8.3 Reset Button

The Reset button has two functions. If it is quickly depressed and released, the

modem will simply power cycle the internal hardware. If, however, the reset is

depressed and held for several seconds (count to 60 slowly and wait for all of

the lights to flash yellow continuously), the ALEOS® configuration settings

will return to the factory defaults.

9. Troubleshooting

Note that it can take several minutes (at least three) for the L300G to boot and

authenticate on the network. If you are not able to communicate after five

minutes, use the flowcharts below to troubleshoot the issue.
