Hi Graham
Are you sure the problem is the router?
136, 500, 160 and to some extent 80m here are kill the
ADSL. Even at very low powers. If your ADSL is cut
during your transmissions only and resumes at the original speed
directly afterwards it may well be the router being temporarily
being knocked out. If however you line stays down for a period of
time say several hours then it is not the router. What you are doing
is putting noise (owing to RF) onto your line which is being picked
up at the exchange DSLAM. The exchange equipment (DSLAM) serving
your line will reduce data speed to ensure that a connection of
sorts is maintained. This speed can go down to below 80kb/s from
which it will not recover without technical intervention by BT Open
Reach. If it goes down to about 300/500kb/s it may well recover it's
original speed over a period of time BT quote 72 hours yes 72 hours
(I think this time period is not a technical issue but one to stall
the punters off). On a good day the recovery period can be speeded
up by turning the router off and disconnecting every thing from the
line and waiting. This makes a quiet line for the automatic recovery
to work.... on a good day!!! If you don't have enough life left to
wait for BT to physically do some thing then the best thing is to
write to BT HQ in London to the their CEO (his name and location can
be found with a bit of research) and tell him what you think of his
outfit. I know from experience he does not like receiving this kind
of letter. You may have your ISP as Joe Blogs Internet Provider dot
Com but in reality it is all provided by BT they own the final
mile and the exchange ...... legal niceties to one side it is a
fact.
If you get a good Broad Band data rate of say 4/8mb/s
your transmissions on LF/MF will only slightly degrade your
ADSL but if like me on the end of 7.5km of copper its only 1/1.5mb/s
on a very good day, RF will wipe out your ADSL for a week or more.
So without a lot of letter writing to BT and angry phone
calls your ASDL will not return to original speed..
To maintain a usable data rate on Broad Band here I can not use
136 or 500kc/s above a few Milli Watts at TX output about
1 Watt on 160m 80 about 50Watts and on 60m and
above 100Watts (possibly more but not tested yet). Also the
longer you stay on the worst the speed degrades.My guess is with
ADSL2 having a much wider bandwidth the problem for Amateurs will
extend further up the spectrum than shown above.
Hope you are not in my situation....... Oh and don't believe
all this Fibre stuff. Open Reach have told me that one reason
why Fibre is not being rolled out like the Virgin setup is that
there are only a few BT people capable of working with Fibre. This
is the reason why BT is Wedded to copper wire. So we locally
have Internet breakdowns owing to Junkies and the like ripping the
Copper cables out of BT ducting to pay for drugs...
Bedfordshire has had Internet disconnections for days owing to this
phenomenon. So along with cable theft and the lack of trained staff
a proper interference free Broad Band coverage using
fibre in this country is looking particularly bleak.
Good luck! 73 es GL

Any ADSL2 BBand router /
RF proof ?
Just upgraded to ADSL2
with a orange net-gear router/wifi
router, now 15 watts on 160
kills the connection
router is in the same location
as the old edimax , which kept running
with 200 watts on 500 K and 400 on Hf
? any RF proof
ADSL2 on the market >
Tnx -
