WRT120N is no longer recognized by laptop computers

I'm not sure where the problem lies, so I'm going to review everything that happened so I can hopefully get an answer. Any help is VERY appreciated.

We ran a few portable computers (Acer Aspire 5517 on Vista) off the coast of our wireless router WRT120N. We have hooked to a wireless modem. All signs show that the modem and router are working well. The wireless network we were using, I'll call it network-1, stopped to appear as an option in the wireless connect menu. Previously all laptops can connect to the network-1 wired or wireless without problem. I don't know what happened to start the problem, but the network-1 is thus more a wireless network option.

When I have a laptop from wire to the router, it connects to the internet and says it is currently connected to the network 1. But when I try to connect to the network wirelessly via a wired connection, the new network, I put does not appear in the connection menu. When I try to configure the router again (while the computer is connected), I get the error message "Windows doesn't detect any wireless network hardware. It seems that, although I am able to get internet connection through the router, the computer does not recognize it.

One laptop is able to connect wirelessly via another network (Network-2). Looks like that Network-2 has been set up automatically by the laptop. Another laptop has Network-2 as an option, but it indicates that the network security key is bad. I have no idea what could be the password, the computer which is running network-2 automatically connect, I don't have to type a password. I don't know what happened here, if it's two different connections with the same name, or if it's the same thing. I don't even know if this is relevant.

Yet once, SO we would be grateful for any help!

Well I think that for some reason any the wireless settings of your router must have reset to zero, that is the reason why you can not see the name of your wireless network. If you need to you computer to the router and connect on the router configuration page and change the settings of your router wireless.

Open an Internet Explorer browser on your computer (desktop) wired page. In the address bar type - 192.168.1.1 and press ENTER... Let the empty user name & password use admin lowercase...

For wireless settings, follow these steps: -.
Click on the Wireless tab

-Here, select manual configuration... Wireless network mode must be mixed...
-Provide a unique name in the name box of the wireless network (SSID) in order to differentiate your network from your network of neighbors...

-Set the Standard - 20 MHz Radio band and change the Standard channel to 11-2, 462 GHz... Wireless SSID broadcast should be enabled and then click on save settings...
Please take note of the name of the wireless network (SSID) because it's the network identifier...

For wireless security: -.
Click the sub-tab under wireless > Wireless Security...

Change the mode of WPA wireless security, encryption, select TKIP. Password input your desired WPA key. For example, MySecretKey, this will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and do not forget the key.

NOTE: The password must be more than 8 characters...

Click the settings advanced wireless

Change the tag to 75 interval, change the Fragmentation threshold to 2304, change the RTS threshold to 2304 and click on save settings...

Now let's see if you can locate your wireless network and try to connect...

    The case holding the Maxtor no longer works or the Maxtor drive itself is a failure. Your first step is to contact their technical support.

    http://www.Seagate.com/www/en-us/support/

    It is a perfect illustration of the reason why you cannot rely only on an external hard drive for backup. You have to burn to DVD - R on occasion or using a service like Mozy offsite backup. Hard drives are mechanical devices, and like any other mechanical device, they can fail.

    If Maxtor (Seagate) tech support determines that your hard drive has failed, you can still get the data on it, but only by sending the drive to a professional data recovery company. I use Drive Savers for my clients, but there are others. Professional data recovery is quite expensive, running with an average of about 2700 $ $500-$3500.

  • Y50-70 - USB Reader and card reader no longer recognized

    I have Lenovo Y50-70 (running Windows 10) and my WD My Passport Ultra external drives are more recognized (they worked fine until 3 days ago). My card reader CF is no longer recognized either. My Samsung Galaxy S5 works well.

    The WD My Passport drives Ultra both my card reader still work with my older ThinkPad, which works in Windows 7. This isn't a disc problem, or a cable problem.

    When I look in devices and printers, the WD My Passport Ultra appears. It has the following warning sign for troubleshooting option. When I troubleshoot it comes back telling me that the driver is not installed. Continuing, he finds the driver, install it and asks to restart the computer. After the computer restarts, the drive still does not appear.

    When you look at the properties of the drive, it says that the driver is not installed and an error code 28 the list.

  • Installation of XP is no longer recognized by the Setup disk after Format of Partition

    Hey all,.

    In short, my problem is that I have an installation of XP (home or professional) intact windows, but after deleting another partition, the computer does not start to it. My question is what are all the things needed for a computer can be started on the windows partition - even just to the loading screen (which files are needed on the partition, for example boot.ini file, which must be in the MBR, how to mark a partition as bootable; etc.). Here is a description of exactly what has happened and what is the current situation:

    I was working on a friend's computer, and he asked me to delete the partition that it has not been used (D) and melt in his primary partition (C) where was the installation of Windows. I used a program called Easeus to format the partition for Windows let me to merge. The program asks for a restart, and then it is initialized to a screen where he deleted the partition, then restarted once again, probably to load Windows.

    That's where the trouble starts. Instead of windows, I have nothing else than a cursor flashing ("_") in the upper left of the screen. After 60 seconds, nothing was. I rebooted a couple of times, still no windows.

    The first thing I tried was to throw the disc to reinstall the window. I got to the screen configuration and supported on entry to choose a windows installation to repair, however he could not find one on the drive C (or D). I then tried to install Windows on drive D, hoping at least to be able to access the files on your computer with a parallel installation and then clean things later, but the installation struck a BSOD (sorry I don't have the message). The last thing I tried using the recovery console, but the only one installation of Windows that he found was on the D drive (I guess it was the remains of the failed installation that I had tried just because it contained only a few system files).

    So I still need an operating system to access the files on the C drive, so I did an installation of Fedora Linux (on a small new partition in drive D). I could check on the files and they were all intact, including the Windows system files. I could not find anything wrong with the partition, except for the apparent absence of a file boot.ini on drive C. I tried to add a boot.ini file by default (even though I wasn't sure exactly what should be in it). I can only assume that when my friend had the computer built with partition by a local technology company, they did the D drive partition bootable, but put the Windows files on the C drive. It makes no sense, but I can't find any other reason format another partition that windows would make it unbootable.

    The problem is, now, I have GRUB installed to Fedora. GRUB cannot boot directly on Windows, so he has to begin on an another bootloader that can. I think I have GRUB pointing to the right partition, but I get an error message. So, what I want to know from a point of view of Windows is everything necessary for a successful boot, assuming I can get GRUB to work on his end. What should a healthy Windows boot look - exactly, what should happen?

    The other option, of course, must do a fresh install of Windows on drive C (and hope for no BSOD more). I could put all the files on the partition of Fedora and move them back after the relocation. So what you think - is it worth a try even to save the current installation of Windows?

    Feel free to ask questions or for clarification. I have a limited capacity to test things, I have to wait until I can get to his computer. Your help is very appreciated!

  • I try to install vista on a computer running xp. XP does not even recognize the vista disc is in the drive. XP recognizes any other drive that I use and the vista drive is recognized on other computers, that I put it in it's not a prob with the disk or cd

    I try to install vista on a computer running xp. XP does not even recognize the vista disc is in the drive. XP recognizes any other drive that I use and the vista drive is recognized on other computers, that I put it in it's not a prob with the disk or cd rom

    The Vista installation disc is a DVD. Apparently, you don't have a DVD player. You would need to purchase/install a DVD-ROM or DVD - RW to install Vista. Are you sure that your hardware supports Vista before doing this?

    http://www.Microsoft.com/Windows/Windows-Vista/get/system-requirements.aspx
    Even if a minimum of 1 GB, the requirements in the real world Vista requires a minimum of 2 GB of RAM to run without problem. You will also need Vista drivers for all your hardware.

  • Three laptop computers and benefits

    What are the benefits of having three laptop computers (two panoramas purchased in 2007 and 2009 and a W7 in 2010)?  Since I have access to computers outside my home and at work every day, I use these computers portable "home" to the local library or Starbucks, or at home, for a total of about 10-15 hours per week.  In view of the 'rule' on the purchase of a new computer and also my interest for the loading of black & white oldie films on You Tube, much more quickly than in 15-20 minutes, I'm going to start EXPERIMENTING with one of the three computers laptops etc. 5-7 years, I have now and barely use, IN DESINSTALLANT about half of the 65 PROGRAMS & FEATURES and turning OFF also about 50% of startup items , as well as the Services OF BOOST PERFORMANCE & SPEED and I hope that load much faster films.  Any suggestions will be greatly appreciated.

    You should ask AT & T company, your Mobile or cable what they offer. 0.6 MB/s is slow for me. I live on a mountain and only high speed available here is cell. Cell phone is expensive but my speed is great to 21.6 Mbit/s and only because I live near a tower. Distance and movement affects the cell speed. Your best bet is cable.
