Hey guys how are you doing.

I just bought a new samsung laptop and i was not able to connect to my wireless router
--I go into Wireless Network Connection and i am able to see my router along with the other routers in the area
--I try to connect it doesnt let me, i change the pw on my router doesnt let me, i remove the pw from the router doesnt let me.
--I connect a Ethernet cable to my laptop, im able to connect.
--i Go to the samsung website dl all the drivers for the wireless network, cant connect
--I use a wirelss adapter that i have for my desktop which works on my desktop, it cant connect
--i grab my little brothers cell phone and activate wireless hotspot, i can connect
--i switch my router settings from WPA2 Personal to WPA, i can connect
--while connect to WPA i switch it back over to WPA2 personal, i get disconnected.
my question now is. why cant i connected to WPA2 personal? Is my connectivity limited on my laptop? can i only connect via WPA or WEP?

--Asus wireless router i connect my tablet,cell phone adapter with my desktop, 2 other phones, another 2 laptops, 2 other tablets and another desktop to it. I never had an issue with any of these items.
--Windows 7 on all machine except for Linux on 1 laptop.
--Samsung laptop has all the windows updates install and all the drivers for the network and even gpu up to date.


I want to connect to my WPA2 personal. that is my objective.

You're wireless adapter does not support WPA2 Personal, that's why you can't connect when the router is configured for it.

You have only 2 options:

1. Configure the router for WPA.
2. Replace your wireless adapter with one that supports WPA2 Personal.

I was coming to that conclusion, but how can i know that for sure before i make a purchase?

you know what i mean? like how can i determine by looking at just the specs that it doesnt support WPA2 persona?

The fact that it won't connect is all the proof you need.

Look at the manufacturer's website for the model in question. You want the full specs list. If you don't see WPA2 Personal listed as one of the wireless protocols then it doesn't support it. If no protocols are listed then you'll have to contact the manufacturer directly and ask.

Hard to say why doesn't work it is a newer machine. The key to look for is 802.11i that means wpa2

Your other option can you get it to run wpa and aes.

The only real difference between wpa and wpa2 in personal mode is the encryption. WPA2 supports aes and tkip with aes the preferred. Since wpa was never a true standard many vendors added aes support which in effect made it wpa2.

It is highly unlikely it will matter nobody attempts to crack the encryption itself. They attempt to obtain the encryption key by intercepting the handshake messages to determine your preshared key. This is done exactly the same on wpa and wpa2. As long as you us a key more than 6 characters that contains any special character it is calculated to take more than 10 years to get that..so just change your key more than one in 10 years :) 

The biggest security exposure routers have is the WPS feature. You must keep this disabled as much as possible. It only take 10 hours maximum to obtain even the most well designed keys.

I would just run wpa with a good key and be content the hackers will be occupied hacking the people who are using WEP or have left WPS enabled.
