Will I benefit from an 80\20 Upgrade?


[link to this post]
 
I currently have a 40\10 FTTC connection that gives me about 37Mbps down and 7Mbps up on a line that is about 1.2 Km long from the cab. I realise that at this line length I am lucky to get anything close to these speeds.

The router shows the following stats

# xdslcmd info --show
xdslcmd: ADSL driver and PHY status
Status: Showtime
Retrain Reason: 2
Max: Upstream rate = 7737 Kbps, Downstream rate = 40732 Kbps
Path: 0, Upstream rate = 7197 Kbps, Downstream rate = 36919 Kbps

Link Power State: L0
Mode: VDSL2 Annex B
VDSL2 Profile: Profile 17a
TPS-TC: PTM Mode
Trellis: U:ON /D:ON
Line Status: No Defect
Training Status: Showtime
Down Up
SNR (dB): 4.8 6.9
Attn(dB): 0.0 0.0
Pwr(dBm): 13.0 4.7

Looking at the stats it seems to indicate that the max downstream rate is 40732 Kbps and 7737 Kbps up.

Are these figures likely to increase if the line is re-graded to 80\20 or is that the maximum I am going to get on Profile 17a regardless of what the advertised max speed is?

I only ask because I don't want to get stuck in an extended or more expensive contract if there will be no benefit.

Not worth it.

All you will achieve is one or two Mbps more on your download while lowering your already low SNR even further.

That and the fact you'll need to start a new contract.

I suppose it depends on how much of your contract is left and if you don't mind staying with BT for another 18 months. Its possible that within the next 18 months 30a profile might be available so an increase will then be seen straight away without the wait of being upgraded to see it.

Line is already using profile 17a if modem data is right, so probably no change.

I'd leave things as they are for now

That's pretty much what I figured but it's only because I've used an "unlocked" firmware that I'm even able to see the maximum achievable speed on the router.

There must be loads of people who think that they will be getting significant upgrades when in reality they will get very little and then be tied to another long contract and possibly paying more as well.

Should be an estimate given at upgrade time hopefully

Just hacked my modem to see if it was worth the upgrade for me , can one of you kind folks help interpret this info , am I likely to see much of an increase ?

OTOH:
Down Up
SNR (dB): 10.1 6.3
I'd have thought there was scope for a bit more downstream speed there?

I'm guessing that would account for the 8 or 9 Mbps increase?
