Thinkpad Edge E430 Wireless speed only 72Mbps

Hi,

 

I recently bought a 300Mbps Wireless N Router (TP-Link TL-WR841ND), but I only get 72 Mbps speed on my Thinkpad E430 laptop. As far as I read, the 1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter only supports speeds up to 150 Mbps (which would still be ok with me), but instead I get 72 Mbps. I tried to tweak the adapter and router settings, but I had no luck.

 

Do I need to change the Wireless adapter? Is it possible to change it, or should I use an external USB Wireless adapter instead?

 

Thank you!

Hi Tudorc,

 

Welcome to Lenovo Community Forums!

 

I would suggest you to check if any other similar device is able to achieve better speeds.

 

Log to the router's configuration utility by typing its IP address into a browser and change the encryption settings to WPA2 Encryption Only. Choose 40MHz-wide channels in the router’s configuration utility.

 

Since you are using a 1x1 single-stream card, so a max of 150Mbps is theoretically said to achieve. In addition, you are only on the 2.4GHz band, which is often congested, so you may see lower speeds. The disparity between theoretical and practical Wi-Fi performance comes from network protocol overhead, radio interference, physical obstructions on the line of sight between devices, and distance between devices. Under ideal conditions, actual results for a wireless adapter rated at 150Mbps is perhaps in the range of 50-80Mbps.

 

Hope this provided enough clarity for your query!

 

Best regards,

Mithun.

Hi Mithun,

Thank you for your reply, The router currently uses a channel width of 40MHz, there are no physical obstructions between the router and my Thinkpad and the distance between them is usually under 2m and yet the speed displayed in the Wireless Network Connection Status is 72.0 Mbps.

Best regards,

Hi Tudorc,

 

It looks like a decent and standard speed for me as per the router and wireless card configurations mentioned.

Well, the router supports up to 300 Mbps and the wireless card up to 150 Mbps. My internet connection is 100 Mbps, and I thought I could reach that speed without having to change my wireless card..
