every time i start a download w/ dial up, the first few seconds it has incredible speed (for dial up) around 20-30 kB/sec. after few seconds it settles on 3-4 kB/sec and just continues like that. does anyone know why does this happen and is there any way to maintain the speed on around its original throttle.
Even if it's displaying 20-30 its most likely still downloading at 5-6, when i had dial-up 9 kb/s was the maximum. Thats the normal speed for dial-up. You could try Download Accelerator (thats what i used) http://www.speedbit.com/DAP7/Default.asp?
btw: DAP has spyware so i would scan with ad-aware, spybot etc after installing it. Thats what i did and didnt have problem after that, worked fine.
thanks WiskiC for reminding me of the spyware in it.
No Problem, ©opy®ight...
Also, I've always been skeptical of download accelerators - I mean, 56K is 56K... I've not seen significant results using any download accelerators in my own experience, and they are almost always loaded w/ malware... In the end, most will end up slowing your connection even more...
If you're forced to use dial-up, may I suggest d/l and installing Mozilla Firefox, and using the pause/resume features in the download manager (pausing while surfing, etc., and then resuming all when you get off the computer...)

EDIT: To answer the *original* question - no, I'm not sure why that happens, but I know that it happens on most dial-up downloads (I know it sucks, too - "Wow! 30K/sec!!! oh... damn... back to 1.15... :( ). But, no - there isn't a way to keep the d/l rate the same... If there were, I doubt many would have switched to broadband in the first place...
this is someting i have noticed for years w/ many different browsers and many different OS's...
it must be something else
i really think it's downloading at that speed (at the beggining) since you can see the file actualy getting bigger. if you have a dial up try it right now w/ any file and notice the download window. if you don't use dial up try metconnect for free to test if you want
Hi unhappy, your speed settles at 3-4 KBPS but mine starts at 40-50 for the first few sec and comes down to 1-2 in evening and 6-7 in the morning. It don't know why we call it 56k.
Tip1: For best results, download exclusively. I mean stop surfing the webpages.
Tip2: If you want a *superficial* speed boost while downloading(in DAP). 'Suspend' the download for few mins and then 'Resume'. Your speed will be then 30-40 but it will decrease gradually. (won't work if you are using a GPRS).
Hi Wiski, how about making Download Manager(firefox) and DAP compete. Try downloading the same stuff with DAP and the other. See the results yourself.
My ques to broadband users-Is your speed stable?
cheers!!
My ques to broadband users-Is your speed stable?
um nope. mine starts around 900 and stops around 600 on a good server....
ok ... since everyone agrees ... do you have any idea why is the speed higher at the beggining and how to keep it that way
"uncapping the dial-up"
Don't forget to divide by 8, or multiply if you are going the other way. The 56.6 is bits, but your download rate is bytes.
You will be lucky to get a connection much better than 50kBbits/s due to the quality of your telephone connection, and your true download trate is unlikely to exceed 5Kbytes
If you readings are higher I would say they are false.
I have a theory (based purely on surmise and guesswork) that it is something to do with how the dial-up connects. If you look at a phone cable you will see that there are more wires than you actually need. One of them (I think it is the blue one over here) is only used when the initial connection is established (the telephone equivalent of SYN/ACK).
Now a few years back, there was talk over here of using that wire to provide what was described at the time as "mid-band" internet at a speed somewhere between dial-up and broadband.
I don't know why this connection is faster, only that it is, and that might explain why you get a sudden burst of speed at the beginning?
If you have a very bad connection, you might get your telco to increase the gain on the line......... that would speed it up a small amount.
Remember that there have been no improvements on 56.6 in the past 5 years, so I guess that is the limit for that technology.
No, it is not capped as such, and no you cannot do anything about it :(
in us there are actualy 4 wires
hmmm ... gotta do some more reading on all this
Like Nihil said 56k is 56.6kbps = 7,075 kBps ... ofcourse this is only theoretical max speed.
Don't forget parity bits, errors, retransmitions etc.
In my contry we use only two wires, and I have the same thing when starting download over dial-up. It doesn't matter if I use IE or DAP.
Here is my theory:
when you start download, while you point to folder where it is going to be saved, download engine (or whatever it is) is buffering that file somewhere in RAM or TEMP file. When you click on SAVE that buffered data is transfered to it final destination, and you have high speed displayed. After that you have the real speed displayed. Actualy I guess that this speed is calculated with difference in file size measured after predefined time interval.
In DAP, when you click on SUSPEND, download is not stoped. It uses extra bandwith (that is not used for browsing at that moment, for example) to buffer data. When you resume, the same thing happens, you have large data flow to file on disk from some temoprary storage/buffer (probably RAM) and high speed calculated. I think this is only marketing trick.
I use download managers only because dial-up has tendency to brake connection, so I can resume download. Or if I'm geting large (101MB for example) file, I can do it for several nights. there is no speed increase.
56k is 56k.... everything you see above 6kBps is only illusion
Hi, unhappy
This site has some good information and tools for measuring your upload and download speeds :)
Browse around, there is other useful stuff on the site as well
http://www.pcpitstop.com/internet/Bandwidth.asp
EDIT: Further thoughts.................whilst you are downloading there must be a fair bit of handshaking going on? which means that you are uploading as well. So if the computer sending the packets is not getting acknowledgements fast enough, it will presumably slow down to a rate where it is?
Also, your 56.6 modem is asynchronous, in that it will only upload to a maximum of 33.6. I seem to recall that the theoretical maximum upload/download for a 56.6 modem is around 64kbps, so maybe there is some sort of load balancing going on within your modem?
IIRC 28.8 modems did not display this? and were certainly synchronous, and had a total capacity of less than 64kbps. Also I am using dial-up ADSL now, and find that the downloads tend to accellerate to begin with then settle down, rather than the peak and rapid decline when the download starts.
The reason it starts at a much higher speed is the way downloads work. Once you click a link to download, it starts to download the file. Then it brings up a save to dialog box where you select where you want to save the file. Of course, the files is already being saved to your disk in a temp location. Then once you click save it starts computing download speed. At this point you may already have 50-100k. This means when the clock finally starts, you've downloaded 50k in 0 seconds. Of course once it starts ticking this evens itself out to the real download speed.
use it to speed up your internet connection:

I'll agree........... IT IS JUST SHOWING............................. Dial ups have slow dl speed...................Quote:

It doesnt matter what dial up ISP you have. FCC regulates that the highest connection speed (in the USA) you can get through a standard rj-11 (phone line) is 53.3bps even though your using a 56k modem you will NEVER connect at 56K. Now you could try using an ini string for your dial up modem. These help a lot. For example if you have a 56k v.92 lucent modem you can enter AT&F+MS=V90 this will allow the modem to connect at the fastest speed possible while using the v.90 protocol, also could even use the Modem on Hold feature that comes with v.92 modem (if your running v.92) I used to be a dial up technical support specialist for the ISP I work for since 2002 now do broadband connections. If you need any help in programming the modem just me know . using an INI string would fix this issue.
I agree with ikalo, it is just the buffering thing that make it as if it was faster at start. It is base on the amount of data written to the hardisk/ amount of time taken. First few block usually big and within short period of time.
I don't really believe in download speedup program. I believe for these program to really works, some kind of compression have to take place (or proxy). The tranmitting end must compress the data before sending while your speedup program understand how to decompress it and save it to a file. Unless it is using bit-torrent type of proxy.

where would i put this ini string
hi unhappy, try this one too atx0s10=254. This will prevent you from being disconnected.
goto CP > Phones and Modems > Modems Tab > Select your modem and click properties > Advanced tab > look for "Extra initialization commands" and enter the string there > Click ok.
Note: You may need a restart.
Cheers
Care to elaborate ? What does it do ? i never tried those so i dont know much of the meaning.Quote:

I know how you feel i had that same problem and now i can maintain my speed burst by using a cable modem.

hello ©opy®ight,and Check out these links :Quote:
Modem Initialization Strings
AT Commands & Initialization Strings
In order for a modems to work properly it must be configured. Modems are not the dumb devices that most people think they are. This is because operating systems like Windows 95 and Windows NT typically hide all of the modems configuration commands used to configure a modem. It is important to understand the basics of configuring modems, so that when problems occur within initialization strings or chat scripts, you can interpret their commands.
The very basic commands used to configure and troubleshoot a modem are from the AT command set. The AT command set was originally developed by Hayes to work with their Smartmodem 300.

All modem strings below will work for internal dial up modems. Based on chipset of course. These will work on LUCENT, USRobotics, 3COM, BCM, Zetodragon, conexant, but Not external modems.
The most common initialtization string used is AT&F which will reset the modem back to the orginal factory settings. Excellent for fixing error code 630 for windows based PCs. Please keep in mind when you do use AT&F you must reboot PC in order for the changes to take effect. Also, when you do reconnect double check the connection speed it will say the modem is now connected at 115,200bps. This is not correct of course. This reading is actually the reading from the motherboard to the modem in the PC. Novice people will really think they are connected at 115,200bps. :)
AT&F+MS=V34 <--- will force the V.34 protocol. Means the modem will not connect any faster than 34,000 bps. Used for troubleshooting error code 678 for all versions of Windows 95 to XP.
AT&F+MS=V90 <--- will force the modem to connect using the V.90 protocol and also, make it connect at the fastest possible speed by modem.
AT+PHM = 0 <--- Will enable Modem on hold if your running a V.92 modem. How do you know if you have a V.92 modem? Run a diagnostics test on your modem. You do this by querying the modem. The modem will display ATI1-ATI7 in sequential order. The different ATIs will let you know if your modem is v.92 or not. Also, please note in order to use MOH (modem on Hold) you need to have the modem on hold software which you can get through either the PC manufacure or the modem manfacture.
Hope this helps. Computernerd22
