JD Rogers, as per http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/g7uj12uc.txt, an update to your BIOS is available (2.58). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything?  If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

Title:
  8086:4238 [Lenovo ThinkPad T430s] iwlwifi using 802.11n associates
  with access point but network is unreachable

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  While the above bug appears to connect and then slow down eventually
  failing with packet loss, my problem is almost the opposite. If I can
  connect, it seems to work fine indefinitely, but initial connections
  (after suspend, or right after a reboot) only occasionally works.
  Sometimes, if I wait long enough the connection starts working after
  several minutes, sometimes it works if I turn off wireless and turn it
  back on, but often it just never works. According to dmesg, iwlwifi is
  associating with the access point just fine, but if I ping the ap, I
  get "netowrk unreachable".

  WORKAROUND: 11n_disable=1

  After associating, dmesg report:
  # dmesg |tail
