If I modify the settings and put in a wrong WEP passphrase, I show that I'm disconnected. But when I change it to the correct passphrase, it shows I'm connected...

Are you using the passphrase to create the hex WEP keys on the router, and then copying the hex keys into the TM1300 setup on the laptop? Unless the devices are from the same vendor, it's unlikely that the code that generates the hex keys is the same in both devices. Transferring the hex keys eliminates that possibility.

I think I may have the same problem. I have entered the same 26 digit numeric code on my Router - Dlink and my TM 1300 but no connection to the internet even though it shows that there is a signal. I am not sure I understand your suggestion.

 

Thanks

The 26 digit numeric code should be the same on your router and on your TM1300. The issue I described is that if "passphrases" used to generate hex keys, different manufacturers typically use different algorithms to create hex keys from passphrases. And that will result in different hex keys.

That means "passphrases" aren't portable between manufacturers. Hex keys should be portable between manufacturers.

104 bit WEP keys (excluding the 24 bit dynamic initialization vector) are 13 bytes, 26 hex digits, or 104 bits in length.

Did you perhaps not enter the key correctly into one or the other device? Are the TM1300 drivers and the D-Link firmware current?

Jim

Thanks Jim. I have verified that my hexkey is exactly the same. I have this working on another wireless connection in my home.

OK, I'm stumped! What you've done sounds entirely right. Perhaps someone else can help.

I have the same problem with 2 TM2300...

Just bought 4 Latitude and one X300, everything works perfect until I turn on encryption - then I loose connection and must reconfigure the NIC. I can then connect, but I will not get any new IP-adress from the TM 2300!

I´v tried both WEP and WPA with different settings, no encryption is possible.

Firmware: 3.0.0.8 (07/24/2003)

I am having a similar problem. I have a TM 1300 on an Inspiron 8600. I can connect to the wireless router with WEP engaged. However, after about 15 minutes I get dissconnected. I have to then reconnect. It happens every time. The only way to avoid the disconnecting issue is to not use WEP on my router, then I never get disconnected. I have been on the phone with Dell Support & I have tried the following with them:

Latest card driver installed and changing from HEX to ASCI encryption. Neither of which solved the problem. Dell has given me the impression that there is nothing they can do about this problem & it is a known issue with this version of the wireless network card. However, I have not been given any alternate Dell card that would avoid such problems.

If any one has a solution I am all ears.

It's just a thought, but could it be that your AP won't pass the DNS address(es) through to your particular laptop / card combination when it is running with the WEP encryption? I have hit this problem before with a Netgear DG834G router.

The test to check is easy: when your laptop says you are connected, open a command window (click on 'start', click on 'Run' and then type 'cmd') and then ping a known DNS address - try 4.2.2.2  (i.e. type 'ping 4.2.2.2')  If you get a response, you really are connected. (If you don't get a response, you're definitely not connected and you can forget the rest of this message). Then try pinging, say, www.yahoo.com. If you don't get a response, you definitely have the DNS pass through issue. Solve it by

1)  opening the properties of your wireless connection, selecting the TCP/IP properties and specifying a known DNS address (like the one above), or

2) Getting a firmware upgrade for your AP. Oddly, the firmware upgrade for my Netgear router, although suggested by Netgear, didn't come from them, but was a 3rd party fix from http://htff.co.uk/netgear/index.html

I hope this helps :-)

You also may want to make sure the TM 1300's power save mode is disabled.
