can your ethernet cable afflict your wireless network speed?

Question

if you use a cat 5 ethernet cable instead of a ca6 or 7 it can increase your network speed if you run it on long distance (exemple: cat5 cable will not give you a 1gbps speed if it's more than 100 meters long)
but what i would like to know is if an ehternet cable of a hihger category can increase your WIRELESS network speed because my router ( http://www.asus.com/Networking/RTAC68U/ ) should be able to give a wireless speed of 1.9gbps and if i put my cat5a cable in it the wireless speed is around 150mbps and if i put it directly in my computer i still get the 1gbps
am i doing something wrong? or should i get a better cable for the higher wireless network speed?
anyway the router should be able to give my the 1.9gbps wireless speed as it says so on the site and the box

Answer 1

Broadcom® TurboQAM™ technology increases wireless-N data rate to

600 Mbps



the throughput of the router can theortically reach 1.9gbps

the wireless has a maximum of 1300mbps with ac wireless.

you need a wireless adapter capable of the 1300mbps ac signal.



802.11a : 6,9,12,18,24,36,48,54Mbps

802.11b : 1, 2, 5.5, 11Mbps

802.11g : 6,9,12,18,24,36,48,54Mbps

802.11n : up to 450Mbps

802.11n TurboQAM：up to600Mbps

802.11ac: up to 1300Mbps

Answer 2

No, by definition wireless is without wires and so your Ethernet (wired) connection has no bearing on your WiFi speed. Additionally, Cat5 isn't rated for 1Gbps (though it might work), you need Cat5e or better.



A couple other points: That 1.9 Gbps is the maximum bandwidth under perfect situations. You will probably get less than that for throughput (maybe closer to half, but I'm not up to date on 802.11ac). Additionally that is only if your WiFi adapter on your device supports 802.11ac (probably with 4x4 mimo). So if your laptop only has an 802.11n card in it (or is less than 4x4 mimo, which is probably is) you will be using 802.11n data rates. A rule of thumb in communication, both sides of the connection have to have a protocol in order to use it.

Answer 3

wired has nothing to do with wireless. 2 different PHYs.

you can consider those to be separate parts of the same LAN.



you can't compare wires to wireless. it's like comparing apples to oranges. and no it's not 1.9GHz. that's marketing talk. 802.11ac is 1.3Gbps max on the 5GHz band. just to make things sound more impressive, they add up each band it supports... (you are not supposed to, it doesn't work that way, but again it's marketing's lack of understanding of technical stuff) like the 2.4GHz band, which would have 1.9Gbps-1.3Gbps=600Mbps (trying to extract real numbers out of the marketing junk).



cat5a doesn't exist, you bought the wrong'y spec'd cable. do you mean cat5e? cat7 is just really really thick from shielding and probably hefty expensive too... usually only backbones and ISPs need that much bandwidth.

are you just throwing out terms to throw out terms?



cat5 is 100Mbps max. if you have 100Mbps internet, this will work for you. if you have gigabit internet then you need cat5e or better yet cat6. if using wireless-ac you should use wireless-ac only adapters if you want full speed (avoid USB 2.0 adapters which is all that's available in ac right now, it's got a 240Mbps bandwidth cap (1/2 480Mbps USB 2.0)).
