we finally figured out what was the problem with our netwrok with the new pc were placing here sa compound namin, wen i tested my pc on that 80meter cable it was fine, ung pc ng pinsan ko d2 namin kinabit sa bahay(after dalin sa pinagbilan and the ethernet works fine) it worked fine din, now wen ibalik namin bahay ng pisan ko nagkanetwork and IP pero i minute lang, we removed the LAN cable from its attatchment tapos dinala d2 sa bahay, and ayaw na gumana, we went to pcx to buy a new 60merer lan cable(P7/meter), sabi nung technician na magcrimp "Ano to infinity? Wag ito mahirap icrimp ito" then we asked what the problem was, sabi nila ung Infinity brand daw matigas ung optical wires and mahirap icrimp kaya minsan nawawala or unstable, he sugested maghanap kami the best na tatak ng LAN cable is BELDEN(P20/meter sa mall). kaya mamaya maghahanap kami sa gilmore ng Belden CAT-5
upon checking the 15meter ng pinsan kong isa na nasira at pinalitan, infinity ung kanya, ung naipalit nya was belden
