Wirless networking trouble

[PHTech]

Hey there again.

I'm having problems setting up my laptop with my Wireless D-LINK ADSL router. When I use a WEP key (128-bit) I cant connect with my laptop (I inserted the same key on the laptop).

But when I disable my security, then I can access my network resources. I use the following settings on my D-LINK DSL-G604T Router:

SSID: MyCompanyName
Channel: 6
Security: WEP
Auth. Type: Open
Encryption Key: <128-bit> (26-chars)

I've played around with the Authentication Type with all the available setting, but without luck. The problem is that I need to set security for my Wi-Fi, as there are 3x Other WLANs in range as well.

I would appreciate it if someone can help me on this matter.

THANX!

hhhm, does your router support WPA-PSK(I know I should go onto d-link's site and check, but time is very tight)?

I hae also had issues with WEP, but WPA-PSK usually works quite well, at least from my past experience.

The other option to try, is just plain old MAC access control, which while quite easy to break, will deter any nosy ppl.

Hope this helps. If you have further questions, I will have a bit more time tonight, so shoot.

Do a site survey for available networks and make sure that you are using a different channel from the others (this is to avoid interference). Your settings seem right, i would leave the auth type to automatic. Make sure that your windows firewall is allowing incoming/outgoing traffic to the router. Retry...

AFAIK WPA is far superior to WEP. Have you tried that instead?

 

[PHTech]

I have tried the WPA, but the crappy WLAN card that I am using doesn't support that. The funny thing is, without WEP, its working like a dream, but even with a 64-bit encryption, its totally useless. The PCMCIA card that I'm using is a: 802.11g Wireless LAN CardBus PC Card.

I don't know what else it could be. I have almost tried everything, and want to throw the damn wifi card as far as I can!

If you can come up with any other suggestions, I would aprreciate it.

THANX FOR THE REPLIES!

What OS you using? WinXPSP 1 and earlier does not support WPA - you have to load the WPA update which is included in SP 2.

Im also using Windows XP Pro SP2 with the latest updates. What I have done now, is the following.

--> Held the WLAN PCMCIA card in my hand and aimed for someone I dislike, but on second thought I inserted it back into the Laptop.
--> On my D-link router, I have removed the WEP and any security.
--> Still on the router, I used the MAC address filter and that seems to be working 100%, but my concern is how secure that is.

Logic make me think that a MAC address is unique, and no one in the World have the same MAC address. So each time someone who want to connect to my network, then it's MAC address need to be setup on my router, and so on. I want to test it with my new laptop, to c if the problem is on my router, or setting on my PC.

THANX

Just disable WEP encryption and use MAC address filtering rather.
For extra security measures add a firewall to all your computers.

PHTech, MAC addesses are unique, but can quite easily be changed by the user. It is no longer a hard coded address. It is possible to get through the MAC filtering, by capturing packets, and filtering out the headers. The headers contain the MAC addresses that are allowed. Even though this is possible, it requires a targeted attack, and with any targeted attach, any encryption can be broken in the matter of minutes, so nothing is completely safe. It will however deter 99% of people, and protect your network. If somebody is really keen on getting into your network, they will.

Thanx for the info!

What I'm gonna try is to use a new Wireless Lan Card. I think the one that I am using is a little bit due for replacement.

Well, like u said: If someone wants to break into a network, they will. Im confident that the software I'm using, is real good for keeping unauthorised entry, out.

Thanks for the interrest!
