I have a problem with WiFi phone SMT W5100 that when it goes out of range and come back it doesn't connect automatically - have to restart phone or manualy choose system. There is OS500 and SMT R2000 Access point. Phone SW version is 1.6.4. I have tested a phone with same version on R2000 and OS7200 and it works fine - gets signal as soon as it gets back in range. Different PBX shouldn't be the reason for problem... Any ideas?
