Remember, there is no such thing as "harmful interference" in the ISM band.
Perhaps they're all on ch6 because they've "fixed" the unit to only run on ch6 because their spectrum looks like
crap, and its the only way they could get the device to pass FCC cert?
2Wire's FCC Grantee code is: <x-tad-smaller>PGR
PGRHPL000W
PGR2WHPLHW
PGR2W1000W
</x-tad-smaller>
and they have a new product, approved last month: <x-tad-smaller>PGR2WHPLHG. The block diagram says it uses an
RFMD 2163 PA, (http://www.rfmd.com/DataBooks/db97/2163.pdf) which is good for no more than 24dBm (250mW) even though the datasheet says it will do 25dBm (316mW).
This is the same PA used on the 200mW cards from Senao and Zcom. (There is a variant of the Zcom card
that is setup for 25dBm, but it pulls power back at the band edges.) Sure enough, if you read the test report,
they're generating 26dBm on ch1, ch6 and ch11.
Same as their other products, I think. Jim-bob sez, "Check it out yerself."

The trouble is that they drown out other potentially good signals. We've had
at least two installs that stopped working because a 2Wire signal appeared -
presumably after a neighbor ordered SBC DSL and received their combo DNS
modem, router and wireless AP box. Rumour has it that these are 300mW
devices.
And I concur with another poster - I'm sure many of the people with these
boxes don't even have wireless. Especially in our main neighborhood where
our signal is pretty ubiquitous. Many people find out about us just by
turning on their laptops..
I wish these boxes came with a little switch on the side "Wireless On/Off",
and shipped it off. Then people could easily turn it on if they need it.
Hmm, I wonder if there's any basis for an FCC complaint to the manufacturer
because they're causing so much needless interference? And, if we did make
a complaint, would it go anywhere?
