Thinking of networking up the house, currently we have just got CAT6 cables coming through the walls, nothing professional or anything.

 

I was attempting to install a (CAT6 rated) faceplate in one of the rooms but couldn't for the life of me figure out why when I did a speed test, it would only get 100Mbps up and down instead of 200Mbps up and down. So after trying to wire it after the 5th time without success I decided to chop off the end and just put a plug on it and now I am getting the full speed.

 

 

 

Does anyone have a checklist of what is needed or should I rather just call a networking company to do the work for us? I don't mind doing it myself but need to know why I was experiencing the problem above, the current CAT6 cables in the house are T568A.

If you aren't familiar with how to terminate cabling and the fundamentals of networking then you might want to utilise an external party to do this work for you.

 

 

 

The reason you are getting 100mbits might be related to your cable and how it's terminated, or you might have a 100mbit only port somewhere along the way.

 

Post more info about your setup and you might get some additional help.

100Mb works over 2 pairs whereas 1000Mb requires all four pairs - a dodgy connection can cause a cable to drop to a max negotiated speed of 100Mb/s

Thanks for the reply, I know the fundamentals I just don't do it often, the simplest way I can explain this setup is below:

Here are some photos of the faceplate wiring when I tried it: https://goo.gl/photos/Pq3MeLS6pYEjAgLfA

Thanks I was thinking that because the second time I wired it it worked at full speed, but then when I moved the faceplate back close to the wall I was getting around 10Mbps download and 200MBps upload.

 

 

 

I also was thinking maybe electrical interference, but I ruled that out as I moved the power cables away and still had the poor download speed.

 

 

 

I think I am not punching the cable correctly into the faceplate even though I have a "professional punch down tool"

 

 

 

I think I either need to try again or just pay someone to do it as I have tried a few times and it's very hit and miss.

Is that solid core cable?

This. It looks like stranded, which wont punch down securely, and will give intermittent connections when moved.

Ah thanks guys that makes sense, I'll get a solid core cable and try that.

Yes it is stranded cable that I am using.

Basically:

 

Solid core for fixed wiring in wall cavities etc.

 

Stranded is for patch cables only (that require more flexibility) and uses different crimp connectors.

Yes, note that there are different plugs for both solid and stranded cable. Also your wiring appears to have untwisted pairs and a damaged IDC for the brown wire, likely from using the krone punchdown. I recommend getting a better jack and proper 110 punchdown tool.

 

I could come and do it if you in auckland. Just let me know length of cat6 to bring.
