I am having a problem with the wireless in our office, I sit in a different office to the Access Point so there is one wall between me and the device. The signal I get is Very Good.
However, there are users in a open plan office about 20m from the access point and they get a low signal at best; generally they can't connect at all. I can only assume there is something causing interference in that area. I have looked and we have a light sensor and an alarm sensor in that area. There is also an old, wall mounted wireless AP but it is powered off (don't know what it was used for as was before my time).
Can anyone suggest what might be causing the issue or any way I can test for interference?
Thanks for your help.
