I accepted to upgrade android v5.0.1 in my lenovo tablette yoga 2 1050F and now it's impossible to connect my wifi network, I still use a WEP key. It worked fine before the upgrade and all my computers and other tablette work fine too.
I also tried to re-enter my key several time, I did a factory reset but nothing works.
So What can I do ?
Thank you for your help

I have the exact same problem as you. I upgraded to Android v5.0 because I got notified and that was great.. but as soon as I tried to connect to my home WiFI, it only comes up with the following..
1) Saved, until you click connect. Stays the same for about 30seconds-1 minute
2) Worst of all, I hate this. It says Authentication problem and that's all. You can try everything from factory resetting, deleting/forgetting the network.. nothing works!
It's horrible and nerveracking as I can't find a simple quickfix for this. I want to be upgraded to the latest OS and not be just be stuck on 4.4.2.
I connected to a hotspot set up on my Windows PC using a downloadable application called Connectify which I have set just connecting to my normal network that I'd use (the one I can't get the tablet to connect to) and the tablet has no problem connecting to that. My modem is on channel 4 and always has been since it was installed as it has never been changed. I can connect to my network fine with any other device that I own, but not my tablet. I had no issues while the tablet runned on 4.4.2 but now I have no connection to my normal network and I'm forced to use a hotspot to access the internet.
Okay - people might see this as a temporary fix but the thought of your tablet not being able to connect to your network (something that it's supposed to), is a major let down. Of course, this is not the tablet's fault. It's the new update and apparently it's full of glitches and problems.
I'll let you know if I find any fixes for me.

Well it is an old and unsecure encriprion, that is rarely used anymore, maybe they dropped saupport for it. Of course it could be just a bug. But changing the encryption wont hurt anyways.

Lenovo is investigating customer reports that Wi-Fi via WEP is unsupported. I was able to confirm with the development team that WEP is supported on Yoga Tablet 2 devices running Lollipop.
It would help the investigation if several customers would be willing to provide logs capturing this failure event for Yoga Tablet 2 8 or 10 1050 models.
To capture logs, please follow this procedure: http://support.lenovo.com/us/en/products/tablets/yoga-series/yoga-tablet-2-830/documents/HT103449
Once you have collected the logs, please zip the files and attach them to an email which can then be sent to firstname.lastname@example.org. If the file is too large to send, please provide a link to the hosted file.
With the email, please include the following information:
Forums User ID:
A description of the failure and any other information you would like to share:

Once I receive customer logs, I will open a case to escalate these reports for a solution.

I don't understand much, but is it possible, that the device is working in 802.11n mode only, where WEP is not supported?
Btw, just tested, I am connecting perfectly to WEP incripted network at home.
-EDIT2- I don't know why this post is marked as solution.

It's really annoying though, upgrading to a new version of Android. You don't expect problems like this to happen and now I'm pretty much stuck with a tablet that can connect to WiFi, but not mine.
Here's some of the details that my computer tells me.

I've just sent logs to address forumspi.
My problem: I cannot connect to my home wifi when it's running in 802.11n ONLY mode. While in mixed mode (802.11 b/g/n) my 1050L is connecting in 802.11g mode.
