Hello Guys and Gals,

I am pulling my hair out on this one so i hope someone can help me out.

I have a new built PC (windows 8.1) which up until now was running on wired LAN. I have purchased an A B G N wireless PCIe card but i cannot for the life of me get reasonable speeds out of it.

When i look at "network and sharing center" I am connected a 130 Mbps however when i look at router stats it showing me my LAN is running at about 56Mbps (and sometimes slower).

I dont have anything else connected to it, i have turned off all encryption and i have even moved my device right next to the router...but with no joy

I have even tried another router and i get the same kind of speeds out of it

Browsing the internet is slow as hell as a result of thi so i am eager to find out were the issue might lay

any ideas?
 
If your link speed is shown at 130Mbit, then you are using single stream 2.4Ghz connectivity (max 150Mbit). This could be a limitation of your card or your router. 60Mbit throughput isn't bad for single stream 2.4Ghz wireless.

What are the model numbers of your router and network card. We can at least identify which is the limiting factor.

I would recommend that you use encryption. Wireless N has been optimized to use WPA2 AES encryption.
 
Thanks Kanewolf

You are correct, i am using 2.4Ghz stream.

My WIFI card is TP-LINK WDN4800:

I am using a router provided to me by my ISP. It is a Technicolor TG799vn v2

I have also tried another router that is running DD WRTbut i have no better luck

Today the connbection seems even worse for some reason!


"Configuration

WLAN Enable: Yes

Interface Enabled: Yes

Power Reduction Enabled: No

Physical Address: REMOVED

Network Name (SSID): REMOVED

Interface Type: 802.11b/g/n

Actual Speed [Mbps]: 5.5

Band: 2.4GHz"

 
How many other access points are sharing the same or overlapping channel?

The more interference there is the lower the signal quality becomes, and the slower the connection. You also have to keep in mind that wireless is single-duplex and will rarely, if ever, exceed 1/2 the stated connection speed.
 


That should be a three stream card (450 Mbit at 2.4 Ghz). It sounds like your router is the limiting factor -- it is acting like a single stream router. To get higher throughput to your router you will need a new router.

What are you using for your DNS provider? You might want to test your DNS provider with namebench.
 
Thanks once again

But i have found the problem...its my 2.4Ghz wireless mouse/keyboard!

I just so happened to be streaming football and to stop my young daughter from playing around with the mouse/keyboard i just unplugged the USB receiver. On doing so i noticed a giant leap in video quality

Just now i ran one of those internet speed websites, clicked GO and then whipped out the USB bit and i went from about 5Mbps to 20...which is me maxed out according to me ISP contract!

So the culprit is my wireless mouse and keyboard and judging by the internets im not the first. Time to invest in something else it seems

Thanks for the help though
 


I will have to keep that in mind for troubleshooting other peoples WIFI problems in the future ....
