If it is not possible to move the wireless router to a central location your best bet is to try and add a wireless extender, preferably a hardwired one.
If you are using a router provided by your ISP, or it is more than three years old then the purchase of a new model may improve wireless coverage throughout your home. This will benefit not only wireless audio products, but also your other WiFi connected products.
