Randomly losing internet for a few seconds.

[Yukari The Alpaca]

I randomly lose internet for a few seconds. It does not disconnect me from the network but for a few seconds I suddenly see my discord say “voice disconnected” and my games/browser come to a halt. I have already tried rebooting the router and full-on resetting it. Nothing seems to work. I have already tried switching cables and unplugging and everything. I cannot view my system logs. It tells me to try again every time. Is my router infected? In the firewall logs, I see this:

FW.IPv6 INPUT drop , 24 Attempts, 2018/2/27 10:28:19 Firewall Blocked
FW.IPv6 FORWARD drop , 307 Attempts, 2018/2/27 10:25:12 Firewall Blocked

Anyone know what is going on? I can’t tell if it’s my router or not. I ran some scans and no malware came up on my pc.

If you know the IP of your router (find the Default Gateway of your network by using ipconfig in the command prompt) you can run a ping request to it from the command prompt and then let the ping run in (such as this example):

ping 192.168.1.1 -t

You can then open a second command prompt window and ping an outside location such as google's DNS server of 8.8.8.8 and do it as such:

ping 8.8.8.8 -t

Leave these two command prompt windows open and the next time your internet has some kind of hiccup, look at both.

If ONLY your ping to the DNS server stops, then the issue has to do with the modem and/or connection from your router to the modem and/or outside connection beyond your control.
If your ping to the router stops, then the issue lies somewhere between your PC and the router.

You need to try and narrow the problematic area down so you're not trying to troubleshoot everything.

I already tested something similar. My phone also stops loading things that require an internet connection during the hiccup. I think it is the router. It is an all-in-one so I can’t just replace one part. Back to comcast it goes.

Still doesn't isolate whether it is between your devices (phone//pc) and the modem/router or your modem/router to the outside world.

Try...

-Right click on the wifi icon, "Open Network and Sharing Center"
-Left hand side "Change Adapter Settings"
-Right click on your hardware "Properties"
-Click "Configure"
-On the Power Management Tab uncheck "Allow the computer to turn off this device to save battery"

Your router is claiming drops, which could be via power management.

I am just going to send the router back and get a new one. It’s free so I don’t care too much about replacing it. Let’s see if that fixes it.

I disable everything except IPv4. I doubt you need IPv6 but I also doubt that is the core issue here.

I don’t know if ipv6 is the problem, but I currently cannot fix the issue since I no longer have the router and need to get a replacement. Hopefully that will solve the issue.

IPV6 would only be a problem if your router used it by default.

It does and I cannot turn it off.

Yes for Internet all you require is IPv4
Go into the actual Network Adapter in the OS and uncehck the box for IPv6 and click OK
Then do a FlushDNS on that PC.

To make a Flush easier to do; make a new TXT file and put this text inside


ipconfig /release
pause
ipconfig /renew
pause
netsh winsock reset catalog
pause
netsh int ipv4 reset
pause
netsh int ipv6 reset
pause
ipconfig /flushdns
pause
netsh int ip reset reset.log
pause


Save the TXT file, then change the .TXT to .BAT
Now double click the new BAT file to run it.
You need to be able to see File Extensions in your OS.
You can enable this in "Folder Options"

THE BELOW APPLIES TO WIRED AND WiFi

Try pining your modem 100 times. Open a command prompt and type:

IPCONFIG

Find Default IPv4 Gateway and plug that address (should begin with 192.168.xxx.xx) into this in the command prompt:

PING -n 100 192.168.xxx.xx

If you get packet loss to your router, it's on your end. If you don't get packet loss, try it a few more times just to make sure.

THIS PART APPLIES TO WiFi ONLY. You mention cables so not sure, but going to leave this here anyway.

I've had similar problems earlier this year and it came down to a crowded 2.4Ghz band. I had to upgrade to a dual-band modem and switch to 5Ghz.

Download Wifi Analyzer and check to see if you're being crowded out.
