Is speed in first 10 days of connection likely to continue?

I live in a village, which only has BT wholesale ADSL, capable of basic <8Mbs.
I was using Orange, and typically got 6Mbs
I just switched to o2, and get 6MBs at 2am or 10am, but as low as 0.3Mbs in the evening, all evening.
o2 say this is the stabilisation period of 10 days while they calibrate the kit, and I should wait until 10 days have passed before assessing this. Since it does 6Mbs every day at the quiet times of day, this sounds unlikely to me. Can anyone help?
I would have assumed they simply have too much contention in my village

thanks
Tony

I take it this is the O2 Access product? If so it is said to be heavily oversubscribed and you will continue to suffer low speeds at peak periods. This has nothing to do with the so called "training period".

You pays your money, you takes your choice. If you are within a cancellation period now is the time to decide on your priorities.

Normally I would not comment on Orange non-LLU, but if you were getting 6 Meg from it frequently, then I'd go back to it before your 30-day O2 Happiness Guarantee is up, in view of the very poor reputation that O2 Access has gained

thanks guys, I am in the 30 days, so I intend to cancel unless something dramatic changes, I didn't think the variation each day could have a nice reason.
Do any other ISPs have better reputations in villages? (when I moved here from NTL cable I had to get satellite-broadband for more than a year - there's only 500-750 lines here even now) I had such a lousy time with customer service on orange last year when there was a line problem under the road (that they insisted was inside my house), that I would prefer to go to another ISP if possible. I buy large software libraries every month or 2 that can be 1-20GB, and they came in from the Orange ADSL at the speed I would expect whatever time of day it was. I had pipex before, they were OK I think. With the current o2 performance, even web surfing is painful. youtube sticks, etc.

I didn't realise there was such variation, they are all around £20 a month for me here, so I thought the contention would not vary so much

Yes, that's the downside of Orange; atrocious customer support, but if you can manage without it ... better the devil you know?

hmm you may have a point. The Orange iPhone/broadband tie in deal has an attractive price for me - and so far o2 have failed to send me my new refurb iphone 3gs..... I bet they send it before I get a chance to think further........

your sig got me thinking - I started at home with unet in 95, didn't need much bandwidth then!
SHame I cna't get a faster line in the sticks, but it's my own choice. The week I cam here with loads of subs on an NTL cable in 2001, and switching on 56k dialup after teh 1 week move was a reality check - took about 2 days to get my emails!
