Ethernet router issues

[Yukinoinu]

I have a bit of a head scratcher. I have a centurylink c2000a router, 4LAN and 1WAN line. Holds gigabyte and connected directly I have that, hard wired through my walls I only get 100Mb/s vs the 1000 I was getting, so wondering if I was screwed over by my contractor (house came present installed with "Cat6") at this point sceptical if they cheated me. I also have another problem with this with wall connection. I have an Nvidia Shield portable. My router isn't exactly game streaming material so I have a mini USB to USB USB to ethernet. It works when connected directly into the router, but connected through the wall in my room, it will not pick up the Ethernet connection. Really wondering what is going on here.

It can be as simple as a single wire not making solid contact with the jack. This is why installs in larger business require certification reports on every jack. They plug in a test unit and verify that that it meets the actual standards.

In home installs you are lucky if they even test at all and then they likely use the cheap testers that just check that there is connectivity at a extremely basic level.

All you can do is look at both ends of the connection and makes sure they appear to be wired correctly. Then the only cost effective thing to do is to try to re terminate the wire to the jack. If the wire is punched directly to the jack just remove it cut off about 1/4 inch and put the wires back. If it has RJ45 plugs that go to a coupler type of jack you will need a special tool to and some new rj45 ends. Putting on rj45 ends take practice so you will likely do it wrong a couple time.....even a profession gets them wrong every now and then which is why everything is tested.

Both the cable and the jacks that the cable is punched down to are supposed to be cat6 rated. However cat5e supports gigabit no problem. More than likely the problem is what bill mentioned with a wire not being tested or loose.

Also I have seen where a second jack was needed in an install and instead of running a new cable, someone takes 1,2,3 and 6 and punches down to one jack and then takes 4,5, 7 and 8 and punches down to a second one in place of the orange and green pair on the same end. Then they do the same thing on the other side. I have seen over the years where this cabling situation would work with 100Mb but not gigabit.

Even if you don't have a cable tester check the termination of your wiring and see if you notice things like this.

Thanks for the reply, I found out today after looking into the face plate that, despite it saying it does support 5 and 5e, it is only really a phone line? It makes sense a little bit and it is false advertising. I get up to 100Mb/s but directly connected to my router, I get 1000Mb/s. I ordered some new plates and they will work for sure.

Hold on. What says it supports CAT5e, the face plates or the actual cable? If the faceplates are CAT5e rated and the cable between them is telephone and only cat3 rated, that is your problem and faceplates won't help. You would need to run a new cable. It wouldn't be as hard as running a brand new though since you could more than likely tape a CAT5e or CAT6 cable onto the old cable and use it to fish up and down your walls.

Both the female jack and the cable should say either CAT5e or CAT6 (there is info printed on the length of rolls and boxes of cable).

no no the face plate is cat3 or some shit. My house was wired with CAT6. I know it is the face plate, I looked up the face plate reviews or whatever I went to, few others had the identical problem. It's hard to explain but it is the face plate and not my expensive ass option to wire CAT6 in the house lol.
