I suggest routers with Repeater mode built-in on stock like Asus they have a Universal Repeater mode.
Another way is using WDS since you're buying new routers anyway might as well get identical models with high gain antennas.
Currently testing an Asus RT N12 HP @200mw tx power + 9dbi antenna kaso sobrang mahal 3k.
Step by step... depends sa model so refer na lang sa manual, foolproof naman mga manual ngayon sir.
I'd say just avoid the linksys, mahal ang high end nila and their low end has poor signal, well justified because walang external antenna cost savings siguro nila.
3. Pag po ba naka Dual WAN nagpasasama nya ung speed ng dalawang ISP. May iba kasi na nagsasabi na magksama daw, ung iba naman sabi once na down ung isang ISP automatic up ung isang ISP?
4. Okay lang po ba na isang router lang sa 50 clients user?
5. Baka po may suggestions kayo na network setup para po pag nagdagdag pa ng client. Mga 70 estimated number of users in the future.
3. yes and no - load balancing, hindi niya pagsasamahin yung speed pero i-distribute niya yung usage sa dalawang internet mo.
Hindi siya 1+1 = 2 bale 1+1 = 1+1 pa rin. if you have two youtube sessions 1 will go to WAN 1 and the other will go to WAN 2.
Torrent can utilize both well because by design.
4 I suggest replace the router with something more powerful, the Linksys E1200 uses a weak CPU; something along the lines of a WDR 3600/E2500 onwards/RT-N16u onwards or maybe a pfsense server will serve better. wala ako alam sa PFsense pero may pfsense thread naman tayo,
5 Dagdag ka na lang ng Switches going to main router okay naman yung topology mo.
