wireless speed question

[sample text]

hey,I pay 15 dollars for 100mbps internet connection and when I use ethernet cable on my laptop,the speed is 100.0Mbps,but when I'm using wifi,the speed is 72.0Mbps(I have all drivers up to date).Is it because maybe my router is bad?If the problem was in the network card,even on ethernet connection my speed would be under 100Mbps then

No. It could just be a slowdown by your provider because of increased usage at that time. Also, Wifi signals drop slightly if there is wireless interference, or just plain objects in the way. 72 Mbps should be plenty for whatever you are doing though.

what frequency range and wifi standard are you using? 2.4 GHz or 5 GHz 150N, 300N, AC ?

technically, wifi and ethernet are different and independent devices.

even when they are both on the same card or integrated onto the mainboard

2.4ghz

I find that hard to believe. With a theoretical maximum of 11 mbps and (a least what i get) maximum of 10 mbps, you would have to be on the 5GHZ band. However, try switching to the 5 GHZ band if by some miracle you get those speeds on 2.4 GHZ. 

 

 

Looking at the post a little bit closer, i saw that you said you pay $15 a month for that kind of service? Where are you located?

2.4GHz has a maximum speed of about 300 to 600Mbps on 802.11n if the conditions are near perfect.

11Mbps is the maximum for old 802.11b standard.

Any device that I have seen that supports 2.4 GHz 802.11b also supports 5 GHz which is better all around (unless you have extreme distances of over a few hundred feet in which case an extender works just fine)

Umm, you're confusing the bands. 802.11n is the standard that supports 2.4GHz and 5GHz

802.11b and g standards are 2.4GHz only.

72Mbps is about right for a device in the 2.4GHz range with single band 802.11n which is what I suspect you've got but I could be wrong. If you can give us model numbers that could help narrow things down and confirm/deny suspicions. Additionally wireless speeds are impacted by distance, interference, and other factors as well compared to ethernet. How far away from the router are you and do you have a lot of other wireless devices or networks around you?

802.11B has been dead for years. Wireless G that also used 2.4 Ghz would do up to 54 Mbps. Wireless N came in 150 Mbps - 450 Mbps flavors, Ive seen AC devices do any from 300 Mbps - 900 Mbps on 2.4 Ghz. Technology advances forward every few years dude.

Wireless has a lot of things that can interfere. Walls, other devices using the same band and such can cause slow downs. Also, the further you are from the router the slower the connection speed can become. In order for the router to keep a stable link, mostly at a distance it will favor slowing down the connection speed to keep the link reliable. In some cases if you have a lot of devices connected to one band it can slow the router down as well. 

 

If you need speed, then use Ethernet. If you can deal with slower speeds then WiFi works just fine.

router=Dlink GO RT N 150
laptop=lenovo g505(quad core)
my laptop is in the same room with the router,even less than 1 meter from each device.2 phones,my laptop are connected wirelessly and 1 PC is connected via cable to the router

That router can talk or connect to devices like wireless network cards at maximum 150 mbps . which means you'll have a maximum theoretical upload and download speeds of 72 mbps in each direction. That's ideal situation, like having the modem and antenna of your wireless card at around 1 inch distance between them, and no other wireless signals around.

 

So I guess your wireless card finds a strong enough signal to connect and stay connected at maximum speed (72 mbps in either direction) and that's pretty much it.

There's alot of factors in play here, but most of the time its a signal issue. In your case, i suspect its just your wifi card inside you pc being the limiting factor for the weaker Mbp.

 

Regardless, the slower download speed doesn't mean much unless you are constantly downloading something or streaming at 4k standard. What will make or break a wifi user is disconnecting constantly, if you aren't then you are good.
