Q. I have never had any problems with this subwoofer before. I recently moved houses and setup my system there. Everything seemed to be working beautifully until I woke up in the middle of the night to horrible feedback coming from the subwoofer. I immediately turned the power off and it stopped. So, I tried to switch the subwoofer to "Auto" mode which kind of puts the speaker in a sleep mode until it is being used. This also did not solve the problem. When music is played on subwoofer, it sounds great, but once it ends, after a while, a feedback "beat" is heard and repeated over and over. Any suggestions? This wasn't happening before the move.
A. Hmmm, it could be many things... I have a JBL speaker system with a powered sub and I had a similar type of feedback humm, but I discovered it had to do with the auto sleep mode. Oddly enough (like you) this only happened to me after moving into a new home, go figure! So aside from some trial and error with the power save feature of the subwoofer, it's time to dig deeper.
Do you get normal results when you run a test-tone test, if your head unit has this feature? First, if you don't own a second one, see if you can borrow another subwoofer and swap it out temporarily. Try to rule out an issue with the speaker itself, if another sub does the same, you have an issue with your head unit or cabling or power. Are you using a halfway decent power distribution system or power strip, like a monster power strip with good noise filtering? In the new house, where you set up your system, are there any sources of interference nearby like from utilities or appliances or computers? Are you using a good quality cable to conect the sub to the head unit? I realize it worked fine before, but it could be a cabling issue if there's an external electromagnetic interference problem near the new home that didn't exist at the old home, like from nearby communications equipment, alarm systems, wireless networks, cordless phones, baby monitors, wireless CCTV systems, etc.
Or it could be dirty power for these same types of reasons, so be sure to use a good power strip/filter. Expect to spend a few hundred dollars on a good one. Myself, I use the Monster Power HTS 3600. And make sure the outlets where you have everything plugged in is properly grounded. Use a tester or have someone who knows home electrical confirm it for you. Ideally, this will also be a dedicated 15 or 20 amp outlet with nothing else on it like lighting, etc.

How do I fix the buzz on my PS3?
Q. Ever since I got my PS3 in November of last year, it's had a light buzz that annoys the crap out of me. I've put it on three different TVs, and they all share the buzz problem, as well as lines scrolling through the picture. My question is, simply: How do I get my sound and picture working normally?
A. I had this issue as well. It seems to be interference by another electrical device. In my case it was the baby monitor. I found a new plug for that. Does your PS3 share a power outlet with something else? If so, try putting your PS3 on a power bar, or its own outlet.
How do I improve a routour range and speed and it has no attena?
Q. It's a at&t model 2wire
A. Try placing the router in a higher central location, avoid physical obstructions whenever possible, also avoid reflective surfaces whenever possible. Some Wi-Fi signals literally bounce off of windows, mirrors, metal file cabinets and stainless steel countertops, lessening both network range and performance.
Install the router at least 3 feet away from other home appliances such microwave ovens, cordless telephones, baby monitors, and home automation equipment like X-10 devices.
Likewise, install the unit away from other electrical equipment that also generates interference, such as electric fans, motors, and flourescent lighting.

Is there anyway to boost my reception in my basement?
Q. I get decent signal on the main floor and when i go in the basement my signal sucks. I have Verizon
A. Well here is some information that tells you what interferes with wireless signal:
Sources of interference for wireless devices and networks
The farther away the interference source, the less likely it is to cause an issue. The following items can cause interference with wireless communication:
* Microwave ovens: Placing your computer, Bluetooth wireless device, or AirPort base station near a microwave oven that is in use may cause interference.
* Direct Satellite Service (DSS) RF leakage: The coax cable that comes with certain types of satellite dishes may cause interference. Obtain newer cables if you suspect RF leakage.
* Certain electrical devices such as power lines, electrical railroad tracks, and power stations.
* 2.4 GHz or 5 GHz phones: A cordless telephone that operates in this range may cause interference with wireless devices or networks when used.
* Metal objects: If possible, move metal objects or change the placement of the computer, wireless device or wireless access point so the path between your computer and the wireless device or wireless access point is free from metal objects that may cause interference.
* Video senders (transmitters/receivers) that operate in the 2.4 GHz or 5 GHz bandwidth.
* Wireless speakers that operate in the 2.4 GHz or 5 GHz bandwidth.
* Certain external monitors and LCD displays: Certain displays may emit harmonic interference, especially in the 2.4GHz bandwidth between channels 11 and 14. This interference may be at its worst if you have a portable computer with the lid closed and an external monitor connected to it. Try changing your access point to use 5 Ghz or a lower 2.4 GHz channel.
* Any other "wireless" devices that operate in the 2.4 GHz or 5 GHz bandwidth (microwaves, cameras, baby monitors, and so on).
Note: Some devices may not overtly state that they operate in the 2.4 GHz or 5 GHz bandwidth. The operations manual should indicate the frequencies the device uses to operate. These may be referred to as "Dual Band" or "Wireless" devices.
Effect of home and office elements on wireless communication
Where you are located and what materials you are surrounded by can affect your wireless networking performance or Bluetooth wireless device. The table below shows common elements and their potential for interference.
Type of Barrier Interference Potential
Wood Low Interference
Plaster Low Interference
Synthetic material Low Interference
Glass Low Interference
Water Medium Interference
Bricks Medium Interference
Marble Medium Interference
Paper rolls High Interference
Concrete High Interference
Bulletproof glass High Interference
Metal Very high Interference
I would say your problem is Concrete because of the bricks, which are almost the hardest next to metal and bulletproof glass... But if you can get a wireless access point and get it at the entrance of the basement, it will take the signal from your router and extend it into your basement. You can take these WAPoints and move them around to see where you get the best signal in your basement with where the access point extends the signal too. I hope this helps. Also some of the other items listed above can cause inteference but I would suspect the concrete and start there. There not too expensive and you can have more than one.
