I've been with them on their "pro 16 Home" package for a month now and haven't received speeds of higher than 2Mb/s (actual dl speed fluctuates around 1.5Mb/s). This is fine obviously for email/basic web... but useless for video streaming. BBC iPlayer, Sky Player and YouTube are all un-usable.
I have tested at various times of the day, changed ADSL filters, tried 2 different routers etc. and still nothing. Living in London, approx 1 mile from Kentish Town Exchange (CLKEN) I had hoped/expected more.
So here is my problem. Xilo have escalated the issue with C&W who are adamant that I am syncing at 19Mb/s (my router currently shows 9470kbs) and "can see no fault". This brings us to the dreaded Engineer visit. I am only in this property for 1 more month and am loathed to spend any more money (I have already bought a new Billion 7800n Modem to try to solve the problem). I am even considering not paying my £17.99/month I am so unhappy with the service I am receiving.
The people before me in the flat had an "up to 8Mb/s" service with Orange and regularly achieved 5-6Mb/s dl. So I really doubt there is anything drastically wrong internally.
ADSL Link Downstream Upstream
Connection Speed 9470 kbps 1023 kbps
Line Attenuation 280 166
Noise Margin 86 db 66 db
The guys at Xilo haven't solved this, all they seem to be able to do is pass it back to C&W and tell me how much it will cost to send an engineer out. So I doubt they will have any problem with me asking here: "what would you do" ?
edit: I should add - I've been using : http://speedtest.uno.net.uk/ to test my speed (but others concur).
MTU was set to 1500, which offered marginal speed improvement, but was advised by Tom@xilo to change it back to 1432... which is where it is at.
There are no other lines/phones/extensions in use in the flat
Updated router firmware to 1.06c
Although slow the connection seems stable (i.e. I think I've seen up to 8 days connected, but with all the tests its hard to tell)
