Leap Wireless is currently in the process of developing a prospectus for Leap franchises for the following regions of Cyprus: Nicosia , Limassol, and Larnaca, as well as master franchise for other countries. Improve your signal strength or establish a link to your nearest access point with a long range Wireless card from Leap.
Choose from the wide range of Wireless Inrenet top-up cards. If you need WI-Fi just for a day or want to use it regularly we have the right Leap plan for you.

Which should I use? It provides for only one-way authentication - there's no mutual authentication of Wi-Fi client and the network. And very importantly it doesn't provide a means to derive dynamic, per session wired equivalent privacy WEP keys. It relies on client-side and server-side certificates to perform authentication and can be used to dynamically generate user-based and session-based WEP keys to secure subsequent communications between the WLAN client and the access point.
For a large WLAN installation, this could be a very cumbersome task. This security method provides for certificate-based, mutual authentication of the client and network through an encrypted channel or tunnel , as well as a means to derive dynamic, per-user, per-session WEP keys.
Instead of using a certificate to achieve mutual authentication. The PAC can be provisioned distributed one time to the client either manually or automatically. Manual provisioning is delivery to the client via disk or a secured network distribution method. Automatic provisioning is an in-band, over the air, distribution. The USIM card is a special smart card used with cellular networks to validate a given user with the network. It encrypts data transmissions using dynamically generated WEP keys, and supports mutual authentication.
PEAP Protected Extensible Authentication Protocol provides a method to transport securely authentication data, including legacy password-based protocols, via A review of the above discussions and table usually provides the following conclusions: MD5 isn't typically used as it only does a one-way authentication, and perhaps even more importantly doesn't support automatic distribution and rotation of WEP keys so does nothing to relieve the administrative burden of manual WEP key maintenance.
TLS, while very secure, requires client certificates to be installed on each Wi-Fi workstation. Maintenance of a PKI infrastructure requires additional administrative expertise and time in addition to that of maintaining the WLAN itself. TTLS addresses the certificate issue by tunneling TLS, and thus eliminating the need for a certificate on the client side.
Making this an often preferred option.
