Can't Access Interent
Have a Dell Inspiron 1501 with wireless internet connection that has been working fine. All of a sudden, cannot access internet. All modem and router connections working good and verified through ISP. Wireless connection and internet connection icons show as "connected". Tried restoring computer to a few days ago but nothing changed. All this seemed to occur after attempting to install XP SP3 from the updates. Don't show that being installed. Disabled firewall for time being too. Any suggestions? Tks.

did you restore to a date before you put sp3 on ?

what firewall do you have ?
or ever had a trial version like Norton, mcafee etc

make and model of the pc and the router

does anything else work ok with the router ?

lets see an ipconfig /all

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

I once experienced a similar issue with a Dell laptop... After upgrading to sp3 the wifi stopped working... I never got it fixed and read that the card was unsupported by sp3...This seems unlikely though there should be a fix

AppalBear, sounds like a few things to check. As the one user noted post the contents of you ipconfig/all.

YOUR ISP may say your items are working but it may mean little they are correctly. Try to connect another computer thru it. Did they help walk you through a basic RESET of their provided hardware and did they try and help you through a simple reset of your computer?

You said you updated to SP3, as soon as this was done did it fail? Immediately? It may not be a rollback but a driver issue. Check the device manager "Winkey + Pause/Break key" and show hidden devices while there.

Last or first ditch, you could t-r-y an uninstall of the network adaptor and then reinstall it? It should be all stock settings upon reinstall/reconnect... should be, auto everything......... plug and play. I think thats all it needs /besides an updated driver and UNINSTALLING any other firewalls/similars you have/had running previous. Do those before you uninstall the NIC.

so that does have an IP address

lets see the results of three ping tests and an xirrus screen shot

------------------------------------------------------------------------
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}> CMD to open a DOS window and type:

Type the following command
Ping 192.168.24.1
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

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/

FYI ... computer is a Dell Inspiron 1501; wireless router is a Linksys wireless GHZ 2.4. Did go ahead and assign a value to the IP enable.

if that was when it was disconnected -then its a DNS issue

try this on a PC
------------------------------------------------------------------------

Google public DNS

Google public DNS
http://code.google.com/speed/public-dns/

Theres also a link on how to setup those DNS IP address
http://code.google.com/speed/public-dns/docs/using.html

How to set XP here
http://techie-buzz.com/how-to/google...and-winxp.html

Then once you have set up those DNS entries

Flush & register DNS
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 commands:

Ipconfig/flushdns
ipconfig/registerdns


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

see if that PC nolonger has a problem

Well, I set up the DNS entries per the XP link, entered the two commands (said the flush was successful and that network adapters had been initiated) and then rebooted. But am still getting a server not found message when I try and get on the internet.
