You can try changing the server expire time to shorter one like 360 under web interface-> account-> Register.

Thanks for your response

I initially reduced the Subscribe Period to 240secs, but the disconnection occurred again five days later. I then tried 120 secs, but this morning, disconnection again.

I thought that this was a useful parameter, but apparently not in our present context - what is the difference with the Server Expire setting ?
I will follow your advice and try to reduce the Server Expire parameter

There is no such setting on the W52P, should I use Login Expire instead ?
