very well. I have the Devolo dLAN type and can say that I have never had a problem. They're expensive but worth it. I would bin the ones you have and save yourself grief with repairs or not and buy a pair of Devolo's.
i havent had this problem with mine. mine are generic ones off ebuyer called Value. I would probably say its better to buy a new pair.
