I have a CPE510 that is working fine with the following ip address:

 

Ip address: 192.168.88.24

Subnet: 255.255.255.0

Gateway: 192.168.88.1

 

Now i have made some upgrade to the router and made it a /21 subnet.

 

So i changed the cpe510 ip to the following details:

 

Ip address: 192.168.89.24

Subnet: 255.255.248.0

Gateway: 192.168.88.1

 

Now the problem is I cant accessnthe web management of the cpe, i have multiple cpe510 and they are all working fine with the new ip addresses, source and receiver CPEs are all working fine and getting internet/data like how they supposed to work but i just canr access the web management. I cant also ping the devices.

 

Solutions tried:

1. I tried to connect directly to the cpe and tried the following ip addresses in my laptop to try and connect

 

Ip address: 192.168.89.50

Subnet: 255.255.248.0

Gateway: 192.168.88.1, 192.168.89.24 and tried with no gateway too

 

Ip address: 192.168.88.50

Subnet: 255.255.255.0

Gateway: 192.168.88.1, 192.168.88.24, and tried with no gateway too

 

Did anyone experienced this? My head hurts just trying to fix this problem. Thank in advance guys
