Lohar people.

Posted here a while ago about my home connection constantly dropping. Its still doing it, and now im coming home from uni need to get it sorted ASAP.

Im with AOL at home, well, i say i, but really its my parents. Anyway, we had their platinum service, and then we were told we couldnt get 2mb because our line couldnt take it, so we downgraded to 1mb. Thats all fine, im paying for 1mb... but heres the problem, im receiving two.

Now if my line didnt support it, why has it been upgraded. My SNR margin seems to vary a lot in the day, and is a lot worse at night. If i keep letting my connection reset, IE, let the DSL refind itself, it will reconnect at 2.2mb. If i remove the usb modem, and let it reset entirely, it will connect at 1mb, however it will still download at 2meg speeds... which is weird i thought.

Is there any way i can get my line properly downgraded back to 1meg. I would much rather have 1meg than unstable 2meg as the constant disconnections are frustrating as hell on xbox live.

Any help would be much appreciated.

This bit is odd. Unless you've been regraded to Max, if you're on 2Mbps, it'll connect at 2272/288 kbps, or it won't connect. There's no rate adaption involved.
You might find you get better stability from not using a USB modem.

Phone your ISP?

Cheers for your help thus far.

Yes it does say 2272/288 and is always listed as that in the modem properties. However, upon connection with the network connection window, as i said, it can be either 2.2 or 1.0 depending on whether i have removed the usb plug from the modem to reset it or just let it re-find the DSL signal itself.

If it is the modem, how much am i looking at for some hardware to replace it. I only have this one computer and my 360 and dont need wireless, so some recommendations would be appreciated as im not up to scratch on routers etc.
 
Small, bed time bump. As far as i know im allowed to do this. Either way, would really like to get this problem sorted.. its ruining my xbox live experience with the ocuk lads!

Just sounds like a bug in the software if it displays 1Mb and downloads at 2Mb. The problem is it's set to sync with your line at 2Mb, so as has already been said you need to contact AOL to get downgraded.

~£50 for a new DG834?
It isn't hard to look at the shop for an ADSL router :p

Im ordering some bits from OcUK tomorrow on the off chance anyway. Should i invest in one of these routers?

I really like to investigate my product purchases fully but obviously dont have the time as i also need to investigate the UPS and backup HD im buying. Should i be considering some form of wireless too? My current demands dont need it so i doubt it as the technology will evolve and i wont be buying into it for a while i think.

<troddles off to ocuk routers bit>

edit: Thinkin about it the difference between wired and wireless isnt exactly much. But overall £50 is quite a bit for a shot in the dark at better stability of SNR isnt it? So im going to ring my ISP tomorrow. If they have absolutely no idea i will buy the router, if they can help i will see that through rather than purchase some new kit unnecessarily.

Might as well. Netgear isn't my favourite, but they have their..."fans".

If you're not going to use it, probably not.

Probably.
 
I'm not sure if the same applies with ADSL, but with MaxDSL, you can ask your ISP to get BTw to up the SNR target. I'd guess that a lot of ISP's won't be bothered to go out of their way to help you and get this done though :(
 
Max is running quite well on my line. Been sync'd for over 2 weeks now on a ST 510v4 :o SNR and error rates are not bad either.

Not surprising.
Expect the SNR margin would give you a fair insulation from any noise (though as an aside, I've noticed the SNR marign variation I see getting less recently).

Decent router helps too :p
 
My SNR is always around the 5-6db range (downstream) with an unbranded router. I also have a DG632 but it doesnt display these figures.

Is this way to low?

(AOL MaxDSL btw)
 
Yeah, syncing at over 6mbps but downloading slower than my previous 2mb. This is nearly a month into the upgrade too :(

Even emailed BT hoping to get an honest answer when i asked them what the hell is going on with the max service and my line, but they just shift the cause and tell me to take it up with AOL, who then refer me to some indian folk who know nothing what so ever. :mad: :o

And quite rightly so.

If you're into emailing other ISPs, you could pick from the list on ADSLguide. :p

"MAC key please" is always a good way to get the attention of someone useful.
 
Ha, the way things are going though, i may well be asking for my MAC code soon though if things dont improve within the following months.

/Prepares "What ISP" thread... :p
 
Well, ive had over 10 SNR all day so far today... Decided not to order a router just yet, been in contact with AOL and weirdly.. the woman kinda understood what i was saying about SNR.. what what? :confused:

Anyway, they are gonna perform some tests later and i get to speak to a senior techy..
