If you go with a
router that has a WAN port like the ones I suggested it will work with every ISP on the planet.....
I dont mean that cheap, earlier i finalized 56U but examining the hassle & beams performance, i now finally go for 13U.
I dont want to put 2 device to for the same purpose and i know tech will change radically in next year, making everything which is today's "beast" looks like crap.
I remember when i bought this
Linksys, it was against-order back in year 2007 costing Rs.6000+ was top in evety review that time for home gateway. now it doesn't even worth 500/-
e.g, if i switched to Airtel, i already have Linksys Gateway so 1 device & work done.
and if Hayai, MG said somewhere he will provide CPE with wi-fi Again 1 device work done.
and if required will use N13u as an repeater if required.
