RV180W with 1.0.2.6 Firmware - Static DHCP problem

Question

Today I installed the 1.0.2.6 Firmware on a RV180W. I only have now two problems regarding the Static DHCP support in the GUI.
1. Via the Networking > LAN (Local Network) > Static DHCP I have no buttons to Add a new static Lease.
2. Via the Networking > LAN (Local Network) > DHCP Lease Clients I can thick a Lease and click on Make Static IP. The result is an error: Operation failed.
Is this a bug or am I doing something wrong?

Answer 1

RV180 f/w 1.0.4.14
Static DHCP page – missing buttons Add, Edit, Delete since some f/w update.
Apparently Cisco has changed syntax since some f/w version I don't remember.
Fix:
1. Backup unit's settings. Use some editor to check that the syntax for the section DhcpfixedIpAddress is correct in the configuration file. The main clue is a new variable "Name". An example bellow displays 2 lines in Static DHCP page. If necessary make changes most likely including upper/lower case conversion for MacAddr and the lines order.
2. Change checksum to 0.
systemConfig[1]["checksum"]="0"
3. Restore unit's settings from the edited configuration file. I have got missing buttons back only after the above procedure. Any other suggested solutions didn't work for me.
Correct syntax for newer firmware:
ifStatic[4]["SecondaryDns"] = ""
DhcpfixedIpAddress = {}
DhcpfixedIpAddress[1] = {}
DhcpfixedIpAddress[1]["MacAddr"] = "bc:ee:7b:e3:3b:0a"
DhcpfixedIpAddress[1]["Name"] = "Computer01"
DhcpfixedIpAddress[1]["IpAddr"] = "192.168.1.100"
DhcpfixedIpAddress[1]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[1]["_ROWID_"] = "1"
DhcpfixedIpAddress[2] = {}
DhcpfixedIpAddress[2]["MacAddr"] = "00:15:e9:6a:0f:15"
DhcpfixedIpAddress[2]["Name"] = "Unknown"
DhcpfixedIpAddress[2]["IpAddr"] = "192.168.1.101"
DhcpfixedIpAddress[2]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[2]["_ROWID_"] = "2"
DhcpLdapServerInfo = {}
Old syntax incompatible with newer firmware:
ifStatic[4]["SecondaryDns"] = ""
DhcpfixedIpAddress = {}
DhcpfixedIpAddress[1] = {}
DhcpfixedIpAddress[1]["IpAddr"] = "192.168.1.100"
DhcpfixedIpAddress[1]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[1]["_ROWID_"] = "1"
DhcpfixedIpAddress[1]["MacAddr"] = "BC:EE:7B:E3:3B:0A"
DhcpfixedIpAddress[2] = {}
DhcpfixedIpAddress[2]["IpAddr"] = "192.168.1.101"
DhcpfixedIpAddress[2]["LogicalIfName"] = "LAN"
DhcpfixedIpAddress[2]["_ROWID_"] = "2"
DhcpfixedIpAddress[2]["MacAddr"] = "00:15:E9:6A:0F:15"
DhcpLdapServerInfo = {}
