I am not sure anyone experienced this before, but whenever I am connected to the Internet, immediately my PC will show the IP conflict error, it only happened when I am connected to the Internet only, and my PC is connected directly to the modem (point-to-point), I already check all the IP setting within the modem, so it is not possible to get an IP conflict error and there is no other device on the LAN except the modem and PC, but then when I try to change the IP range of the modem into a much more higher range which is by default starting from 192.168.1.1, later I found out that the problem disappeared.
Beside this I found out that whenever I am connected to the Internet, a browse to my modem web interface show me other brand of modem instead of mine, I can only access to my own modem when I disconnect the modem from the Internet, the modem supplied to me by streamyx is Riger but instead I saw Aztech, Billion and others which is clearly not my modem, but after when I changed the IP range as above only I can access to my modem web interface without any problem.
So it appear to me that, whenever I connect to this 4 Mbps line, I was like connected to a bigger LAN together with other 4 Mbps subscribers in my area, and this might be the reason why my Internet connection get disconnected very often, amazing isn't it but this is just my assumption only!

I had this problem before, ip conflict right after upgraded from 1 mb. thought was my network problem, then, I changed my modem to ip 192.168.0.1, no more conflict. Few days ago, my trouble line fixed (frequent disconnected 5-60min), tried on router now 192.168.1.1, no more of that ip conflict.
I think you should report to them(tmnut) having this disconnection problem. Shoot them 10-20 times, until the so-called special 4mb team move their a**. Keep the report #, tell them definitely will reimburse all costs from days of frequent disconnection, then cancel if not fixed.
