Lenovo Yoga Pro 2 wifi network driver problem

[johnnyathan]

So one day while trying to do my homework I tried to connect to the wifi at my house. Suddenly I couldn't connect nor could I see the connections with any networks. My computer gave me a message saying "Not connected - no connections available". When I troubleshooted the issue it gave me a message stating "Windows could not find a driver for your network adapter". So I used a flash drive and a classmates computer to install the latest driver and bios on my Lenovo Yoga. The next day my computer gave me a message saying "Windows did not detect a properly installed network adapter. If you have a network adapter you will need to re-install the driver." I really need to fix this problem and this is finals week. Please help!

Take a look in Device Manager for any possible clues as to the wireless adapter's current status, don't just take a blind guess and start installing things, especially potentially risky stuff like a BIOS update. You must learn to investigate more before you act!

Phillip,

I got this router Linksys EAC6400 from Cisco... This is a dual-band router, it has 2GHh and 5GHz so it emulates the 1st and the 2nd network (this is on Windows 8 on Yoga2, it shows SID, I connect it to the SID, and in the task bar it shows SID 2..., on my Lenovo G580 on Linux Mint, it shows SID, I connect it to the SID and it shows SID, like normal behavior).
Now the issue here with Yoga2 is the following:
- at the time I bought it, I had a draft 802.11n router, so I powered it on, it installed that OS... windows 8;
- while having that draft 802.11n router, the connection went well;
- replaced the 802.11n draft router with the Cisco EAC6400 and now the connection on Yoga2 drops (while on Lenovo G580 works perfectly);
- tried Linux Mint on Yoga2 and the connection was ok, didn't drop;
- performed a BIOS update on Yoga2 and now the connection seems to be ok;

Now based on your assumption, this seems to be a BIOS issue, the way that Yoga2's previous / initial BIOS handles the Wi-Fi device is faulty.
We'll see...

Thanks.

UPDATE: Windows sucks! It still drops the connection and says 'Limited', trying to re-connect says 'Cannot connect to this network'.

ANOTHER UPDATE: I have linked the draft N router to the EAC6400 so now I got 802.11n and 802.11ac/n. Guess what? Windows DOESN'T SEE the SID of 802.11n! I'm going to configure both routers to use different channels (not on Auto, even though the 802.11n has this ARP isolation check box checked!!!). Unbelievable!!!
