Cat5e cable and 500mbps

[NickWilliams]

I have 500mbps speed and a BT smart hub 2. I run a Cat5e cable 50m to an outhouse but only get 90mbps there. Wi-Fi in the house is approx 500. After contacting BT technical help, they told me that Cat5e will not support 500mbps and will only give 100. I have to have Cat6 cable. This advice is contrary to all the info on the web. Cat5e is meant to support up to one gbps up to 100m.
Does anyone have a view please?

Hi @NickWilliams 

Cat5e supports up to 1GB. 

Check your router ethernet settings are not limited to 100 via the port.

@NickWilliams As @Northerner has pointed out, also check your cable, one bad connection and you are down to 100mb/s on the cable, that's all it takes it needs the full 8 cable cores to get 1Gb/s speed and wired correctly off course.

@NickWilliams   what device do you have in your outhouse? Is that capable of 1Gb, or if a switch are any of the devices limited to 10Mbps?

[NickWilliams]

Thanks. I see in my Hub2 settings that there are various options. Not specifically 100mbps but the fastest are selected. The BT/ee technical help people have checked it remotely also.

[NickWilliams]

Thanks v much for replying. I should check my connections and will do this. I was just amazed that BT/ee swore to me that 100mbps is the maximum with Cat 5e and 500mbps.

Thanks v much for replying. In the outhouse I have a WAP but I bypassed this and connected the Cat5e cable direct to the computer, for this test. It seems that the connections must be the problem OR BT/ee are correct.

@NickWilliams The spec of the cable for 5e and there are many many, but it's 100 Metres run at 1Gb/s speed's ALL 8 cores connected. Link below, oops can be when you get like a Pro router 2.5Gb/s nic and alleged fussy about cable type/connection, but not up near that yet and never will be, wired the son's 5Gb/s to a 10Gb/s router cat6 as that was the cable i had lying around!

@NickWilliams As long as you know the device you are using has a Gb/s interface, plug it into the BT router short cable, test the port connection by looking at the properties the nic connects at, then as you said, check the cable out from that port to the area. Your going about it the right way. Jim
