Re: Yoga 2 Pro Wifi Problems

I have no idea. Check that the contacts inside on the wifi module posts are not touching the inside of the metal case. Other than that, I don't think either Lenovo or Microsoft has any idea. My i7 Yoga 2 Pro works fine, my i5 drops wifi connections regularly - same router, same position in the house. No idea.

This is a potentially dangerous post. First entry from a "user" registered on 8-17-2016 leaving a link to an .exe file?? NO THANKS.

Re: Yoga 2 Pro Wifi Problems

2016-08-17, 21:22 PM

After a very long time of frustration, my wifi dropout on the i5 Yoga 2 Pro was "solved" with a new modem/router.  Here's the story:

My i7 Yoga 2 Pro never drops a connection but my i5 did randomly for over a year.  I replaced the Intel N7260 wifi module with a dual band N7260.  I updated the BIOS.  I tried several different wifi drivers.  I checked wifi module clearance inside the case.

 

The other day my modem/router (Netgear 7550) failed to connect to the internet.  I replaced the modem/router with a new one and that one failed to initialize.  I had used the old power supply cord with the new router, so I changed to the new power supply cord and everything now works normally.

 

Troubleshooting was confused because only the i5 laptop was dropping out and my two desktop machines were stable online.  No thought about the router.  Now that I have changed out both the modem/router AND the power supply cable, I still do not know if the modem/router OR the power supply was the problem.  Since the new modem/router failed to initialize with the old power supply cable, I'd like to think that was the problem.  But since both are now new, I am not going back to analyze which was responsible.

 

Hope this gives someone another idea to pursue.

If your Lenovo Yoga 2 Pro (20266) has Screen Flicker, Shutdown, Sleep, Overheating, Tablet Slow CPU, Yellow Screen, WiFi & BT connection dropping, WiDi (Miracast) fails, Battery Drain Fast and other small issues running with Windows 10. I strongly recommend to read this tested and reliable Setup Guide.

"One thing I realized when I opened the computer is that one of the cables attached to the card was not attached"

 

This was my exact issue.

I hope other will take a look undernear the cover to confirm this before putting a lot of time into troubleshooting this issue.

 

This was not with the YOGA 2, but another Lenovo laptop T580.

I had all the same WiFi-Problems.

Tried everything from driver updates to device manager settings.

I even changed the WiFi-Card and entered into the whitelist problem.

After having the bios modded the problems remained.

 

What finally helped was changing the WiFi-Antennas.

 

No drops in WLAN and Bluetooth anymore.

Wirelessnetview sees more than 50 accesspoint now.

Always expect the unexpected.

@doberstw What did you use for replacement antennas, the same parts or different antennas? Also, where did you get the BIOS mod performed? (Kindly PM me if such info is not allowed to be posted in the forum.)
