WPA is safer as all in all it's a lot harder to crack due to being a lot more characters in the passkey. The easiest thing to do would be explain how i have mine set up. And you could compare the 2.. As i have XP Desktop & Vista aswell. So your Laptop connects ok now but is still an unsecure network.. On your Dektop. When you try to connect. Are you entering the 26 character key on the bottom of the livebox?
The main thing to realise with the Livebox is everything is reversible.. And to not worry about changing something..
So let's get this started, When you open up the " Connect To A Network " you can see your Livebox-XXXX. Next to that does it say "Unsecured Connection"? If this is the case then your Livebox is still not properly configured.. What i would recommend doing is starting a fresh with the Livebox, and i explain how to set it all up from Default.
IF you don't remember your internet login details then go to "Configuration.adsl" and click My Services then Internet. Your info will be in there. Hopefully you remember your password..
If you don't know how to do a reset of your liveox. Press and hold the "1" button on the back of your livebox. Unplug it from the mains whilst still holding the "1" for 10 seconds. Then plug it back in. [ still holding the "1" ] The lights will flash a bit and after a minute or two it will go back to normal.
Go back to "configuration.adsl"
If i start from the top section and work down it should make it easier to follow:
My Services>Internet>Connection Parameters Filled In..
Phone Over ADSL> Nothing needs changing
Digital TV> Nothing Needs Changing.
Liveprinter> Nothing Needs Changing.
Security> Associated Devices> Will Be Empty
Wireless Connection> Channel Number> 11
Security Key(WPA-TKIP)> Same As What's On Bottom Of Livebox.
Enable Wireless Lan> Ticked.
Configuration> Update> v5.10.7-uk
Administrator> Change the password while you're there..
Advanced> Wireless> Pairing Time> 10 minutes should be fine.
Your Livebox name can be left as it is.
WPA Security Only
Wi-Fi Easy Pairing.. Might aswell leave it on..
Now if we set up your laptop first.
Go into Connect To A Network. Your Livebox should be there. It also SHOULD say Secured Network. If there is a Red Cross then you will need to do what i suggested yesterday on my previous post.
Go back to connect.. Enter the 26 char. passkey with caps lock on.. And you should be connected no problem.
Now for the Desktop.
when you log on.. In the taskbar in the bottom right should be something to do with wireless networks. Double click this.. If it mentions something about using the software that came with the device.. Then use the software.. If not then windowsXP will show your network. Double click it.. Enter the same 26 character code.. And you SHOULD be connected.
Let me know if that works.. Sorry for the really long post, but detail is something i do quite well...
