There are 2 kinds of popular wireless security encryption, that’s WPA
and WPA2. One of Lenovo IdeaPad Y430 user said although he already
knew WPA and WPA2 were the newer security encryptions but his IdeaPad
Y430 doesn’t have an option to use WEP. It seems like the WEP is
vulnerable so the option is being phased out. Setting up WPA2 with a
21 character encryption might a good enough for Lenovo IdeaPad
Y430Y430. It will take around 2 years in standard computing power to
break the encryption.
Besides, the wireless router which is less than a year old still has
the WEP option to setup. This is might because of older devices where
WEP is the only option. No matter of which useful one among of the
newer wireless security encryption WPA and WPA2 at Y430 and an older
wireless router which only has WPA, the basic of security set up need
to match are:
WEP to connect to WEP
WPA to WPA
WPA2 to WPA2
However every router manufacturer will have the manual on their
support website for help configuring anything, all you need to know is
what exactly your wireless security encryption model and version on
Lenovo IdeaPad Y430 laptop.
