Can't see 5GHz wifi on Lenovo Yoga 1st gen anymore

Here is my situation (read carefully):

 

I never had wifi problems with my 1st gen Lenovo Yoga running Windows 8 64-bit.

 

Always super fast wifi and 5 bars on the icon.

 

One morning, I couldn't connect to my home wifi (unidentified network), but I had no problem on my Android phone.

 

I called my Internet provider and they "separated" the 2.4GHz channel (made for further distances, but slower) and the 5GHz channel (for shorter distances, faster).

 

From then on, I could see the 2.4GHz on my laptop, but not connect to it and I couldn't see the 5GHz.

On my phone, I could see both.

 

As I obviously suspected a problem with the Realtek RTL8723A network adapter on my laptop, I reinstalled the driver, which partly solved the problem, as I can now surf the Internet on the 2.4GHz, but still can't see the 5GHz.

Plus, I only have 1 bar on the icon, even though I'm 2m from the router.

 

Is there anything I could do to see both channels, just like on my phone, and be able to use the faster 5GHz channel?

 

Thanks

Try rebooting your modem and router.

Hello Duderino

Thanks for using the Lenovo forums.


Sounds like your adapter is not compatible with 5GHz wifi channel, this is more than likely the cause of it only being able to see the 2.4GHz signal.

 

This may help

 

Hope this helps, let us know how you get on.
