Extending your WiFi Coverage.

Extending your WiFi Coverage is not as simple as it is.... but it's quite effective.

Here are some tips:

NEVER USE A POWER LINE ADAPTER... PLCs are so susceptible to disruptions and also waste your money. They are limited to the old slower technologies. If you die-die need to use one.. then use it for your LAN Connection. Remember Singtel's mIOTV issues?? All caused by so much disruption etc as the customers do not want to have wiring or drilling. They opted for the ComTrend CHC and from my experience and toying about...they only go as fast as 70mbps... as 200mbps is ONE WAY or Half-Duplex. Full Duplex is 35% of their Promised Speed.

DO NOT USE WIRELESS-WIRELESS Extenders... or using WDS mode. They just amplify your poor signals and cause more harm to your expensive router.  It's just like a relay game.. using one channel.. every time there is a relay..someone will take 10-15% commission or cut from the bandwidth available. Eventually, you are better off using a hybrid mix.

DO NOT USE ROUTING MODE. Do you see the connection behind the router saying Broadband and then other 4 ports for LAN? If you need to do a chain relay.. don't plug into the Broadband port as it will firewall your connections and cause more harm.

Technically.. this is how you do it:
From your ONT (Modem) to the Router(A)... you set is as DHCP without using IP Addresses to (255 is broadcast).. or if you prefer 10.0.0.x or 172.16.0.x
Why? Because we want to use those IP. If you let your router handle more than 32 clients in one go.. it will CRASH!!!

So we have 2 routers.. how to go about?
We all know the router (A) may be (Typical... Singtel's is 254 as 1 & 2 used by ONT) and so we Statically Assign the Router (B) as 253 (255-2-N where N is the number of extenders). We disable DHCP from Router B so users will get IP addresses from router (A). And we MUST NOT use the SAME AP-Name or SSID for Router A and will conflict. You can try... but you have to allocate different channels.

Then from Router (A) we connect the LAN port via RJ45 cable to the Router (B) on the RJ45 port (not labeled Broadband). Then we have a distributed AP Network. If for some silly reason you still don't want wiring.. you can use PLC Adapters (get 300mbps or more) to connect those 2.

Any router can be used..even the Singtel black 5012 or 5520.. those MioV white boxes need to be reconfigured manually by Tomato.

It is a pain in the backside....but for quality reasons...we have to do so..especially when U are a Gamer or subscribe to at least 150mbps or more. Same senarios apply for Singtel 300Mbps packages.

Don't get DLINK or TPLINK.. they are RUBBISH. Get Netgear, ASUS Dual Band , CISCO or alike. LinkSys is also OK.

Cost wise: Around $200 for the additional Router, and $8 for wiring (including the casing/trunking box), typical HDB Maisonette uses 30 Meters End-to-End....  and much more for Landed.
