I have windows 7 on a Samsung laptop.
My wireless worked fine for the past 6 months until recently it started to work sporadically. For 2-3 hours it wouldn't work, and then work for another half hour, and repeat etc. Other phones and computers in my house works well, but it's only this computer.


-I have tried to reset my TCP/IP settings through microsoft
-I have tried disabling IPv6
-I have reset my router, modem, and computer, at least 10 times each.
-I have all automatic settings for IP and DNS

Some weird problems are..

-If I ping my gateway, it'll give me any type of returns, anything between 0% to 75%.

-In the rare instance my internet works the connection sign says it is "connected" but above it says no network access or identifying.

-If I run the windows troubleshooting while my internet is not working, it either a) cannot fix the problem b) has a problem with the access point but can't fix it c)just says the internet is working fine, while it isn't.

-My internet status screen says packets are being sent and received, yet nothing is happening in IE.

-My wireless button is totally out of whack. In relation to the screen that pops up if I click it(This is the button on the bottom right taskbar, by the way), a)the button says it's connecting, while my wireless connections says im connected, while "currently connected to" says Identifying...
or b) button is connected, wireless connections says I have limited access, and currently connected to identifying.. And those two are just examples, all 3 can be all different.. yet the internet not work.

-My "Currently connected to" SHOULD be telling me i'm connected to Netgear, with the home network sign. But it has a bench(public network which), saying "unidentified network".
-If I open up a page, it won't load, but never give me the "Internet Explorer cannot display the webpage". It's just loading loading loading and loading.

Crazy not having antivirus and antimalware these days.

Comcast is cable. DSL is telephone company. You have both?

Where is the xirrus screen shot?

start by connecting wired to your router. Do you get internet?

I'm downloading xirrus. I get internet if I connect my wire to my router.

connect by wire and do another ipconfig /all for review

Did you setup the routers wifi? You know set SSID, encryption level and passphrase?

image link doesn't work. It wants me to sign up for imageshack which I have no intention of doing. I think you need to share the file if you want others to see it.

ipconfig looks good except you have no wifi connection.

You should delete your present wifi profile and create a new one with all the correct settings ssid/encryption level and passphrase

I don't know how to upload the file.. It's not much though. There're are two boxes in the connection tab, being wireless and addresses. SSID, BSSID, etc. All 10 of them say N/A.

I've deleted my present wifi profile and created a new one.. Or tried to. I've got all the correct settings, it just won't let me connect to any network now. "Connecting... Connecting... Was unable to connect to a network".

everything indicates your wifi card is not working. Xirrus with all NA's and no connection to any wifi network.

Unit under warranty?

it was working and then it stopped.
looks good in device manager
doesn't connect and xirrus says NA which confirms no wifi action present

This does assume the unit doesn't have a wifi on/off switch that has been accidently set to off.
