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.

Any ideas? I don't want to post this in the software forum because of more traffic. Trying to keep organized and correct.

Probably something in the main PCB broken.
I suggest you give the seller a chance to try it remote.

Edit. Mux looks decent quality from outside pictures, it is 100925?

Yes it is 100925 and is nicer than the previous one. A nicer paperweight...

But now that I have the shop owner hounding me constantly about fixing it, and slow progress and lack of updates from seller... I think I am about to request a refund and forget about it and Mercedes diagnostics. Seriously, is everyone else having better luck with the Chinese units?

1 week reliability is just NOT acceptable.

Sent back to XCar360.com (Steven) for exchange. Will update when they receive it and send the replacement.

(Because exchanges take so long, I also paid for and received an extra C4 mux from xcar360, and it worked just fine with the laptop setup)

So how did this case end up?

Steven of xcar360.com exchanged the whole SDConnect with another one. The one I had was truly broken.
Strangely, the replacement unit had Chinese language on it, and appeared tested, but it seems to work fine. I did a settings reset and it went to English,
xcar360.com is a good trustworthy company, thank you for putting up with me and tens of emails.

Other Chinese companies would have just kept the tool and money (had it happen already).
