This paper brings forth a distributed self adaptive intrusion detection system (IDS) based on programmable mobile agents which can act as a key line of defense against major security attacks. The proposed intrusion detection model is organized as a combination of the two trends in IDS; the rule based and the behavior based scheme. Also this model draws out the…
Plug your computer to router with LAN, if LAN speedtest same speed as wifi then no need for wifi upgrade. This solution is only valid if all you need your wifi connection for is to route traffic from the internet to your computer. If that s the case, then this will show if you have any speed degradation once the packets hit your network. If that s all you re…
