Here are some outputs:

root@debian:/home/love# iwconfig wlan0

          Retry short limit:7   RTS thr=2347 B   Fragment thr:off
          Encryption key:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

I noticed the value increases with time and my wifi stay connected but internet stop working.

    That looks like a typical wifi interference problem. Try to locate the device causing the issue and when you do, delete this question as it would be off-topic. Simply turning most electronic equipment off and paying attention to what changes when the problems start can usually solve 90% of these. – Julie Pelletier Jan 15 '17 at 4:47
  • I have netgear external wifi adaptor, It worked fine with windows but when I had Debian it had similar problem, Now I installed kali linux (and it doesn't require me to install its drivers) It has same problem. – Love Grover Jan 15 '17 at 4:55
  • Can you still try it on Windows to see if the situation may have changed? – Julie Pelletier Jan 15 '17 at 5:22
  • My situation sees over 1M invalid packets. Yes, it's that noisy here, and I can't switch to 5G. – Gene Apr 25 '17 at 13:21

    I'm seeing this with my Intel 8260 adapter. What is frustrating is that all I can see is this high-level error count. How can I see the actual errors that my adapter is emitting in a log? – Jesse Adelman Nov 3 '18 at 16:36
