I have a Netgear dualband N Router.
I have three computerson my wireless network , a Lenovo G500 and two Toshibas laptops. The Toshibas each run WiFi at 135Mbps.
If I connect the Lenovo G500 to the router with an ethernet cable it runs at 100.
The router is 15 feet from Lenovo G500. The Lenova G500 on Wifi runs at 65Mbps or slower. Sometimes only at 48Mbps. The speed occurs even if it is the only computer actrive on network .
As a test, I installed a Belkin N wireless adapter on the Lenovo G500 and connected on Wifi 2 and it connects at 135 Mbps. It is only the Lenovo Wireless adapter that slows the G500 down.
How can I increase speed of Wifi on Lenovo?

Welcome to Lenovo Community Forums!
Can you try this and let me know what happened.
Click on the wireless signal at the lower right corner of the screen.
On the list of wireless signals, rightclick on your wifi and choose "View connection properties"
Go to this tab and change the AES to TKIP, then hit ok and Check if the connection of the wireless will change.
Hope this helps

I tried TKIP and the Lenovo G500 went from 65 Mbps to 54 Mbps.

I see, Can you check what is the Built in Wireless adapter in your system.
Open Device Manager and check under Network Adapters.
It may say Wireless or 802.11 or Wireless LAN
Let me know what brand and model it says there.

It lists three under Network Adapters:
Belkin USB Wireless Adapter
Broadcomm 802.11N Network Adapter
Qualcomm Atheros AR8172/8176/8178 PCI-E Fast Ethernet Controller (NDIs 6.30)
Thank you for your help.

Download this first WLAN Driver (Atheros, Broadcom, Realtek) but don't install yet
Make sure you know where to find this later
Now under Device Manager
right click on the Broadcomm 802.11 and select Uninstall.
Make sure to place a check under Delete driver software for this device
After the Uninstall click on view on device manager and select Scan for Hardware Changes.
Note that the Broadcomm may be back under the Network Adapter list
Uninstall it again and place a check under delete driver software.
You'll have to repeat the step until when you don't have the option anymore to place a check under delete driver software.
If that happened click the scan for hardware changes one last time and then Install the driver I asked you to download earlier.
Connect to your wifi and see if that changes anything.

I went to Device manager and it gives me the option to uninstall but I do not see a box to check to delete.
I tried to uninstall multiple times. I also looked at properties of the Driver and it had a date of 5-31-2013.
When I installed WLAN Driver (Atheros, Broadcom, Realtek) I had the same issue the spoeed is 65 Mbps.
I checked driver properties again and it says 5-31-2013 version 220.127.116.11, so I do not think a different driver is active.
Do you know where the optio to check delete is. If it helps I am running windows 8.1. Am I running correct version of the Driver?

I have a similar problem, and I have to use a USB WiFi to get around it. My WiFi is not only slow (5 mb/s and slower rather than 18 mb/s), but the range is only about 12 feet. I've used multiple routers, same problem. I even bought a new internal WiFi card, and it has the same problem. It's been doing this for many months. Any ideas?
