Internet disconnect under heavy load.

by JonathanXO / April 14, 2016 11:28 AM PDT

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 ?

modem: technicolor tc7200.20
router: cisco linksys e12000

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.

Keep testing

Hey Jon,

I like what your doing and your traffic stats sound correct.

Test layer 1

I would run some tests on your network to clear errors. Run the resource monitor on your task manager and compare that to your speed test. Check for circuit drops when NOT running your VM's. You may be dropping packets or service randomly. You can also run this command in your CMD:

ping -t

If you come back in 24 hours and see packet loss, your service is dropping then I would say it's not traffic related.

If you have multiple devices you can test to see if it's just your PC that's dropping. Does everything stay connected? Can you check your router logs for dropped service? What errors are you seeing?

If there are errors or drops not related to your high load, call the service provider to run some tests. It could be a bad modem, Demarc, water in a man hole or on a F2 cable pair, bad Pots line, high SNR ratio, long loop length blah blah blah.

Also, ask what happens if you exceed your up/down limitations. Are you charged? Are packets dropped?

TCP/IP retransmits so if the ISP is dropping the data due to load, then your connection can appear to drop as your servers fall off while your circuit buffers.

You can also replace all of your internal wiring up to the modem.

Our goal here is to ensure that you have 100% Uptime with no errors. Once this is cleared, then we can test layer 2.

Let me know how that goes.

weather its true or not I have read that with the wifi adaptors [???] that heat up under a lot of load and can cause this ?? mine can get kinda warm when heavy useage but only seems to disconnect when idle/no activity for a time .

wifi is no where near anything close to hardwire and seems to work as it feels like for anytime of the day

AP heat issue

I have my doubts but anything is possible. My company uses Cisco 2202's and 2702's in the field at US airports. Phoenix has external temps in excess of 110*. I am sure there is a difference in quality however.
