Ethernet refuses to connect, but works on Windows(just mine)

[Joe Jackman]

Few days ago one of my ports died, and the next day after i checked it up by my ISP (they usually don't ask to bring the router to them) and after a lot of tinkering somehow it worked (he was shocked as he basically gave up on it and 5 min later it started to work again) . Later when i log into Linux_ it does not connect. If i just change the port (on the router), it connects with no issue. Also i have 2 other computer that CANNOT connect to that port.

Are the ports somehow different (on the S/W side of the router)?

 

If I understand your description correctly, it looks like a failing port (i.e. doesn't work, works after fiddling, doesn't work at home while other ports work ... etc; i.e. works - doesn't work - works - doesn't work ... )

they are physically the same and ya idk. let me rephrase- it only works on my PC (windows), other PCs have windows too but they dont work (cant detect ethernet cable) as well as my Linux(dual boot).

What I meant, are the port  separately configurable on the router, and if they are, have you changed any settings?

 

If not -> it is most certainly a H/W failure on the router.

um they are not, its static IP and DNS is fixed and i checked port trigg/forwarding but nothing there. but how is it a hardware failure if i am replying this using that port.

UPDATE
Fixed.....
Just needed to change from full to half duplex, even my ISP have no clue but my connection shows its true package speed when i run at Half duplex now as the port itself is damaged (kinda) i believe it cannot push that many lanes(for full duplex) but windows somehow is able to carry it regardless (i made some changes in the adapter settings to give me stable ping). HOW THE FK I DIDN'T THINK OF THIS BEFORE.
