Hi,
What's your device model?
try reducing the power and check the alignment. Otherwise try another channels
The are too many things to consider in a wireless link, yo you need to be patient.
Did you ever work it out? My SXTsq Lite2 PTp usinv NV2 drops out within 30 seconds.
I am in the process of checking for silly things and getting some configs. I only get 10 seconds to login, export and down load the config files. Its about 400km from me at the moment.
