If you own a pair of wireless speakers and are having problems then read this tutorial. Even though I am not going to be able to talk about a specific model of speakers, I will give some general advice which you can use to troubleshoot 90% of problems.
First of all, when purchasing wireless speakers I always recommend to purchase a model that avoids frequencies that are used by other wireless devices in your home. You may be using a wireless network. Nowadays most wireless networks transmit the signal either at 2.4 GHz or 5.8 GHz. First of all, figure out which frequency band your router uses. You can do so by going into the router menu and then to the wireless section. There you will find which frequency band is active.
If both frequency bands are being utilized then I suggest disabling one band. If you are disabling the 2.4 GHz band you can go ahead and purchase some speakers that work at 2.4 GHz. Obviously there will be no conflict between the router and the speakers. However, before doing so try out the wireless Internet connection first. If it turns out that the 5.8 GHz spend does not give you sufficient wireless range then you might instead want to disable the 5 GHz band. In that case you can go in and purchase some speakers to work at 5 GHz.
However, more modern types of speakers are able to coexist with other wireless transmitters. These types of wireless speakers have intelligent channel switching techniques. Some other models allow you to set the frequency channel manually so you can avoid channels being used by your router.
Another common problem for wireless speakers is the power supply. Verify that the power supply delivers a stable voltage. Also, the voltage should match the number which is written on the power supply label. Many wireless speakers will also have to voltage written at a location near the power connector.
