I've thought cat5(e) means always RJ45 lan cable.
But my house has "cat5e 2-pair rj11 green (data) cables" from the living room to each room. My internet router is in my living room in the 1st floor (XFinity).
What I want to do is to connect the Internet line from my router through the green cat5e rj11 cable to two upstairs rooms.
My problem is how to connect from my router(RJ45) to the port RJ11 on the wall of living room and from the port RJ11 in the room to my other Internet devices (RJ45).
Is there any easy adaptor available?

The best solution you can arrange for 2-pair cables will be limited to 100 Mbits/second (or 10 times slower than the current most common standard wired ethernet speed.)
Rather than looking for an adapter (dubious at best - any you find will likely be intended for telephone signals rather than data), I'd suggest just removing the RJ-11 jacks, and replacing them with Cat5e RJ-45 jacks.
You'll connect your two pairs to the "Orange & White/orange and Green & White/green" marked terminals (1,2,3,6) and ignore the blue/brown marked terminals (4,5,7,8)Edit: Since the cables have been discovered to be normal 4 pair cables after all, connect all 4 pairs, and Gigabit (1000 Mbits/sec) speeds should be possible across them.
