Me and my friend have both two exact the same laptops, bought from the same shop at the same day and I decided one day to go wireless because I forgot my ethernet cable to the LAN party (with a few other laptops but this question will be specifically about these two laptops).
I downloaded connectify, a tool which utilizes the windows
netsh features to create a Wireless Accesspoint from my laptop.
Both laptops have a
Realtek RTL8723AE Wireless LAN 802.11n PCI-E NIC and the same, newest and updated drivers running on Windows 8 with a Core i7-3630QM (2.4-3.2ghz 8 logical cores / 4 physical) Processor and 8gb 1600mhz RAM.
From what I know the 802.11n technology has a theoretical speed limit around 300 Mbps ( 37.5 MB/s). Yet the speed achieved when directly sharing a file from the first laptop to the second laptop is 16 Mbps ( 2 MB/s ). This is an utilization of ~5% and not even near the speed of 802.11g, not to mention 802.11n…
- Where is my remaining 95% of the speed 802.11n offers?
- Why is the connection so slow?
- Is the 300 Mbps speed of 802.11n just a big marketing scam?
I also tried following this tutorial but the results were exactly the same.
The gigabit ethernet works really nice, we get speeds around 75MB/s ( 600 Mbps ) [peak: 115 MB/s].
Also, please note: the laptops aren't even 1 meter from each other and no other devices were connected to the network access point.
netsh wlan show hostednetwork command, as requested, shows:
C:\windows\system32>netsh wlan show hostednetwork Hosted network settings ----------------------- Mode : Allowed SSID name : "xxxxxxx" Max number of clients : 20 Authentication : WPA2-Personal Cipher : CCMP Hosted network status --------------------- Status : Started BSSID : 20:68:9d:59:65:94 Radio type : 802.11n Channel : 13 Number of clients : 0
My friend came over with his laptop and I took a screen of my laptop stuff:
And suprisingly, a screenshot from my friends laptop:
The speed stated is 54Mbps (we achieve ~28 Mbps in the screenshot), however in our driver configuration we have both 20/40mhz bands enabled and
n mode too.. I cannot think of a reason why the network would choose the slower variants.
Is there a way to fix this?
