Hello! You may want to verify your router has the latest firmware and is set up to WPA2 AES encryption only, not TKIP+AES. The same settings will apply for the wireless profile in your computer.
The latest driver for your wireless adapter is 15.6.1 available here: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Wireless+Networking&ProductLine=Intel%C2%AE+Centrino%C2%AE+Wi-Fi+Products&ProductProduct=Intel%C2%AE+Centrino%C2%AE+Wireless-N+2230&ProdId=3507&LineId=1784&FamilyId=1783
Regarding the replacement of the Intel® Centrino® Wireless-N 2230 adapter; note that this adapter is meant to be professionally installed by Original Equipment Manufacturer (OEM) technicians on certified systems only.
Please note that these adapters are not meant to be sold separately, your system must be compliant with the required FCC certifications in compliance with the International Special Committee for Radio Interference standards for radiated and conducted electromagnetic interference.
In this case what we recommend and encourage you to first contact the Original Equipment Manufacturer (OEM) to determine if the product is approved for use in your computer.
If the issue persists please indicate if you are trying to connect with Intel® Proset or with Windows and if there is an error message.
Thanks for the reply Joe.
I have the WPA2 Personal AES in the laptop and same WPA2 in the router except I cannot find anything in the Linksys E1200 that says if it is WPA2 Personal AES or TKIP+AES. It connects most of the time these days and if it doesn't, it will in exactly 1 minute. BUT, it should always connect like the other machines do. It never drops and has full signal.
Windows 8 runs well and does not report any errors and the Centrino 2230 was OEM for this machine is why I wanted to try replacing it with the exact same thing. That is about the only thing left to try. I removed it and re-seated the connectors but that did not help.
I will call the router folks and see if they can give me a clue about the AES-TKIP to make sure I am not there.
I have the 15.6 driver in there and it does not make any difference from the factory installed driver.. I let the Intel program control the wi-fi and now switched back to Windows and that didn't make any difference either.
I contacted the Linksys router tech and she said that I have WPA2-AES+TKIS in the router. I explained that I was trying to get rid of the WPA2 AES-TKIS and just use WPA2-AES like my machine is set for and this is the response :
"Actually, the router's WPA2 security is set to TKIP/AES by default. It can't be changed on the router, Sir."
It seems to be that response is probably correct as I was not able to find any reference of TKIP or AES in the Linksys E1200 user guide. It appears to be the router does not offer such setting in order to select the specific encryption protocol like other previous Linksys routers offered.
Therefore, it is also possible the computer is taking longer to complete the handshake with the router as it needs to decide whether to use TKIP or AES. One way to figure this out is if you have the chance to test with the connection as opened or unsecured.
I hope this suggestion helps.
Here is what it shows.....thanks.
There is 1 interface on the system:
Name : xxxxxxxxxxxx
Description : Intel(R) Centrino(R) Wireless-N 2230
GUID : xxxxxxxxxxxx
Physical address : xxxxxxxxxxxx
State : connected
SSID : xxxxxxxxxxxx
Network type : Infrastructure
Radio type : 802.11n
Authentication : WPA2-Personal
Cipher : CCMP
Connection mode : Auto Connect
Channel : 1
Receive rate (Mbps) : 144
Transmit rate (Mbps) : 144
Signal : 96%
Profile : xxxxxxxxxxxx
Hosted network status : Not available
The WPA2-Personal is showing in cipher as AES, that's what the CCMP is.
Try WPA-Personal and it should turn back to TKIP but the recieve and transmit rate will drop to 54Mbps)
Try these tweaks....
Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.
Go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.
I have heard to try...(but I cannot confirm this)
Disable Bluetooth on the Centrino 2230 and also set Bluetooth(R) AMP: Disabled.
I had everything to maximum power already so I just went and disabled blue tooth.
Strange that with the older Netgear I had the same thing happen with WPA-2 but WEP connected every time as long as I set it to "up to 150mbs" It wouldn't connect every time with WEP set "up to 54 mbs"
I'll see how this goes for a while then try WPA.
It is interesting to me that's fer sure. I love the notebook and it is incredibly fast with the 3740 i7 and 840 Pro SSD. I cannot hardly believe that it only takes a few minutes to do a virus scan. My other machine with the 2630 i7 and 520 Intel SSD is pretty quick as well.
I will report back after I run it for a while with the iPv6 unchecked.
It just does not like the WPA2. Oh well, that's the way it goes, first your money and then your clothes !
