For the best and easiest Linksys re7000 setup, a few things should be avoided the first time you try it. This will help you save time and effort due to a quick and easy setup. So, first is: do not place your extender too far from your router and as near as possible to nearby electrical appliances. Likewise, do not put your device at maximum distance away from the extender and router. Therefore, keep your device hardwired to the extender and do not use a wireless connection instead. Next, there must not be any spelling mistakes in the entered default web or IP address. Also, do not enter any wrong credentials while trying to log in to your extender. If you keep facing setup issues, it is better to seek help from a tech rather than trying to fix the issues by yourself.
