Wi-Fi protection

[rsn 135]

It is more likely someone that has a device set to auto connect with auto retry. In that event it isn't a DoS attack but some idiot that doesn't know how to set up his system. That is why I suggested they allow them to connect so they can see who it is. At that point he can turn his security back on and go confront the other person.

The situation you described above would not cause any noticeable issues on a network.

Hey guys, After we have set up our wireless internet to be able to connect our Nintendo Wii, and Kindle. Now I found out that there's an attacker sending DoS Attack (Denial-of-service attack) on our network on purpose to prevent us from using our own service, what should we do to prevent such attack from appearing on our wireless router logs. Everyday we see this attack recorded.

Anyone with that has experienced similar situation? Any advice will be very helpful.

As long as you have WPA encryption and a simple NAT firewall, you will be fine on most home networks.

Then he has some L33T hacker with an attitude. I would still bet that if he turned off his protection for a moment the bad guy would connect in an attempt to do some other "L33T" things. He would at least have the bad guys IP if not the name of the computer.

Unless he is positive that this perceived threat is causing real problems on his network, he should do nothing and let the router do its job. It is common for router logs to list daily attempted "attacks". This is not something to worry about, again, unless there is proof that this is directly affecting performance.

Thank you everyone for your prompt reply, we have Wi-Fi security enable, SSID isn't turned off, we have passphrase, WPA2 enable, but everyday our Router logs is bombarded with connection rejected messages, DoS Attacks, its becoming worry some. We have symantec Norton anti-virus. The panic came when I read about the harm this attack may cause.

[repeat for emphasis]

change your SSID name, change it also to 'not broadcast' (this bit is important)

then pick a compatible encryption type.

Then, back at each device, manually enter the new SSID name and encryption key.

Good LUCK !

I'm sorry, but you are wrong. Read my post about disabling SSID broadcasts above. Do not disable SSID broadcast - this is bad advice as it may lead to connection issues and provides no security benefits. You are regurgitating an old wives tale without any knowledge of the consequences of this action.

It hasn't even been established that someone making a Wi-Fi connection is causing the problems.

If the suspected DoS attack is targeting his public IP address then more than likely it has nothing to do with the Wi-Fi network.

Contact your ISP Tech Support and explain the situation. They should be able to kill your IP Lease in which case after rebooting your modem you'll have a new IP address. If the problem stops then that was it.
