LAN Network Slow (Should be 300, it is only 30)

[Peter_26]

I recently upgraded my service to 300 mbps. My office is configured so that the router is far from my work area. When I use a speed test from the my work area, it is 30 mbps. When I connect my laptop directly to my router is around 300 mbps. So i figure it is either the cable or the switch I am using. I am currently using a 100 ft of CAT 5e cable. I tried plugging the 100 foot CAT 5e cable directly into my laptop and still clocks around 30 mbps. My first question is what kind of LAN cable should I be using? What kind of switch should I use for higher speeds? My laptop has the following network card installed: Qualcomm Atheros AR8152 PCI-E Fast Ethernet Controller.

Well what happens if you use a shorter cable into the switch? That will eliminate the switch as the problem.

You will need to have at least a Cat 6E cable.
And will need to check what the limits of the Ethernet port on the computer can run at.
A cat 5E cable should be no longer than 90 to 95m from end to end.
Due to the length it will struggle to reach the quoted 300Mbps, and because it needs to be a Cat 6E quality cable.

Remember 300Mbps has to be divided by 8, to get the Megabytes value.

you need to check if speed test was quoting the value in Megabytes per second.
It will be the confusion between bits, and bytes as to why you think you are not getting the true speed.
So if it`s 37.5 MB then you are getting the correct speed. It`s the conversion from Mbps bit`s to bytes that is confusing you.

Please quote you source for this information....it is completely wrong.

Cat5e is rated to 1gbit to 100meters. There is no such thing as cat6e. Cat6a is used when you have 10g interfaces in your equipment. Even if you use cat6a or cat7 the limitation is still 100 meters.

A 100ft cat5e cable will easily handle the traffic......why it does not likely is a issue with that particular cable.
