DSL problems

All,

Moved to a new location, setup with DSL. Using a D-LINK wireless modem/ADSL router. MODEL#DSL-2640B.

One blue ray player connected directly to router, my comp connected with Netgear Wireless-N adapter, wife's Mac connected wirelessly. Setup with WPA2-PSK. The internet has been working fine for a few days when the problem started.

What I know so far is my comp disconnected and reacquired the router late at night. My wifes mac cannot connect at all (I know the password by heart but the comp keeps saying it cannot connect). Her Mac is about twenty feet away from the router, same level house. It will find the network fine but will not connect after multiple attempts to restart both the comp and router.

The Blu ray player today started to say it couldn't connect to netflix and was unable to download updates. Reset of the router resolved that issue but who knows how long it will last.

Anything I could track down or any problems I need to look for?

as this is happening on both wired and wireless connections, i would suggest its the router or the ISP issue
when it happens whats the status of all the lights on the router

you have carried out a reset of the router now - so lets see the following information when its working fine and then again when it resets



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

Start> Run {search bar in Vista}> 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

these tests will check various stages of the connection
the first ping test
ping 192.168.0.1
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

http://www.xirrus.co...y/wifitools.php
Direct link to the program is here http://www.xirrus.co...ad_redirect.php
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

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/

I see the link for how to run this test on her Mac, but how would you run the ping tests and ipconfig all from a Mac? Does this need to be done from the blu-ray player as well?

Update ETAF,

My wife's mac is finding the network just fine. But when you go to join it it asks for the passkey. I enter in the password (I know this one by heart) and it will go right back to the screen that asks you to enter the passkey. This is what her computer has started doing, when the internet was working. It would then say she needed to join the network and then would work for a bit.

Any thoughts?

Second Update:
I changed the passkey and her computer connected right away and has no problems. Will this become an issue again?

I have had similar issues with this exact model D-Link before. From memory there was a firmware update available that fixed it.

Do you remember what the update version was? I purchased this one only two weeks ago and the version (as far as I can tell) is GE_DSL-2640B_3-06-04-1G00.A2pB021c.d19b which I take to be 306041. That is listed as the most current update version on D-Link's website.

Edit: right back to where I started, changed the passkey and the Mac connected fine for about one hour. Then the network dropped off and I'm back to it continuously asking for the passkey.

After searching the forums for the Mac problem I have come across replies from the apple forums that detail others having the same connection issues with their various Mac products and wireless networks. It doesn't seem limited to D-link products, I saw Cisco and Netgear in there as well.

I guess our only option is to connect the Mac directly to the router itself. Anyone have further suggestions or info for this problem?

Wait my mistake, the issue I had was with the 2740B. As long as your firmware is the latest then you will (usually) have the best chance of a stable connection.

Also it could be more related to the wireless card in the Mac rather than the modem. When it happens next, just try power cycling the modem (power cord out for 10 seconds then back in and let it start up again).
