Low link quality or range can be caused by environmental interference, such as lead-based paint and concrete walls. Try to move the antenna of the Wireless MAXg Router or to reposition the wireless clients to improve the link quality. If possible, ensure that there are no obstructions between wireless clients and the Wireless MAXg Router.
Some electronic devices, such as 2.4Ghz phones and microwave ovens, may interfere with the wireless signal and affect your wireless range and link quality. Try creating a wireless connection on a different channel.
