My hi-fi setup is a DacMagic DAC fed from the USB port of my Dell laptop; output to hi-fi preamp. The Dell Inspiron 1545 has only 2.4GHz wifi. My phone, Galaxy S2, and tablet, Galaxy Tab 2 10.1, have both 2.4 and 5GHz wifi. The room I have the hi-fi in is covered by a Netgear WG603 V3 WAP; the BT HomeHub 4, near the master socket, does not give a very good signal in this room - oldish house with thick walls. The laptop and the phone/tablet talk to each other via this WAP. The problem is that Playa Control for Winamp loads the library very slowly. I only use the albums function on Winamp; I do not create playlists as these would only be the same as the album listing. I think the bottleneck is mainly the WAP at 2.4GHz. I have a 5GHz USB dongle that I could fit in the laptop. Would I get much improvement in Playa Control if the devices talked at 5Ghz instead of 2.4GHz? If so can anyone recommend a replacement WAP for my Netgear unit?
