![]() WhoIsConnectedSniffer is a network discovery tool that listens to network packets on your network adapter using a capture driver (WinpCap or MS network monitor) and accumulates a list of computer and devices currently connected to your network. You can find the meaning of these codes in this Web page.Īdded 'Association Requests' column, which displays the number of association requests sent by the client. These columns might be useful to disgnose wifi connection problems. ![]() Hopefully, this change will solve the 'Failed to load the NmApi.dll file' error that occurred on some systems.Īdded 'Association Status Code' and 'Deauthentication Code' columns. WifiChannelMonitor now tries to load the NmApi.dll file according to the installation path specified in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Netmon3. ![]() WifiChannelMonitor also allows you to view the information about wifi clients that are not connected to any access points, including the list of SSIDs (network names) that they are trying to connect.įor every access point, the following information is displayed: SSID, MAC Address, Device Manufacturer, PHY Type, Channel, RSSI, Security, Beacons Count, Probe Responses Count, Data Bytes, Retransmitted Data Bytes, and more.įor every client, the following information is displayed: MAC Address, Device Manufacturer, SSID list that the client tries to connect, Sent Data Bytes, Received Data Bytes, Probe Requests Count, and more. But if you can manage a PC network then you shouldn't have much trouble, and what you'll get for your efforts is one of the most capable and configurable free web filters around.WifiChannelMonitor captures wifi traffic on the channel you choose, using Microsoft Network Monitor capture driver in monitor mode, and displays extensive information about access points and the wifi clients connected to them. NxFilter is an enterprise-level web filter, and setting it up needs some network experience, and a little time. If the default site blocking isn't enough, NxFilter supports adding domains manually, or grabbing the blacklist from You get a stack of configuration options, there's even support for authenticating users via LDAP and Active Directory (as well as password and IP address), all while delivering great performance (the developer claims NxFilter can handle "several thousands of users easily"). And you're even able to assign policies based on a time range, so for example an office might have a very loose policy at lunchtime, but something much more restrictive for the rest of the day. ![]() These policies can be applied to individual network users, or groups of users. If you need more control, it's possible to create NxFilter policies which block sites by category (75 in total), or only allow access to particular site categories - or all internet access - for a certain amount of time a day. A browser-based console displays stats on web traffic, blocked domains and more, as well as logging every site you've accessed. Get NxFilter running on one PC, though, and it brings benefits right away, blocking known phishing sites and using packet inspection to detect some malware. It's still not difficult - if you know how to configure your system to use a custom DNS server then you won't have much trouble - but you will have a little work to do. NxFilter isn't for network beginners, it won't fully set up everything itself, and even the web tutorial doesn't walk you through every detail. You'll first need to install and configure the program, of course, and that can take a little effort. It's also possible to limit access by user and time, and one NxFilter installation can protect your entire network. NxFilter is a powerful Java-based web filter which controls access to web sites based on their domain names.
