Recently I have run into some weird behavior on my tr - i believe caused by an antivirus program that was expiring and kept trying to logon (when no connection available) and hanging up the system.  :x I then uninstalled the antivirus program (btw, it was Panda antivirus) which caused serious hangups on my computer (error messages in spanish about extensions not available) and wouldn’t shutdown properly. 

After some hard shutdowns, I lost all restore points (permanently it appears), and the device manager showed only the flashlight searching for devices!  After several startups through msconfig, shutting down the remnants of the antivirus items in the Startup folder in msconfig, and finally removing all of the antivirus program, it seems most of the programs and devices are working now.  But sadly the wireless connection is not working. :( 

When I try to View Available Wireless Networks, I get only a greyed-out box - the only available action is to click Cancel.  I cannot go to Advanced or Connect.  I am guessing that some settings got changed.

In Device Manager, it shows that the wireless card is working properly.  And the driver is the most current one.

I have also looked in Wireless Network Connection Properties, but I can’t tell what I need to do there.  The only thing I noticed is that under the “This connection uses the following items”, all 4 boxes are checked, but the Internet Protocol item has Install highlighted and Uninstall greyed-out.  Is this a problem?

Any help is greatly appreciated.  I am always impressed by how many techie gurus are on this forum.  Don’t fail me now!

make sure your router is broadcasting the network. use ping to check the connection to the router. see if it works at other wireless networks(ie library,starbucks) or it doesn’t work everywhere.

I have tried your suggestions, except for pinging the router.  How do I go about doing that?  I have other computers on my wireless network, and they are all fine.  Prior to this problem, the sony had no problem connecting to the router.

I still suspect that some setting has been thrown off.  Is there some tcp/ip protocol that needs to be re-established?  I am just guessing here, but I feel that I need to reset something - probably something simple - but I don’t know what.  Question:  Internet Protocol Properties, do I need to fill in IP address and DNS server address fields?  These are blank, and I believe they may have had addresses before.

Any suggestions?  Help much appreciated.

to pin: start->programs->accessories->command prompt-> C:\ping address of your router. (ie. C:\ping 192.168.1.1)

you shouldn’t need to fill in the IP and DNS address. just make sure the auto detect settings boxes are checked.

how about remove TCP/IP and everyother things about networking and reinstall all those; some of those files might get damage. but first try to use ping command like kimballa said.

Thanks for the responses.  However, I am not having any success using the Command Prompt.

Question:  When I get the Command Prompt, it shows “C:\Documents and Settings/My Name”, and when I type in C:\ping 192.186.1.1 (btw I have a Linksys router), it says “C:\ping is not recognized as an internal or external command ...”.

This may sound dumb, but how can I get a clean line to type in the ping command?  Also, am I missing a character or space?

Thanks for

While I wait for an answer on how to use the command prompt, I want to post another piece of info on my wireless connection.

When I click to Properties on my Wireless Network Connection in Network Connections, I don’t get the Zero Config dialog box I am used to.  In other words, I do not get the Wireless Networks tab next to the General tab.  All I get is a tab called Advanced, that has 2 areas for Internet Firewall, and Internet Connection Sharing.

So, it appears that I am not able to get to the Windows Zero Configuration utility.

Any thoughts on how to get this to start up and work?

i have a linksys router as well. it sounds like you are not connecting to your router. it shouldn’t matter where or not you get a clean line but here’s the command to type to get to c:\ . Type “c:\” in the command prompt… easy huh.
try connecting to your router via cat5 cable…to kinda isolate the problem.

Well, 2 things, but first thank you for the help so far:

I finally pinged the router and it was unsuccessful - 4 packets sent; 0 successful.

Also, I connected via ethernet cable and got instant connection.  So we know that works.

So, now what??

Also, looking again at my Wireless Internet Connection properties, it looks like it thinks its part of a network, rather than a simple internet connection.  The Properties box has the boxes for Microsft Client, Printer and File Sharing, TCP/IP Protocol.  I just want the Zero Config box (gone) and the Wireless Networks tab (gone).

Next steps?
Thanks for the help so far linc.

np :D
well..at least we know that the router works.
what about QoS packet scheduler? not exactly sure what it does but i have that box on my properties.
try http://192.168.1.1 and make sure all the settings are good and the router is broadcasting the network..just to make sure.

I have QoS packet scheduler on mine too.
I have checked the router settings and all is fine.

I have the wireless network icon in the lower right-hand tray.  The problem continues to be that when I go to View Available Networks, the entire dialog box is greyed-out -  nonfunctional.  Normally, the dialog box allows me to click Advanced and see Available Networks and Preferred Networks.  I can’t go there because the Available Wireless Networks dialog box pops up but is nonfunctional.

hmm…i would just do a recovery but thats just me. hope you made some backups of settings and files. i a backup plan similar to gr00vy0ne where system/program data are seperate into different drives. that way whenever my tr acts up, i just restore just the drive with the system/programs. sorry couldn’t help you out. for me i have to have the computer in front of me for me to keep troubleshooting and keep track of the changes and progress being made. hopefully somone here can help you out.. :oops:

check this out..perhaps it will helps
