I'm trying to make an informed buying decision as we think about
upgrading the current Home Network; right now there is a Linksys 'G'
band router downstream from a DLS line .
(2 are hardwire 10/100bT & two others via 80211g wireless with an
additional single draftN unit in 'G' mode).

(Usually there are no more than three online at any given time.)

Right now I have the router locked to 'G'-only mode (no 'B' or mixed
mode), and any adapters bought in the future will likely be some sort
of draftN type, so what I'm wondering is:

- Are Simultaneous Dual Band routers able to avoid a bottleneck (if
there is really one after all) when used with both N and G clients and
hooked to a 1.5M DSL residential line? (Or, conversely, is it
marketing hype and/or overkill?)

- Has practical experience shown one brand/model to shine over the
others?

- Is there a great deal of performance plateaus between single radio,
Dual Band, and Simultaneous Dual Band routers?

Even with 'G'-based systems, with respect to using the internet connection,
*typically* the bottleneck is the internet connection, and not the wireless
speeds.

The wireless become the bottleneck when transferring data over the LAN,
between PCs.

as others will probably mention -
if the main or only traffic is to the DSL line
and the Internet.... vs any in-house data/streaming transfers -

Then a 1.5mbit DSL vs a 54mbit WiFi (G)
is hardly an issue :)
Heck - even a (B) at 11mbits is not an issue with a 1.5 DSL line

In fact - you might perform a speed test
and see your actual download speeds...

It might seem stupid and obvious but actually having it spelled out
like that does help.

I took a chance and ran it by the NG, Thx.

Something else that isn't obvious to most people is that Wifi speeds don't
represent an attainable throughput - IME being connected at 54Mbps equals a
throughput of about 22Mbps for example, with similar percentages at other
speeds. I haven't used N, but I've no reason to believe it'll be
substantially different.

It's a similar story with DSL too, with various overheads meaning that IP
throughput will be about 87% of your sync speed.
