Hi there Sandra !
Fantastic to have you on the show today - thanks for calling in

Righto - it sounds like you have two problems running, so I will tackle the computer standby problem separate to the slow Internet...
Computer Standby: As I mentioned on the radio today, there are a few different systems that can send your computer into standby mode, so what we need to do first is work out which system is sending it to sleep. (then we can change the correct settings!) I would suggest that you go to your windows control panel (Start , Control Panel) then look for your power settings icon. Use the dialog box to change all the settings to "never" go to sleep. (ie. Hard Disk, Monitor, Computer etc... )
If you would like more detail on how to do this, I need to know what version of Windows you are using I can run through the specific steps.
Slow Internet: This one is a bit more complicated, because it can be sooooo many different things. Anyway, to start with I would need a little bit of information:
1) Your computer age (roughly will do)
2) Your operating system (eg. Windows XP, Vista, MacOS etc..)
3) Your browser name, and version. Open your Internet Browser and click on "Help, About" and note the name and version number
4) Lastly, try downloading a test file for me and note the time it takes. To do this, close your email programs and any other Internet programs (other than this browser of course!) and then click on
http://mirror.internode.on.net/pub/test/10meg.test and time how long it takes to download the file. Yes, it's safe to download and No - it doesn't do anything... it's a dummy file.
Let me know how you go,
Cheers,
:)RG
