Hi
I had previously bought a cheap router ($50) so I can setup a wireless network in the plant.
The plant had say 4 PLCs and 4 SCADA clients and a few HMI displays. I wanted a wireless network so I can take my laptop around freely.
When I connected the router to the network I was struggling to ping any PLC. Sometime I get latency of 2000ms, sometimes 5ms and sometimes I couldn't ping anything. I decided to disconnect two of the PLC to see if too much network traffic is affecting the wireless router. Turns out it was the issue, the wireless router couldn't switch fast enough. I went and exchanged this router for a much more expensive one ($200+) and everything worked fine.
I would like to learn are there any key specs I need to focus on when buying a router that will be used in a heavy traffic network? Instead of focusing on buying an expensive one.
