wireless won't stay connected

and it's driving me bonkers.

ok, so i have windows 7 64-bit on an acer aspire 5750 laptop. i am not sure what our router is, i just know we have cable one internet...i'd have to search and possibly ask my aunt what it is.

anyway. for several months now, my wireless will work very intermittently. it will stay connected for a little while--occasionally, it will work for 10+ hours before dying, lately (and what has been driving me most insane), it will work for 15-30 minutes, possibly more than an hour, but not more than several hours. it all works very randomly.

it first goes to say that there are connections available and then goes to the red X. repairing the connection works occasionally. other times, it will say that there is a router issue (when there isn't/shouldn't be), or it will say troubleshooting can't identify the problem. disabling and then enabling the wireless connection has no effect. when that happens, i have to either put it to sleep (which has worked most of the time) and the connection will come back, but now lately, i have to shut the computer down and turn it back on for the wireless to actually come back. right now, i'm on the wired connection, which works perfectly fine.

i don't know if this is connected to it at all, but i thought i would mention that if i have headphones plugged into the headphone jack on the left side, i can't put pressure on the left side below the keyboard at all or the effect is like i don't have headphones in. i'm thinking something's gone wrong internally? but i don't know if that has any effect on the wireless or where the wireless card even is, to be honest. it's under 2-year warranty and not even a year has gone by, so if it's got actual physical problems, i can send it in, but i'm wondering if there's anything i can do to fix the wireless.

thank you! :)

would you post the following tests when its working OK and then repeat ALL the tests when it disconnects

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

------------------------------------------------------------------------
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}> 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

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

lets see an xirrus screen shot



------------------------------------------------------------------------
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.co...-Inspector.aspx
Direct link to the program is here http://wpc.475a.edge...Setup.1.2.0.exe

{If the above link does not work heres another link http://www.pcworld.c.../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.co...guide1-2-0.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.


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/
