Solved: Connection dies after some time
Hi

I'm having trouble with my internet the past few days, I'm connected to the internet via wifi and after browsing some minutes it will tell me unable to connect (using firefox and other explorers). In order to continue browsing I must refresh the page several times and it will load without pictures.

I'm using win7 home premium and it's the only computer that presents this issue. I've tried pluging the computer directly to the router, but it gives me the same results. Also, I've scanned the computer for malware with MCafee, but it shows nothing.

any help would be appreciated a lot.
Thanks in advice.

would you post the following tests when its working OK and then repeat ALL the tests when it disconnects and make sure you also tells which tests posted are for what condition

if you are also connected by wireless include the xirrus screen shots

Please post back here the make and exact model of the router and if separate, the make and exact model of the modem

Also please make a note of the status of the light on the modem and on the router when working normally - post back here and then when disconnected post the status of the lights here again if changed

------------------------------------------------------------------------
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 results here

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

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 to notepad and then automatically open notepad.

Now all you need to do is copy and paste those results to a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will be highlighted
Next
From the notepad menu - choose Edit - Copy
Now go back to the forum - reply and then right click in the reply box and paste
------------------------------------------------------------------------

------------------------------------------------------------------------
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 results 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.

Start> Run {search bar in Vista/W7}> type CMD to open a DOS window and type:

Type the following command
Ping {plus the number thats shown against the default gateway shown in above ipconfig /all}
Post back the results
rightclick in the 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
rightclick in the 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 results
rightclick in the box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste
Quote:
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 , one by name and one by number which checks that the dns is working

------------------------------------------------------------------------

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 paste here.


http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
Direct link to the program is here http://wpc.475a.edgecastcdn.net/0047...etup.1.2.0.exe

{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 NET Framework installed for the WiFi Inspector to function.

Run the program

A user guide is available here http://www.xirrus.com/Products/Wi-Fi...uide1-2-0.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, and also post which network "Adapter Name" (1st column) is yours on the list

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
Full details are here http://library.techguy.org/wiki/TSG_...g_a_Screenshot

Or if you are using Vista/Windows 7 you can use the "snipping tool" which is found in
Start> All programs> Accessories> Snipping Tool

Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

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