Hi all 
It seems that I'm cursed... every time I fix a thing, something else stop working, so there must be always something wrong in my system
When I had the old router, a D-Link 655, everything worked perfectly until the router decided to give up and started to get random disconnections, so I purchased a new router, the TP-Link TL-R600VPN.
The router itself seems good, but I still got random disconnections, so I also changed the modem, installing a TP-Link TD-8616 (the old modem was a Linksys AM200).
So far so good, I get no more disconnections, but now I have another problem. One of the software I was using regularly with the old modem/router configuration now crashes randomly.
The software is Internet Download Manager (IDM for short). I already asked tech support to fix the problem, but they seems able only to blame any security software that can be installed in computer.
Before this problem started, I changed nothing in my operative system, I changed no configuration, I installed nothing, and IDM was working perfectly.
The only thing that actually changed is the modem/router. It seems that there is something that causes IDM to crash.
The only answer I got from tech support was the following:
So, according to them the only solution is to disable or even uninstall any security software in the computer... That's simply insane, a software that can run only without a firewall is completely useless.
Moreover, if the firewall really causes conflicts, why IDM doesn't crash immediately but only after a random amount of time? Sometimes it crashes after few minutes, sometimes after few hours. Both windows firewall and router firewall are running when I start IDM, so if what they say is true, these "application that tries to control all traffic and disc activity" are already there and should intervene immediately after I run IDM.
However, before to say goodbye to money I paid for this software, I'd like to make some tests. Of course, I want to keep the firewall running, but I wonder if there is some way to configure it to avoid conflicts with IDM.
As I already said, there is nothing different in that computer except for the modem/router, so I think that installed software can be excluded as cause. Is it possible that is indeed one of the already installed software to be incompatible with the router? There is anything I should check or configure better?
Some more information if needed:
operative system --> Windows Server 2008 standard
firewall --> the default firewall included in win server, I installed nothing
other software installed --> nothing! in that machine there is only operative system, mainboard drivers, and IDM, nothing else.
Anyone have suggestions? If it can be useful, the user manual is freely available here
I checked settings many time, but the web interface is quite simple, and I can't change many parameters. I have no idea what to check or what parameters must be changed. Any help is welcome.
Thanks in advance

If IDM uses a lot of CPU it means that there is a conflict with some other application that tries to control all traffic and disc activity.
