Number of clients connected to wifi ap



  • I am trying to find the number of clients connected to my onion ap.

    According to openWrt this should be possible with iwinfo and iw.

    However I get the following:
    root@Omega-F142:~# iwinfo ra0 assoclist
    No information available

    root@Omega-F142:~# iw dev ra0 station dump
    nl80211 not found.

    I am using latest kernel release:
    *root@Omega-F142:~# oupgrade -v

    Device Firmware Version: 0.3.2 b232*

    It is a clean install, more system info below.

    Any suggestions?

    Regards
    Kim

  • The more area an access point covers the more variety there will be in the client connection qualities mytexasbenefits login



  • Most wireless access points and wireless routers can theoretically have 255 devices connected at a time!



  • @Welch-Jonas Probably you wanted to write 253 instead of 255.
    I think you are talking about IPV4 Class C Private networks eg. 192.168.0.x - 192.168.255.x (/24 or netmask 255.255.255.0).
    As you know the default IP address of Omega2 WiFi AP is 192.168.3.1, the Network address is 192.168.3.0 and the Broadcast address is 192.168.3.255 - so the usable client IP Range is 192.168.3.2 - 192.168.3.254 ie. 253 IP addresses.

    But
    uci show dhcp
    dhcp.wlan=dhcp
    dhcp.wlan.interface='wlan'
    dhcp.wlan.start='100'
    dhcp.wlan.limit='150'
    dhcp.wlan.leasetime='12h'

    So theoretically max 150 active and inactive (!!!) WiFi clients can connect to an Omega2's AP at a time and the default DHCP pool of is 192.168.3.100 - 192.168.3.249.

    BTW I'm afraid OP wants to know how many active clients connected are connecting to that AP "just know".



  • @Kim-Nyholm I think iw and iwinfo are not working as expected due to WARP CORE (the Onion Enhanced MT7688 WiFi Driver).

    Check the '/tmp/dhcp.leases' file that lists all the devices which connected to that AP so far (in the last 12 hours - it's the default lease time).
    If you want to know only the number of active clients then flush actualize the arp cache in some way.

    Do you want an example?
