Lenovo B590 5Ghz WiFi Support

2018-11-15, 12:29 PM

I am trying to find out if I can upgrade my wifi card to support 5Ghz networks on an B590?  Can anyone confirm this is possible and if so what NIC I need to install?

Hi michaelspitz! Welcome to Community Forums.

I've checked the machine information, 11b/g/n type of wifi card (2.4 ghz) is the only one used for this model. I'm afraid we cannot guarantee if 11n or 11ac wifi cards (2.4/5 ghz) will work because it's not yet certified under the parts list. You may check the hardware manual https://download.lenovo.com/pccbbs/mobiles_pdf/b590_hmm_en.pdf for your reference, turn to page 84. Hope this answer your query.

If the listed parts do not contain an AC type card, an aftermarket card will not work and will actually prevent the system from booting into windows.

As with other system manufactures (Dell, HP and others) Lenovo systems have a "White List" contained in BIOS of accepted parts, and if a part is installed that is not on that list it will not allow the system to boot up.
