Anyone wanting to buy one of the ZYX network modems fro Libya Telecom & Technology should be aware that the modem will not work in many locations in Tripoli as they have been configured with the wrong firmware. Anyone who has a non-working modem will need to take it along to the LTT head office and have the modem re-flashed with the correct firmware.
Also be aware that the service will not work effectively with the ZYX modem unless you are in direct line-of-sight with a transmitter. Anywhere outside the city centre and your signal is likely to be very weak.
In order to receive the best signal, even in a location far from a transmitter, you'll need to connect the modem to 2 x high-gain external antennas via the connections at the back of the modem. The antennas should be mounted on a pole, at the maximum height possible and aligned to the best transmitter.
External antennas of any decent quality ARE NOT available in Libya.
