DoS on HotSpot

Hello, Help! How do I stop this? its flooding my hosts and by doing so blocking us to access the internet no diff than a DoS or maybe a Syn flood attack. I added filter rules for syn flood attack but it wont do anything.

maybe you had this experience, I really really need to fix this like, right now!

“Hosts” in my hotspot are flooding my router & no users or me can access the internet. Users who have not logged in or authenticated yet. but this appears they are hosing it up with a combined force like a DoS attack and my HotSpot basically crippled and my machine out of commission.

How do I STOP this now. I am just basically attacked and nothing from my server can come out. is there anything I can add on the firewall chain forward to drop them?
Thank you.

Where are you seeing a DoS? There is no traffic beyond background noise in your screenshot.

SYN FLOOD !!! been resolved !!
