My observation is that it depends on external factors. RS220 use WiFi like 2.4 GHz band sharing alghoritm with neighbouring Wireless Access Points. If there are only few around and well behaved there are no dropouts. In built up areas and when older WAPs are in the vacinity RS220 definitevely...

Generic adapter is fine, the voltage must be exactly the same, polarity correct and ampage either the same or higher. There is a switching power supply inside anyway so unless the generic supply produces high ripple and is poorly grounded there is no way to tell the difference.

I used to have a lot of issues with the wireless signal interruptions on RS-220 and fortunately managed to resolve them over the years. Initially it helped to replace the included rechargeable NiMH batteries with Sanyo Eneloops. I have no sound explanation why it improved the drop outs but it...

I think I am a little bit closer to understanding these mysterious random drop-out issues. My RS-220 stopped having audio signal interruptions after the only ancient ASUS WL-500g WiFi Access point was replaced with a newer Devolo dLAN 200 AV Wireless N.   The improvement is quite...

  Quote:     Indeed that should be the case but for some reason there was a marked improvement with Eneloop batteries. I have checked the included batteries on a computerized tester and their capacity is 870mAh, which is normal as they reach their full potential only after a...

My RS220 were dropping a lot but I found that replacing the included rechargeable batteries with Sanyo Eneloop remedied the situation. They still occasionally drop especially when I am far from the base or close to a WiFi source such as laptop or Squeezebox Controller but nothing...
