especially if you can nail it down to times with your neighbours when their DSL goes slow.
This is the key.
If all your neighbours with broadband, experience the same problem at the same time each day, then that is strong evidence of a localised fault and it's the various ISPs responsibility to resolve it with BTO.
The pattern is very clear, it's happening every single day now between 10am and 10pm on the dot(look at first page), I have let them know this on the letter I have posted, and if their problems are occurring at the same time to at least make their ISP aware.
Not had a response from any other neighbours yet but a lot of them are using Virgin's cable service so won't be affected.
I am just trying to get an idea of what sort of building the interference could be coming from and what sort of device could be causing it:
First of all anything above 40% packet loss is when I get disconnected and the DSL switches off.
- I don't think it's a street light just because the larger areas of packet loss do not occur at the same time every day(i.e when the street light switches on at the same time every day.
- Looking at the packet loss it occurs from 10am-10pm most days.
- I don't think it's a household appliance like a monitor, Sky Box as I would expect for the interference to occur outside the hours 10am-10pm.
- Possibly could be someone's central heating, which is on a timer from 10am - 10pm, the peaks occurring when the central heating is turned up? There are no large peaks this weekend so it could be either a business(open Mon-Fri) or someone in a residential property who is away this weekend.
