7 wires out of 8, should the network work?

Good day! Faced such a problem:
At one fine moment, the Internet fell off on the computer with an error network cable is not connected.
I rang the cable and found out that wire 3 (green-white) was open.
Is it normal that if one wire breaks, the network cable is not connected error?
What pairs can be transferred to the place of green with less harm to the network?
Network 100 megabits

If 1, 2, 3, or 6 is off, it won't work at all. 1 and 2 are one pair, 3 and 6 are the second pair. If any of these wires break, there will be no link.
Decide how - re-compress both ends and check. If the same - it means a break somewhere in the cable. Then you can either find the place of the break and put a "barrel" there or shift the cable ... Well, or take a brown or blue pair instead of green (respectively, 1GBit / s will not work, only 100MBit / s).
