Hi Graham
=A0
Are you sure the problem is the router?
=A0
136, 500, 160 and to=A0some extent 80m here are kill the ADSL. Even at ver=
y low powers. If your ADSL is cut during your transmissions only and resum=
es at the original speed directly afterwards it may well be the router bei=
ng temporarily being knocked out. If however you line stays down for a per=
iod of time say several hours then it is not the router. What you are doin=
g 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 wi=
thout technical intervention by BT Open Reach. If it goes down to about 30=
0/500kb/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 perio=
d 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=A0it is al=
l provided by BT they own the final mile and the exchange ...... legal nic=
eties to one side it is a fact.
If=A0you get a good Broad=A0Band data rate of say 4/8mb/s your transmissio=
ns on=A0LF/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 wip=
e out your ADSL for a week or more. So=A0without a lot of letter=A0writing=
 to BT and angry phone calls your ASDL will not return to original speed..
=A0
To maintain a usable data rate on Broad Band here I can not use 136 or 500=
kc/s above a few Milli Watts at TX output about 1=A0Watt on 160m 80 about=
 50Watts and on 60m and above=A0100Watts (possibly more but not tested yet=
). Also the longer you stay on the worst the speed degrades.My guess is wi=
th ADSL2 having a much wider bandwidth the problem for Amateurs will exten=
d further up the spectrum than shown above.
=A0
Hope you are not in my situation....... Oh and don't believe all this Fibr=
e stuff.=A0Open 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=A0BT is Wedded to=
 copper wire. So we locally have Internet breakdowns owing to Junkies and=
 the like ripping the Copper=A0cables out of=A0BT ducting to pay for drugs=
... Bedfordshire has had Internet disconnections for days owing to this ph=
enomenon. So along with cable theft and the lack of trained staff a=A0prop=
er interference free Broad Band coverage using fibre=A0in this country is=
 looking particularly bleak.
=A0
Good luck!
