        AKB4000005: Care and feeding of a wireless router

        By @CanadianTech

        Published 5 Feb 2017 rev 1.0

        Assuming the modem your Internet Service Provider supplied you has a built in wireless router, try it and see how well it  works for you.  The key questions are, how good is the wireless signal strength and whether it drops signals.  Go to http://www.speedtest.net to see how it does in different parts of the house.  If that is satisfactory, stick with it.  The actual supplied speed is best tested on the same site with a computer connected by Ethernet cable.

        Keep in mind that a wired connection using an Ethernet cable to the router will always deliver superior speed.  For example, many printers have Ethernet connections and can operate as a network printer by plugging them into your router (or the supplied modem with router).

        It has been my experience that the wireless facilities in provider-supplied modems do not do a good job of wireless.  If that is the case, you will need to get your own wireless router and get your Internet Service Provider to shut down the wireless facility in their modem.  In my neighbourhood, the Hitron CGN3 is offered.  It is the only ISP provided modem/wireless router that I have found that delivers good wireless.

        You should not have more than one wireless router in a network or even try to connect one to another.  In some wireless routers there is the capability of shutting down the router function and having them operate as wireless access points which acts like a signal repeater.  In that case the wireless access point wirelessly connects to the main wireless router and has the network key (password) to it.

        Check list & Tips

        1. Microwave ovens
        2. 2.4Ghz cordless phones
        3. Large metal objects like refrigerator, freezer, cabinets, laundry
        4. Metal in walls, floors or ceiling — some apartment or condo buildings are built of Concrete with reinforcing steel rods in it.
        5. Near large steel beams either in floor, ceiling or walls
        6. Your computer itself
        7. Other electronic devices such as a TV
        8. Sometimes other nearby neighbours can cause this through use of over-powered wireless systems
        9. If you are located near an airport or other place where radio signals are used extensively    Most (not all) routers have an ip address of 192.168.0.1.  Entering that in the Internet Explorer address bar should bring up a window for entering user id  and password (not necessarily the same as the wireless key).  You must have this.   Once past that point, you can do all kinds of manual setup.  For example the wireless encryption key (other names too). You can reset your router back to factory defaults by using a straightened paper clip.  Press it into the tiny hole in the back that says reset while the router is powered up.  Hold that pin there for at least 15 seconds.
        10. Many routers then have a user id of admin and no password.
        11. Do not get carried away with WiFi security.  It can not be accessed from any point much further than about 50 feet.  Write the key you create on a sticker and put it on the router or modem.
        12. There is a type of technology that few will tell you about that can make a huge difference for this type of problem.  It amazes me that more people, even technical people, are not aware of it.  It is actually in some routers and notebook PC radios and the sellers don’t even know it.  It is called MIMO, which stands for Multiple In Multiple Out.  It is supported by n radios, and will be used provided both the sending and receiving devices are capable.  It works by transmitting on 2 or more closely adjacent band widths simultaneously.  If a packet of information is lost or garbled, MIMO attempts to find a better copy of the packet from the adjacent stream, and is usually successful.  Obviously 3×3 MIMO systems are better than 2×2.
        13. If you buy a new router, you should insist it has MIMO and you may have to do a lot of research to find which ones have it.  More than you might think, but their sellers don’t know about it.
        14. Wireless n devices (both router and the radio in your computer) are much better capable of handling this interference.  Check to see if your router supports n and that it is set up to run on n if your devices talk to it on n.  You will need help from your ISP (Internet Service Provider for this).
        15. You should not have more than one wireless router in a network or even try to connect one to another.  In some wireless routers there is the capability of shutting down the router function and having them operate as wireless access points which acts like a signal repeater.  In that case the wireless access point wirelessly connects to the main wireless router and has the network key (password) to it
        16. Placement of the wireless router can be very much the cause.  It should ideally be near the centre of a building.  It should be high in a room not down low to the floor where it can pick up more interference.  Not near a wall or other electronic device.  Sometimes just moving a router a foot or two can make a huge difference.  Likewise the way antennas are pointed, assuming your router has one or more externally

        To prevent your home router from being hacked, change the default router password(usually is just “admin”) by navigating to http://192.168.1.1 or .0.1 on yr browser;
        disable WPS or WDS;
        disable Remote Access Control or Remote Assistance;
        set WPA2-Personal/TK/AES encryption(n not WEP) n a strong password for the Wifi.

        The WPS/WDS feature allows a friendly probing device, eg a visiting friend’s smartphone, to be automatically connected to the Wifi by pressing a small button at the back of the router(= no need to enter the Wifi password). This can be a vulnerability. Nearby hackers or neighbors may use Wifi scanning software to hack yr Wifi password.
        Remote Assistance can be re-enabled for a short while when requested by the ISP for trouble-shooting the Internet connection. Eg rogue ISP employees may use the Remote Assistance feature to “borrow” yr Internet connection = you will experience abnormally slow browsing.

        It seems a few brands of modem/router now use 192.168.20.1+ as their default range, which can prove difficult to alter when replacing an existing modem/router using 192.168.1.1+
