I have recorded all my CDs on my IPad and want to buy the new AD7000W to play all my music in future. My worry is that I might have connectivity problems with my wifi router. The Talktalk N speed router is located in my study upstairs with a pc connected by cable. My IPad is wireless of course and I have not experienced any connectivity problems as yet. I only intend to use the speaker downstairs in the lounge and I am hesitating to go ahead because no retailer can reassure me on this subject. Has anyone got a similar arrangement ?
