Did you try different ethernet cable / switch ports? 99% of network problems are due to crappy cables / bad connections.

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.

I would agree ... Return it within time , and note the serial#.
Especially now when "support" has gone quiet.

I have the same model that i love , and it has no issues..
Well it did forget to renew DHCP , but siglent fixed that in next FW release.

I would still recommend it , just get another ... With another serial#.
Yours must be a "dud" ...

Be assured, there is nothing wrong with the LAN (famous last words but, please trust me on this).  The issue has been replicated on two (actually three) totally different LAN environments.

1)  Only Static IP addresses and LAN configs work.  DCHP is a no-go with intermittent 50 to 100% packet loss.
2)  The timezone keeps resetting to UTC if the unit is powered-off via menu or warm-switch.
3)  The LXI LAN Reset option does not do a HW reset on the phy port (never drops carrier) as I would expect; instead, it set the flags in the LAN configuration for "Auto DHCP" back to enabled status.
4)  After saving a configuration (timebase, some channel configs etc) then, doing a power-down followed by restoring the configuration, some of the screen characteristics are not restored.  e.g. Beep-sounds, menu auto-hide and some channels that were enabled are no longer enabled.

3. Have you tried Tek mode for coms ?
4. How are you shutting down ?
It should only be a 2s press of the power button and then let it save settings. If you hold the power button down this becomes a hard power OFF and settings will not be saved.
Menu Autohide is disabled in FW V1.5.2R2 after some strong insistence to Siglent about this annoying feature for a new user. Early firmware only kept menus up for just 5s.

Thanks for the kind ideas but, it's been tried on 2 separate LANs with 3 different routers.  FWIW:  I've written firmware for dozens of products ranging from LAN equipment to large scale core Internet interface cards...  LOL:  I got a pretty good handle on my home LAN  8).  I sniffed the traffic and the DHCP is simply broken. Thanks for the kind suggestions.

KungFuJosh:
If the issue isn't what Rob (Tautech) suggested above about pressing the power button too long at shut off, I would return it and get a new one. The SDS2000XP series is a great scope, but if you've got a bad unit, don't waste more return window time on it.
