Hello,
Brand new admin of a small IT network (about 17 users) that go through a corporate VPN. Our little slice of the world has some pretty bad latency issues since I've been here. They said it didn't used to be that, not sure what happened but the network just became slow. It's hard to stream a video which isn't something we frequently do. We cannot watch a live VTC even if we all try to do it from one workstation meaning no one else should be using bandwidth. Our printer VPNs as well and it is painfully slow to connect to or print from or even try changing print settings and properties. I read somewhere taht MTU is the most common problem and to run:
ping -l 1500 internal-ip
ie ping -l 1500 ***.***.**.**
(subsitute the numbers obviously) from my destop to another desktop on the same network as well as to my gateway, and it didn't work BUT I can't ping any internal IPs from my desktop so I'm guessing that's becasue we are all VPNd? I'm trying to ping via their local NIC not the VPN NIC. I have no idea how that all works. Maybe there is a rule blocking internal pinging who knows. So next I ran a:
netsh interface ipv4 show subinterface
and received
4294967295 1(Byte in) 0(bytes out) 253031 Loopback Pseudo-Interface 1
1500 5 (mediaSenseState) 0(Bytes In) 0(Bytes Out) Local Area Connection
1500 1 (mediaSenseState) 193464316 (Bytes In) 123710361 Local Area Connection 2 (the local NIC I tried to ping)
1400 1 (MediaSenseState) 149954102 (Bytes In) 90166045 Local Area Connection* 9 (the VPN link)
Please help I don't know what this means or if I'm even doing it right!!!!
