Laptop Suddenly Won't Recognize Network

Greetings and thanks for any help forthcoming. My husband pastors a church and in our office, we have 2 desktops hardwired together, sharing the internet connection. We also have 4 laptops connected via the router. Three of the laptops are fine, but the other, a Toshiba Tecra S1, stopped recognizing the network yesterday. It has always worked before, but suddenly, the only network it finds is named "Setup". I've never seen 'Setup' as a network before. When I double click the network icon on the taskbar, that's the only thing showing up. When I go to the window to choose a network to log on to, that's still the only thing there - 'Setup' network. The network troubleshooter says it can't find the problem.

I ran Windows' System Restore first thing and though it said it successfully restored the computer to another time, the problem remains. So I tried another restore date with the same result.

Not knowing much about networking except how to get it going, I haven't tried anything else and thought I'd get some help.
Anyone have any ideas I could try?

Thanks!

Yeah, there is something wrong there.

Can you check, if you can connect while hardwired with ethernet cable?
Do you have any errors in Device Manager, especially regarding wireless network adapter?

Tried hardwiring it to the modem but it still couldn't connect. Checked the Device Manager and there are no alerts for any of the hardware.

Thanks again,

Try some basic steps....

Make sure, your computer is set to obtain IP address automatically.
1. Go Start>Settings>Control Panel (Vista/7 users: Start>Control Panel)
2. Double click Network Connections (Vista/7 users: Network and Sharing Center)
3. Vista/7 users - From the list of tasks on the left, click Manage network connections.
4. For a wired network connection, right-click Local Area Connection, and then select Properties.
For a wireless network connection, right-click Wireless Network Connection, and then select Properties.
5. From the General tab (Vista/7 users: Networking tab), click Internet Protocol (TCP/IP), make sure it is checked, and then click Properties
6. Click Obtain an IP Address Automatically, and then click OK.

If that doesn't work...
Turn off computer. Disconnect router, and modem from power source for 1 minute. At the same time disconnect ethernet cable as well.
Reconnect everything.
Restart computer.

If that doesn't work, bypass router, and connect computer straight to the modem.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista and 7, while holding CTRL, and SHIFT, press Enter).

In Command Prompt window, type in following commands, and hit Enter after each one:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
net stop "dns client"
net start "dns client"


Restart computer.

If that doesn't work...
Go Start>Run (Start search in Vista and 7), type in:
cmd
Click OK (in Vista, while holding CTRL, and SHIFT, press Enter).

At Command Prompt, type in:
netsh int ip reset reset.log
Hit Enter.
Type in:
netsh winsock reset catalog
Hit Enter.

Restart computer.


If that doesn't work...
Download, install, and run WinSockFix: http://www.softpedia.com/get/Tweak/Network-Tweak/WinSockFix.shtml (doesn't work in Vista and 7)
Restart computer, and check again.

If that doesn't work...
Download Dial-A-Fix (DAF) (doesn't work in Vista and 7):
http://wiki.lunarsoft.net/wiki/Dial-a-fix#Mirrors.2Fdownload_locations.2C_and_articles

Have XP CD available in case DAF needs a file. Likely not!

Check all boxes on the screen (clear any restrictions if it shows any)
Then click GO!

When the entire page is finished click the HammerHead at bottom to go to the second DAF page.

Here, one at a time, do the below:

Reinstall BITS
Reinstall Windows Firewall
Repair Permissions
Reset networking

Watch for any File not found or other errors and make note as this may lead to the fix!

Restart computer.

Hello again. Had to leave my office yesterday before I got all your last instructions done. Came in today intending to finish and TODAY, another of my laptops won't connect! It says the 'adapter is not connected'. Impossible. Nothing changed since yesterday.

Have no idea what might have disconnected the adapter and no idea how to reconnect a laptop network adapter if it is disconnected. It is a 3 month old HP G72 with Windows 7 and it's never failed to connect before. Odd that one would act up then a couple of days later, another one. Though the syptoms are different. The newer one doesn't have 'Setup' as a network to connect to, just says none available. Then the troubleshooter says the adapter isn't connected.

Anyway, I'm going to try running through your complete list of instructions today on the first laptop that went down. Also, neither of them came with Windows CDs, so if DAF needs the XP CD for that laptop, I don't have it. I have an XP CD here, but it's not the one licensed to that computer. Do you still want me to try DAF?

It looks as if it will be busy here today, but I'll check back when I can to see if you have any ideas about the second laptop or further instructions on the first.

Thanks so very much for your help!
S.

Hi, Broni;

Today I've done all the steps you sent except for the one that might require the XP CD and since the laptop didn't come with one I didn't know if I should try that. What do you think? Nothing I've done so far has changed anything. It still says no networks are available and when you go to "View Available Networks" the only 'network' that shows up is "Setup - an unsecured computer to computer network" - which of course, the computer won't connect to.

Also, I tried twice to run system restore on the new laptop that won't connect and System Restore won't complete. It says, "System Restore did not complete successfully. System Restore failed while deleting the following directory: Path:C:\Windows\SysWOW64\servicescache.exe An unexpected error occurred during System Restore(0xc0003005)."

So far, the other two laptops (we have a total of four) are still connecting with no problems.

What do we do next? I really, really appreciate your help. Thanks so much!
S.

OK, on the new HP, I've run the System Restore utility from Safe Mode. It still didn't work - got the same exact error message as before. However, I discovered my wireless device switch had been accidentally turned off! Turned it on and PRESTO, connected! BUT, why oh why won't System Restore run? Isn't that bad?

Did you still want me to run DAF on the Toshiba, even though I don't have an XP CD for that computer? Sure wish it was as easy to fix it as it was the HP!

Isn't it weird how things can be working perfectly when you shut down one night and when you boot up next day, things have gone ka-pooey? Computers sure are strange creatures!

Appreciate your help!
S.

OK, that took a while. But unfortunately, it didn't change anything.

Here are the error messages:

Error 127 came up 8 times. It said C:\WINDOWS\system32\filenamehere.dll is not registerable or the file is corrupted. Your version of filenamehere.dll is versionnumberhere. Please contact dial-a-fix@DjLizard.net so that an exception can be made for your version of this file.

The 8 files were: setup.dll; imgutil.dll; inseng.dll; mshtml.dll; msrating.dll; occache.dll; pngfilt.dll; and webcheck.dll

5 of those files also had this error message: C:\WINDOWS\system32\filenamehere.dll is not DLLinstallable or the file is corrupted. Your version of filenamehere.dll is versionnumberhere. Please contact dial-a-fix@DjLizard.net so that an exception can be made for your version of this file.

The 5 were: setup.dll; inseng.dll; mshtml.dll; occache.dll; and webcheck.dll.

Those were the only error messages.

Isn't it odd that System Restore, which said it did complete successfully on the Toshiba, didn't fix this problem since the network connection had been working at the time of all the previous restore points? I thought Restore put everything back as it was at the time the restore point was made.

Thanks again!
S.

Go Start>Run ("Start Search" in Vista/7), type in:
sfc /scannow
Click OK (hold CTRL, and SHIFT, hit Enter in Vista/7).
Have Windows CD/DVD handy (with Vista/7, most likely, you won't need it).
If System File Checker (sfc) will find any errors, it may ask you for the CD/DVD (rarely in Vista/7 case).

I realize, you don't have Windows CD, but run the scan anyway and see, if it'll find any files, which have to be replaced.

The scan had barely started before it started asking for the CD. It has already asked over a dozen times. It says, "Files that are required for Windows to run properly must be copied to the DLL Cache."

Why, oh why don't these computer manufacturers put operating system disks in with the computers they sell anymore??!!??

S.

OK, it's asking repeatedly, almost as soon as I cancel one request, it asks again. So far, there are dozens of dll files needing to be copied to the DLL Cache. It doesn't say which .dll files they are, though. The scan is about 1/8 of the way through the progress bar.
