Network has suddenly disappeared

I installed a wireless network in my house and have 5 computers on the network - they all worked well until a week ago.  All of a sudden a laptop cannot detect the network.

When I diagnose and repair, it asks if I want to start DHCP.  I go to services as an administrator and try to start the service, but I get an error message indicating that it cannot start because a dependent service cannot start.  All other computers on the network still work fine.

I even tried to attach a wireless USB, same problem.  Now - my son says he went to services and changed something, but I can't for the life of me what it could have changed.  Any suggestions?  I can 'reset' services are running?

Thanks in advance.

Try a system restore to a Date before all that your son has changed:

Restore point:

http://www.howtogeek.com/HOWTO/Windows-Vista/using-Windows-Vista-system-restore/

Do Safe Mode system restore, if it is impossible to do in Normal Mode.

Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

Try a restore of the system once, to choose a Restore Point prior to your problem...

Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

Read the above for a very good graph shows how backward more than 5 days in the System Restore Points by checking the correct box.

See you soon.

  • Flash has suddenly disappeared

    I using Windows 7 and the PC message at the bottom of the screen that tells me that I have to solve a problem with Flash Player.  When I click on it, it tells me that it has been removed from my computer.  I have not removed and I have no idea why he disappeared.  I did a full system scan with Norton who has not found anything and a distinct malware scan that did not detect anything either.  There is no other problems on my computer and everything works well.

    I tried to download it from the Adobe Web site and get a page that has no installation or download button.  I tried pressing enter and tab, but in vain.  I don't know how to install it without the button.  It will not allow to do me anything.  I tried searching for it on my computer and the only thing he finds is a read file me.  I'll see if it is listed in Add/Remove Programs, and if it is, completely uninstall and try that?

  • MS money has suddenly disappeared

    I realize that MS Money was drained by Microsoft.  However my 2000 MS Money Progr. has worked with my Windows 7 without problem until today.

    While the money is still listed in the control panel under "Uninstall" and in the "program files", the first page of Microsoft is covered by the notice: money cammpt locate 'C:\Users\xxxx\Docouments\back-up\My 2011 Archives account' or cannot open, perhaps because it is a read-only file. etc etc etc.

    I got windows search. * mny without him find one of my regularly do backups.  There is no trace of any help.

    Re-install the progr. did not help. In the end, the msg above appeared again.

    Is this what can I do to find my last backup?

    A DRL file is temporary should be deleted when the money is closed.

    Where are\were your data files and backup Money located? They should be in the Documents, not the default money Program Files (x 86).

    If the files are located in C:\Program Files (x 86) \Microsoft silver, copy the area of Documents are open them from there.

    If the files are not in an area, something has been deleted and them. I hope that you have a backup procedure for your data where you can find them.

  • All the presets suddenly disappeared?

    All the presets, I've had InDesign CS5 has suddenly disappeared. Print presets, the predefined settings document, everything I put in place to begin a new document as paragraph and character styles, swatch colors, etc. The only thing that is still intact is my saved workspace. I'm sure I'll have to put it all once again, but y at - it a way to save ALL these preferences so that I can just restore them if it happens again? And Yes, I have Time Machine turned on and maybe that I did something right, but nothing came back to normal with a restore since last week when I know everything worked very well. Thanks in advance!

    InDesign CS5 V7.0.3 on a Mac

    Dpocment and printer presets are saved in the InDesign Defaults file (it's a real file name, not a location). See replace your preferences for more information on find and save the preferences or look in tools Blatner (plugin) or in-Tools preferences Manager (I think).

  • All the pdf I downloaded on my desktop (Windows 7) suddenly "disappeared" and I can open and view, but cannot remove them or move them to another file.  When I try to delete, I get a messge saying my trial has expired and he wants me to have

    All of the pdf files I've downloaded on my desktop (Windows 7) suddenly "disappeared."  I can open and view them, but cannot remove them or move them to another file.  When I try to delete, I get a message saying my trial has expired and he wants me to buy which I can't do because I don't have a serial number to put in. What happened to the "free" Adobe Reader I thought I had?  How can I get these PDF files to become mobile?

    You (or someone) downloaded the free demo of Acrobat Pro, a little more than a month. If you use this software $20 / free months instead of drive for a month. If you don't want to buy it, now you must uninstall it and go back to the use of Acrobat Reader.

  • My bookmark 'COMPUTER' suddenly disappeared, HELP!

    Only the "COMPUTER folder/bookmark is missing from my bookmarks bar. Every other bookmark from the toolbar is stable, as the toolbar itself. I know how to restore the Favorites, as I backup frequently. However, in the restoration, I won't lose a good number of changes, moves and respective additions of others bookmarks and their marked envelopes of a bookmark.

    Therefore, using restore itself and is, of course, a last resort, but there should be and long ago there was a now forgotten, way to go towards a 'library' restore only lack Toolbar/folder, without having to use the backup restore.

    Knows the option above to anyone? Finally, can anyone suggest why this exact situation has occurred under my administration a few more times? What could I do to cause this sudden disappearance while I'm working in the missing bookmark (that I forgot to mention earlier). Something may be corrupt? I need some "with it" ammunition for future episodes! These events are really traumatic for me... No. a joke!

    Thanks in advance. Windows 7, Firefox browser Google 25.0.1,

  • Hotmail has suddenly changed appearance and now present on the top of the page blue with lines. I have a screenshot...

    Run Firefox 15.0. Hotmail has suddenly changed appearance and my page is not at the bottom of the screen. The top 5/6 of the page is a series of horizontal blue stripes. Text in the blue section is the Windows Live titles such as ' home, Mobile devices, etc. When I try to compose a new message, text in the blue box partially covers the 'To' button, so I need to position the slider at the bottom of the button to enter an address. I have tried Hotmail in IE and it seems fine, so it must be a problem of compatibility between Hotmail & Firefox. Hotmail has not responded to my questions by e-mail. I could understand that if this happened at the beginning of a session, just after I have lights, but this happened after, I had been active in Hotmail and other sites. Other sites are not affected, just Hotmail and only in Firefox.
