Can't connect using wireless: problem with 6TO4 adapter
I can't connect to the internet using our wireless router. The signal is excellent but there's a yellow triangle with an exclamation point. It says that there is limited access. I tried resetting the router, checked all the plugs, restarted my laptop., all to no avail. I tried connecting using my phone, and I can go online so the problem lies with my laptop.

I checked my device manager and under Networks, the 6TO4 adapters has a yellow triangle with exclamation point. With a code 10 error. I tried to run 'check for solutions" but I can't connect to the internet. Using my phone, I saw websites dealing with the same problem. I uninstalled all the 6TO4 adapters along with the isatap adapter because it also has the same problem except that it's reporting error 31. Then I restarted my laptop.

I can connect to the internet but only through LAN. I still can't connect through my wifi. I tried to reinstall the 6TO4 and isatap but it still shows the same message.

I'm not the only person who uses the internet in our house. My siblings also have the same problem with their own laptops.

Can anyone help me. How can I connect using wireless connection?

do any of the machines have mcafee security suite on - there has been an issue recently with an update

otherwise - you have PCs that will not connect to the wireless - but phones connect all ok

can you reply with all the devices that will not connect to the wireless and a list of those that do

try a full powercycle


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

How to power cycle

“power cycle” process to reboot or reset the modem/router
  • Switch off all the devices modem, router and computers also unplug their power cables.
  • Wait at least 1 to 5 minutes,
  • Plug the power cords back in, but don’t switch them on.
  • First turn on the modem and then wait for a few minutes for it to settle and all the lights to become stable.
  • Next switch on the router (if a seperate device) and then wait for a few minutes for it to settle and all the lights to become stable.
  • Now turn on your computer, You should now be able to access the Internet.

I tried what you suggested but it still didn't work. The power cycle.

Oh, I also tried the system restore in case an update was what started it. But the problem started last Sunday (August 19) and the last update was last August 16. So the updates couldn't be the culprit. But I tried it anyway and restored my system to how it was before (August 14 restore). Didn't work at all.

The laptops are not connecting wirelessly (but I can connect online through the cable)::
>HP Pavilion dv4 Notebook PC. It has Vista Home Premium service pack 2
>Acer Aspire. Its using windows 7 ultimate service pack 1

I can connect wirelessly using my phone (Nokia E63) and through my ipod touch. My sister can also connect through her Samsung phone

Any help?

Hi guys,


We've been getting calls about this all day at Plusnet, I noticed you might need some help fixing this, I found out a few tips today.


Firstly can you ping the router, if it fails, your most likely affected by the Windows update, also the "unidentied network" is a noticeable symptom.

If you can ping the router, Gratz! all you need to do it go to your start menu > control panel > depending on Os windows 7 is programs and features, Xp add and remove programs. Once in here select Mcafee, you can right click it and press uninstall. Restart computer, jobs a good'en we're back online, just reinstall should work fine (I have only seen it once in the past couple of days when a customer could ping router but was a windows update issue).


Ok if you can't ping the router, oh dear, if you do ipconfig as well it will most likely not give you a default gatesway or ipv4 address. First step is to disable and renable the network adaptor in your "change adaptor settings" for 7, Vista is set to "manage network adpators" in network and sharing centre. If you have XP you might have connect to in your start ment, click on that and go on network connections, This will also be located in your control panel, one in here, right click your connection, like Ethernet local area connect, or wireless network connection 2 etc.


Alot of my fellow tech guys were just suggesting system restore, but I wanted to find out the actual KB number, and after a lot of kind customers let me exploye there computer on what the issues could be. Plus i had one call were a customer had no restore points due to not having it set, so in case you don't have any restore points (even after ticking show more restore points), we'll have to remove each Microsoft windows update, after pressing uninstall an update or windows component down the left hand side or programs or add and remove programs. Ignore the other updates when the list loads, the section we care about is the Microsoft Windows, organise these in date by clicking installed-on, and remove any there up untill the 16/08/12.


If you see a Kb number ending with either 500, 209, 073 remove them, as they seem to be the main culprits.


I hope this helps, and I hope you all the best of luck, if I find anything else out i'll let you know

If the advice from Plusnettechlad still does not resolve the issue
lets see an ipconfig /all - see how below
then a
try a tcp/ip stack repair - and also post a xirrus screen shot

sometime the wireless will work in safe mode (not always) so if this works then we know its a startup program/process thats causing the issue
- try safemode with networking
as the PC starts keep tapping F8 - a menu appears - choose
safemode with networking - see if that works
------------------------------------------------------------------------

------------------------------------------------------------------------
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.

We would like to see the results from an 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 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/fil.../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.

Run the program

A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus...-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)

To post a screen shot of the active window.
1) 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.
OR
2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
Full details are available here http://library.techguy.org/wiki/TSG_...g_a_Screenshot

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

If you are using the Mac OS then use http://www.istumbler.net/ or
if you want to optimise base station position and signal strength / dead spots use
http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

the LAN connection looks more like a ISP IP rather than a router IP

if you goto
http://www.whatsmyip.org/
do you get the same IP as shown here

And your last post used a different public IP address from your previous posts.

Please describe your entire network including the brand and model of each modem, router, switch, etc., and how they and the computers are connected.
