Here my snr margin this few days is around 18 or 19 and lower...Therefore, i face frequent dc while gaming. Like what most of us will do is call up tm and bang them upside down until they sent a technician over. When her arrive, the 1st place he go is the interchange point which connect my inhouse copper line and the outside pole copper line. Once he open the casing it full of lizard egg shell and a dead lizard. pity him, he have to clean it up for me..

he then check the copper line copper line colour, it black ( a bad sign, since black indicate the copper is already heavily oxidized), a quick google search will tell you that copper oxide is not a conductor while a proper telefon line should be only pure copper and orange in colour. So he ask me for a cotton bud, a thine piece of cloth and s small plastic container.. Then he pour a small amount of acid, that he bring with him and started using the cotton bud to clean the black copper wire, until the copper wire turn to orange again, it like acid bath, rinse it with smal amout of water and connect both wire again and used a duct tape to insulate the wire

a second check show that my snr margin jump to 32, almost half or 50% improvement..

he then told me it just a temporary solution, i have to call TM again to ask fully replace my copper line from the pole to my house. and the acid wash only a small portion not the entire wire

hope it help felow LYN on quick and easy way to improve your snr margin although just temporary, i happy with the work done
