local and internet

Hello Tech support forms hope your having a great day/afternoon/night im not :(, my computer is a laptop and its about 3 years old. Ive been experiancing problems with my internet connection...It seems that it is fluctuating between local and internet to just local every 5 minutes or less. Usually I fix problems with my software no problem this time I cant figure out whats wrong but I fear this could be a hardware malfuction, and repair guys are priceyy. Its been doing this for a few days now.

any other devices on the router effected ?
make and model of the router
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

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

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/00475A/XirrusWiFiInspectorSetup.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-Inspector/xirruswifiinspectorguide1-2-0.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 and use the Manage Attachments button to upload it here.
Full details are 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.

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

This is the craziest thing, I braught my laptop downstairs for the first time in 6 months, and now its internet connection is 2x stronger and it hasnt cut out... There must be something between this floor and upstairs that is interfeering with the connection, but I dont see how because its been like that for 5 days now and hasnt cut out before..

try logging into the router and changing to channel 6

the signal strength looks OK on all the xirrus screenshots

and if you are still getting a reply when pinging 192.168.1.254 from upstairs and down stairs , then you are connected to the router
so that does not make sense that it does not access the internet
