Re: Netgear DG834G v3 - compatible with ADSL2?


[re: john2007] [link to this post]
 
Changed to ADSL2+ and rebooted.

Current stats now as follows:

ADSL Link Downstream Upstream
Connection Speed 6492 kbps 440 kbps
Line Attenuation 42 db 13 db
Noise Margin 9 db 19 db

My Broadband Speed Test

Presumably this means I am definitely on ADSL2+ kit and therefore AOL should be able to put our line on a higher upload profile?

An indirect way may be by looking at the bit allocation table.

# cat /proc/avalanche/avsar_bit_allocation_table

I'm afraid it sounds like it. Could you try

cat /proc/avalanche/avsar_bit_allocation_table

and paste what it reports?

p.s. you'll need to enable debugs again.

Re: Netgear DG834G v3 - compatible with ADSL2?


[re: wannabemedic] [link to this post]
 
OK.

I'm stumped. If all the downstream lines above the 16th were zero I'd have thought ADSL1. If they had similarly random figures to the first 16 lines I'd have thought ADSL2+. However they have a sort of pattern of 00, 40, and C0, as if they are left over values of a start up RAM test.

If you compare my upstream figures to yours though I'm afraid I can't see your upstream improving much.

Bear with me. I'll see if I can correlate your bin figures with your sync rates. I may be some time though.

Hopefully someone with a better understanding will post.

No problem, I really appreciate the help from everyone on here.

I've sent a complaint to AOL for the tripe they churned out on the phone yesterday, about BT being responsible for the upload speed and AOL being responsible for download. Makes me wonder how someone could make it into public-facing tech support with that level of knowledge!

Re: Netgear DG834G v3 - compatible with ADSL2?


[re: wannabemedic] [link to this post]
 
Didn't help much. E&OE!

Upstream I have 293 bins, downstream 2591.

Each bin should realise 4000 bits per second giving 1172 kbps up and 10364 down.

In general terms 1Mbps up and 10Mbps down.

I stopped there as I know my line will reach 17Mbps down. To me this indicates that the bit allocation table is used to show the tones in use, not the tones which could be used. Which makes sense.

No further forward I'm afraid.

Sorry, a bit of a red herring.

I'm pretty sure you are still on G.DMT from the upload sync and that your attn. not increased.

In reply to a post by wannabemedic:
I called AOL Tech Support to ask about the upload speed, I was told that whilst we have AOL Talk and AOL Broadband, because our line is provided by BT, I have to contact them about the upload speed. AOL say they are only responsible for the downstream speed.

I expressed surprise and was told that it was because AOL were providing broadband over BT's line.
Are you aware that to take the AOL 24 Meg product (the "boost" presumably) you have to move your line and line rental to AOL and away from BT? It's Full LLU. Or is the "boost" a special for existing customers on AOL's 8 Meg Partial LLU product?

Have you been "boosted" yet?

Re: Netgear DG834G v3 - compatible with ADSL2?


[re: RobertoS] [link to this post]
 
Eureka! I've discovered some useful info about the Netgear DG834v3 's ADSL Mode (it's something you've seen before a year ago but have forgotten) while I was looking into another AOL LLU speed query.
In reply to a post by wannabemedic:
Trained Mode: 16 Selected Mode: 1
16 means ADSL2+; it would have been 3 for G.DMT.

AOL basically offers 2 BB products: 24 Meg Full LLU (a la TT) or 8 Meg Partial LLU. All the stats I could find here on TBB for the 8 Meg product have Upstream Speed = 448 kbps. So, I'd been thinking that AOL was running G.DMT on their 8 Meg LLU, but now I suspect that they are running 8 Meg capped ADSL2+ with a sort of ADSL Max profile.

The OP's various reported stats all show the same Upstream Speed of 448 kbps, no real change of Attenuations and just a bit of variation in Downstream Speed as he plugs into different sockets. So I deduce that he has been on ADSL2+ throughout and that the "boost" consists of just removing the 8 Meg cap and we will not see any increase in Attn. that we had expected.

It is said that AOL & TT share the same network, but we can see that they package their products differently. I suppose that AOL can install a diff DLM in their exchange kit to achieve this?

Does that make sense?
