Problem:

Since this afternoon, xfinity drops my lenovo yoga 2 laptop Wifi connection frequently. My laptop keeps reconnecting to the xfinity every 10 seconds.

Process:

First I suspected there are some problems with my laptop internet card driver, since my other device, smartphone and ipad, all works fine.

I followed the steps in this Lenovo support forum, but it doesn’t work. https://support.lenovo.com/us/en/solutions/ht502846

And I also tried to update the drive for my internet card Qualcomm Atheros QCA61x4 via Driver Easy Free Edition. It still doesn’t work.

Then I recalled once a while, my phone switched to connect to xfinity open wifi when it’s in my home. It might be some problem with my xifinity gateway.

Solution:

First, follow the steps in this post to see if it can fix your problem.

If not, (it didn’t work for me), open the admin page of your gateway at http://10.0.0.1 . Default username and password is admin, password. And enter gateway->connection->wifi , then use different names for 5G channel and 2.4G channel.

Using the same name for both 2.4G and 5G channels might make your device to keep dropping from the wifi.
