Question

Need help with troubleshooting internet problem.

Apr 5, 2016 11:44AM PDT

Hey guys, newbie here, glad i found these forums looking to learn alot about my problem from you guys.

So straight to the topic, i am running a small company with about 8 computers 4 of which are connected to one modem/router and the other 4 to another (cable only no wireless). The setup i am using is having multiple virtual machines on each pc 3-5 and each virtual machine is running under vpn (purevpn is the provider).
This problem started occuring only recently, after having more than 4-5 virtual machines up all with vpn across, say 2 computers, when i try to start more the internet starts slowing down to a crawl, pages become non resposnive and the internet connection becomes pretty much unusable.

I ran some bandwidth programs only to find out that with like 5 virtual machines up the total download traffic does not surpass 1.5-2.5 mb/ps and upload is like about 700-800 b/ps. The package i got installed is 50 mb/ps download and 3 mb/ps upload so it cannot be the traffic generated rather something else. I also talked to the vpn providers techincal support they told me to change to some other dns ports, is this something that can actually help or make a difference ?

The next step i am planning towards is checking the router modem firmware (drivers right ? ) and trying to update them, other thing that could be causing this is the compy that is providing the internet actualyl gave me bad modem/routers ?

I am kinda lost here at start but i am looking to narrow this problem down for sure, and with your help i am more than confident i willget to the bottom of this. Any tip or advise you can give me is more than wellcoming i am getting kinda desperate here lol Grin

Clarification Request
Maybe a router conflict?
Apr 6, 2016 10:16PM PDT

Some questions for clarification..
1. You said two modems/routers. Do you mean you have two modems and two routers, two all in one's, or just two routers but not sure what the difference between the two are? (It's ok if you don't, I didn't either.)
2. Are both in the same building? If you have two Internet providers, then two modems makes sense in one building. Unless your talking about different buildings here..

If what I'm thinking your talking about is the case and you have two routers on one isp then I think you may be experiencing some router conflict and I would try hooking all of your computers to a switch, and plugging the switch into only one router. From there, router plugs to one modem. Or you could configure your second router as your switch and do the same.

Sorry

But did I read this right? You got advice about a DNS change and didn't take it?

Anyhow, I have been using other DNS's for years. I used DNSBENCH to pick which one gave me better results.
