Internet disconnect under heavy load.

[JonathanXO]

Guys i am really depserate, this problem started happening since like a few weeks back, whenever i am under heavy internet load (botting in league of legends) internets disconnects.
I have around 4-5 virtual machines on one pc and each virtual machines has 5 league of legelds client on, so basically 20-25 clients per pc, i cannot run more than one pc on same network. Funny thing is about a month ago all was fine, so problems started happening just a few weeks back.

How do you troubleshoot this kind of problem ? And how do i know it is not the router modem, rather the isp company and problem with the signal from the cables that come to my modem ?

I now have two seperate internet connections, one with 15mbps dl and 1 up, another with 50/3. Whats even stranger is that the 15/1 can handle 5 virtual machines whereas the 50/3 can only handle 3 at best, i know it is not download upload limit coz 1 vm drains about 220-250 kb/ps so about 1mbps traffic from 1 pc.

modem: technicolor tc7200.20
router: cisco linksys e12000

Try downloading a torrent file that has a lot of seeds. Note down the peak download speed. Then leave it for a sustained amount of time. If it does not disconnect abruptly, then your ISP has nothing to do with the problem, in my opinion.

Are you completely saturating your connection during this time? What is the DHCP lease time like? I have actually seen situations where ISP sets that very low, and if the connection happens to be saturated for extended time the renew packets may not make it through and the IP is eventually lost, and the connection dies, then by the time the renew happens you get a different IP.

Totally random, but worth checking to see if it's that.
