We never found a "booster" or "extender" that didn't cause problems.
The symptoms described by the OP are consistent with the SoundBridge momentarily losing connectivity to the Wi-Fi network. The fact that moving it close to the access point makes the problem go away supports this hypothesis.
So, the options are to relocate the networking equipment so that the SoundBridge gets a good (direct) signal at the desired location, replace the access point with something with more range, run Ethernet to the SoundBridge, or use a Wi-Fi to Ethernet bridge so that the SoundBridge only sees an Ethernet connection, not Wi-Fi.
very pleased to hear from you and to know you are still around, even if it isn't the best of news.
Unfortunately I am unable to relocate my wireless router or run ethernet cable, due to the circumstances of the building. I will investigate the 'something with more range' option.
Also are you saying that if I use my Belkin signal booster as an ethernet bridge it won't suffer the same problem?
You say that it is likely to be a momentarily loss of signal from the booster to the soundbridge, I am interested if this is consistant with the fixed time periods (on careful monitoring it does seem to be very consistant at losing the signal after 1hr 10m) and if you have any suggestions on what causes that interuption, ie is likely to be something related to the booster, or something happening externally to temporarily block the signal, etc.
Finally, I am confused on why the Soundbridge, having lost the signal momentarily, would then be locked out and need restarting, rather than just being able to reconnect (either automatically or manually), but not effect the internet radio connection.
I hope you are able to respond or point me to something that can help me understand and hopefully resolve the problem.
Officially Roku don't recommend access points/boosters as the 'double hop' can make things more complicated. That said, I run a belkin modem/router on one floor the house, with my SB next to a belkin AP downstairs and it works fine. When I first set all this up I spent a fair bt of time on the phone to Belkin support to get things figured out,
Depending on your model of router/AP have a look at this post and my instructions therein. May be of help to you...http://forums.rokulabs.com/viewtopic.php?t=13600&start=0&postdays=0&postorder=asc&highlight=frame+bursting
thanks for your comment, I did look into this, but wasn't able to apply any of it. I don't have a Belkin Router, I have a BT Broadband Hub, with a Belkin booster, non of the settings in the Hub seemed to reflect your Belkin settings, but if you have any other thoughts I would be please to hear them.
