sayan8723,

Can you run Network Interface and post the information back here?

Rick

Here it is....

There is 1 interface on the system:

    Name                   : Wi-Fi     Description            : Intel(R) Centrino(R) Wireless-N 2230     GUID                   : 40562b87-db89-4a88-a451-d423bce5c748     Physical address       : 00:c2:c6:0a:36:10     State                  : connected     SSID                   : SAYAN     BSSID                  : 00:24:8c:ec:41:79     Network type           : Infrastructure     Radio type             : 802.11g     Authentication         : WPA2-Personal     Cipher                 : CCMP     Connection mode        : Profile     Channel                : 2     Receive rate (Mbps)    : 54     Transmit rate (Mbps)   : 54     Signal                 : 94%     Profile                : SAYAN

sayan8723,

Switch the type of security to WPA-PSK(TKIP) Security)Personal) I would make a new SSID to make connecting easier.

Also change the channel to 1, 6 or 11. I prefer channel 11.

Rick

Hi Rick,

Thanks for you reply. Sorry for my late response as I was out of town for a month and I am back home now. I created a new SSID with type of security to WPA-PSK(TKIP) Security)Personal) and tried all the 3 channels- 1,6 and 11, but still looks to be the same results. At times, I am able to connect to the WIFI network  using my Dell laptop and work for only about 5mins on that, after which the entire WIFI network is blocked and it stops working on all devices connected to it. Also, another observation is that while connecting to the WIFI network I am getting an IP of 169.254......... Wonder what the issue is? Really frustrated with this.

sayan8723,

The 169.254 IP Address is a communications problem with the router(s) communicating.

Power off your ISP modem/router and your wireless router(if any) for 30 seconds. Then power on the ISP modem/router. Wait 15 seconds, then power on the wireless router(if any)

Restart the computer and try to connect.

What happens?

Rick

Do you have a microwave placed nearby to the router as microwaves or such other electronic devices blocks the signal. 

Please reply so that I can provide you further steps if above solution doesn't works.

I did a hard reboot of the router but that did not work. Also, there isn't any electronic devices located nearby which might be interfering with the Wifi signal

sayan8723,

You changed the channel?

Are you using the Intel ~ Recommended settings for 802.11n connectivity

Rick

What is your current network security mode?
