You cannot access the router entered/used with your own IP address because in the IP address and the router address different subnets may exist as a result of their subnet mask.
The IP address and the router may only differ at the positions which are (binary) "0" in the subnet mask.
Example:
You entered the following:
Subnet mask 255.255.128.0 (= 1111 1111.1111 1111.1000 0000.0000 0000 B);
IP address 141.30.0.5 (= 1000 1101.0001 1110.0000 0000.0000 0101 B)
Router 141.30.128.1 (= 1000 1101.0001 1110.1000 0000.0000 0001 B)
In this example the IP address and the router have a different value at the highlighted position although there is a “
1" in the subnet mask at this position.
In the example you must change one of the following:
· Subnet mask to: 255.255.0.0 (= 1111 1111.1111 1111.0000 0000.0000 0000 B) or
· IP address to: 141.30.128.5 (= 1000 1101.0001 1110.1000 0000.0000 0101 B) or
· Router to: 141.30.0.1 (= 1000 1101.0001 1110.0000 0000.0000 0001 B)
