Teamviewer freezes after some time (randomly)

[Mario]

Issue with FREE versions 9 and 10 (installed/portable).

NOTE: It is happening for all machines in my local network (but connection establishes for machine not in my network). So, I suspect that it is something with my network/internet provider.

Description:
1. Connection establishes fine and with good quality.
2. After some (RANDOM) period of time screen just freezes (not moving at all) and I need to reconnect.

Findings:
1. It is happening for both incoming and outcoming connections.
2. Usually after each next reconnection it freezes faster (Ex. 15 minutes -> 2 minutes -> less then minute to next freeze).

Not even sure where to start for troubleshooting.
Can anyone help ?

could be something like http://www.netlimiter.com/ or http://bandwidthcontroller.com/index.html or some edge device in your network.

These type of things will slow unknown connections to a crawl.
This is one to combat illegal downloads on a corporate network for instance.

Check with your network admin at that location

there are some software mentioned at the bottom that can test for this

Matt, thanks for your reply.

Actually, as I know, my internal internet provider using some traffic shaping tool.
The reason is about cost of internet (to decrease speed for cheaper plans).
But, speed is fast - up to 40 Mbits.

Can this be a reason for my issue even with so big speed of internet ?

Yep
