ModemDoctor for WindowsYour source for reviews, information and software for communication devices ModemDoctor NewsGoodbye Binary?Other communication forms like HDTV over-the-air ATSC use multiple levels to encode information instead of just binary 1s and 0s. Now someone is thinking seriously about doing this for fiber transmissions to increase througput.

The principle is sound enough...just curious about the SWR (old radio term).Apple Discontinues Airport WirelessThese devices have not been cost-competitive for years and lack features that most "appliance-type" wifi routers currently offer to users. Apple will continue to support these and may in the future offer a new product.

There is more in this Networkworld article, , but the quickest fix you can do today is use a 5ghz channel in your home.Three Simple things you can do to increase WiFi speedsFirst, use the 5ghz band and 80211ac - Its very fast (assuming your computer has a wireless adapter that is compatible), but even an 802.11N will see better speed.Second, check your router security settings. Make sure you are using WPA2/AES instead of WEP. WEP is a security issue and also a slower protocol.Third, If you must maintain older standards, put those on the 2.4ghz band. Reserve that for 802.11b/g connectivity. All these channels are heavily congested so either use the auto select feature in your router to find a channel, or use a wifi analyser. You can find several on the Microsoft Store that are free to use.5G Technology is coming....soon5G wireless is going to change how we manage our homes. All of the smart and connected devices of the IoT will be easier to implement and connect promising multigig downloading speeds.

Newer devices can connected wireless at speeds close to 1gigabit per second. In my home, I top out at 889mb/sec...pretty fast.
