Windows 10: Network gremlin - intermittent request time outs in ping sequences and periodic internet...

Hi folks,


I have a farm, and we use a bunch of computers, funnily enough. We've been having an internet problem for the last few months where things will be fine for a while.


Then the internet will get really spotty, going out for short and long chunks of time and then while it is back it is weak and pings take a really long time to reach out - we get half more or less of the requests back pinging mit.edu.


About a month ago we tested things by removing computer by computer from the network. Eventually we found one computer that after turning it off, the problem cleared. So we removed it from the network.


Things cleared up for a while weeks.


Then yesterday, same problem comes back. Last night I removed one by one each computer from the network and tested pings. We found another computer that after turning it off, the problem cleared up.


But the problem is back today. Intermittently.


Malware? Something else?


We run Vipre Antivirus.

Operating system Windows 10 Pro on all computers, except the server is Windows Server 2012.

Ethernet network - wired

Cisco router RV220W

Comcast router Technicolor Device Type:BWG, Model: DPC3941B - which we had tested by Comcast earlier on. Set up a as a pass through.



What else can we check or test?


Any help or suggestions very welcome!


Thanks,

Sarah

Getting "Request timed out" when doing a ping on a server.

I am trying to connect to a server on the internet. Other pc's on the network can connect to it but I get "Request timed out" when I try to ping the machine. Here is the screen shot:

C:\Users\Owner>ping svn.zeropoint.com

Pinging svn.zeropoint.com [63.78.117.80] with 32 bytes of data:

Request timed out.

Request timed out.

Request timed out.

Request timed out.

Ping statistics for 63.78.117.80:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

I had my ISP technician try to ping the server and he was successful. I am able to connect to every other server that I try to connect to.

 

Ping error: Request time out

Hi,

I have a big problem:

I am using Windows 10 Home with Kaspersky Total Security. I VMware and running some virtual machines on it (Windows 7 and Windows 10 ENT).

I made a loopback network adapter on my Windows 10 Home. Here are the network configurations:

Windows Home WiFi adapter:

IP and DNS: Auto (192.168.1.X)

Loopback adapter:

IP: 192.168.11.1

Subnet: 255.255.255.0

Gateway and DNS: empty

==============================

VMware (network adapters are bridged):

My virtual Windows 7:

IP: 192.168.11.2

Subnet: 255.255.255.0

Gateway and DNS: empty

My virtual Windows 10 ENT:

IP: 192.168.11.3

Subnet: 255.255.255.0

Gateway and DNS: emty

==============================

The problem is the both VMs can ping each other (after allowing firewall to ping)

But my main Windows 10 Home cant ping the VM machines, also they cant ping my Windows Home too. When I ping VM machines from my main Windows I get this error:

C:\Users\amin>ping 192.168.11.3

Pinging 192.168.11.3 with 32 bytes of data:

Request timed out.

Request timed out.

and when I ping my main Windows from VM machines I get:

C:\Users\amin>ping 192.168.11.1

Pinging 192.168.11.1 with 32 bytes of data:

Reply from 192.168.11.3: Destination host unreachable.

What did I do:

Configured Windows firewall to accept (in/out) ping by enabling File and Printer Sharing (Echo Request - ICMPv4-In) but no luck.

 

ping on switch request time out

I have connected 2 pc with windows 10 on switch. I gave static ip address in ipv4 as 192.168.1.104 and 192.168.1.103 with subnet as 255.255.255.0 and default gateway as 192.168.1.1. I enabled the inbound rules of file transfer in firewall also. I tried
to ping from one pc to another but it is showing request time out. Also the network folder is showing all pc file on network.
