currently I run on my Lenovo S430 using a the Intel Centrino Wireless-N 2230 with latest Intel drivers.
The funny point is, that only this wireless card do not see this Wifi given from Technicolor Inc. USA.
Screen shot from an older Lenovo U450p with WifiInfoView, where all is OK...
I am sorry you are having problems with the system but let me help you.
Based on your description I would like you to do some troubleshooting steps:
did a bios update without any changes,
I use Win 7 Pro ENG all updates and uninstalled all drivers and now using the Intel driver set 17.0.1 without success...
Simple connecting a Cisco USB LynkSys AE6300 on the same laptop works like a charm
Would you confirm the Intel driver version? Did you mean 17.0.1 or 17.1.0?
There is a new version of PROSet & drivers you might try: PROSet version 17.1.0, which has updated 188.8.131.52 drivers for the 2230 on Windows 7.
The previous version of PROSet for the 2230 adapter was 16.11.0, and that software package came with 15.11 drivers for Windows 7.
Have you tried using the previous version of PROSet (16.11.0 PROSet with 184.108.40.206 drivers for Windows 7)? Did you get the same behavior as you do with the very latest software package?
I was upgrading from a previous Intel driver (but do not ask me the version), while it was not working at all...
in other words there was not any valid connection with this wifi router yet.
Is TKIP your only option for encryption (cipher)? Can you try connect using WPA2/AES encryption instead of TKIP? Are you connecting to a home network or is this connect at work or at a business?
Security is currently WPA-PSK + WPA2-PSK, Cipher is TKIP + CCMP... is see other WifI only have WPA2-PSK & CCMP
Currently I do not have to password for login... stay tuned..
