Wireless network, the dreaded yellow triangle
I can find and connect to the wireless network in our house, but it has the yellow triangle with an exclamation mark. My housemates are on the internet fine on their laptops and my xbox live is working, so it's clearly an issue with my laptop. My laptop's internet evidently works with an ethernet cable too, but I can't just go through an ethernet cable all the time since the router is in a housemate's bedroom.

Checklist of things I've tried so far:

- Turning the router off and on

- Turning laptop off and on

- Allowed my laptop to 'forget' the network and re-enter password etc to no avail

- Looked on the router homepage for any blocking of my laptop, all seemed fine

- Gone into 'cmd' and typed ipconfig/release then ipconfig/renew

- System Restore

- Tried updating my drivers through Control Panel but it reckons my Wireless Network drivers are up to date

This is a mystery, hopefully somebody can help.

Thanks in advance.

Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector. Also show for an attempted connection ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Thanks for getting back to me, sorry I didn't see it until now! Here is a screenshot of the program's network page.

The top network is mine.



And the paste of ipconfig /all:

I doubt it's important, but just to clarify, the internet is working with an ethernet cable, is working wirelessly for my housemates' laptops and when I try to connect wireleslly, the connected sign comes up for about 10 seconds and then the yellow triangle appears.

Thanks in advance for getting back to me.

Thats important to know
cna we see an ipconfig /all with the PC connected and working by ethernet cable - interested in the DNS

what firewall do you have - norton, mcafee etc
it maybe blocking access on wireless ...

alos try a tcp/ip reset - see below

is kimberly road the wireless you are trying to connect to ?
if so try removing the wireless profile and reconnect and make sure you are using the correct key

Wireless Profiles
http://mgmcc.forumotion.net/networki...ofile-t109.htm
- Vista/Windows7:
http://www.tp-link.com/support/showfaq.asp?id=214
- delete the wireless profiles
Start> control Panel> classic view> network and sharing center> manage wireless networks

Delete the profiles
you will then have to enter the wireless security key for any networks you connect to

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

TCP/IP stack repair options for use with Vista/Windows 7.

Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

If you receive the message
[b]The requested operation requires elevation.[b]

I've recently done a system restore to factory settings to try and eliminate the problem but it was still occurring, which means I only have Windows Firewall currently, and I tried disabling it to see if it made a difference, which it didn't.

Before the restore to factory settings I deleted the wireless from my laptop's memory so that I had to re-enter the password again and it still didn't work. I've been on the router configuration page to check if there was anything blocking me and there wasn't, and the password was correct.


I did all the cmd resets you wanted me too; for the winsock catalog reset it said successful and to restart, same for the ipv4, and the ipv6 said there was no user settings to reset or something along those lines.

Restarted, still a yellow triangle.

What did you want me to post here after, another ipconfig /all? Here it is in case that's what you wanted:

I don't understand what you mean?

I'm not too tech-smart, all I know is that I'm trying to connect to the wireless internet. How would I find out which one it is, if it's a wrong one etc?

cna you log into the router and remove the WPA wireless encryption - disable so that you have no encryption - then see if you can connect
if so put the security back on and see if you connect again

Did what you said but still got the connected but with yellow triangle thing.

When I took away the password it said I was connected to 'kimberly road 2' when I connected to the insecure kimberly road network.

I tried to connect wirelessly but it came up as connected for about 10 seconds then the yellow triangle popped up.

next would be to change channel - lots on 11 - so try channel 1
also turn off the wide 40mhz range off and just use the 20mhz

leave wireless un-secure for the moment -

then do a power cycle - turn everything OFF
turn on the modem if you have one - allow to settle
turn on router allow to settle
turn on PC and try and connect

if that does not work lets see all the services running

------------------------------------------------------------------------
{Services}
post back the status - started/stopped and automatic/manual
Check your Services are Started on all PCs:
  • COM+ Event System (for WZC issues)
  • Computer Browser
  • DHCP Client
  • DNS Client
  • Network Connections
  • Network Location Awareness
  • Remote Procedure Call (RPC)
  • Server
  • TCP/IP Netbios helper
  • Wireless Zero Configuration (XP wireless configurations only)
  • WLAN AutoConfig (Vista wireless configurations only)
  • Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic (or perhaps manual).

If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running.

Checking the event log is also a good idea here, there may be clues to what is failing.
Start > control panel > administrative tools > event Viewer
