Do you have problems with your wifi?
- reificator 7y agoI had problems on my Yoga 730, replaced the Wifi chip with one that was under $20 on Amazon, never messed with drivers or anything, and it's been working great for years now.
- Mo3 7y agoNo. Only on Linux, which requires the default ideapad drivers to be removed and rtl8821ce to be used.
- XMPPwocky 7y agoAFAIK the wifi problem (in the case of the device I looked at, that manifested as constant wifi drops unless the laptop was plugged in (frequent enough to make it essentially unusable)) is just sort of a ...thing that one particular model of defective Wi-Fi card will do. IIRC it's a Realtek card. It seems like a software or driver problem, but no software fix seemed to work. Only replacement with https://www.amazon.com/gp/product/B079QH5KW1/ https://www.amazon.com/gp/product/B079QH5KW1/ solved the issue.
- cjbprime 7y agoHuh, that's interesting. I once worked for a laptop manufacturer, and the inverse problem (wifi only working when on battery) happened there -- it was an issue of high frequency electronic shielding off the power supplies. Something about how the modern auto-layout PCB software the ODM wanted to use had no way to take shielding issues into account and would want to lay traces in routes that an electrical engineer would never even consider. I can't think how the inverse problem would happen, though. Maybe it's software indeed.
