Since WiFi is open to interference from baby monitors, cordless phones, microwave ovens and the neighbor's WiFi there is no reliable system available.
This is why you wire up what you want to be more reliable.
There are a few that haven't learned this but give them time.
Hello, Since Christmas I feel I now have pretty moderate wireless network bandwidth usage with 7 wireless devices connected. I also have 4 devices connected to Ethernet. I have an AT&T 2701HG-B Wireless Gateway/DSL router supplied by AT&T. The wireless network has started to become un-responsive since adding several additional wireless devices. I have read the Community Support posts and made the suggested changes to allow the 2701 to become more stable for now. I have heard to get the best performance from your wireless network when using several wireless devices it is better to have a separate DLS modem and connect it to a wireless/router. I would like to have any suggestions on a reliable DSL modem and wireless/router to purchase? Any advice would be appreciated. In the future I would also like to stream Netflix to my TV so even more demand will be placed on the wireless. GF
