Lenovo B590 configuration or hardware problems (microphone and WAN miniport)?

Question

Hi,
First message here. :-)
Ok, when I use the integrated microphone, I can barely hear myself. It has always worked like that and I don't know if there's a problem. I uninstalled and installed the drivers, I amplified +20 dB and the output is very low. When I'm trying out different things, if I try to configure speech recognition and read the sentence I can see how the bar oscillates like it recognizes some sound, but the result is too low and it tells me that it couldn't hear a thing.
Also, out of nothing I receive this message that tells me that my WAN miniport is disabled. The Lenovo Solution Center detects this problem but it doesn't fix it, and I can't enable The WAN miniport it in the device administrator, either.
Thank you for your help.
Solved!

Hi EXinthenet, welcome to the forums,
regarding the WAN Miniport, it seems that a recent Microsoft update (KB2836988) has caused this to happen on some systems, unfortunately uninstalling the update doesn't solve the problem.
You could do a system restore in Windows to a point before the update was installed and then whan you update hide / exclude the update by right clicking it before updating.  More information and an alternative fix can be found in the following threads,

I would suggest starting another thread for the microphone issue, don't forget to state which operating system version, 32 bit / 64 bit, and sound driver versions you have installed.
