X1E (20MFC) battery and wifi

2019-10-06, 11:58 AM

I purchased the laptop approx. 2 months ago. All critical/reccommended updates done through vantage as well as windows.

Although I have tried all tweaks/fixes posted on the forum, these two issues continue to date:

 

/ wifi AC9560

latest driver 21.30.3.2

wifi signal unstable, with several drops and/or speed issues, both on AC and battery. no repeatable pattern of behaviour to date to understand issue.

 

/ battery life

very poor, approx. 4h with full charge, brightness to 50%, just firefox open with 4/5 tabs. tried the unable/re-enable discrete card fix posted here, improved from 2h30 to 4h but still...

 

any pointers on how to solve any of these appreciated.

 

Windows Version: 10.0.18362 Build 18362

 

thx

My only suggestion regarding wifi is to check if your router has the latest firmware update. It takes 2 pieces of equipment to connect and I wouldn't immediately assume it's the laptop card.

 

Based on what you learn about your router there may be settings on the wifi card to help performance.

the reason why I believe the problem lies with this particular card is because I have several other devices that connect with no issues (stable connections and speed). any pointers on the settings/tweaks?

 

thanks on any note

further to the above, event viewer shows:

 

Intel(R) Wireless-AC 9560 160MHz : Has encountered an internal error and has failed.

Intel(R) Wireless-AC 9560 160MHz : Has determined that the network adapter is not functioning properly.

 

hence, not router. I have tried both (latest) drivers by Lenovo and Intel, problem persists.

Do the other devices that connect to your router have the same IDENTICAL wifi card as in your X1E? If not, you're comparing apples to oranges.

Given the latest error messages I'd see if the wifi card is a CRU (customer replaceable unit) and have Lenovo send you a new one.

will do as suggested.

 

regarding your question, no, they are not the same cards. but that would answer the question re: the router.

 

thx

just an update re: wireless card

 

requested replacement card from Lenovo. upon replacement, using as reference Lenovo video, observed that cables main/aux were switched from factory. re-switching correctly made the card working with latest drivers.

 

fyi
