Dos Attacks on NightHawk AC3200 Model C7800
We are having so many problems with our new router. Looking at the Log I see this DOS Attacks: [DoS attack: Echo char gen] from source: 83.97.20.35, port 51723, Thu, May 07, 2020 21:17:03 [DoS a...
So many questions.....
When you log into your router, 192.168.1.1. admin and password. Didyou change the password to something other than password?
Does Cox require login via the router?
Is your DNS auto?
Do you require Static IP?
Is your WiFi locked down and protected. Even the GUEST network?!
Gamer? (Xbox? PS3/4?.Etc)
Are you using port forwarding?
Do your PC's that use the internet have malware or virus on them?
Thanks for offering to help. I'm answering your questions.
1. No we didn't change the password.2. I don't know if Cox requires a login.
3. We are setup with DHCP
4. I don't know if I require a static IP5. The Guest Network is not enabled. I'm not sure if Wifi is locked down.
How would I know?
6. We are not gamers.
7. Port forwarding is turned off8. I just found out I had a virus but I've cleaned it up. The other 2 laptops doesnot have viruses. We use BitDefender and Malwarebytes on 2 laptops and work laptop has crowdstrike.
Ok. Here is some more
1. No we didn't change the password.
**Log into the router on PC with 192.168.1.1. admin/password. Click on the advance tab. Go to admin tab on the right. Click set password. Your old password will be password. Then make a new one that you can remember. This will be how you log into the router from 192.168.1.1. User name will still be admin and the passowrd will be your new on
2. I don't know if Cox requires a login.
**From what I can see online, they do not.
3. We are setup with DHCP
**Good
4. I don't know if I require a static IP**On log in page, 192.168.1.1, under the internet tab there should be the option of Internet IP Address. Most ISP are Get Dynamically from ISP. If the other is checked, call Cox and see what they require.
5. The Guest Network is not enabled.
**On the log in page of you router, 192.168.1.1, there should be a tab called Guest Network. Make sure that it isn't broadcasting. But just in case, give it an SSID. I put one in with "=" and "*" and weird symbols. Then I gave it a security option. Last I have it a password miles long. (This isn't one you need to remember if you will never use Guest Network.
6. I'm not sure if Wifi is locked down. How would I know?
** One the log in page, 192.168.1.1, there should be a tab called Wireless. Here you will give your network a(n) SSID. Next pick your security level. (This is your preference). Then choose to broadcast or not. Some people do and some don't. Pick a passowrd that uses special symbols with numbers and letter and caps. Example: !PaSS!word?IsSAFE!05072020*!
7. We are not gamers.** OK
8. Port forwarding is turned off**OK
9. I just found out I had a virus but I've cleaned it up. The other 2 laptops doesnot have viruses. We use BitDefender and Malwarebytes on 2 laptops and work laptop has crowdstrike.
**Use malware to do a DEEP scan on your machines to make sure there are no lingering malware. Also, if you havent already, do a right click update on Malware. All my machines had an update today.
Do you rent a modem from Cox? Is your modem from Cox a 2 in 1? Example, it is a modem and router in one unit. If that is the case, then you just need Cox to go into their setting and turn off the WiFi and allow your router to be primary.
I know this seems like a lot but this should take 10-15 minutes to do. Last, when your router is updated and everything is complete. Reboot the modem and router.
