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.

What are the Virtual Machines doing?

It's entirely possible for something "heavy" like downloading a bunch of torrents to overwhelm a low-end router. Your overall bandwidth wouldn't reflect that, but you'd see heavy CPU/RAM use on the router itself.

how do i check cpu/ram use on router ? we are not downloading torrents rather botting in a game league of legends.

 

[dave_the_nerd]

How to check those stats depends on the router. You'll just need to read the manual.

You might want to implement QoS and per-client bandwidth limitations on the routerside too, if maybe one system is somehow "hogging" the bandwidth.

But you've got, effectively, 30-something PCs running off of a single network connection. You're probably beating your router up pretty bad keeping track of all that traffic.

PureVPN allows users to utilize single account on up to 5 devices simultaneously from the same country.

You might be getting throttled by PureVPN. Each VM counts as a separate device.

Lulz if you are botting or selling bots for League of Legends, pay someone to comein and fix your network woes.

btw is this model any good ?

modem: technicolor tc7200.20

Could it be the router not supporting multiple computers ? since one pc with 4 vm counts as like 5 computers ?

That modem should be able to handle all those connections and then some.

Test your connection with the same setup, but no VPN. I still think PureVPN is throttling you.

You could even try the same setup all with VPN, then test your connection from another PC or VM without VPN. If that speed test is fine then it is your VPN.
