The Buzios internet situation is a little bit of a mystery to first time travelers. There seems to be wireless coverage, and then there seems to be absolutely none at all. This is entirely due to the fact that Buzios is built around a rocky cliff, and this interrupts signal even during the best weather. To remedy this many hotels and internet cafes rent their own lines and then offer a wireless hotspot to visitors.
There are also various Buzious internet cafes dotted about the city where you can rent time on one of the computers to check your email. Typical rates are around R$10 for half an hour to an hour, but shop around because some of the internet cafes situated in the center of downtown charge premium prices for the use of their internet facilities.
Your best bet for getting online without hassles is to make use of the wireless connection offered by most hotels. Be aware however that some hotels do not supply a Buzios internet connection for various reasons, and you should always inquire about this beforehand if you need one. If you take your laptop, you might have to sit in the wireless hotspot in the lobby in order to get a decent internet connection, but this is not true of all hotels.
A lot of guest houses and bed and breakfasts now supply an internet connection which is either included in your stay or available as an optional extra. Be aware that Buzios internet prices vary tremendously so it is probably best to find accommodation that includes the use of an internet line or you could end up with an enormous hotel phone bill to pay!
Buzios internet is not exactly the fastest around, as high speed lines are not very common. However, a hotel's internet connection should be more than fast enough to check your email and browse, but forget about watching YouTube videos while you're on vacation in Buzios.
As for gaming, if you are serious about gaming while on vacation it would be best to find an internet connection that is directly lined-in, rather than a wireless connection. This is because the wireless coverage in Buzios is intermittent, and as all gamers know this makes for a very unpleasant gaming experience. There are not any local gaming servers but Buzios has a dedicated gaming community and the Counter Strike Source and Warcraft Battlenet servers operating out of Rio de Janeiro are always full of eager gamers looking for a challenge.
