Hi all.

Newly received SDConnect C4 from a vendor here (kept anonymous for now).

It has worked for exactly 1 week . Device boots up, and isn't recognized by laptop anymore.

My LAN settings are correct, and this device ran on 3 different laptops with Xentry on them, now doesn't connect to any.

   

I tried multiple different LAN cables and no difference. I desperately tried other IP, with no use.



I reconnected the LAN/ethernet card flex cable, and no difference
Not receiving any data back.

   
   

Device firmware is unchanged from original it came with.
I deleted configuration in mux, and still no difference.



Before I get real upset with seller, can anyone recommend anything else?
We all make mistakes and I do as well. I want to resolve this as soon as possible.

What is broken? Seller communicates well, but wants a factory engineer to remote into my computer to check my ethernet settings (above), which I believe are correct.




Background info:
I have used SDConnects for about 6 months now. I am familiar with networking, IP Addresses, Windows computers, and car diagnostics. I have set up Xentry correctly on 3 laptops (9/2015 and 12/2015) and it worked on many cars.

The first mux from Aliexpress in March 2016 (not this one) lasted 3 months before it would not boot fully anymore. It got sent to China, 'repaired', and came back and worked for 1 whole day and didn't boot fully anymore. Bad LUCK. Seller is finally issuing a refund.

So now AGAIN with problems, with this one from another completely different vendor and much more expensive mux.
