TROUBLESHOOTING

Make sure the gateway is using AES encryption or none at all.  If the Linksys WAG120N is using WEP or TKIP algorithms, the throughput between the gateway and the wireless device will be drastically reduced.

On the web-based set up page, go to Administration tab > Firmware Upgrade.  Select the file to upgrade by using the browse button and then click upgrade.  Do not reset or powercycle the unit while it is upgrading.

SPECIAL FEATURES

1. What DDNS providers does the Linksys WAG120N support?

DynDNS.org and TZO are the DDNS service providers supported.

2. What Internet browsers can the Linksys WAG120N be used with?

Microsoft Internet Explorer® 6.0 or higher, Firefox® 1.0 or higher, Google Chrome™, and Safari® web browsers can be used.
