Network Analyzer can help you diagnose various problems in your wifi network setup, Internet connectivity, and also detect various issues on remote servers thanks to the wide range of tools it provides.
 
It is equipped with a fast wifi device discovery tool, including all the LAN device's addresses, manufacturers and names, together with the Bonjour/DLNA services they provide. Further, Network Analyzer contains standard net diagnostic tools such as ping, traceroute, port scanner, DNS lookup, whois, and network speed test. Finally, it shows all neighbouring wi-fi networks together with additional details such as signal strength, encryption and router manufacturer to help discovering the best channel for a wireless router. Everything works with both IPv4 and IPv6.


Wifi signal meter:
- Both graphical and textual representation showing network channels and signal strengths
- Channel usage graph - see per-channel utilization
- Wifi network type (WEP, WPA, WPA2)
- Wifi encryption (AES, TKIP)
- BSSID (router MAC address), manufacturer, WPS support
- Bandwidth (Android 6 and newer only)

LAN scanner:
- Fast and reliable detection of all network devices
- Vendor name, IP, and MAC addresses of all discovered devices 
- NetBIOS, mDNS (bonjour), LLMNR, and DNS name where available 
- Pingability test of discovered devices
- IPv6 availability and discovered IPv6 addresses
- Wake on LAN (WOL) including remote WOL 
- Scan of custom IP ranges 
- Possibility to set custom device name
- Filtering and search in the discovered device list

Network connections (availabe on Android 9 and below only):
- Similar to unix netstat tool - see network connections made by other apps
- Local & remote address and port number, state of the connection
- Remote hostname
- Name of the app which made the connection
- TCP, UDP, IPv4 and IPv6

Routing table:
- Destination & gateway, interface used, flags
- Both IPv4 and IPv6

Ping & traceroute:
- Round trip delay including IP address and hostname for every network node 
- Geolocation data including latitude, longitude, country, city, and time zone 
- AS number and network name information 
- Complete trace route visualization on the map 
- Graphical ping statistics updated in real time
- Both IPv4 and IPv6 - selectable

Port scanner:
- Fast, adaptive algorithm for scanning the most common ports or user specified port ranges 
- Detection of closed, firewalled, and open ports 
- Description of the known open port services
- Scan of complete port range or user-editable common ports
- Both IPv4 and IPv6 - selectable

Whois: 
- Whois of domains, IP addresses and AS numbers 

DNS lookup:
- Functionality similar to nslookup or dig 
- Support for A, AAAA, SOA, PTR, MX, CNAME, NS, TXT, SPF, SRV records 

Internet speed: 
- Test of both download and upload speeds
- Graphical speed test view
- Speedtest history 

Network information:
- Default gateway, external IP (v4 and v6), DNS server, HTTP proxy
- Wifi network information such as SSID, BSSID, IP address, subnet mask , signal strength, etc.
- Cell (3G, LTE) network information such as IP address, signal strength, network provider, MCC, MNC, etc.

Local service discovery:
- Bonjour service browser
- UPNP/DLNA service and device browser

More:
- Full IPv6 support everywhere
