Doing some renovations on the house and we ran some ethernet cables into the rooms. This is the setup we have (see first pic)
Pod.png (1).png



It was only a basement reno so we didnt run cables through the entire house and use a dedicated cse/box to house all the splits like a regular house wire. So the split is housed in the first ethernet wall plate on the left next to the pod.

This is the split in the first wall plate. I have no idea what these little snap pieces are called. Theres 8 of them, one for each individual cable. We did this before the drywallers came in so theres some drywall on the exterior, but im thinking this should be an issue.

So basically we have the pod which wireless connects to the modem, and then you can run ethernet to whatever hardwire you need. The pod supplies signal when directly using it from the pod to my laptop, but when I try plugging the pod into the split and using one of the other ethernet ports in the other room theres no internet available. I do get the "identifying network" for a second or two then it disappears and repeats forever.

Should I just buy a regular 1-2 split and use that? I really hope its not some issue with the cable thats ran through the walls. I used T568a not T568b for the individual cable orientation when installing the crystals, not sure if that effects things.
 
g'day and welcome to the forums. :)

the number of twists in each pair is important.
the orange, green, blue and brown pairs are all twisted at different rates - for a reason.
it looks like you don't have all the pairs mated together, even if you had, the untwisting of the pairs has rendered the cable unsuitable to send data along it.
ethernet cabling is not like power cabling that simply required a copper joining of the wires.

any reason why you didn't run the cables from each room all the way to the 'pod' or move the pod to the split point?
I'd be running longer cables - do you have any floor or roof cavity space to play in, as it may be easier to run up the studs in the wall, into the roof then along the rafters to the pod wall, then down.
 
Hello, thanks for the reply.

"the untwisting of the pairs has rendered the cable unsuitable to send data along it."

I dont understand this part. How are you able to attach a crystal to the ethernet cable without "untwisting" the pairs?
 
you remove the outer shielding of about 50mm of cable and untwist those 4 pairs, straighten them, put them in the correct A or B order, cut them all down to about 12-15mm then insert them into the RJ45 socket, then crimp.
by the time that's done, there isn't too much that remains untwisted, and there is some leeway, but not the amount you have shown in that photo.
plus, on top of that, it looks like the pairs aren't connected right, but the photo isn't the best to go down to that level to 100% confirm that. (and now the phots aren't there!)
