WEP can be cracked for 1-2 minutes. WPA might require many days. WPA2 will take reasonable amount of time of you have the password in the dictionary if you are performing brute force. If you do not have such word. So far WPA2 is a very good encryption which is if implemented properly can protect you.
Move as close as you can to your wireless router, and if your router has an encryption lock (WEP or WPA key), disable it.
They're likely not 'your' access points, they are other people's. If you don't know their encryption keys, then you are not supposed to be using them - get your own wireless router. If you do have a wireless router, and that appears on the DSi, then you need to enter your own encryption key from your router, to let it access it.
The WEP key is the encryption code needed to access a wireless router.
The router supports encryption and authentication
Wireless routers can be secured by using different types of encryption, which require an encryption key to download. So if your router uses 'WEP' encryption, then you'd select WEP on the PSP, before entering the WEP key specific to your router.
It sounds like your wireless router is using WPA encryption, which a DS or a DS Lite does not support. Try looking in your router documentation, and see if you can change it to WEP encryption instead. A word of warning, WEP encryption is not as safe as WPA.
It's very easy to secure a wireless router, but be sure to use WPA2 encryption, as WEP is very insecure.
Pick it up and slam it against the wall!
The WEP key is the encryption code for your wireless router. It is sometimes written on your router itself, but will be stored on your computer so it can access the router itself. If you do not have a wireless router, then you are actually seeing someone else's wireless hotspot. If it is not a public one, then it's not something you are allowed to use - the WEP security is exactly there to keep unauthorised people off the network.
wireless modem is called that because it has a wirelss router built in. wireless router just a wireless router. if your cable is not wireless you can buy a wireless router or a cable modem with wireless router
You have to enter the router's encryption key, or disable the encryption on the router itself.
WEP, or Wired Equivalent Privacy, is a kind of wireless encryption. So if your wireless router is using WEP encryption, it will have a passcode to allow your devices to connect and use it. That is what the DS is asking for.
