U30 WiFi Trouble shooting helper.
The
following is a guide for trouble shooting WiFi connectivity issues a customer
may be having. Also, the guide assumes that you know a bit about the U30
WiFi and/or networking in general.

First
things first: You must know all Wifi configuration will be different, with the
exception of a completely open network. (No encryption what so ever) If
the network has no encryption, most likely we will not get a call. (If
only everyone was honest; but then we wouldn’t have a job so…….)
Verify
the customer has run the Hobo Net Setup utility. In Net Setup, under
option 4, the customer will enter all of the pertinent network
information.
Verify
the logger battery is in good condition and fully charged. If you have
had many failed connection attempts, a AC charger maybe necessary
Notes:
1)
The battery level is a 20 minute rolling average, with
one sample taken every minute. That average has to be at or below 3.9V before
we stop communicating. The graphed data is the PIC measurement of battery voltage,
the calling is controlled by the ARM processors view of battery voltage. It is
possible for there to be a slight offset between the two.
2)
The averaging is
used for the alarm as well. It is possible that the average hasn’t dropped
below 4.5V yet. Scott is going to do some experimentation to make sure that the
alarm functions as designed.
TechNote onset® Recovering HOBO® U30-WIF from
‘Factory Defaults’ Before beginning, please have a printed copy of this
document on‐hand if possible.
Applies to: U30‐WIF
Problem: The
U30‐WIF (Wi‐Fi version) has accidentally been restored to ‘Factory Defaults,’
which are not the Onset factory defaults. Instead, this causes the
Lantronix Wi‐Fi module contained in the U30 to be restored to its factory
defaults, which are not compatible with the U30.
Background information: The main issue is the Lantronix module’s factory default serial
protocol is 9600 baud with no flow control as compared to 115200 baud with
hardware flow control.
Solution: Use
the HOBO NetSetup utility to reconfigure the U30 as instructed below.
Materials needed: PC, Type A to mini‐B USB cable, ‘HOBO NetSetup’ utility
(downloaded from Onset web site to PC)
If you make a mistake in entering any of the information, simply
repeat that step when presented with the main menu again. There should be no
need to power down the device or terminate the program prematurely.
Procedure:
1. Power down the U30. Important: Unplug any solar panel or
AC adapter before unplugging the battery, to prevent possible damage to
the U30.
2. Connect the U30 to PC via USB cable (type A to mini‐B).
3. Run the ‘HOBO NetSetup’ utility (do not click ‘Begin’ on
startup window until step 5).
4. Power up the U30 and wait for PC to detect device. You will
hear this sound once detected (click this icon ).
5. Now click ‘Begin’ on the ‘HOBO NetSetup’ utility
startup window. Wait for the text to stop scrolling and the ‘Change Setup’
menu to appear (see figure 1).
6. Type ‘1’ and press ‘Enter’ to bring up the
Channel 1 settings screen (see figure 2).
7. Starting with ‘Baudrate’, key in and press ‘Enter’
for each value shown in parentheses in figure 2. NOTE: For all screens
in this procedure, any value shown in boldface is particularly critical.
After the last value has been entered, the ‘Change Setup’ menu will
reappear.
8. Type ‘2’ and press ‘Enter’ to bring up the
Channel 2 settings screen (see figure 3).
9. Key in and press ‘Enter’ for the one value shown in
figure 3. Again, you will be returned to the ‘Change Setup’ menu.
10. Type ‘5’ and press ‘Enter’ to bring up the
Expert settings screen (see figure 4).
11. Again key in and press ‘Enter’ for each value shown in
parentheses.
12. At this point, the device has been reconfigured to an
operational state. To save the changes in the device, enter ‘9’ at the ‘Change
Setup’ menu to ‘Save and exit.’ The ‘HOBO NetSetup’ utility will
automatically terminate.
13. From here, the device still needs to be configured to be able
to attach to your network. Again run the ‘HOBO NetSetup’ utility and
navigate through options ‘0’ and ‘4’ to configure your server and
WLAN as necessary. The options can be seen in figures 5 and 6; although your
resulting configuration may differ depending on DHCP settings and network
parameters.

Info entry, 10/1/09 :
Remove or adjust all IPS ( also known as IDS ) systems on WIFI
network. These intrusion defense type system can cause devices like
the U30 Wifi to not connect.
“An Intrusion prevention system (IPS) is a network
security device that monitors network and/or system activities for
malicious or unwanted behavior and can react, in real-time, to block or prevent
those activities. Network-based IPS, for example, will operate in-line to
monitor all network traffic for malicious code or attacks . When an attack is
detected, it can drop the offending packets while still allowing all other
traffic to pass. Intrusion prevention technology is considered by some
to be an extension of intrusion detection (IDS)
technology.”

When
all else fails with the net set up, think of this: (This may be very
rare)
Situation:
All
the net set up information is entered correctly but the unit will not connect.
You can see the unit's Mac address on the networks firewall but it never
fully connects and never contacts hobolink. You may have even tried
pinging hobolink.com and it works. You have tried everything, like a million
times.
Possible
solution:
Although
you want to use a passphrase (12345) because everything else on the networks
seems to work like that ,try the following steps instead:
Enter
the WEP or WPA key as a hex string (key type = 0)(0102030405), it may be
necessary to convert this passkey to the ascii value (3132333435) depending on
the network. Follow this link for a ascii look up table.
"If
this fails, hang your head in shame and create an RMA for credit. Or you
can send Mike and Scott out on a field trip. Good Times!"
