Well here at my work (a motel) the front desk people often have to walk out to housekeeping or even just do a walkaround of the building. We have a cordless phone for this purpose. Now the old 2.4 Ghz phone was a piece of garbage as soon as I get maybe 5 doors down, it stops working. It would still ring if I had a call, but if I tried to answer it, there would be nobody there

Anyways, we assumed this was a problem with the phone so I come in to work today and my boss had purchased a brand new phone. 5.8 Ghz, crazy display, VERY nice phone. Range still sucks. Except the new phone won't even ring. I used to have 900 Mhz phones back in the day that had way more range than these things. Therefor we assume the building may have something to do with it? Anyways, my question is, what sort of things could be hurting our range, and is there anything we can do to improve it?
