Ethernet interface unreliable - very serious problem [fixed with better power supply cable]
Hello,
I have trouble getting my KiwiSDR I bought though Massdrop last month to connect to the network, as the Ethernet interface continuously disconnects. After some time the orange LED comes on, after some 20 seconds it switches off, to come back on etc...
The problem is intermittent, sometimes it just works, sometimes it won't I have changed cables, used different LAN switch ports, different LAN switches, different cables, nothing seems to cure the problem. This is driving me crazy! I suspect a faulty Ethernet port, but I am not sure.
Any suggestions?
Frans

Are you shure that nobody else using the same IP-address and that the broadcast address is set correctly?

Bjarne,
It does not show up in the IP address table on the DHCP server. It does not even get that far.
Thanks for the suggestion.
Next observation: I booted the Beaglbone without the Ethernet connected: now it does work. I'll need to check whether this is coincidence or a workaround.

I am assuming this is John answering; thanks for your help. I am working with Seeed to solve the issue and have been asked to remove capacitor 162 from the board. If that does not work they intend to exchange the BBG. I will keep you posted.
Again thanks for the kind offer!

I removed the capacitor 162 and now it seems to work correctly.
Thanks for the help, highly appreciated!

We're back to zero: It is no longer working. this is driving me crazy!

I'll see how they respond to my message about the issue returning. Will keep you posted
Cheers,

It is getting a bit late here, so I'll continue some trials tomorrow.
I had it working for some time. Then to see whether it had 'come to life' I rebooted, and the issue is back exactly the same. I powered down, I removed the kiwisdr and tested the BBG alone. With only one exception that seems to work. (10 trials or so). When I reinstalled the kiwisdr the problem is back. It works one out of ten.
The PSU I use is a 12W apple ipad pro power supply. I have also used a battery pack 100% charged on a 2.4 A port. i used this pack to power a raspberry pi 3 with LCD touchscreen without any issues.
I am at a loss.

Thanks for clarifying and helping me to sort this very frustrating issue.
Maybe it is an idea to make this clear to new users before they buy a cable. Or raise the price 5 USD and deliver a cable with the kit, if it is such a critical part of the solution.
I guess the safest is now to first make my own cable. If that does not work, I'll review the PSU.
To be continued!

Youre right! It is mentioned. I never saw that, so I take the blame.

The KiwiSDR has been running for a week now, without any problem. Thanks for the help and this exiting product!
