Frequent loss of internet connection - DNS problems
Hi lately I've been having problems with my internet connection. I would often disconnect and get the error: "DNS_PROBE_FINISHED_NO_INTERNET". The wifi icon goes to the one with the yellow warning arrow. Im currently running widows 10. And my wifi adaptor is qualcomm atheros qca61x4a. Its a new laptop, just over 2 weeks old and I have tried updating drivers and scanning my computer with windows defender.
I loose connection maybe every 30min.
Its really annoying and is driving me crazy.
Also its only my laptop with the problems, my old one is fine
EDIT - My laptop is the Lenovo E570

Do you have any other wireless devices that have the same issue?
The problem with wireless is that it's not as simple to troubleshoot.
This is what I would like to confirm.
When the connection is good, go to a command prompt (right click on start menu and choose command prompt admin mode) and type in:
IPCONFIG /ALL
Notate the IPV4 address, default gateway, and Preferred IPV4 DNS server.
When the disconnect happens, rerun the command and compare the two.
Please forgive spelling and misworded errors. My phone likes to autocorrect a lot.
