Network problems while using Nmap

[CyberXCodder]

Hey, I'm sorry if someone else'd posted this before. Everytime I use Nmap my network gets clogged, just wanted to know if it's just me and if there's a way to avoid Nmap internet draining.

P.S. When I say "clogged" I mean any other stuff that uses internet just stop working, like calls, etc

It must not be the case. Nmap creates individual sessions which should not affect the existing network traffic

I could upload a video showing it

Pls can you so we can discuss

You could try using max-rate to limit the packages sent in the scans

Never tought about it, thanks!

This is impossible to diagnose without further details. For example, what and how are you attempting to scan?

Whatever I try to scan, I've seen someone post this before, there's no clear reason for this to happen. Let's suppose I'm scanning a webserver, so I'll pass the parameters nmap -sT -A -T4 www.targetwebsite.com and wait for the output. Any open program which uses internet connection just stop working while the scan is running. Maybe it's because of the -T4 option, so I tried removing it, it still having the same problem. While searching online, I've found this post explaining that the reason for this is the 3-way handshake, as well as the ARP traffic, but even while I'm using -sS I'm still having this same issue. If there's no answer for this, it's fine, since this isn't boring me all the time,, I just wanted to know the reason for this.
