I've been running a Linux-based router for a few years with no problems under 5.5. I got a new server, installed ESXI 6 U2 on a USB Flash drive, and copied the VM over. I configured the network adapters (As E1000), and started up the VM. The Router works, but seems to be dropping packets. Going to webpages will often hang for a long time. Running continuous pings to external websites shows random timeouts at least every minute, sometimes every 10 seconds. Any idea what might be causing this, and how to fix it?
Can you please let us know, what is your Linux distribution?
Also send us your ESXi build number.
I'm running the Dell rebranded version 6.0 U2 3620759, and the distribution is Sophos UTM 9.3. I believe it has vmware tools built in. Thanks!
let us know the out put for below commands
esxcli network nic list
esxcli network nic get -n vmnic<0>
vmkchdev -l | grep vmnic
Thanks & Regards
I'm running it on a Dell Poweredge R610, using the internal 4 network adapters. One is unused, one is connected to the LAN to manage ESXi, and the last two are the LAN and WAN adapters for the Sophos UTM VM. The LAN and WAN are currently unplugged.
esxcli network nic list returns:

Driver seems to be latest, update the Firmware. Is it possible to use vmxnet3 adapter and test the packet drops.

Process to update the drivers:
To install the async drivers (http://kb.vmware.com/kb/2005205):
|1.||Download the zip file from the link provided in my previous email.|
|2.||Extract the contents of the async driver zip file.|
|3.||Identify the offline-bundle.zip file(s).|
|4.||Log into the ESXi host using the vSphere Client with administrator privileges, such as root.|
|5.||Using the Datastore Browser, upload the offline-bundle.zip file(s) to an ESXi host's datastore.|
|6.||Enter the host into maintenance mode.|
|7.||Log in as root to the ESXi console through SSH (PUTTY) or iLO/DRAC.|
|8.||Run this command to install drivers using the offline bundle (this requires an absolute path):|
|9.||For latest Firmware please contact Hardware vendor.|
esxcli software vib install -d /vmfs/volumes/<path of zip file location>/name.zip (if this does not work then try the below localcli command).
localcli software vib install -d /vmfs/volumes/<path of zip file location>/name.zip
