I was searching for a „all-in-one“ set-up for establishing Internet connections when abroad with a motor caravan. During my Internet research I came up with a cheap and easy to handle „Wireless-Range-Extender“, that may operate also as an Access Point and UMTS-Router amongst other features, that I am not going to use.
In addition I bought a Alfa Tube(U) N , that is able to operate as a long-range USB wireless adapter, with 2.4 GHz and a power of 1000mW (that can be adjusted according to national rules).
For operating an Alfa R36 with the „Tube N“ wireless adapter, you initially need to upgrade to Firmware 220.127.116.11.
