I have a lenovo Y400 And for the last two weeks have been experiencing trouble with the Wireless connectivity. It started 2 weeks back when my wifi connection would suddenly drop or i would be disconnected. The only solution was a restart and this would recur in 20 minutes. I called up lenovo and they advised me to refresh my PC and go back to Windows 8 from 8.1. It seemed resolved for a while and I then upgraded to 8.1. The problem recurred in a week and had to downgrade to win 8 again. I am currently on windows 8 and still have the same trouble ? Is there any solution to this ? The wireless card is the Intel N 2230.
Thanks for the help.
It's a long post and i apologize.
We are sorry to hear you are having connectivity issues with the Intel® Centrino® Wireless-N 2230. Here are a few recommendations you can try for this matter:
1. Contact the http://www.intel.com/support/oems.htm Computer Manufacturer Support and make sure you are using their recommended drivers and configuration.
2. As a second option, you may also use the generic drivers from Intel:
https://downloadcenter.intel.com/download/24655/Intel-PROSet-Wireless-Software-and-Drivers-for-Windo... Intel® PROSet/Wireless Software and Drivers for Windows 8*, version 17.14.0
https://downloadcenter.intel.com/download/25276/Intel-PROSet-Wireless-Software-for-Windows-8-1- Intel® PROSet/Wireless Software for Windows 8.1*, version 18.20.0
3. Go to Windows* Device Manager - Network Adapters, locate the 2230 and go to the "Advanced" properties, then make sure to apply the configuration from the document:
http://www.intel.com/support/wireless/sb/CS-030709.htm Wireless Networking — What are the Recommended Settings for 802.11n Connectivity?
If the issues persist with the most recent driver and recommended settings, please try these actions:
1. Go back to the Advanced settings and apply the following, as they may improve connectivity in the 2.4 GHz band:
- 802.11n channel Width for 2.4Ghz connections: 20 MHz ONLY
- Roaming Agressiveness: 1. Lowest
2. Check with the manufacturer of the access point and make sure you are using the most recent firmware available for it.
3. Set the Windows* power plan setting for the Wireless adapter to Maximum Performance, when plugged in and on battery.
4. Disable Bluetooth* (which also operates in 2.4 GHz). This is normally done with Switch in the PC, or with a keyboard combination; it may also be done in Windows* settings.
5. Check your wireless access point and make sure the security mode of the Wi-fi connection is set to WPA2, and that encryption is AES. Or, you may test if the connections improves with security disabled.
6. Try placing the computer closer to the AP, or in a different position.
