The existing setup is Belkin N600 DB wireless N+ router (Model F9K1102v1) in the loft connected via CAT5 cable connection to the BT Hub 3 in the office which has a relative high download speed of between 12Mbps and 15Mbps (ADSL). The distance between the Belkin N600 and the computer that needs to receive the wireless signal is approximately 30m max. At present the signal is minimum too slow and useless, it cannot be used to download anything!
Unfortunately there is no duct between the two buildings and running a CAT5 or 6 cable is impossible because of the difference in height and the narrow road between the two buildings (see picture link attached).
I would appreciate if anyone knows of a better route/access point that can be used to improve the wireless signal between this two buildings.
