ADSL stands for "Asynchronous (or Asymmetric) Digital Subscriber Line." It is a type of digital internet communications carried over an analog line (POTS (Plain Old Telephone Service) or PTSN (Public Telephone Switched Network); they both refer to the same service). Typically, ADSL offers faster downstream communications and slower upstream communications, such as 8Mbit/1Mbit, which means the download speeds are eight times faster than the upload speeds (not including overhead and congestion).

3g is mobile internet and adsl is a type of home internet so adsl is better
Dialup is slow, ADSL is fast

For troubleshooting tips for your adsl modem you can read about go to support.hubris.net/dsl/troubleshooting.html. For more help you can go to www.eternalmart.com/tag/adsl-troubleshooting-speed/.
Speed is the difference between HDSL and ADSL. HDSL has high upload and download speeds whereas ADSL has a slow upload speed coupled with a high download speed.
ADSL is simply a version or 'flavour' of DSL. The 'a' refers to asymmetric, meaning 'not the same'. Hence, ADSL usually has different downstream and upstream rates (e.g. 1536/256 is a common speed of ADSL available in Australia, where downstream the link speed is 1536kbps and upstream is 256kbps).
I believe your Internet Service Provider must sell you this option. Once you pay for it your router should be working at the speed of ADSL. I am currently using ADSL, but will be going to a faster speed.
Yes, you have to have an ADSL splitter before your router to route the packets from the Internet. There are numerous router which have an inbuilt ADSL supporting varying speeds like 54Mbps etc etc. You can choose one from them if you do not want to have separate ADSL and Router installed separately.
Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission than a conventional modem can provide. A modem which can do such a job is called an ADSL modem.
