I have a Windows Lenovo laptop; Windows 7. I recently started downloading torrents (television series) and probably because of its excessive use the wireless between my laptop and my router has been a bit laggy and it wasn't able to reach my laptop all the way to my bedroom like it used too. So I kept it close to it and worked fine. However after I got from celebrating new years; in the morning in the room near the router the laptop and wireless failed to connect. I entered an extension cord into my laptop from the router and the internet connects. However the wireless does no longer work. The wireless works with iPods and other computers but not for mine. I'm worried I may have ruined it and I'm clueless as what to do now? Please somebody help me out... be much appreciated :confused:

you most likely have a virus by using torrents especially if you have been downloading illegal copyright material- most virus/malware comes from torrents

with out the cable connected and if you connect to the wireless -
in the morning in the room near the router the laptop and wireless failed to connect
what error message do you get

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

Check the wireless is switched ON
theres often a physical switch or a combination of the FN and one of the F keys to toggle the wireless on/off - is the wireless on?
------------------------------------------------------------------------

lets see an ipconfig /all and xirrus screen shot

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

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

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) 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

would you do the following three ping tests - see below - Without the cable connected , as you are showing a wireless connction in that ipconfig .all

then after posting the ping tests would you then connect with a cable - so that the internet is working and post another ipconfig /all from a cable connected - when working

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

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 172.20.10.1
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.

you will not get a robust connection on that signal @ -83
you need at least -70 (note the negative) to get a robust signal

so you will need to make some changes to the position of the router - or router aerial , or the PC location and/or adapter and/or aerial

just moving the router a few feet can make a lot of difference or if it has an eternal aerial turning by 90degrees

you could try changing the wireless channel on the router to use channel 11

has the signal changed recently - anything changed in the location, new furniture - it may also be a sign of an issue with the router if its quite old

I've attempted connecting the internet with the laptop right next to it in-fact with excellent connectivity and unable still to connect. I've only downloaded three TV seasons and won't be doing so again; any solutions to torrents ruining internet connection perhaps. Sorry for all the fuss and thankyou for you help

lets see an xirrus from that PC

also see my post #4 - and provide tests as requested

any solutions to torrents ruining internet connection perhaps
it should not be torrents - but any virus/malware picked up as a result of using torrents - its one of the most common form of virus/malware transfer


so you have two devices that will not connect by wireless - and both work with cable connections -

so as not to get confused
on the PC we discussed and you showed the results for so far
can you follow my post #4 and provide the ping tests
