I need help with not lagging out when spoofing. I’ve tried spoofing first then sniffing and vice versa but I still lag out. I cancel the run early and I still lag out. The only way I won’t lag out is if I start it and stop it almost simultaneously but I don’t get ip’s. This only happens on my router at my dad’s. It may be because the bandwidth is being used up by my neighborhood due to staying at home. If there is a solution that you guys could help with it would be great.
