Hi Forbes, good news and bad news. Let me start with the good news.
You are not alone! The bad news is the same of the good news, lately, we are having a lot of problems on the ethernet. It looks like the ethernet port has a lower speed (like 200Kbps) or that you cannot even log in it. Does it sound familiar to you? On some site, it can be some EM field close to you. That's why when you try it in your lab everything works magically. You are out of that EM field, and the interference is gone. Even using shielded cable does not help, because it could attenuate the effect not fix at 100%. Moreover it depends if the shield is grounded to the metallic shell of the box, etc. Moreover, I suspect the overall quality of Mikrotik hardware is not very good and it's getting even worse. Suggestions: 1) try shielded cable 2) try some ferrule on the shielded cable 3) test electrical continuity of the circuit from the cable plug on one side to the box (other side) 4) change power supply 5) if you are using an inject/splitter, change it Let us know! Thank you. > We have a tower with a single radio operating on it. We were using a > Microtik 133 board with a single Prizim chipset in it.
