If you're looking for a broadband package that is best suited to a busy family household with lots of people trying to get online at the same time, then there are a few key things that you might want to look out for. Getting a free wireless router thrown into the bargain is an obvious plus, as it means that everyone can get connected to the net without the need for you to run acres of ethernet cables up and down the stairs and into the various rooms where everyone's computers or laptops are. Other things you'll want to consider are security, speed and usage limits.
If you want the best broadband package for your family, the main things you ought to consider before thinking about speeds and usage limits and the like are things such as security and wireless networking equipment.
If more than one person in your family will be wanting to be able to get onto the internet as and when they want, then getting a broadband package which comes with a free wireless router is essential. Whilst most broadband packages these days admittedly come with a wireless router included, not all of them are available free, or are only available gratis if you meet certain conditions (sign up for 12 months, pay line rental, etc) so check the small print before you sign up.
Obviously in family households with younger viewers, security is paramount. Parents will understandably want to restrict access to certain websites, and disable the ability to download torrents and large file folders which may contain damaging trojans and viruses.
Again, the majority of broadband products these days will come with their own security software included as standard, but be aware that this software might not be compatible with everyone's computer set-up; not all providers will include software which caters for Apple Mac computers for example.
The busier your household is, the more likely it is that you'll want to consider a broadband package with a sizeable usage limit. Be wary of the fact that certain products with an 'Unlimited' usage cap will almost certainly come with a Fair Usage Policy and be sure that everyone at home knows that here 'Unlimited' doesn't exactly mean unlimited.
Find out what people in your home want; if people want to play games online, send instant messages, and make use of social networking sites, then you'll want to take out a heavier broadband package. If people will be using the net primarily for shopping, or school and college work, emailing and chatting and won't be doing anything more heavy duty than that, then perhaps a less expensive broadband package with a finite usage cap would be a good idea.
