For improved performance, you must therefore periodically review and adjust the settings. Initially, modify the wireless configuration via the Linksys re6300 setup page by using the advanced settings options. Adjust the settings to your preference or what is appropriate. Additionally, move the extender to the WiFi dead zone to eliminate them permanently. For a dependable signal transfer, the simple recommendation here is to use wired connections rather than wireless ones.
