Trouble connecting to 16bit WEP network

I am using an IBMR50e laptop, running Windows XP professional. As my laptop did not come with built in wireless, I am using a Netgear WG511U adapter. The trouble is this: I have succesfully set up (in my apartment bulding, for use on 4 PC's) a wireless (11G) network using a Linksys W54GC router (currently, the network is protected by a 16bit, WEP passkey). The wireless network is accessible on all of the other PC's in my building but mine. Specifically, here's what's going on: when I scan for the network, I see it no problem. If the security on the network is turned off, I connect and am able to browse the web. If security is ON, then my adapter still connects to the network, but when I open my browser, I get a message from my browser(Mozilla) reporting that it cannot connect to the web. Everything works fine without security, but the moment I enable the WEP password, I can no longer connect. I have verified multiple times that I am entering the passwphrase correctly -- and to make sure that I'm not making some mistake, I've tried entering the same password alternately in the "passphrase" and "manual key" fields offered to me by the network adapter software. In neither instance am I able to connect. Here's some speculation that might help the kind soul who can assist me: when I purchased the laptop, it came with "AccessIBM" wireless software already installed. The odd thing is that I can't seem to disable the AccessIBM software (but the option to only use the AccessIBM software doesn't work, as the NetGear software needs to be running to use the NetGear adapter). I've been able to connect to unprotected networks without any problem, and I wonder if the issue with the protected network is that the AccessIBM software is somehow interfering.

    Thank you thank you -- the problem was with the length of the key that I set. Everything works now -- I sincerely appreciate your reply!

    I have a netgear wg511t wireless card it connect to the network but will not connect to the internet.

    If I take the card out and use the card in the laptop it works fine, I was tring to increase my speed with this card.

    Same problem - connect fine as long as not WEP can connect to other networks not WEP. What was the remedy??? ATT can't supply an answer - go figure.

    I recently started having the same problem.  Any network that is WEP enabled I get limited connectivity.  I am positive that the network keys I enter are correct, its really weird.  One day it worked then all of a sudden it stopped.  Interestingly my IE doesn't work as well.  It just displays a blank page and will not load any pages on the internet.  I wonder if the issues are related.

    what if it says, as netgear does, a 64 bit pass phrase????

  • ssammee May 11, 2010

    what if the IP address returned is 192.168.x. x ????

    I have the exact problem but will the remedy be the same?

    Got the runaround for 2 hours from wireless providor w/out answer except we don't know but you can pay for more qualified technical help and wireless card manufacturer won't talk to me because its out of warranty - even though its not a product malfunction, just a question of configuration. Where IS customer service from either vendor? I'm so frustrataed.. I keep saying its a simple configuratation issue, it isn't a singular problem, there has got to be an answer other than someone else may be able to figure it out...

On wireless networks, there are 2 stages of connecting. The first is associating with the Access Point. The seconds is properly authenticating to the Access Point. It sounds like the first stage is happening fine. The seconds stage (encryption) is where it sounds you are having the problem. With out successful authentication in the 2nd stage, you will not be connected to the rest of the network. The reason why you cannot get out to the Internet is probably because your laptop never received an IP address via DHCP. This can be confirmed by opening a command prompt (start -> run -> Type "cmd" (No Quotes) -> Hit OK) and executing the following command: ipconfig /all You should have a 192.168.x.x IP address. If you have an address in the 169.254.x.x or range, then your laptop did not receive and IP address and will not get out to the Internet. The cause for you not getting an IP address is most likey due to the encryption keys not EXACTLY matching. This often happens when using different vendors products, as their implementations are not always EXACTLY the same. From what you mentioned above, 16 bit WEP key does not sound like a standard length. They are typically 10 or 26 bit. What I would recommend is that you set your wireless clients and wireless router to the EXACT same settings. When doing this, do not use pass-phrases or ascii characters, as different vendors may produce different keys, and this may be causing your problem. What you want to use is a 10 or 26 character string of the digits 0-9 and the letters a-f. This is known as a hexidecimal string. This is the one sure way you will have exact matches on both sides. One example of a 26-bit WEP key would be the following: 8005532447badfad8005532447 Note: The letters can be uppercase or lowercase. Hexidecimal characters are case insensitive.

I'm seeing many reviews for this device that imply they are not very reliable and may not work even out-of-box.
My first question is why can't you simply get a USB 802.11 device to use with your WiFi? XP can connect to any WiFi as long as it has a wireless network adapter installed. It only has native support for WEP encryption, but with SP3 installed you have support for all wireless encryption standards.

Most laptops have a built in program to run to check the functionality of the hardware built in. To start the tests you normally have to restart your computer and then press a certain key during boot up to access the programs. You then choose which tests you want to run. This could also be caused by a bad USB cable. You may have already done so, but if not try connecting the devices using a different cable. You could also try the device using the cable and USB port that you know is good because you are using it now.


Can't connect to my router anymore (WEP encrypted).

Hi deray953,

First we need to remove the previous profile in your wireless network. I believe you know the SSID for wireless connection using WEP security. You can check this by going to;

Using Windows XP SP2/3
1. "Control Panel" > Switch control panel to classic view ( look at the upper left side ). > Double click "Network Connections" > Right click "Wireless Network Connections" > choose "Properties"> Click the Tab "Wireless Networks" ( middle tab) > go to the list of profiles and remove the Wireless name or SSID for your home connections. > click OK and Close the properties of wireless.

To reconnect again, you need to know your WEP key or network key for wireless connections if not, you can do this procedure...

1.Connect the computer to one of the four LAN ports (i.e port 1, 2, 3 or 4) on the back of the router. The corresponding port light where you connected the computer should be lit up.

2. Access the router's web-based utility.

a. Please open any web browser like Internet Explorer or Netscape Navigator.
b. Connect to the router by typing or in the address field and click Enter or Return key.
c. A window will prompt for a user name and password. By default, the user name is "admin" and the password is "password".
d. Click on the Wireless Settings under Setup.
e. take note of the KEY 1 ...that is your WEP key..take note of it.

Windows xp problem


It seems you installed an outdated (16bit Program) for the ScanMaker 4. 16Bit applications/programs and generally DOS based (Windows 3.x and 95) and will not run properly from Windows XP.

First, check and download and install Drivers and Plugins for Windows XP.

You may need new 3rd Party Scanner/Image Applications that work in Windows XP. However, if you still want to use the 16Bit application then you will need to run the program in 16Bit Compatibility Mode. To do this, right-click the program executable or shortcut, choose propertise from the drop-down menu, go to the Compatibility Tab and put a tick in "Run this program in compatibility mode for:" From the drop down menu, choose Windows 95 or 98 and apply.

Finally, check the the User's Guide or ReadMe file(s) (if you have it) for more info. Especially, check the recommended OS for the Applications.

I might be wrong, but i think ScanMaker 4 has a SCSI interface. If this is correct, then your laptop or port replica must have a SCSI port. NB: SCSI is not the same as Printer LPT Port.
