Can no longer connect my B&W A7

Hello :

Recently bought Airpot Extreme and my A7 will no longer connect via AirPlay. Do not know what to do B&W tech support wrote me this:

If you are able to set up your A7 but, it will not work wirelessly network can you please try to make the following changes.

1. Change your wireless network radio mode to ‘802.11 g only’.

2. If still having issues, change the radio mode to a non-overlapping channel. Try either channel 1, 6, or 11.

3. If you are using a dual band router, make sure the 5Ghz and the 2.4Ghz network does not have the same name (SSID).

I hope that this helps resolve the problem you are having. If however you are still encountering problems or have any further questions at all, then please do not hesitate to contact me and I'll be happy to help.

With kind regards
