In both the web interface and the Tether app, the IP addresses for the connected clients is missing the final digit of the 4th segment in the sequence. For example, a client IP that should be "192.168.111.105" shows as "192.168.111.10", and a client IP that should be "192.168.111.104" also shows as "192.168.111.10". Now, as you can imagine, this can be quite confusing when viewing the list and seeing duplicate IP addresses, especially when they are outside the range configured in the DHCP settings in the router.
And, just to be clear, this is happening in both the web interface for the extender and the Tether app, so I'm guessing it's something that will need to be addressed in the firmware. Here's my DHCP settings on the router:
IP Address Pool: 192.168.111.100 - 192.168.111.249
Address Lease Time: 1440
Default Gateway: 192.168.111.1
Primary DNS: 220.127.116.11
Secondary DNS: 18.104.22.168
Please let me know if / when this will be addressed in a firmware update. Thanks!
