Follow the instructions

Have you tried unplugging and plugging the power supply back in? If that doesn't help, try to check the manual for power issues:
Link DWL 2100AP user manual

To configure the modem properly, you should refer to the user manual. It has all the settings detailed as well as a troubleshooting list:

possibly cat5 cable problem or your DWL - 2100AP is only on wireless mode.

please check and put on mixed mode also.

yes you can do it put access point dricetly to the modem then you get it

I have had similar problems with DWL-2100 and (much less often) with DWL-3200. I have no solution, but a workaround: changing the authentication mode. For example, if the units are using WPA-Personal, I change it (on both) to WPA2-Personal or WPA-Auto-Personal. It doesn't seem to matter which mode is used, it's just the fact of changing it that helps (eventually). You may have to go through the process more than once. Also, realize that although the web interface comes up 30 seconds or so after a reboot, it may take another 30-60 seconds before a link is established, so don't give up too soon while trying these changes.

To use the DWL-2100AP as an access point (repeater), You have to set it up on the repeater mode and type in the MAC address of the router. The best way to do this is to run the AP manager from the cd.

If you can get into the built in webpage to upgrade firmware I would suggest upgrading it. Sounds to me like corrupted firmware. If you can I would return the device. I had a similar issue with a linksys AP and I found out that the Firmware was scrubbed. Had to send it back to the manufacture.

Try reseting the linksys! I am not super sure but I think that all of those devices are sucking the power out of the linksys. Again I am not 100% sure but try resetting!
