Pluto LAN connection not connecting 99% of the time

Hi,

I observed the same problem today, but my Pluto has the GND modification and I am powering with a 5.2 V / 3A power supply.

So most common reasons should have been avoided.

Make sure the USB to Ethernet adaptor has 5V and not less. You might need to use a USB hub or Y cable to achieve that, don't expect the Pluto to power the adaptor, that's often unreliable.

In my case it is not necessary to supply Pluto with 5V via the second power input. It is powered by the power supply from the Ethernet adapter.

Without problems.

Hello Trevor,

I didn´t made the GND modification.

Hi,

I could solve my problems by adding an additional capacitor at the power feeding point, just 1000yF and 100nF.

The output of the PSU was not clean enough.

I am powering via the Ethernet adaptor only.

So even a PING is impossible?

You know the IP adress of the network adapter? Can you ping it?

Hi Trevor,

you have modified the config.txt with the right IP adress of the ethernet adaptor?

If you power the ethernet adaptor directly via your PC and connect it to the network, did you see the adaptor in your network? Are you able to ping it?

Those IP adress have to be used in the config.txt.

Maybe flashing the Pluto via USB again could solve the problem....

Latest DATV version can be found here:

firmware.hackhamradio.com/alpha/

I´ve given my pluto a fixed IP by entering the IP of the network adaptor here:

[USB_ETHERNET]

ipaddr_eth = 192.168.1.205 (example)

netmask_eth = 255.255.255.0

Do not forget also to enter the IP of the standard gateway of the host.

DHCP can lead to changing IP adresses.....

Hi,

I had similar problems and the reason was defeacted USB to Ethernet adapter.

Sometimes it was working sometimes not.

I verify this when I test it to a PC.

Trevor, I know it is frustrating but when everyone else has it working and you don't the likelihood is you have it wrong, not everyone else. Don't diss something when it's not necessarily at fault.

Does it work plugged in to USB? If so it is your Ethernet adapter. In that case note that not all adaptors are supported by Pluto. I don't understand why you would take it apart and apply 5V. That seems very risky. You need to make sure it is one of the supported ones according to the analog devices website. . https://wiki.analog.com/univer…otg_host_function_support

Don't assume it is because it looks the same as they can be and often are different. Check it really is what it claims to be.

If the adaptor is not the problem, then also why have you loaded F5OEO DATV firmware if you are not doing DATV? This firmware has many great features but it is not for absolute beginners who don't know what they are doing yet. Settings need to be made to work with SDR Console. That's easy to do via it's web interface, but you need to know what you are doing. Stick to the standard firmware for now.

You say you went to have a QSO and it crashed - what does that mean. Did you activate a PTT somewhere? We know the Pluto is sensitive to PSU changes. Hence the ground mod. If by going to transmit you activated a relay that put a spike on the power line it will crash. Try it not connected to anything apart from the PC. If it works there, then that's your problem.

Has it been modified in any way? If it has it's quite possible it has been broken. The USB power chips are easy to damage.

If all else fails, return it via Digikey/Mouser and get a replacement.
