T420: Network Issues

2014-01-09, 3:03 AM

I installed a new hard drive today in my lenovo T420. I installed Windows 7 ultimate, but it won't recognize the internal network card. I can't find the driver anywhere, and when I try to download any kind of driver that I think would help, When i hit f5, it responds with "no network adapter found" and it also doesn't show up under computer management. I'm using a USB adapter right now, but I would like the internal card to work. Also, when I tried to install the bluetooth adapter driver, it told me that the installation couldn't complete because there was no supportable hardware. I really need help on this!


I am very tech savvy, I built my own PC and run a technology repair company, but I typically don't work with software, mainly hardware. I still know my way around, so don't be afraid to get technical when helping and don't use the cliche "have you tried turning it off and back on" answer please:)


Thanks again!

Welcome to Lenovo Community Forums!


I’m sorry to hear that network adapter is not getting detected in your Lenovo ThinkPad T420.


Check in BIOS -> Security -> I/O port access if network adapter is enabled.


Hope this helps!


Best regards,
