I'm pulling my hair out :(

I've just re-wired my house with Virgin Modem linked to a Asus RT-N56U Router in the lounge.

I have a NAS pluged via 1m cat5e in to port 1 and two Bedroom PC's via 15m cat5e in ports 2 and 3. NAS, Router and both PC's have gigabit ports. Port 4 as a switch on it and is distributed between consoles and media players.

Cables being used are all brand new and I have carefully routed the cables to bedrooms under floorboards etc. (took all day)

The problem I have is both bedroom cables are only working at 100mbps instead of 1000mbps(gigabit). After much testing I've come to the conclusion that both 15m cables are ****!

With the aid of a switch and 2 x 5m cat5e cables I managed to link a bedroom PC down to the router by trailing the cables round the house and got a gigabit connection. So must be the cables (am I right?)

Is there anything I can do with the existing cables so as I don't have to go ripping floor boards back up? If I do have to buy new cables will buying cat6 cables be a safer bet and will they work with the rest of my cat5e network?
 
Guys, these are moulded cables that i just have sticking out from under the carpet, I know it's not proper but for now it will have to do.

I don't have a crimping tool, Would it be worth buying one and putting new RJ45's on?

Like I said these are brand new cables, is it possible that they are too long or is it more likely the plugs haven't been crimped on good enough?
 
If it helps this is what the cables have printed on them.

E-TIME DATA CABLE CAT.5E UTP 24AWG 2PAIR AWM 2835

I'll try anything that helps me not take the house apart again!!!!

2PAIR?

That would suggest the cable is missing the 3rd and 4th pairs required for gigabit communication.

Any chance of a photo close up of one of the connectors to confirm?

Sorry about the quality!

What NAS

How are you telling that they are only running at 100Mbps?

I have a ZyXel NSA310 that is capable and i've had 42MB/sec out of previously.

I've tried copying a single large file of 6gb from the NAS to each bedroom PC and only get 10MB/sec

I've also clicked on Local Area Connection Status and it says "Speed: 100.0 Mbps"

I've also tried changing auto-negotiating in drivers to 1 GBit but it made no difference.
 
Just checked the cable in the other bedroom and it says 4 Pairs, Also did a test using 2 TP-Link 4 port switchers by putting a switch at either end of the cable and seeing what colour light it gives (Green=1000Mbps and Orange=100Mbps)

Bedroom one - 15m 2 Pair cat5e, Switch = Orange

Bedroom two - 15m 4 Pair cat5e, Switch = Green

Despite this both PC's show as 100Mbps in Local Area Connection Status and can only copy a large file at 10MB/sec.

This is why I'm pulling my hair out!
 
So should I bite the bullet and just buy 2 x 15m Cat6 cables just to be sure?

I'm thinking if I was to start buying cable testers, crimpers and whatever else and it still didn't work i'd have to go out and buy new cables anyway :(

Thanks for your help though guys
 
Another thought...
The cables run along side electrical wiring under the floor boards, could this possibly degrade performance?

Also should I go for 15m FTP (foil twisted pair) cat5e or for a little extra cat6 FTP?

Any reason why you aren’t installing solid core cable between faceplates?

The Wife doesn't want me to add boxes/make a mess until we next decorate. My plan would be to use the existing wiring and install faceplates then.

Knowing That I will have to cross electrical cabling a couple of times and I need to achieve a Gigabit connection over 15 meters, if you were me what Cable would your purchase and any particular brand ?

thanks :)
 
I've decided to go with Cat6 UTP snaggless cables, it's costing me less than £50 inc. for 2 x 15m, 2 x 5m, 8 x 1m and 2 x 0.5m cables. These will replace every single lead I have and as they're Cat6 I'm kind of guaranteed 1 Gigabit as long as I have Gigabit capable devices ( which I have)
 
I've got cat5e cables now and I'm not getting Gigabit speeds and tbh I don't mind paying the extra £25 for piece of mind and for whatever the future brings!
 
Update..

Cables arrived today, did a dry run and plugged one end of the cable into bedroom pc and other in to router and can confirm a 1 Gigabit connection :)

The cables are quite rigid but feel decent quality although the inflexibility of the 0.5m cables might be a problem!

I'll wire it all up tomorrow as I finish work early...
