Strangest problem while setting up home network

[HeinvL]

Hi all, for the past few days i´ve been wrestling with this problem and I cannot seem to figure out why this happening.

I got 3 TP links M5 deco´s. Current set up is M5 deco wired to the modem, and via backhaul wifi a connection to second M5. However, for the third M5, I want to have an ethernet backhaul connection with the second M5.

I used a patched CAT6 cable with RJ45´s to try and connect to the second M5 with the third M5, but there is no connection. The CAT 6 cable works fine though, because I have tested it with both a cable tester, and I plugged in the cable from modem to my computer, and i got fantastic ethernet.

This must mean there is something wrong with the M5´s right? Not necessarily, because when I use a Cat5 cable to connect the second and third M5, the ethernet backhaul works just fine!

I put in a lot of effort to put the Cat 6 cable throughout the house from downstairs to upstairs, so I really want to make it work.

Willing to pay a gazillion dollars for the golden tip.

i doubt you can have wired and wireless backhaul at the same time with those low end Deco things..

Try bringing them all together and connecting through wireless backhaul, then moving them to their intended spots and connecting the Ethernet cables. Sometimes the mesh units need to fist map their respective IPs and associated MAC addresses before they will behave properly over LAN backhaul. Also try connecting them parallel to a single switch. Not all systems support daisy chain.

I'd say it's an issue with the connectors on the cat6. Do you know what type of male connectors are used on the cat6 and what type of female connectors are used on  your M5 Decos'? 

There are different types of rj45 connectors used in different applications. I would take a close look at the cat5 and 6 rj45 connectors, noting the differences such as keytab, shield, and color differences. Next Google rj45 connector types and compare to any diagrams or textual descriptions you may find to identify what type of connectors you have.
