I find these connectors to be among the most reliable connectors
I use. I use them for my home network, as well as various other
places where manufacturer's have placed them (e.g. the IC706 mic
connector in my 4Runner). The pigtail I use to connect my
computer to the network is missing the latc

You are mistaken. RJ45 defines the CONNECTOR.

Unfortunately it's not the plug that gets flogged by the wiggle wiggle

\Replacing the socket of a RJ45 in any piece of equipment that has been
flogged to death is a little more than most Hams can cope with. The

Microphone connectors fail eventually, even the well-made ones with set
screws and clamps.
There is one advantage to the RJ-45 -- it's easy to clip off a little
wire and crimp on a new one.
Replacing a more traditional connector is much harder.

I've seen so many uses that were not adhering to the standard 4-pair.
But the most miserable use is as a mic connector which Motorola went
to. Now I see many ham radio mfr's copying. Instead of molded
multi-contact connector with set screw which holds contact tension

There are 2 wiring standards for cat5/5e/6 cable into RJ45 style modular
plugs: EIA/TIA-568A and EIA/TIA-568B (aka T568A and T568B). They are
slightly different, and both work to gigabit speeds. You can mix them, but
in a data center, for example, they will try to stick with 1 or the other.

That's really the rub isn't it. Awful lot of UNcorrect use out in hamdom.
Not a little by myself, either, before I knew any better.

Never trust an RJ45 cable, it only works if you can prove it works.

I agree with Don. Try a new cable.
It doesn't take a lot of flex to break one of those small solid copper

it is fully seated, and that the plastic spring-tab thingie has

Another thing it could be is a bad connector to cable connection. It can be
intermittent. Another thing to look at is have any of the wires in the jack
been bent. They are pretty flimsy.

You might have a defective cable - get another one and see if the

I have indeed done all the clicks and boot removals and been unable to
resolve the disconnect.
It even happens when the radio is in-use and suddenly has the radio
disconnect from the computer.
So, the only answer is the standard "make certain it clicks", which it does?

Some times the tab has been pressed down and does not spring up enough to lock
properly. I prefer non hooded ends and lift up on the tab before inserting to
bake sure it will click and lock properly.

Hi Byron,
If an RJ45 cable does not make a "snap" sound upon insertion to the socket,
it is not seated properly. Also, what happens very commonly, is that the
little tab on the plug that locks the plug into the socket has been broken
off. Again, VERY common for the tab to be broken off. An RJ45 co
Byron,
There is a latch on the RJ-45 plug - if the plug is inserted
sufficiently, you will hear a slight click when it is fully inserted.
Once latched, it will not fall out.
You may have to move the boot back a bit and push on the plug assembly
itself to get it to latch. Once latched, move
I continue to be plagued with the radio disconnect azssociated with the
RJ-45 interface on the K3S.
Has anyone ever heard of an RJ-45 Pin Alignment tool? I suspect there
is some physical issue that is not resolved by removing the boot and
everything else that I've tried. Forget about it stay
