Hello All,

I have a 999 at console, 959 at bow, terrova I pilot link, and 360 (mounted on front of boat by trolling motor but on a seperate mount) all connected to 5 port ethernet switch. I have had this for roughly 4 years and all working fine. In the past i would occasionally get "360 sonar source lost" when I would stop 360 pinging and pull 360 out of the water and move to new spot. Never really was a problem, just selected "no" to the "360 sonar source lost" message. Move to new spot, deploy 360 and start pinging - no problems really.

Now, I keep loosing ethernet connection with 360 to the 959, but it will connect back up and the 360 will start working again. I tried to start pinging thru the 959 like have always done in the past, but will not start. I can start pinging from the 999 and it will start and I can get the 360 on view on the 959. I did loose shared waypoints on the 959 once, along with 360 but connection came back a few seconds later. Seems to lose connection the most when I move to another spot (stow terrova, pull 360). I don't think I lose ethernet connection between 360 and 999.

I have done the procedure for a "stuck IP address" - disconnect all ethernet, restore defaults twice on each unit, and connected/set up ethernet.

Seems like the problem lies with the 959? I'm not sure though. Ehternet cable, ethernet port, ethernet hub, or the 959 unit itself?? Any thoughts?

Sounds like either a faulty Ethernet cable or a faulty port on the AS ETH 5XPG ...

Move the 959 Ethernet connection to the open port on AS ETH 5XPG and test ...

If the exact same issue still occurs it’s most likely the Ethernet cable ...

I have also had odd network issues in my boat and after much observation I determined the ethernet switch kept restarting. After more research I figured out I had too small of wire run to my fuse bock, thus I was having low voltage issues with the switch and other devices.

Not sure that's your exact issue, just something to think about.

Thanks Rickie and Spydude for the responses. I will try the open port on the ethernet switch. I also noticed when out on the lake and trying to troubleshoot the problem, that the 959 showed 11.8 V and the 999 showed 12.3V (with main motor off and had been fishing for 1/2 hr). Those voltages did go up when I turned on the main motor to move to new location. I am wondering if it could be a voltage issue as well - both ethernet switch and 959 power are robbed off of other circuits close by. I have wire ordered to fix this.

Thanks again!

Definitely look into a power issue ...
