Wifi problems with 330S 151KB U

I have a 12 day old 330S 151KBU laptop. I am facing frequent wifi disconnection. When the network comes on again then I get the yellow exclamation mark. At this point I have to reboot the router. When my laptop disconnects or cannot find a wifi network my mobile works fine in the same location. I have read other posts of people having similar problems. Drivers are updated. Windows looks normal (no heavy CPU load etc). Is it a hardware related issue? Lenovo you really have to fix this. Can't believe a machine can't keep a wifi connection. I mean that's a very basic requirement. No heavy technical design problem involved.

Re: Wifi problems with 330S 151KB

I found there  are two kinds of Wi-FI modules in 330S 151KB model because I bought 2 machines recently and used for about 10 days respectively.  One is  from Atheros ( Costco version) , another is from Intel (Bestbuy version).  The model with Intel wifi module has the issue but another is fine.

Re: Wifi problems with 330S 151KB

My laptop has Atheros hardware (for wifi). I checked the drivers carefully and found that it was dated 2017. That is an old version so I downloaded the latest from Lenovo support site (dated October, 2018). Seems to have solved the issue. However the driver I used is for Win 10 1809 but I am running 1803.

Check the driver version. The latest is December, 2018. Windows update might not update the driver.
