Not good after ADSL2+ upgrade

[simonbratt99]

hi

Anyone else not having a good experience after upgrading from ADSL2 to ADSL2+ (CN21)

Even though our router is ADSL2+ compatible and modulation set to the correct setting, got many ADSL drop offs, sometimes (10 drops in 15mins, sometimes fine for a couple of hours)

Had to go back to the G.DMT modulation for some slow stability.

Our BB was only 3mb anyway.

great im getting answers from Draytec to try other ADSL firmware codes namely

E.67.02.52  &  .55

Its unbelivable, its a lottery as to what ADSL firmware will work best!

So there are many manufacturers and many ISPs, that makes alot of combinations

Surely ADSL2+ is ADSL2+ or were all doomed!

So BT, what 'settings' are you using for my ADSL2+ so i can choose the correct ADSL firmware to match your ADSL2+

Or do you want me to keep trying other firmwares to see if one happens to match?

Wouldnt be so bad if testing took 10 mins, but last firmware i tried to 3 days to totally bomb out, on a Sunday night, which required an office visit by me to swap routers to the old settings.

Im getting a little annoyed.

Hi Simon,

I chased this up earlier and am currently awaiting a reply, I will update when I have a response.

another day gone, we are a business, and not a 2 man band (not that they arent just as important)

This should be answered same day, not a week later.

I think we have been patient

thanks

Hi there,

The vigor 2800 does seem to have some bad press related to it's ADSL2+ functionality.

Try here for the 3.3.4 firmware which you don't seem to have tried yet I don't think?

Thanks

** on further reading this version has it's own problems, might be worth a try but I'm still reading a bit about it.

Hi Simon,

Just got a reply to say that the issue is getting looked at right now.

Hi there,

The 2800 seems to have an issue with INP (Impulse Noise Protection) or Interleaving which has 5 settings, off and INP1, 2, 4, and 8.  There are a few posts were it's suggested the 2800 doesn't support INP2...whether you are on that by default I don't know but I'm trying to find out how to check.  But the problems with this seem to match yours.

So you could call BT tech and request that interleaving is turned off, a fault would need to be raised to wholesale to get this done for you but tech do definately do it.

You could also try the new 3.3.4 firmware and change the modulation setting to Annex M, some users have reported better performance and stability with this setting, even although the ISP doesn't support it.

Here is a link to the supported firmware for ADSL2+ in the UK, its V2.8.2...I think you mentioned it earlier though.

Heres a link to some interesting forum posts on drayteks site (you have to sign up but its worth it)

Thanks

Appreciate the replies.

I see no 3.3.5 firmware, nothing new from when i started looking 2 months ago

Im not looking for better performance, im looking for a signal that stays ON, that doesnt drop 20 times a day.

I havent even got to the performance yet.

Clearly ADSL2+ upgrade was too early. Its not been tested enough.

it's 3.3.4 and I was talking about the dropping connection...the reason it's dropping is because the router can't handle the higher frequency that ADSL2 runs on and is also incompatable with the type of interleaving that 'could' be on your line, the forum posts I linked should back that up.  Turning interleaving off may improve it...it's worth a try.
