Although the Linksys extender setup consists of easy-to-follow setup points you can accomplish them simply and with less effort. However, there might be a case when you get some setup difficulties during your Linksys re6400 setup. The worst case can be when you don’t know its troubleshooting tips or are unable to identify its source. But, here are the tips that will allow you to overcome those issues. First of all, check the extender’s placement and make sure it is located centrally in your place. Try to place it above the ground floor where there are no electrical appliances available. Then, check the connectivity between your extender, router, and networked device and ensure they all are attached strongly. Lastly, if your extender is not in its factory default state, then make it by resetting its settings.
