Remove the wireless security
Is your wireless security enabled?
if so - log into the router and remove the wireless security - now see if it will connect.
if it does - log back into the router and try with the wireless security enabled again
Hi guys, I have the following symptoms with a TP-LINK router (TL-WDR3600) connected to a modem-router.

- Wired internet works fine
- Wifi signal ok, but not as stable as it should be
- NO internet via wifi, unless I remove the wifi security
- Removing and restoring the wifi security gave me back internet access, for only a while though.

All tested with pc, tablet and phone.
Any clues to what might be the problem?

user guide here - if we need to refer
http://www.tp-link.com/Resources/document/TL-WDR3600_V1_user_guide.pdf

go through the wireless settings on the router configuration pages Page 32 - and post back as much info as possible on how you have it setup -

- Wifi signal ok, but not as stable as it should be
what does this mean exactly

All tested with pc, tablet and phone.
none of these connect via wifi - but PC works on cable connection

- NO internet via wifi, unless I remove the wifi security
- Removing and restoring the wifi security gave me back internet access, for only a while though.
exactly what do you mean for a while ?

lets see an ipconfig /all and xirrus screen shot from the laptop
------------------------------------------------------------------------
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.

If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

We would like to see the results from an ipconfig /all - post back the results in a reply here.

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.

This should work for all windows version, XP, Vista, W7
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)


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

To post a screen shot of the active window.
Windows XP
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.

Vista or Windows 7
you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

Windows 8
you can use the snipping tool > Open Snipping Tool (From the Windows 8 Start Screen, type "snip" and press enter.
>Press the Esc. key.
>go back to your Windows 8 start screen - Swipe from left or press Window Button
>Press Ctrl+PrntScr button to use Snipping Tool

I've done an upgrade of the firmware, it appear it is a common problem for the tp-link wdr3600 router. Will come back in a day or two to confirm is that was the real solution. Thx for help!
