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.

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 - G..
