Hello, I have just got FX30, connected it to 24 volts supply. I did “update-rc.d -f enable\_autosleep.sh remove”, but still if I ssh to FX30 in about to 12 hours or so it would close all connection and don’t reply to ping. The only way to get in is do power cycle. Please help, I need it on, so I can ssh there at any moment. Thank you Aleksey. ---

Can it still communicating by AT command? Did you enable still by +cpsms ? ---

Thank you for reply! I’m not sure what you mean. To issue AT commands I have to ssh to fx30 and then run " microcom /dev/ttyAT" . My powermode is “!POWERMODE: No request, status=9-PSM disabled” and when I see “client\_loop: send disconnect: Broken pipe”, and I can’t even ping FX30 anymore, then I’m not even sure in what mode it is now. So unit is generally not usable if it goes down and need power cycle to turn back on. ---

if its USB conects to windows, it should enumerate the modem/NMEA/DM port in device manager, did you see this? ---

Hello, Sorry I’m confused. When I connect USB to Linux it creates 3 /dev/ttyUSB crw-rw---- 1 root dialout 188, 0 Apr 10 12:27 /dev/ttyUSB0 crw-rw---- 1 root dialout 188, 1 Apr 10 12:27 /dev/ttyUSB1 crw-rw---- 1 root dialout 188, 2 Apr 10 12:27 /dev/ttyUSB2 and I put dmesg output from this event . Something is missing? Thank you Aleksey. ---

what do you mean by “something is missing”? Can you do AT command communication in /dev/ttyUSB2? ---

I will check can I do it or not when it does not reply to ping ---

OK, ping is not working AT commands do work “!POWERMODE: No request, status=9-PSM disabled” What I need to do to check why network is down and how to keep it up? ---

Did you check “cm data”? You can write a script to check network status, if it is down, then make it up again ---

For that I need ssh to FX30, and I can’t do this with network down, and that exactly the problem I trying to solve. In real system I would not also have usb . So only AT commands fro linux USB port are working . ---

then what do you expect here if you cannot further debug with ssh? Probably before you deploy in the field, you need to run a script to continuously make the module online: ```auto connect_data() { while true; do ret="$(cm data | grep "Connected" | awk -F '[,]+' '{print $2}')" if ["$ret" = "no"] then echo "Data channel is not established!" cm data connect & sleep 5 else echo "Data channel is now established!" break fi done } while true; do cm radio | grep "Signal" ping -q -c3 google.com > /dev/null if [$? -eq 0] then echo "OK to ping google server." else connect_data fi done ``` ---

Sorry, you are talking about modem connection. For now I don’t care about modem at all, I need Ethernet connection to FX30 all the time and not depending on connected state of modem. ---

No it’s also dead, AT commands are working, may be there is a way figure a state it is on ? [Next page](https://forum.sierrawireless.com/t/fx30-going-down/29450.md?page=2)
