Boat Electronics/Network Guy

[Mark]

Hey Guys, I know it's not about the capitals, or anything good like that, more fishing/boat related, sorry

I need someone, preferably mobile, to troubleshoot my ethernet network/RADAR. It was working fine, then on my trip down to flag harbor it just stopped. I unplugged all the connections at the box and re plugged them in, and it started to work. Then I notied the other day out in dark it wasn't working again. I tried the same thing, but this time it didn't work. Sooooooo, I figured you guys might know someone, reliable and affordable, and possibly mobile that could look at it and troubleshoot.
Thanks
Mark
