2MB/s and 3Mb/s speed?

If you can tell me, can you tell me for both the speeds?

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

On the 2MB/s connect there should be no buffering at all, that's ~16mbit/s.. on 3mbit, you might see buffering..

Sorry I meant 2Mb/s

How much buffering can I expect on both? what I'm basically asking is, how long would it take to stream a 10min YouTube video at 720P?

One more question, how can I convert that into time?

Well the bit rate of a 720p video is 5Mbps with H.264 compression so you would get roughly 60% buffer time.

For example a 10 second video would be ~50Mb so on a 5Mbps connection it would load in ~10 seconds, but on a 2Mbps connection it would take ~25 seconds to load.

All these calculations do not factor in protocol, communications, etc overheads. In real life it'll probably take 10% - 20% longer.

Right now using a 1.9Mb/s connection and if I try to watch and stream then it won't work but if I let it buffer a bit first it only pauses a few times. maybe it will be even better once I get that master splitter installed!

Just to clarify, when I said 60% buffer time I meant 60% extra of the video length would be required just for buffering.

When you have a speed of 2Mbps, every Mbps counts.

A master splitter should help but don't expect miracles.

Well apparently, My line should be getting around 3-3.5Mb/s so yeah in this case every Mb counts.

If you manage to get 3.5Mbps you'll still have about 30% buffer time, though it's better than 60%!

LOL. It will certainly be bearable.

there are youtube plugins for browers out there, that will try to smartly manage your streaming, to allow for a consistent playback, after waiting till enough has buffered, assuming constant connection.
