1INTRODUCTION
1.1 Outline
Should it happen that the boot loader becomes corrupted on a WR11 product, it is possible for an end
user to re-load the boot loader by following this guide.
The symptoms of a corrupted boot loader are usually as follows. When applying the power, the only
LED to illuminates is the power LED. It is also possible that other “unusual” LED patterns may occur
depending upon how “damaged”the boot loader is.

3.5 Reviewing Flashwriter error messages
If during the previous session an error occurred, please check the table below for the recommended
course of action:
Error Message
Recommendation
sbios upload not confirmed by unit.
Check that this repeatedly fails and that you can carry out the procedure
correctly on a known working router. If so then please create an RMA with
reason Flashwriter sbios upload not confirmed by unit.
Scan failed DO NOT remove power from unit.
Ignore the message, remove the power try again. Check that this repeatedly
fails and that you can carry out the procedure correctly on a known working
router. If so then please create an RMA with reason Flashwriter scan failed.
Error re-accessing bootloader, >> prompt not
received after sending password.
Check that this repeatedly fails and that you can carry out the procedure
correctly on a known working router. If so then please create an RMA with
reason Error re-accessing bootloader, >> prompt not received after sending
password.
Unit did not reboot successfully after loading
bootloader.
Check that this repeatedly fails and that you can carry out the procedure
correctly on a known working router. If so then please create an RMA with
reason Flashwriter: Unit did not reboot successfully after loading
bootloader.
Unable to start TFTP
Check that the Ethernet cable is connected correctly and the LAN LED is on.
This error can often be “user error” or “network issues”. However if this error
is repeatable on the suspected bad router but does not occur on a known
good router then request an RMA with reason. “Flashwriter TFTP failed to
start”
Blue progress bar moves, but slowly and with
lots of re-tries and eventually fails.
This suggests a hardware problem or a network issue on your LAN. Check
again that this works on a known good router, if it does and it still fails with
this error on the suspected bad router then request an RMA with reason.
“Flashwriter TFTP failed to complete”
Unable to communicate with device after
reboot
Check to see if the router is continuously rebooting. Please contact Digi
technical support for help.
W-WAN module failed check - please check
you selected the correct module!
Be very careful to check that you are selecting the correct radio module
when you launch FlashWriter. This is the number one cause of this error! If
you are unsure of the type of radio module fitted open the case.
If you are sure you are selecting the correct radio module and if this error is
repeatable on the suspected bad router yet works fine on a known good
router, please request an RMA with reason: “Flashwriter radio check failed.”

4CHECK LEDS
The POWER LED should be illuminated when the device is turned on. If there is an LED fault with,
please request an RMA with code:
“POWER LED failure”
The SIGNAL LED will be illuminated after 1-2 minutes from boot if the cellular module is working and
configured properly. If the device obtains an IP address but the LED is faulty, please request an RMA
with code:
“SIGNAL LED failure”
4.1 Check Service LED
Connect the Ethernet port to a switch.
Access the CLI (Command Line Interface) –this can be achieved:
Via a telnet or SSH connection
Via the “execute a command” page of the web user interface.
Issue the “flashleds” command and check that the SERVICE LED is illuminated/blinking. If there is an
LED fault please request an RMA with code:
“SERVICE LED failure”

5CHECK USB BUS
Check that the W-WAN module is shown on the USB BUS of the unit
Access to the CLI (Command Line Interface) –this can be achieved:
Via a telnet or SSH connection
Via the “execute a command” page of the web user interface.
And issue the following command:
busb show
2 devices should normally be present:
Device in “BUS 1, dev1, depth 0”
Device in “BUS 2, dev1, depth 1” (This is the radio module, if it is missing, the module may be
mid power cycle, wait a few seconds and issue that command again. The text of this will vary
based upon the type of module fitted. )
If the device in BUS 2, dev1, depth 0 is not present, please request an RMA with code: “Cellular module
not shown on USB BUS”

6CHECK W-WAN CONNECTIVITY
6.1 Test SIM detection switch
With the router powered off, insert a SIM card into BOTH SIM slots of the WR44V2 and open the CLI
interface.
Access to the CLI (Command Line Interface) –this can be achieved:
Via a telnet or SSH connection
Via the “execute a command” page of the web user interface.
Issue the following command:
simconn ?
This command tells you which SIM slots are populated and also the SIM that is currently in use. The
value before the comma is SIM 1 and the value after the comma is SIM 2. 1000 means that the SIM is
present. 1001 means that the SIM is present and the active SIM. Here is a summary:
1 = SIM not present
1000 = SIM present
1001 = SIM present and connected
The output should be as follows:
simconn ?
simconn: 1001,1000
OK
Showing that SIM 1 is present and active and SIM 2 is present.
If the SIM cards are physically inserted but do not show as present please request an RMA with reason
“SIM DETECTION FAIL”

7CHECK W-WAN SIGNAL STRENGTH
Whilst the internet link is still connected from step 5, access the CLI (Command Line Interface)
Access to the CLI (Command Line Interface) –this can be achieved:
Via a telnet or SSH connection
Via the “execute a command” page of the web user interface.
And issue the following command:
modemstat ?
Check that the signal strength is roughly what you normally get (+/- 10dB) with the same antenna in
the test location.
If the signal strength is much worse than normal, make a note of the cell ID (lac:00DF ci:01B0BD51 in
above example) and repeat the test on a known working WR11 that contains the same type of radio
module in the same location. Ensure the known working WR11 is connected using the same antenna
and connects to the same cell ID (lac:00DF ci:01B0BD51 in above example). If it does and the signal
strength is much better (+ 10dB) than the suspected bad router, request an RMA from Digi technical
support with code: “Cellular signal strength low”

8CHECK ETH PORT
Note that it is not necessary to test Eth port 0. This was testing during the flashing process. However if
you observe intermittent issues, it might be necessary to run several tests.
Configure eth port 0 with a valid and free IP address on the same subnet as your test PC, e.g.
eth 0 ipaddr 10.1.208.11
From your PC, first clear the ARP table, from the windows command prompt and issue this command:
arp –d *
Then check that you can ping this IP address. If an intermittent issue is observed, let the ping run for a
longer period (-t option)
If it is not possible to ping this addresses and if you repeat this test on a known good WR11 and it
works fine, please request an RMA with code “ETH 0 test failed”.
