Very disconcerting issue that happened with my WRT54G

Does anyone know what would cause my router (WRT54G) to reset to the factory settings, just out of the blue?  I have not touched the reset all button.  In fact, I was on my laptop in another room when it happened.  I lost wireless connectivity troubleshooting, I discovered that all my settings have been reset.  Even the password to access the interface on the router reset to factory default.  I was able to fix everything, but I would like to know what caused it.

At first, I thought I can have been hacked, but I have a very strong expression set with WPA2-PSK encryption key.  I also have enabled MAC filtering and only allow access to the PCs that I listed in the MAC filter list.  Fireware is also updated.

I know it is still impossible to hack, but I don't see anyone with the kind of knowledge to beat these security features want to hack my network.

Are there other reasonable explanations of why this happened?

EDIT (I forgot to add 2 things):

1. There was a power outage here earlier in the day, but I had connectivity in less than an hour after she came on, no problem.

2. just before that happened, I started having "a duplicate IP address has Ben detected on the network.  It was really strange, because the router distributes the IP via DHCP.  Why he would give one already in use?

This is probably because of the blackout. You can keep a backup of your settings using the backup and restore of tab or use a surge protector to prevent the loss of these parameters in case another failure happens to your router.

The problem of duplication of IP was probably due to the outage as well.

  • IE shows a white page that happens with 'All white' no Favorites

    I use Firefox 99% of thetime, but go to IE from time to time. Yesterday, I went to IE, and when I clicked top on the blanks came only and the page is blank, I could not even all bookmarks or whatever it is. It was working fine last time I used it. I had to do a restore from the last update a few weeks back, but I don't think it would make any difference because it was working fine before. With IE now, a white page just comes up with a tab on the side she also reviews on the blanks. Nothing at all. No idea why it happened or what I can do to solve this problem of IE?

    It seems that two things must happen... Three if you don't have good backups (it would be the first thing * if * you have not any outside of the machine.)

    (1) the material must be tested.  By restarting and pressing the combination of keys at the right time could test the hard/readers/speed control (CTRL + ALT + D, on a dell computer before starting at startup of Windows.)  For other tests - Dell probably put on a partition or sent a CD with the machine that allows you to perform a battery of tests on the... video, audio equipment, etc.

    (2) a restoration clean install a factory should probably be made * if * hardware testing are in agreement.  You could probably clean the machine by following the steps I'll give you - but knowing no more about the problem that we are so far... If that does not better... it's perception, or something so serious, that a clean install is probably the only real 'next step '.

    (And if the new facility does not solve it and analysis of material found nothing - that's the perception, or something (material) defective which is not be picked up).

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

  • The GT630 that came with my HP h8 - 1360t output VGA for my HP w2007 monitor?

    I did research on this issue since about an hour and have not found an answer 'solid '.  There is no VGA/DB15 port on my video card and NVIDIA site presents DB15 ports when their 630 s.

    So I ask

    1. Why are there no DB15 port on my card?
    2. The GT630 that came with my HP h8 - 1360t output VGA for my HP w2007 monitor?
    3. Maybe this'll work via the HDMI port?
    4. I get full/native resolution?
    5. I have the NVIDIA GT 630 or 630 GT OEM?

    Thank you in advance for you help.

    With the help of a PC HP HPE h8 - 1360t, monitor HP w2007, Win 7 and I am very grateful!

    Thank you for the updated information.  Unfortunately, I can't say that the OEM version will allow the adapter VGA to add or not.  I have found no information about this issue and I don't have access to a review and provide a precise answer.  If someone has done this, feel free to chime.

    About the add-in VGA, remember that the back plate will have a slot for him as well. Personally, I do not recommend physically modding any component due to the concern about security.  You might want to consider the limited warranty.

    The big problem, as you will encounter, but most computers use DVI - D.  VGA is purely analog and DVI - D is only digital.  Most PCs now use DVI - D, which will not work with a simple DVI - VGA adapter.  The converters that would a DVI - D to work with VGA are generally expensive (even more than a DVI KVM switch).  There are DVI - D to VGA adapters that work, but they are rare and usually not specified.   It'll be cheaper to start with a DVI - D to VGA (provided that the DVI port is DVI - D).  This claims to be a DVI - D to VGA.  Base don this siteand the image, the adapter doesn't seem to be an adapter DVI - D dual link would work.  However, some reviewed said that he is in reality a DVI - I adapter that would work for this scenario unless the video card's DVI - I instead.

    The following options would be to use a KVM DVI switch or upgrade the monitor.  From my research, it seems that he had options in two similar categories in the price.

  • When trying to download or update msi programs and it's got to the part of the installation, I get the Error 1606 could not access network location % APPDATA%\. This only happens with programs of msi.

    This only happens with programs of msi.  I used the fixit for me solution and it does not solve my problem and I'm afraid to mess with the registry.  What can I do now?  I am running Vista Home Premium.  I don't know exactly what details you want.  Just ask and I'll try to provide answers.

    Sorry to take so long to get back to you - but I have tried different things to try to solve my problem.

    I was able to upgrade Silverlight without problem.  But failed to update Adobe Reader or Java.

    I ran the Microsoft fixit to resolve the Error 1606.  These are the 50356 fixit.   Microsoft help page says:

    "This problem can occur if there is an incorrect setting in one of the following registry subkeys:"

    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders"

    It did not work.  I went to the support page that you recommended and ran the fixit there - and who did not.

    Then I noticed that this fixit 50356 mentions 'current user' - so I tried to change my standard account to an administrator account.  It basically gave me two administrator accounts.  (I already had a separate administrator account and was simply put the password so that it will prompt to update Java and Adobe.)   Then I tried to update Adobe Reader by using the new administrator (officially a standard account) and had no problem!  Then, of course, the problem has been to my administrator account.

    I'm guessing that the Microsoft fixit didn't work is because I was on the internet using my standard account, not my administrator account.  So, it 'fixed' my standard account, that does not need fixing.  I can't connect to the internet using my administrator account, unless it is necessary.

    It would be useful that the Microsoft help page has explained that the problem is probably in the administrator user account that is used to download and upgrade programs, that the fixit solution that they recommended would fix the problems only on that account, and I had to log on that account, connect to the internet and then running the fixit.  But it doesn't work.  It just says: If you get the Error 1606, run this fixit.

    I changed my new manager at standard and I'll connect to my normal administrator account and run the fixit from here.  If this is the problem with this account, I will be setting up a new administrator user account and delete it.

    Thank you very much for taking the time to try to help me.  People like me who do not know much about computers need people like you to help us!
