Wireless N is relatively new and is still in drafting stage. No
guarantee if there will be major changes, just like how Bluray
changes (which by the way is so major that old Bluray products will
not be compatible with new Bluray products).
As for price difference, quite frankly, not all will agree with
it. Speed wise, it's a great improvement, but only if you are not
on the Internet. This means if you are sharing files within your
home network (say transferring files from your laptop to your PC),
the increase in speed will help. Internet bandwidth, on the hand is
determined by the ISP. Having such a great speed is thus
wasted.
Range wise, it has also been improved. Wireless signals will no
longer be as weak if you are too far from the router (but that
doesn't mean you can go too far away from the router). You no
longer need extra range booster to boost the range.
But as technology improves... it will seem like buying now is
not worth it... just like when wireless first came out... it was
darn expensive. Now? Not so.
Some will say these improvements will be worth the price, some
will say not...
I don't recommend Linksys at all, especially the Wireless G
routers. With each newer firmware upgrade, more and more problems
are introduced. I suggest you go for others.
By the way, need you to clarify something. Since you say you are
using cable modem, I assume that you are a Starhub user? If so,
yes, the product that you are looking at is compatible with Starhub
cable modems.
Yup, using a cable modem but from Pacific Internet. Started
with PI way before Starhub joined the market. Mine's 20 hours
free per month. But I am willing to switch
to Starhub even though with slightly lower bandwidth and
unlimited use. Too bad I'm still stuck with PI's contract.
