Feedback on the Lenovo X201 (Type 3249-CTO)

Asked by Greg

Reporting it seems Lenovo have changed the wireless card in these laptops. The X201 we have here has a Realtek card in it (not the Intel Centrino card stated on the certification page) and uses the wireless driver rtlwifi (instead of iwlwifi). This driver does not work consistently with the laptop and tends to drop the wireless connection after a while then refuse to reconnect again without restarting the Realtek modules. This post almost exactly describes the problem with the latest Lenovo ThinkPad X201:

As you noticed, the certified model comes with the Centrino-N card, not the realtek. I own one of the older x201's myself (and it has it's own special issues with wireless). Unfortunately, we don't really support non-certified hardware, but I do encourage you to read the attached FAQ and file a bug, providing as much detail as you can (including links like the one you provided here).
FAQ #2145: “My certified system has hardware that doesn't work”.

Can you help with this problem?

Provide an answer of your own, or ask Greg for more information if necessary.
