Dial-Up speed problem! Need expert advise.

by karansawan / December 22, 2008 12:01 AM PST

Hello everybody,

I have a simple problem (well, not so simple actually).

I have a dail-up connection which the I.S.P says is 75kbps.

Sometimes, when I start a download by using any download accelerator or with browser native download manager, i get a speed of around 165 kbps and sometimes even above but with each second, it comes down and becomes stable around 7 or 8 kbps.

Why cant the speed remain stable around 165 kbps?

I have a UTStarcom UT-300R2 modem with Reliance Broadband connection in India.

Please tell me any solution.

I am an expert guy so if you want me to tweak some advanced settings or anything lke that, don't hesitate.

Any help would be appreciated.

The answer will not fit into this space.

The "burst" speed you see can't be maintained. It's all about the data and how things work. I can't find a way to compress that into this small box but as it is, what it is and more all looks good from here.

Still I have a doubt.

Hi friend, actually I posted this thread because I have seen people recieving great speeds like 300 kbps on theri dial-up connections.

So, I wondered why can't I? Especially, when my connection has the ability to reach that speed.

Still looking for solutions.

By the way thanks for your advise,

You may have to ask them what modem they used as well as any 'accelerator' they use. There is that old PROPEL software that compresses on the server side but that is far too much to type about here in this small space.

56 kilobit (UNCOMPRESSED!!!) is the norm, what is supported and you will see multiples of that under the right circumstances with uncompressed data.

I'll stop here as only those that don't want to research this area will keep asking.

Let's try real simple.

Let's say you move a ZIP file across your dial up connection.

If you had software to unpack that and push the unpacked content across the virtual serial link, you could see a higher bit rate than what the actual link supports.

Hopefully this is enough of an explainer why you see bursts of speed. It's almost a bad decision to report these speeds to the end user since it most often ends badly with some feeling hurt over having to learn so much.

Dial Up?

You are using a ADSL modem, so it's really not a DialUp connection. In my understanding, DialUp refers to connecting thru' a normal phone line and the speed is <= 56 Kbps.

Your ISP says it's a 75 Kbps link and expecting it to perform continuosly at higher speeds is not possible.

Your friends may be getting higher speeds either because of a different plan of the ISP or a different ISP like BSNL which support speeds upto 2 Mbps.

Your ISP says your link is 75 kbps ans one cannot expect higher speeds persistently, only occasional bursts.

Friends getting higher speeds may be because of a different plan subscribed to or a different ISP.

Dialup connection speeds
by ghettovision / February 5, 2009 1:23 PM PST

Dialup internet access has a max speed of 56kbps so if you think you are getting faster speeds not posssible, especially in india as it has poorly maintained phone lines. If you have ADSL (unlikely as only 5% of the phonelines in India would be capable of supporting dsl) you should call you isp as you has a issue with the dsl connection.

After further research the modem you stated in you post is a ADSL 2+ modem with a max speed of 25mbps on a ADSL 2+ equipment. Your issue of unstable speed connections means you could have a couple of problems, most likely poor line quality, bad adsl equipment, failing modem. I would suggest you call you isp as there is no tweaking that you can do to a dsl modem to increase you speed or stablize it as bandwith is controlled by the ISP.
