It has been suggested that the wireless hardware on yours may be faulty. The solution if that is the case is easy.
Otherwise your premises' topography may be such that the wireless signals from it are simply not strong enough for your environment.
There are a couple of solutions to that.
The simplest and possibly best one is to add a WAP (Wireless Access Point) connected by ethernet to the HH6, situated in whatever is the most effective location. Alternatively use HomePlugs available from several manufacturers and locate one at an better place, perhaps with a WAP fed from it.
If you have a previous modem/router that was better for you, it can often be used instead of the HH6, or it can be used as a WAP (as above) with added ethernet connections. Many of us can advise on the various setups, particularly wrt using a previous modem/router in either role, which depend on what your main problem is wrt wireless.
