If the network consistently takes longer than five seconds

to connect, you may need to adjust the settings:

• Set the connect time window to a longer value (use the

Connect Time tool to help determine this value) or,

• Change a connection component like channel AutoFind

or DHCP.

Note:

Extending the connect time may decrease bat-

tery life. The battery meter may need to be

reconfigured (contact Vaisala Technical Sup-

port).

Verify that the network exists.

Verify signal strength. Use the built-in signal strength

meter. Determine if adequate signal strength exists at

that location.

Verify your network settings.

Make sure the router or Access Point accepts connections

of 1 Mbps. Some access points may be set up to exclude

certain WLAN data rates. You may have to change the

WLAN data rate setting in the HMT140.

If the HMT140 was previously connected at one location,

but will not connect at the new location, temporarily

move it to the previous location and verify operation. It is

also possible that a setting on the network has changed.

Verify that you are connected to the right network.

Use the Ping from Sensor function in the HMT140

Utility to ping an address that should be available from

the network (verify that the address is ping-able).

Use the Ping from PC function in the HMT140 Utility

to see if your PC can ping an address on that network

(your PC must be connected to that network).

Use the Ping from PC function in the HMT140 Utility

(if this PC is connected) and see if you can ping the

HMT140 when it is in Config mode. Go to the Status tab

to determine the IP address.
