What Kind Of Download And Upload Speed Does Adsl Provide

[Nancie Morant]

Faster download speeds are great, but faster speeds mean more data traveling through your connection. Be aware if your provider has data caps, as a faster connection means you will hit those limits sooner.


Most ISPs advertise only download speeds, so you might not even realize that upload speeds are a separate thing. Download speeds are also generally the faster of the two speeds, so most advertisements tend to focus on them.

I seem to be getting 400 Kbps download speed here, and 700 Kbps upload (yes, they're both rubbish). Does this seem wrong to anyone, and what could be causing it (apart from the 'acceptable' things like distance from exchange etc.)


What upload speed should I get on a 4mb ADSL connection?



I've recently upgraded my adsl connection so that I can apply for an online job. The problem is that I need at least 512kbps upload speed. I've upgraded my connection from 1mb to 4mb and I'm still getting only 200kbps upload speed. Is this normal?






You'll have to check with your provider to determine what the upload speed should be for your connection.



ADSL is asymmetric which means that the upload and download speeds are not the same (synchronized). The internet provider will assign a separate download and upload speed to your modem based on the plan that you have subscribed to.



Typical the upload speed is signification slower than the rated download speed.


hello there , this is very common Qs among the adsl connection user,

I had the same problem when i switch to adsl connection this is what i found.



Yes In most of the cases it is normal for adsl connection to have slow upload speed because the isp assumes that most users send downloading req more (browsing) than uploading and isp have to send both voice signal for telephone and internet signal in the same line with fix bandwidth.



I have 2 mb/s bsnl broadband connection where my downloading speed is 200kb/s but uploading is only 50-60 kb/s.



hope this helps


depends on the isp or internet service provider. some isp provide higher or equal upload speed to download speed, most provide low upload speed comnpared to download speed.

Unlike regular dial-up copper telephone line service, ADSL provides continuously available, always-on broadband connections. ADSL is asymmetric in that it uses most channels to transmit downstream to the user and only a small part for uploading information from the user.


so i have adsl internet and my statistics are 14,60 mbps download 0.85 mbps upload can i increase my upload speed by changing some settings in the router or i can do something else?(router is ZXHN H108N V2.5)


Most ADSL is limited to about 1Mb upload, if you have ADSL2+ it may be possible to enable Annex/M which allows you to take 1 Mb of download and move it to upload. It does need to be enabled on both ends so talk to your ISP.


Broadband or high-speed Internet access allows users to access the Internet and Internet-related services at significantly higher speeds than those available through "dial-up" services. Broadband speeds vary significantly depending on the technology and level of service ordered. Broadband services for residential consumers typically provide faster downstream speeds (from the Internet to your computer) than upstream speeds (from your computer to the Internet).


Cable modem service enables cable operators to provide broadband using the same coaxial cables that deliver pictures and sound to your TV set, though you can still watch cable TV while using a cable modem service. Transmission speeds vary depending on the type of cable modem, cable network and traffic load. Speeds are comparable to or exceed typical residential DSL.


Fiber optic technology converts to light electrical signals carrying data and sends the light through transparent glass fibers about the diameter of a human hair. Fiber transmits data at speeds far exceeding current DSL or cable modem speeds. The actual speed you experience, however, will vary depending upon a variety of factors, such as how close to your computer the service provider brings the fiber and how the service provider configures the service. The same fiber providing your broadband can also simultaneously deliver voice (VoIP) and video services, including video-on-demand.


Satellite broadband, another form of wireless broadband, is useful for serving remote or sparsely populated areas. Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased, the consumer's line of sight to the orbiting satellite, and the weather. Satellite service can be disrupted in extreme weather conditions. Speeds may be slower than DSL and cable modem, but the download speed is still much faster than the download speed with dial-up Internet access.


I also strongly believe the government doesn't provide the greatest services not just internet, I mean even entertainment on Algerian TV channels is horrible, it really all seems like its on propose.


The reason for possible uncapping my upload speed? My son lives abroad and we installed a Slingbox so that he can access my TV. The upload speed of .46 is just not fast enough. He reckons we need at least .60Mbps. His picture is unwatchable at the moment. How do I go about getting the uncapping......and take my chances on it improving things.


Thanks for reaching out to us here, from testing your line today you are currently syncing at 0.9mbps upload so it wouldn't be capped. Are you noticing the speeds deteriorate over a wired or wireless connection?


Most ADSL/FTTC type connections are not synchronous and they have relatively poor upload speeds (which is what is required for online backup). Most also do not have any type of SLA guaranteeing uptime.


ADSL wont do it because of its slow upload speed so that size of data will take about 44 hours to complete for general ADSL. Leased line with the same upload as download is about the only way I can see you getting that amount of data moved in a reasonable time. A 10Mb line both ways in the absolute best case will see you at about 3 hours for that amount of data.

There are both technical and marketing reasons why ADSL is in many places the most common type offered to home users. On the technical side, there is likely to be more crosstalk from other circuits at the DSLAM end (where the wires from many local loops are close to each other) than at the customer premises. Thus the upload signal is weakest at the noisiest part of the local loop, while the download signal is strongest at the noisiest part of the local loop. It therefore makes technical sense to have the DSLAM transmit at a higher bit rate than does the modem on the customer end. Since the typical home user in fact does prefer a higher download speed, the telephone companies chose to make a virtue out of necessity, hence ADSL.


The marketing reasons for an asymmetric connection are that, firstly, most users of internet traffic will require less data to be uploaded than downloaded. For example, in normal web browsing, a user will visit a number of web sites and will need to download the data that comprises the web pages from the site, images, text, sound files etc. but they will only upload a small amount of data, as the only uploaded data is that used for the purpose of verifying the receipt of the downloaded data (in very common TCP connections) or any data inputted by the user into forms etc. This provides a justification for internet service providers to offer a more expensive service aimed at commercial users who host websites, and who therefore need a service which allows for as much data to be uploaded as downloaded. File sharing applications are an obvious exception to this situation. Secondly internet service providers, seeking to avoid overloading of their backbone connections, have traditionally tried to limit uses such as file sharing which generate a lot of uploads.


The telephone exchange can indicate a suggested SNR margin to the customer's DSL modem when it initially connects, and the modem may make its bits-per-bin allocation plan accordingly. A high SNR margin will mean a reduced maximum throughput, but greater reliability and stability of the connection. A low SNR margin will mean high speeds, provided the noise level does not increase too much; otherwise, the connection will have to be dropped and renegotiated (resynced). ADSL2+ can better accommodate such circumstances, offering a feature termed seamless rate adaptation (SRA), which can accommodate changes in total link capacity with less disruption to communications.


In the early days of DSL, installation required a technician to visit the premises. A splitter or microfilter was installed near the demarcation point, from which a dedicated data line was installed. This way, the DSL signal is separated as close as possible to the central office and is not attenuated inside the customer's premises. However, this procedure was costly, and also caused problems with customers complaining about having to wait for the technician to perform the installation. So, many DSL providers started offering a "self-install" option, in which the provider provided equipment and instructions to the customer. Instead of separating the DSL signal at the demarcation point, the DSL signal is filtered at each telephone outlet by use of a low-pass filter for voice and a high-pass filter for data, usually enclosed in what is known as a microfilter. This microfilter can be plugged by an end user into any telephone jack: it does not require any rewiring at the customer's premises.
