Problem
▪
Slow Web Interface
▪ Unable to logon to the Web Interface
Solution
▪
Check the Ethernet duplex settings of the PC or switch connected to it. Set the PC or switch to auto-
negotiate, or half duplex if auto-negotiate is not available. The NMS ports on the radio are auto-sensing for
speed and duplex.
▪ Check that the IP address of the PC is in the same subnet as the locally connected radio, that is, 10.0.0.0.
▪ Check the CAT5 cable by using an Ethernet cable tester or using the same cable with another known good
device.
