Since this thread started, Sky have 'capped' me (at my request) down to circa 10mb downstream.

My line has not disconnected since this was done, but I do have fingers crossed as I have experienced this before - no disconnects for several hours (I think 95 was the record) followed by several within just a few.

Sky today advised me to "reset the router at frequent intervals to refresh it"... hmmm.

Anyway, current router stats are :

Upstream Speed: 574 kbps
Downstream Speed: 9984 kbps

Prior to that, and from memory, I had circa 14mb down, 676kbps up.

Incidentally, I apologise for turning an AAISP forum into a Sky one! Certainly not intended as my initial question was primarily aimed at migration concerns, my issue with Sky being a background as to why I was contemplating the move.

One thing you can do and AA may be able to help with this, is a bin plot to see if the interference if that is what is, is at a specific range of frequencies.

Things like a flourescent lamp can cause RF noise, and appear to function perfectly correctly, finding these sorts of noise sources is complex and expensive, and as the line seems to be running at over 8Meg I doubt BT will entertain much in the way of fault resolution.

The stats are useful as they sometimes indicate the type of line problem or likely cause - and the line is the same regardless of whether you are using Sky, AAISP, or any other (ADSL based) ISP.

In this case the stats don't help (at least they don't help me).

Your current router stats, which IMHO unfortunately had to be drawn out of you like a decayed tooth and you provided in dribs and drabs, would indicate that your line is healthy.

You have plenty of downstream noise margin at your current sync speed of 10 Meg.

Reducing your noise margin to a target 6 dB might gain you about 3 Meg, probably in line with what you were getting before you were 'capped', but we will never know the stats at that time.

We have no fluorescent lights in the house, and the router and where it connects to the master socket are 'isolated' in a storage cupboard away from any noticeable forms of interference. This cupboard is on an outside wall so not adjacent to any neighbouring interference by some 30' or more.

The power to the router is via a UPS which is via a surge protector.

Hi,

This may help although it is rather random. The bell wire in house telephone wiring is these days generally redundant. However, it is susceptible to picking up interference from various sources, such as those previously mentioned. In my case I am a radio ham and when I transmit on certain frequencies I manage to kill the router, which only resets when I stop transmitting.

Your fault is typical of a random event such as this. Maybe there is a radio ham near you or a cb'er.(look for aerials in the garden). If there is ask him to transmit and see if your router crashes.

It may be useful to see if it happens at certain times of the day i.e after 6pm or during the normal working day. This could indicate a business nearby causing the problem, such as arc welding.

Have a look on the web for extension wiring and this way you can identify the "bell wire". This can be disconnected providing you don't have a really old style telephone. Having said this, you say the problem occurs when the router is connected to the BT master socket. I presume this means with the front plate removed. The BT master socket has an external socket which is connected to the house extn wiring. If you remove this, you disconnect the internal house wiring. Once the front plate is removed you will see another socket, this is directly connected to the BT incoming line. This is where you need to test. (Sorry if that's teaching you to suck eggs)

Best of luck

Paul

A UPS contains electronics (rectifier, inverter) that are likely sources of RF interference. Try it without that.

You don't put the ADSL through the surge protector do you ?

This is a discussion forum, where different contributors will have different slants on the subject matter and may chuck in their pennyworth. You cannot channel or prescribe the replies. Problems are better solved by many varied minds attacking it.

I was chucking in my pennyworth on topic to question your assertion that "it is clearly a fault with the line".

Previously you demanded that we assume that you were unable to obtain the router stats when clearly you were.

Less technically minded "consumers" than you have been able to get and post their router stats here in order to help others help them.
