Do I really need Max?

[deeshow]

Hi to all,
I was so pleased to find this site. Thanks to the wealth of information here I have gone from a non-working ADSL to a fully working one in a couple of days. Whereas up til then, since my activation I have had almost 2 months of impaired operation and countless phone calls to Sky technical support

I would like some advice on my current connection which is sky max. Do I really need it? Would I suffer any speed loss if I moved to the mid package? My attenuation figures are 53dB, so I am a fair distance from the exchange. My current sync rate is about 4000kbps and my upload is 416kbps.

Can I get any better than this? I have installed an ADSL nation faceplate and I have tested at the test socket and there is no difference in my stats. I have also run the TCPoptimiser and found no difference. My stats are as follows:

I have run speedtest.net Also tried a FTP transfer of a 600MB file. This gave transfer rate of 430kBps or 3440kbps so they correlate pretty well.

My errors were pretty low but as I am on GDMT do you think I have been capped? If I could put up with the 40GB download limit would I be better off on the Mid package as I won't be able to ever get anywhere near 8Mb speed let alone 16Mbs!

Any advice would be greatly appreciated.

You probably have a high number of errors on your line which is why sky put you on G.DMT in the first place, asking to be put on ADSL 2+ just might make matters worse, I advise you to downgrade to mid package.

Could any one let mw know how I can get those figures? And how I can recognise the distance from the local exchange?

I have the same issue here.

I'm on Max, but only get 6016 kbps & 416 kbps. And I'm also on G.DMT mode.

If I want to downgrade to Mid package, should I just ring up Customer Service? What if they refuse my request? When I signed up to Sky BB, I was told that I can't downgrade it within 12 months

Based on what I've learnt from this site (hehe) you're better off on G.DMT bcos your attenuation is quite high and going to ADSL2+ may actually lead to a lower download speeds. You're not capped, simply limited by high attenuation (mine's 55db, so we're in the same boat).

My understanding from sky customer services is that you'll still be liable for the monthly subs for at least 12 months if you choose to downgrade from Max to Mid since you avoided the initial setup costs, however - and this is untested - if they sold you the max package on the basis that you'll get close to 16mb download speed at your address, you could have some scope to negotiate a downgrade or discount on subs.

Isn't it amazing what knowledge one can pick up from here... just 2 weeks ago I'd never heard of G.DNT, ADSL2+, attenuation etc

FrostFree:
Thank you for your reply!

24db and 55db, which one is better or stronger?

[FrostFree]

Remember that attenuation is a measurement of signal degradation or loss as it travels down from the exchange to your telephone socket, and it's an indication of how far you are from the exchange.

The lower the better, a line with 24db attn and 19db noise margin (which is good) should be able to attain download speeds in the region of 12mb on adsl2+, so the connection speed on that router is lower than I would expect which IMO suggests it's capped or on a G.DMT connection.

Also keep in mind if it ever shows 15db attenuation just reboot the router until it clears because that is a bug.
