kolizije ili hw greske?

Pozdrav svima!

Imam u mrezi uglavnom hubove, 10 mbs, starija oprema (nekih 5-7 godina), hardwerski firewall kao gateway i povremene prekide saobracaja ka internetu. U lokalu i nema nekog drugog saobracaja sem interneta pa ne znam da li i tu desavaju prekidi. Prekid se moze okloniti ako na mreznoj kartici se uradi disable/enable i poslije sve nastavi da radi kao da nije ni bilo prekida...

Nisam siguran da li zamjena hubova sa switchevima nesto pomogla ili je u pitanju neki od kablova (neispravna parica)?
Ili su u pitanju kolizije?

Ispod sam prilozio prikaz pingiranja gatewaja (hw firewall)

Pingaj svoju adresu
Zamjeni kabl

Ne mogu reci da sam shvatio: Da pingam svoju adresu sa drugog racunara ili svoju loop adresu?
Probat cu sutra i jedno i drugo i racunare medjusobno pa mozda uspijem naci koji je kabl tacno otisao...
Kablova ima malo vise, kroz kanalice i zidove i nimalo me ne raduje mijenjanje...

Nije mi jasno, kako malo radi malo ne radi?

u ovakvim slučajevima ja uvijek sumnjam na spojeve konekcije u kompletnoj liniji, pogotovo ako se često spaja i odspaja neki od elemenata u lancu.
