interference between wireless network, cordless phones, etc

I've got a 802.11g wireless network in my home (Linksys equipment almost
entirely) and, while it works pretty well, the range isn't as good as
I'd like and it is subject to interference from my 2.4Gig cordless
phones, microwave oven and other "usual suspects". I've just read up on
the latest group of enhanced wireless routers that supposedly increase
range, increase throughput and reduce interference from other sources
(Linksys Wireless-G with SRX, D-Link SuperG with MIMO and something
coming out from Netgear). The reviews I've read say they work at least
reasonably well. OK. I've got two basic questions.

#1 -- How do they affect the OTHER DEVICES? Like my cordless phones?
Will these more powerful routers just drown out the signal to my
cordless phones so I can't use them properly? ALL of our phones are
cordless, and we use Vonage for our long distance, so increasing
interference on our cordless phones would be a disaster.

#2 -- Will we see a significant improvement with one of these new
routers even if we kept our existing 802.11g "cards" (some Linksys pc
cards), one Linksys PCI card, one Linksys USB adapter, one 3Com pc
card)? I'm less interested in improving throughput than I am
eliminating dead spots, improving signal strength and reducing
interference. Would I have to buy new adapters TOO to realize those
benefits?

Thanks for any information.

The questions would have a better chance of getting a good answer over
in But there doesn't seem to be any big jump
in power from these devices, they still have less power than most
booster or amplifier devices. The claimed range improvement seems to be
more from intelligent use of signal reflections rather than raw TX/RX
power. And if you're in an environment that doesn't have reflected
signals - guess what!

And just to mention one item, cordless telephone buyers have really been
led down the primrose path by marketers with that "see, this is higher
frequency so it's better" crap. A well-designed and built 900MHz phone
will have better range, better non-line-of-sight usability and won't
interfere with 2.4GHz networking equipment.

 

You could just replace your cordless phones.

I've got a VTech 2-line base phone and seven cordless handsets that work
great except for the interference issue. Not an expense I'm anxious to
junk.
