Wireless keeps saying "No internet access"
Out of no where today, my wireless connection has begun saying "No internet access" and I can't go anywhere online Ever since it began happening, it's been saying that for longer amounts of time. So at first it was only a few seconds, now it's been taking a minute until I re-gain internet access. I haven't installed anything or ran any executables lately, don't have any viruses, I obtain my DNS and IP addresses automatically, and a few minutes ago I installed the newest firmware update of my router and I'm still losing internet. I have a NetGear WNDR3400 router if that helps.

Have you update the driver for your adapter
is this just one machne that is having the issue or are others also having the same problem

when its working lets see the following ipconfig/all , ping tests and xirrus
then when it disconnects repeat ALL the tests and post here


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

------------------------------------------------------------------------
{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_d...d_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.

After updating a router's firmware it's best to reset it to factory defaults and reconfigure.

@etaf, I tried updating my adapter driver but Windows says I currently have the "best" driver software so there are no updates. The "No internet access" is happening for everyone connected.

well those figures say toy have a wireless connection and can access the interent

no need to black out the SSID - its of no value to anyone

The "No internet access" is happening for everyone connected.
I think we need some more info

Everyone - so how many PCs and is that wireless and cable ?

Where the results in your POST when it was disconnected

lets see the same tests from another PC when disconnected - to see if the same as your results

The signal strength is marginal, at best. Not surprising if the connection is experiencing difficulties simply because of that.

Me and my brother are both using laptops with built-in adapters that connect wirelessly, and then there's the desktop PC sitting there connected to the modem and router by cable.

By the way, when it was giving me that message of not having internet access, I did ipconfig /all and it was the same result, and when I pinged any websites, it would say "Request timed out"

where is the router ? - try moving the location slightly can make a lot of difference , or if it has adjustable aerials - move them around
I have also found changing the wireless channel on the router can help - so try channel 6 and channel 11 and see which is better if any

post an xirrus screen shot - see if you can get a stronger signal

Well, you see I can't really move it. I don't have any long ethernet cables. I've only got a (maybe) 2 foot ethernet cable that came with the router. I haven't tried changing channels, so maybe that will help.

channels may - BUT even moving 6" can make a difference -i had a router that was on a shelf on a PC stand and moving just a few inches to the top of the monitor - made all the difference to the upper floor of the house

Hmmm, changed channel to 6, seemed kinda laggy, changed it to 11, and 11 was also laggy and after a few minutes got booted from my wireless and was unable to connect for another minute, then it reconnected. Now I'm still getting the "No internet access" message. I'll see what moving it will do

Aha! I found a really long ethernet cable of mine which I thought was broken, and then I replaced the short cable with the long one, and then I moved the router up onto the first shelf of the desk, and am still on channel 11 and things are A-Okay so far.
EDIT: Nevermind, it's still saying "No internet access" repeatedly
