Unhappy Rare On and Off Wireless: No clue to what's wrong with my computer!
For a while now when I try to connect to my wireless router (Netgear WNR1000) It says "Identifying..." for a while, but then it will disconnect . My wireless only works sometimes if I reset the router every once and a while. Even then it will connect properly with my computer for two days tops. The wireless works on the other computers in the house, just not mine. I've checked all of the wireless settings to make sure they match correctly to the network and I have no idea what to do to fix this problem (or even what the real problem is).

I've looked up a lot of ways to fix it and they haven't worked, so I really hope you guys can help


Also, If it helps I have a Lenovo T410 with Windows 7 Professional with a 32-bit Operating System

Thanks

All the other devices connected to the wireless work perfectly ALL the time - corrrect

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.


What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG etc

------------------------------------------------------------------------
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.

We would like to see the results from an 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 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.
------------------------------------------------------------------------

Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box

Type the following command
Ping {then a space and then add the number that is shown against the item labeled "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

then reply here and

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/fil.../download.html}

Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need will need to haveNET Framework installed for the WiFi Inspector to function.

Run the program

A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus...-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) 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_...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. "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/ 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

Are you part of a domain?

Is there any other computer on your network with the same IP address (192.168.1.3 in this case)?

I'm part of a domain, but none of the other computers on the wireless network have the same domain name or IP address.

this is a PC you have purchased from the school and use for school work - yes

i would expect the domain name to be the same for the school or at least for a section of the school

you do mean domain and not user name ?

these disconnects where do they occur - just at the school or on any network ?

I dont know how the schools work in US - in UK they belong to the student who then use them at home

Yes I mean domain, and for some reason the wireless works perfectly at the school, but not at my house...

I use it at home most of the time though so it's still an inconvenience.

Make sure you have the latest wireless driver from Lenova's web site.

Why are you using WEP? Try without encryption. If that works OK then try WPA-PSK. If you have something that doesn't support WPA-PSK (it may only need a driver update) it's probably about time to replace it anyhow.

I had this "destination unreachable" while virtual machining domain computers and clients. It turned out to be something with the adapters (my case was with the domain and not client)
