[Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]
Hello,
I have the same problem on my Lenovo Flex 2-14.
I tried the tip #38 and it seems to be a little more stable. But the
drop outs are existent in present and the pingrate to my local router is
very slow.
Another problem is that i'm not able to find or connect with another
bluetoothdevice with this notebook. I'm not sure if that fact is in
relationship with the wifi-problem.
Here are my additional parameters:
