# How much will the length of a CAT cable affect PING?

From the modem, there is about 2 feet of ethernet cable to the router, then from the router there is another two feet to the switch, then about 80 ft to my room where my computer is. i havent terminated the cables yet. and also, they are crossing over some low voltage electrical wires. How will all this negitivly effect ping? because one of the reasons im routing all these cables is because i end up with like 150-200 ping when on wifi.

It should not make too much difference from my PC there is about 20 feet of cable that goes into the first switch then about another 50 to 70 feet down stairs to the next switch then about another 25 to 20 feet to the next PC so that is about 100 feet and here is a log of pinging from one PC to the other.

It will not affect your ping at all. Consider that in order to reach a website the signal has to go from your house all the way to the server and back which is probably a few thousand kilometers. If you have a low ping you should first make sure no one is doing something that will eat up your bandwith like downloading(torrents) or watching (multiple) youtube videos etc.

If you have an older modem you could see if your ISP can provide you with a new one, if your ISP is the one who gave you the modem they should also give you a newer modem free of cost.

Also your low ping could be caused by interference in the wifi signal (a lot of wifi networks close together) or if a microwave/wireless phone is being used altho I have not personally seen that cause a ping of 200ms. If there are a lot of people near you useing wifi you can change your wifi channel using this guide ( http://www.howtogeek.com/howto/21132/change-your-wi-fi-router-channel-to-optimize-your-wireless-signal/ )

Less tan a millisecond. Much less. It may, however, affect signal clarity. But still not by much.

If someone in your house has an adroid phone get a program called wifi analyzer. It'll be your best friend in determining the best singal for you on wifi. I'm not too sure what issue you have with wiring your house but as long as you keep the wire under 100 feet before you boost it again with a switch or router then your perfectly ok in terms of length. The lengh that starts to be troublesome iirc is about 300 feet or 100 meters.

depending on wich catogory cat cable you gonne use..

but its somewhere about 100 meters
