Welcome to the Forums.
From page 99 of the B50-70 hardware maintenance manual, you can opt to use these dual band cards:
Intel 3160 1x1AC+BT PCIE (NGFF WLAN), FRU#: 20200418
Intel 7260 2x2AC+BT PCIE M.2 WLAN V2, FRU#: 20200552
Intel 7265 2x2AC+BT PCIE M.2 WLAN, FRU#: 20200609
Cbt (Broadcom) BCM4352 2x2AC+BT4.0 PCIE M.2 WLAN, FRU#: 20200480
You can mostly find these parts on sale online (eg., Ebay)

I don't have a B50-70 unit here for testing but AFAIK, as long as it's a lenovo FRU and it's on the supported WLAN card list (page 99 of the B50-70 HMM), it should work especially if it was taken out from another lenovo unit (eg., Y50-70).
All of the cards listed above are on the B50-70 supported WLAN list.

Here another user trying to buy a wifi card. The current RTL8723BE doesnt works correctly. Does someone find anywhere a shop to get the white list cards?
Support from Lenovo says that they can not provide support of third party parts (!!!!) . I'm very angry with that...
Please, if you find a vendor post it. BTW, if you have tried with LInux comment if it works fine.
