Back on the 8th of August we talked about a WiFi issue with our Lenovo U310 Ultrabook. The range and speed were not up to par with other devices using the same access point. After our story on the 8th, Mark, an admin from the Lenovo support forums, responded to indicate that Lenovo had nailed down the problem which was affecting U310 and U410 units. Mark explained that U310 and U410 units manufactured before July 23rd had the issue which would require servicing to fix. Lenovo and retailers seem to be still selling units manufactured before July 23rd.
