thesnake Posted February 10, 2006 Share Posted February 10, 2006 Hi, i got adsl few dayes ago and am totaly new to thisi had to plug the hardware my self coz i live in a remote place for anyone to help..i have connected to the ruter but the speed is unstable and my download rate keeps craching and its never over like 22k(should be 30k) well maybe i can get some help here because my isp sayes every thing is normalfrom there part but the thing is my ruter is on fac defult mode and they sayi need to make the setup my self because they cant send anyone...ill give u my settings and you can tell me if i need to change the ruter fac defult settings or if i need to update firmware...in case one of you maybe using the same ruter as me...i have zte adsl ruter on 192.168.1.1 my ip adress 192.168.1.2am using ethernet card. is the defult settings for my ruter ok?? or itneeds to be modefiedHuh Quote Link to comment Share on other sites More sharing options...
Andrew Posted February 10, 2006 Share Posted February 10, 2006 You should have a part number on the product.Do you know which one it is from the website?Other than that, I don't know what to do as I don't have that kind of router. Quote Link to comment Share on other sites More sharing options...
thesnake Posted February 10, 2006 Author Share Posted February 10, 2006 i have zte zxdsl 831A ( modem or ruter device. or what ever its called) as i see it on the device.my router page looks like the (ZXDSL 831 v4.2) on portforward web sitethe adress is (192.168.1.1) my ip is (192.168.1.2 )am using (D link) ethernet lan card..i dont know anything eals exept that the ruter has been reset to fac defult andits not updated (if it needs to) Quote Link to comment Share on other sites More sharing options...
gryphon Posted February 10, 2006 Share Posted February 10, 2006 Not to dissapoint you, most home/small office routers don't have any option to customise them for speed. Nor whould they need one.If you get 22k out of 30 I don't think that's to bad. You almost never get full speed as you should. Quote Link to comment Share on other sites More sharing options...
thesnake Posted February 10, 2006 Author Share Posted February 10, 2006 well the thing is i was using the usb port when the isp configuerd my router coz i didnt have a lan card...i jus wanted to know if i need to change anything at the router now that i am on ethernet card thats my main question that i supoose u could know by defult if i need to do anything..or is it the same for ex at setup page it sayes am connected on (ppp over atm ,pppoA) right under it there another choice (ppp over ethernet,pppoE) which one i chould use??? i tryed the secound choice 2 dayes ago and my dsl disconnected for 24 hours Quote Link to comment Share on other sites More sharing options...
gryphon Posted February 11, 2006 Share Posted February 11, 2006 pppoa is for connections to the internet over a analog telephone line.pppoe is for connections over an ethernet / network line to the internetYou probably need pppoa as you have DSL over a analog phoneline I recon ?

thesnake Posted February 11, 2006 Author Share Posted February 11, 2006 yes.. i guess leave things like they are..i somtimes even have over 25k download speed Quote Link to comment Share on other sites More sharing options...
erjin999 Posted February 11, 2006 Share Posted February 11, 2006 Dont forget to uninstall the USB modem drivers, thats all I can say ;)I am shure everything else is working well. Quote Link to comment Share on other sites More sharing options...

Phoenix Posted February 14, 2006 Share Posted February 14, 2006 at setup page it sayes am connected on (ppp over atm ,pppoA) right under it there another choice (ppp over ethernet,pppoE) which one i chould use??? i tryed the secound choice 2 dayes ago and my dsl disconnected for 24 hoursWell it could be that your provider blocked you because of illegal settings, which are considered hacking. They block you for a certain amount of time, and then when you can try again, it occures again, they will probably block you till further notice...But dsl is usually PPPoA.

thesnake Posted February 16, 2006 Author Share Posted February 16, 2006 so we can say this as a statstics: if 56dialup con give u about 5 k download speed then an 256dsl con wil give u about 25k download speed at an avrege of 1 for every 10,,,, is that true? this is haw we mesure it? that means a 1mb con should give a download speed of 100..right?

Phoenix Posted February 16, 2006 Share Posted February 16, 2006 i have a 6mbit connectionthis comes to a avarage download speed of 600 kilobytes per second.normally you divide by 8 because 1 byte is 8 bits so a 56 k modem has theoriticly a speed of 7 kilobytes per second. but because you never get the full speed it would be around 5 indeed..so a 1 mbit line (1024 bits per second) will let you a speed of 128 kilobyts. But because that maximum speed is never made, you will indeed download at a speed around the 100 kilobytes per second.. Quote Link to comment Share on other sites More sharing options...
gryphon Posted February 16, 2006 Share Posted February 16, 2006 one small error in your calculation, you have a parity bit which isn't used for data. So your speeds is correct although you don't get that much effective data in when you download. Next to that your ISP overbooks your line which results in slower speeds depending on how much you are overbooked. Usually 1:50, or 1:10 for a more pricy connection.Next to that the internet routers of your ISP and the country you are in. Believe it or not but when every one in my country logs in on their breack from work the internet slows down. And the site you are visiting, if the server you request a webpage from has another 20.000 connections at the same time your download speed will also be slower.Hence you never really have the speed you are paying for ;) Quote Link to comment Share on other sites More sharing options...
Phoenix Posted February 16, 2006 Share Posted February 16, 2006 I didn't notice that because it would get TO difficult to understand for sp1cy..but ok..little note on your 20.000 connections at the same time, thats where Content Switches and load balancers come in :Pbut yeah the line is usually overbooked..unless you pay 300 euros a month for a 1:1 1 mbit sdsl connection...

thesnake Posted February 17, 2006 Author Share Posted February 17, 2006 I didn't notice that because it would get TO difficult to understand for sp1cy.. u are totaly correct on that one.. but what i did understand is that what i said is correct for an 256k con u get an avrge download speed of 25 to 27 not 32 as it should be by the calculato.

thesnake Posted February 18, 2006 Author Share Posted February 18, 2006 A: In data communications, a kilobit is a thousand bits (1,000) bits. It's commonly used for measuring the amount of data that is transferred in a second between two points. Kilobits per second is usually shortened to Kbps (or kbps). For example, 1500kbps is 1,500,000 bits per second. 1 bit (b) (0 or 1) = one binary digit 1 kilobit ( kb) = 1,000 bits 1 Megabit (Mb) = 1,000,000 bits 1 Gigabit (Gb) = 1,000,000,000 bits To find your theoretical download speed for your line, divide your advertised speed by 8: 1500kbps / 8 = 187.5 KB/s or by 10 to include overhead: 1500kbps / 10 = 150 KB/s.............................................................copyed from dslreport web.....so dividing by 10 is rong from math point of view but correct as a final resolt Quote Link to comment Share on other sites More sharing options...
erjin999 Posted February 18, 2006 Share Posted February 18, 2006 Actually, as binary numbers are base two, the whole numbering is 2^x, so a 1kb is 1024b not 1000 (2^10). But for simplicities sake, many people accept 1000. Quote Link to comment Share on other sites More sharing options...
gryphon Posted February 18, 2006 Share Posted February 18, 2006 you know I wanted to post that this morning to. 1000 bits don't equal 1 kbits.1024 bits equal 1 kbits. For the weird reason erjin99 mentioned kilo, mega .. are not factors of 1000 but 1024.I just wonderd why dslreports (which usually has good explenations) whould have the info you quoted. :) Quote Link to comment Share on other sites More sharing options...
erjin999 Posted February 18, 2006 Share Posted February 18, 2006 Its not unusual for people to use 1000b=1kb for simplicities sake. I am not familiar with that website to say whether it is out of character for them to simplify it like that though... Quote Link to comment Share on other sites More sharing options...
thesnake Posted February 19, 2006 Author Share Posted February 19, 2006 i was recomended for adsl report by guys at pcmechanics forums to tweak up my networking settings it is a very good web and they have a very good tweak test and tool as for the qouted part it is in the faq section and i didnt copy it from a message at the forum allow me to provide a direct link to the q&a http://www.dslreports.com/faq/tweaks/6.+Speed#2606 this is an answer on a question on haw fast can u get on a dsl but either way this dont effect what they mean to say whitch is u lose 10 to 20 % of ure speed to overhead offcorse this is new to me coz i am new to dsl and i was expecting to have somthing like 30k for download speed but now i have only 26 to 27.. but i must say after i used that tool (DR TCP) well the download speed meeter is the same 26k but the files are downloaded faster even in multi player games i noticed improvment maybe due to stabelty and reduce packet loss.. chek it out Quote Link to comment Share on other sites More sharing options...
thesnake Posted February 20, 2006 Author Share Posted February 20, 2006 anyway i would like to ask u should i use this tool http://www.dslreports.com/drtcp to setup my, RWIN (TCP Receive Window). and mtu? would that tweak be usfull with my settings....?

Phoenix Posted February 20, 2006 Share Posted February 20, 2006 I'm not quite sure about tweaking your MTU..Because if you set your MTU to high, your connection can get very slow, because of packet loss. If this occures, with TCP it will be retransmitted. So if there is packet loss and you have a high MTU value, that entire packet needs to be retransmitted. Causing your network to become slow.MS windows 95 there is a MTU of 1500 set in the registry.Microsoft advises a MTU of 576 bytes for an internet connection. Since windows 98 this is the default MTU.I think the default MTU is good enough. You won't notice the difference. unless you set your MTU to some huge values..Than you will notice your network to get slower and slower..

gryphon Posted February 20, 2006 Share Posted February 20, 2006 I agree with Phoenix. With a 30kb internet connection you are not gon'na notice the defferance . . if any. Quote Link to comment Share on other sites More sharing options...
thesnake Posted February 20, 2006 Author Share Posted February 20, 2006 haw about my RWIN (TCP Receive Window).. dose tweaking that make any deffrence? i dont understand what u said very well do u think i must not use the tool at all? and if i do can u tell me the value i should use for the mtu and rwin please.. thank you Quote Link to comment Share on other sites More sharing options...
