Intermittent connectivity may be caused by major problems with the Linksys ax1800 extender. An excessive distance between the extender and your current router could be the first major cause. After the Linksys ax1800 setup, you can move the extender, but it needs to be close enough to the current router. This implies that in order to receive rapid signal transmission, the extender needs to be inside the current router's range. If an ethernet cable is used to connect the two devices, make sure there are no signs of wear or tear on the cable. Additionally, confirm that your gadget is linked to the Linksys extender's official network. Other than that, make an effort to keep metallic objects and electrical appliances away from the extender. Which can create interruptions and barriers in the signal transmission process of the extender.
