Indeed, there's a typo in the spec sheet.  Page 9 says it's a 10/10 (aka 10Mbps full duplex) interface.  In fact, it's a 100 Mbps interface because that's what the switch (and wireshark) show it as.

BTW, this issue of LAN speed is the least of my concerns in the overall picture here...

J-R:
10/100 is still common, typically for low-power, "simple" devices.  1G devices that use wake-on-LAN will negotiate to 100M when asleep.

Packet loss when using DHCP is a classic result of having two devices with the same IP, although not always.  There are various ways to test this such as checking your ARP table, but my suggestion would be to go ahead and set up a DHCP reservation for that MAC address.  Then you can switch from static IP to DHCP as you wish without another device getting the same IP.  Pick a guaranteed known-free IP when creating the reservation.

It is remotely possible there is a fault in the network stack involving the DHCP process where it is misbehaving.  Once you have received an IP from the DHCP server, there is still traffic that continues in the background every so often, such as for renewing the lease before it expires.  Seems like a stretch, though.

Folks,

Be apprised that I deleted my post that had an image of my system information.  -Probably not a good idea to post my serial number and scope ID.   Here is the text of the post I deleted.   Thanks for understanding...

Wait a few years.  What's available on today's $20,000 scope will be on tomorrows $1,000 scope. :-+

To the OP:  Can you post your hardware version and your firmware version?

Also, I would respectfully suggest that there is nothing you could possibly need to do, or could do with that scope that would need more than 100Mb Ethernet.  Putting it in would have added totally un-nesseccary expense. Jus' say'n. :-//

Ain't that the truth.  This scope is replacing my trusty Tek2245  :-BROKE that I've had since Thomas Edison invented the light bulb.  RIP 2245.  I don't need a scope that much but, in my retirement I've been doing some benchwork and wanted a replacement.  Initially, I purchased a 150Mhz 2 channel Hantek, thinking it would be adequate to suite my basic needs -NOT!   I tolerated it for 2 months then, bought this Siglent.  I must say, in-theory, the Hantek covers all the bases.  It just had a nasty habit of randomly freezing and/or displaying waveforms that didn't really exist at the tip of the probe.   Perhaps you can now understand why I'm gun-shy about oscilloscopes that don't work...

Here's the config (now edited).  FWIW, the tech support person at Saelig stayed on the phone with me while I walked thru the issues and upgraded the scope with the latest version.  He's stumped too.

Ray CI:

All,

When the problems with the scope were first reported, the Siglent support group was responding and asking questions.  Now, it's been several days and a few emails have gone unanswered.   Hmmm, looks like this unit is going back to the vendor.
