Wi-Fi issues persist even after a complete reinstall on Windows.
i meant i never mentioned sdio came from majorgeeks, just shared the link so he could get familiar with it if needed. first, i think you're correct about windows not having the latest drivers unless you use a Windows update. second, if he doesn't require sdio, perhaps suggest alternatives instead of criticizing my post. third, consider sdio to check if other devices need updates that might affect his wifi driver. outdated drivers can cause problems, so i try to assist. by the way, if an update fails, try adjusting the power settings of the wifi adapter and the default windows power mode. iobit driver booster pro offered more updates than sdio, though it's not free, which is why i didn't suggest it. the free version might have more options.
I had just done some research, and it would appear that the OP has either a Qualcomm Atheros QCNFA335 or QCNFA345, both of which are M.2 cards, based upon Lenovo's hardware maintenance document. I think that the drivers installed were not Qualcomm/Atheros's drivers, but rather Microsoft drivers, the ones that are preinstalled in the image. @duncannah , try using SDIO (Driver Booster is also an option, as @DukeJukem, however SDIO does not require installation, so you do not have to worry about rogue registry keys staying behind (I have to admit though, Driver Booster's uninstallation is very clean, only leaving one registry key behind), as well as not having to worry about the drivers staying in your temporary files (SDIO's driver packs and indexes are located in "drivers" and "indexes", respectively, within SDIO's main folder). One last thing, though. If this is a hardware issue (probably not, however we have seen wireless cards dying at the repair lab I work at), my recommendation to get an Intel Wireless-AC 9260, is not a good idea for your, as I had forgotten about Lenovo's WiFi whitelist habits (which it may be possible that they had finally left, I was shocked that my laptop, the IdeaPad 300-15ISK, does not have one, and this is after flashing updated firmware, which was released about 1.5-2 years before the Intel 9260 was released)), unless you are willing to modify your firmware (you can find help aver at Bios Mods , I'll be doing so soon, and in the future, I hope to build CoreBoot for my laptop). In such a case, a better idea will be to get the Intel Wireless-AC 8260, for about the same price as the 9260, again from China (I recommend Fenvi, which have stores on both AliExpress and Amazon due to their great customer support (though I have only bought from their AliExpress store, due to Amazon not officially supporting my country (I'm not going to pay more money for shipping than the cost of the product), and updating your firmware to the latest version found on Lenovo's website (the firmware was updated a bit after the 8260 was released, so it will definitely be in the whitelist). In any case, upgrading the wireless card will improve your laptop's wireless performance (you have a 1x1 card, not sure whether it is N or AC, and Bluetooth 4.0, and the Intel 8260 is a 2x2 AC card, with BT4.2), so I heartily recommend it.
