With the use of wireless increasing with more and more devices connecting to the internet. Good home wireless is a must. In some cases the wireless provided from your router is sufficient to give you good coverage at home. If you live in a bigger house or an older house with thicker walls that are typical in the UK, you might need additional access points. This will stop black spots or weak signal in your house. There are a number of ways this can be achieve, either with boosters or access points. The access points are smarter then the boosters and will offer more features and reliability. Down site is they require more to setup and manage. Booster can be a quick and cheap fix if you only a weak signal in a single part of the house.
