Wireless noise interference

mileycactus

Really strange issue I'm having since yesterday. I have a sharp surround sound system that started making a loud buzzing sound almost so loud you can't hear the tv. I spent ages trying to find out what's going on and the only way to get rid of the noise is when I plug out my UPC Cisco wireless router. Sound goes away instantly! Tried changing the wireless channel to no avail and to top it off I have noticed the plug for the router is very hot. During a router reset the sound remains.. As is said.. Strange..

Anyone any ideas?

Its the PSU not the router, its creating interference on the ground loop. You should separately ground the sound system(there should be a mount) to a radiator or something.


Also, if its that loud you probably have a bad set up in that an amp or preamp somewhere is working very hard.

Thanks ED E, but what's the PSU? By ground separately do you mean a different socket? Can't find any mount

It may not be the power supply, I have this problem with my router too, move them apart and you'll be fine, a meter should be ok.

PSU is the power supply unit. The power brick usually.
I had a similar issue with a powerline adapter causing audio issues.

By earthing the sound system he means connecting the earth pin of the system to the radiator directly instead of to the earth in a socket.
