There are several types of router conforming to wireless standards 802.11a g and n.  Your Naim network player will support older 802.11b and 802.11g routers but an 802.11n router will undoubtedly give you better range and network robustness particularly if you plan to stream a lot of higher-resolution content. Our suggestion would be to try your existing router first and only consider replacing it if you find you have problems with poor connectivity or dropouts when streaming media.
