Ping in cmd. Packets are always lost no matter timeout value

So, for months I have been having lags randomly in games or internet.
I AM SURE THAT THE PROBLEM IS IN THE ROUTER OR ISP (but I hope it’s in the router). I only used wireless, never tried to connect router using a cable.
Sometimes downloads starts at 3 kbp/s and there’s nothing I can do to change it UNLESS I restart it. If so, it will then come at full speed. This occurs often.
But I’m trying to fix it and to begin i’m testing to ping google in cmd.
I realized that in 20 tries, about 1-2 packets are lost, even setting timeout value to 5 minutes.
How come?
Any ideas?
Thanks
Answer #1
Are you sure there aren’t any anti-virus or firewall software messing with the connection?
Answer #2
No, it’s not.
Answer #3
about 1-2 packets are lost
this happen if you ping your router or your ISP, or just happen when your ping a site
it drop packets when pinging major sites (say google or micro$oft)
might be a problem with your MTU size (Maximum Transmission Unit)
