    Have you tried resetting it back to default? As far as I understand, your recordings should remain intact.

  • richard caddick Mar 28, 2015

    Yeah i tried to do that but cant nothing till i get passed the admin/ password page. Not worried about losing data just need to reset dvr box or access the default code to change the password if you need any info on dvr box plz ask.

SOURCE: Forgot linksys password

Reset your Linksys router back to default:
The easiest method of resetting your Linksys router’s password is to reset your router back to the default factory settings. This is done by simply holding down the reset button located on the back of the unit for at least 30 seconds. Once the router has been reset, it must be reconfigured. Using your web browser go to URL address You will then be prompted to login to your router. A log-in screen asking for the password will automatically appear. At this time enter the default password “admin”, in lower case letters into the password field. The username field may be left blank at this time. (Note: both the default username and default password are set to “admin” on some of the newer Linksys router models).

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

SOURCE: dell inspiron 5150 laptop, reset admin. password.

Restart your laptop and keep tapping F8 key the moment you see something on the screen. You will get a black screen with some options written in white. Select the option Safe mode and then you can create a new user with admin rights. Or else at the windows login screen press and hold ctrl and alt key and tap delete key twice and then it will take you to a login screen. Dont put any password there just hit enter. And you will be able to login with admin rights.

SOURCE: Dell Latitude D630 admin password lost

You can take care of this yourself. With the laptop off, unplug it, and take the main battery out, and open the screen back until it can't open any further. Take a small flat-blade screwdriver and put it into the small vertical slot on the right end of the bezel plate just above the keyboard. Pry that up, it will tilt to the left wiggling it as you pull it up and off. When that goes back on, the left end goes in first, re-snapping it back down. Set that aside. Looking at the top frame of the keyboard you will find three small Philips screws that need to come out. Use a #00 Philips (you can pick one up as Sears if you don't have one). Set those aside (they are all the same size). Gently pry the upper edge of this keyboard frame up and it tilts toward you, then you pull it toward the LCD screen to release the tabs that hold the bottom edge of the keyboard under the palm rests. Don't yank it off, there is a cable holding it on the left side! Just fold it back and let it rest over the trackpad, no need to release the cable. Look into the now open area and about 1/3 of the way from the left side you will see a tiny white plug with two little wires attached, red and black that go to a little "coin" battery. This is the CMOS battery that keeps configuration data from being lost when powered off. Grab the wires closest to the little plug and pull it straight up, wiggling it left to right if you need to. Leave it unplugged for 10-15 minutes. Plug the little white plug back in, fold the keyboard back into it's normal place maing sure you push the bottom tabs in first, then be sure you snap the sides back down at the right and left edges and under the little side tabs. Put the three little Philips screws back in and reinstall the bezel above the keyboard. You have cleared the BIOS settings including the password to get into the BIOS. Close the lid. Flip it over. Put the main battery back in. Plug in the power cord, flip it over again, open the lid and hit the power button. Press F2 while you see Dell on the LCD screen and you will get into the BIOS Setup without a password, it is gone.

I forgot my admin password i got a H.264 dvr 4ch China made

Admin and Passwords come as default. If you changed it and forgot, try unplugging the DVR and restarting. You can also still open the settings and try to re- factory the DVR if the settings permit. Next, I have to assume that you got the Booklet or the email or URL addresses to download same.
There is in the hand book the default password as the User name:password and the Password #'s 1-6. Good luck.
