Why won't my computer install the driver for CT-5621T Router?

I'm trying to set up an internet connection, but I can't get the driver to install. When I put the disc in, the auto run runs fine, but when I click to install USB drivers I get this message: Windows cannot find DPInstx64.exe. Make sure you typed the name correctly, and then try again. What can I do?

SOURCE: cannot connect second computer to my networn

I have listed several things here that you can use to find the problem. Sorry this is so long...network problems can be very tedious to find.

First check your version of Windows:
Double click on "My Computer", then click on "View System Information" to make sure you have at least Service Pack 1...or better yet....Service Pack 2.

Next check your Windows XP network settings:
Click on Start....Control Panel....Network Connections...Local Area Connection...Properties(button). Scroll down the list to find Internet Protocol(TCP/IP) and click on it to highlight it. Now click the properties button below the list. You should now be able to click the small buttons to select both of the "Obtain....automatically" choices for IP address and DNS server. Click on "OK" to close each of the windows.

Now you can test your computer to see if it is "talking" to the router: Click on Start...Run...and type "cmd" in the small box and click "OK". This will open a black command window where you tell the computer what to do. Type the command "ipconfig" and press return (enter). This will list your ip address, subnet mask, and default gateway. Make a note of the default gateway address so you can use it for the next test. If the IP address begins with 192.168...then your computer is probably communicating with the router okay. If your IP address is blank or starts with 169...then your network connection to the router may NOT be working.

The final test!!! Use the default gateway address from the last step to do a "ping" test. In the black command window...type "ping" followed by the default gateway address. For example: IF the default gateway happens to be 192.168.1.1....then type the ping command this way: ping 192.168.1.1

If the result is a list of replies from the gateway address...great!! Your network connection is working. If the ping command results in a list of "request timed out", or something else, then your network connection needs more help.

The ultimate test is to try using the Internet with your browser.
If this works, next try typing your gateway address into the brower address bar. It should connect you to the router setup page.(?)

Let me know the results of each of these tests, and I'll be happy to assist you further, if needed.

Try this one Enter your username and password, By default both the username and password are admin. Click the Ok button to log in to your router.. If the default username and password wont work the next step here is to reset the router so it will be back to its default settings with the default username and password....

SOURCE: Windows Startup Error csrss.exe

Okay, we are going to try two things. If the first don't work go to the second.

1) First perform a search on your computer for the 'csrss.exe' file. If found, copy it and then paste it into your C:\windows\system32 folder.
That should do it.

2) If that don't do it or your search can't find it, then perform the following;

To scan and verify the versions of all the system files that Windows File Protection protects, use the System File Checker (Sfc.exe) tool together with the /scannow parameter. If the SFC.exe tool detects that such a file was overwritten, the SFC.exe tool retrieves the correct version of the file from the Dllcache folder or from the Windows installation source files, and then replaces the incorrect file.

To run SFC, please follow these steps:

1. Click on Start > Run command prompt
2. Type SFC /scannow, and then press ENTER

Note: You may be asked for inset OS CD.


3. After finishing SFC, you may run CHKDSK C: /R in the Run command prompt as well.

I have wireless Internet! I have a laptop, I tried to connect to it~ It will connect to the router, but won't connect to the Internet! Help!


How many wired and wireless computers do you have ion the network.
Do you have any wired computer ?
Connect your laptop to the router with the Ethernet cable and try to access Internet. See if the wired connection is working or not.
If the wired connection is working then I think you will need to check the wireless settings of the router and the laptop.

Hi,

Improve the Fixya.com experience for everyone by voting!

Subject: No wireless connection from router cannot connect to the Internet.
Solutions: Straight Connection, Windows Connecter and Microsoft Fixit

Discussion: I'm going to provide you with three solutions and between them you should get online. However, you should be advised that in order to fully analyze and correct any difficulties you're having, we should be chatting or on a telephone connection. All I really know at this point is that you can't connect to the Internet through your router.

I'm going to give you three FREE general fixes and let's hope that one of them will work for you. If not, then we have to chat.



Now, let's see if I can help you.

The first solution I'm suggesting works in my business (LAN installations) about 95% of the time. I trust that it will work for you.


Begin by turning on your computer and your router

? Make sure your service provider has activated your account and services on the subscribed line. Please check with your service provider to confirm this.
? Make sure that you are using the latest drivers. You can download the latest driver from Driver Downloads Database.
? Make sure that you have entered the right username and password (case-sensitive) as given by your service provider. For example, in Australia: user@bigpond; in NZ: user.name.xadsl@xtra.co.nz.
? Open Internet Explorer;
? Click on 'Tools';
? Click on 'Internet Options';
? Click on 'Connections';
? Click on 'Setup'
? Click on 'I want to set up my Internet connections manually . . .';
? Click on 'Next';
? Click on 'I connect through a local area network (LAN);
? Clock on 'Next'
? Click on 'Next' [This is not an error];
? Click on 'No';
? Click on 'Next';
? Click on 'To connect to the Internet immediately . . .; and,
? Click on 'Finish'.

That should have you online.

However, if the first solution doesn't get you connected, do the following:
• Click on tools again.
• Click on 'Diagnose Connection Problems'
• and follow the instructions.


The second suggested solution is to use the Setup Wizard. It seldom works for me but you might have more luck than poor me. Here are the instructions:

The Connect to the Internet wizard will guide you through the steps of setting up an Internet connection.

Open the Connect to the Internet wizard by:

• Clicking the Start button Picture of the Start button
• Click on Control Panel.
• In the search box, type network,
• Click "Network and Sharing Center"
• Click Set up a new connection or network
• Then double-click "Connect to the Internet".

The third solution requires an Internet connection. I'm going to pass on to you a FREE and hard to believe program from Microsoft called Microsoft Fixit! I have no idea why this little program hasn't been advertised but then I don't own their stock.

Just click on the following link and your problem should be solved: Download Microsoft's Fixit

You'll see the following areas in which Microsoft Fixit can solve software , hardware and just about every other problem you may incur. They are:

Top Solutions Windows Internet Explorer Windows Media Player

Entertainment Office Other

I suggest that you try top solutions and 'automatic' before exploring the other titles.

Be a hero and fix your friends' computers; just don't tell them how you did it! That will be our little secret.

All the best

My wii won't connect to my cisco e10000 and I already checked the security settings !!


you will have to open up your network connections click start control panel network connections this may vary depending on your operating system look for local area connection if you see a red x or a yellow exclamation or question mark you will need to update or install the driver or it could be firewalled
make sure your modem/routers settings are correct ie:password user name,firewall settings to allow your internet to connect also test the lead/s whether usb or ethernet you might check your modem first to make sure that you are getting a connection
click start control panel administrive tools computer management device manager scroll down network adapters + expand Ethernet driver you might see a yellow question mark? This means you need to update the driver right click you will have options to update driver disable uninstall or select properties general you will have the options to troubleshoot or to update driver rollback or uninstall
a yellow? question mark means you need to install/update driver right click to install driver
last resort ring your ISP internet sevice provider get them to check your modem for internet access online
hope this helps i just read something on the setup of a cisco
Use the Cisco connect software for the initial set up of your new E series router. While running the software for the first time it will ask you to connect the modem to the router. But will not ask you to connect the computer to the router. However it will be better if you connect the computer to the router with an Ethernet cable. Otherwise it will not find the router and you will get the error "we did not find your router". Run the program and at the end it will connect you to the Internet. You don
