Hey all!

Ok. So I've been having this problem for about 2wks now. I've tried to fix it myself & thought I did, but I still get this error message, "cannot communicate with primary dns server 209.18.47.61". It's amazing how I'm on right now considering I get dced almost on a daily basis, w/ most days being for hours. I'm on a wired connection right now, but even then i get the same message. Usually when I'm on it's fine but last night and earlier today I just kept constantly getting dced over and over again.

I'd really like to know how to permanently fix this problem cause it's quite annoying to deal w/every single day. ^_^


I'm pretty sure your gonna want my ipconfig info so here it is:

would you post the ipconfig /all again when it disconnects (save in notepad and then post when you get the internet back again)
also - post all the ping tests below when its working and then repeat when it fails

------------------------------------------------------------------------
{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

Start> Run {search bar in Vista}> CMD to open a DOS window and type:

Type the following command
Ping 192.168.1.1
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

OK so you have lost the ip from the router

can you connect to the router with cable and see if it then disconnects

anything else connected by wireless and still working all OK

also 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

http://www.xirrus.com/library/wifitools.php
Direct link to the program is here http://www.xirrus.com/library/wifi_download_redirect.php
Then run and install the program
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

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.

i would log into the router and change the wireless to use channel 1 - you have another strong signal on channel 6

make and model of the router ?

you probably need to use
192.168.1.1
in an internet explorer address bar
that should open the router login screen
now depending on make and model of router - you may need to use admin in both username and password - but sometimes just in one field depends on make and model

then goto the wireless section and change the wireless channel to use 1

what about the connection with cable ??

se if it disconnects again with channel 1 - it may take longer but if we do one thing at a time then at least you know what fixed it

so the next things i would do
Update the Network adapter on the PC - should be available from the support site of the PC manufacturers webpage
Remove the security on wireless and see if that makes a difference

You have another stron signal on channel 6 - look at the xirrus - it shows all the signals broadcast and colour codes them green/yellow/red

you can see two green signals both on channel 6 - so likely to interfere hence the suggestion to change to 1
