I have Norton 360 utility on the computer and disabled the firewall and still same issues.
use the removal tool to get rid of norton you can always re-install if you have a full subscription to the norton service - make sure you note any subscription keys needed

would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
Make sure you also indicate on the reply which tests are for what condition.

please include the xirrus screen shots for both conditions - see how below.

------------------------------------------------------------------------
ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

We would like to see the results from an ipconfig /all - post back the results in a reply here.

This should also work for windows 8
Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will now be highlighted
Next
From the notepad menu - choose Edit - Copy

Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
The results from the notepad should now appear in the forum reply.
------------------------------------------------------------------------

------------------------------------------------------------------------
Ping Tests
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply

Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

For Windows 8
to open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.

Type the following command
Ping {then a space and then add the number that is shown against the item labelled "default gateway" shown in the results from the ipconfig /all}
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Type the following command
Ping google.com
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Type the following command
Ping 209.183.226.152
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste
For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.

Run Xirrus Wi-Fi Inspector
Download and install

If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.
You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

{If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need will need to have NET Framework installed for the WiFi Inspector to function.
On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

Run the program

A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus-Wi-Fi-inspectorguide-1-2-1-RevB-6.aspx

post a screen shot of the program running.
if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information.

post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)

To post a screen shot of the active window.
1) (For windows 8 see below) hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
OR
2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
Full details are available here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot


Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
note: the signal level is a negative number, so for example -88 is worst and -40 is better

If you are using the Mac OS then use http://www.istumbler.net/

if you want to optimise base station position and signal strength / dead spots use
http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

For windows 8 - I dont have windows 8 and not tried - but this should work

1) MSPaint is only available in classic desktop mode and can not use this program with the new Windows 8 start screen.
You can find MSPaint by typing “mspaint”, which will search and allow you to install.
MS "Fresh Paint program" is for Windows 8, download free from the Windows 8 store.

2)
>Open Snipping Tool (From the Windows 8 Start Screen, type "snip" and press enter.
>Press the Esc. key.
>go back to your Windows 8 start screen - Swipe from left or press Window Button
>Press Ctrl+PrntScr button to use Snipping Tool

log into the router and change the wireless channel used - you have potential interference from "direct-p7...."
change to channel 6 or 11
