Question

So, the Router has the Ip Address 192.168.1.1. But, my Macbook then gets assigned (from DHCP) the 192.168.1.250 as the Router IP and thus I have no Internet Access. But, when I manually change the router IP address as 192.168.1.1 I have internet access.

So, why is the case that DHCP gives my Macbook the wrong Router IP adress: 192.168.1.250?

Answer 1

I see two possible explanations:

1. Misconfigured DHCP pool - assigning a gateway of 192.168.1.250

2. A second DHCP server on the network you are not aware of.

If you can pull a list of assigned DHCP leases from the router, you can probably determine if the Teltonika router is indeed responsible for assigning the IP address of your MacBook.
