@Phil_Harmonic You must be in alberta Jack rabbit. It is a mess ---outside box 3-4 tel wires out along wall and in telus did not do this. The box cover is not on correctly crooked the screw on the right side is not normal unscrew it and see the mess in there. The pipe from that box also has tel wires in it so somewhere in the house is a set of terminal blocks to seperate out the two suites. A previous person has strung wires to where they wanted a phone and drilled through the wall not right. See if you can see where the pipe wires go to. Who ever finished the basement covered them up. The terminal blocks should be close by the electrical panels. There must be another panel somewhere for the second meter. Another basement? IS THIS A DUPLEX. I love to help people retired power lineman. Private message me with your phone number and i will try to help you. And best time to phone you Open box first and have look.
"So I wonder if the dining room jack itself is faulty, or if it's the line behind it. Does this also mean there is a splitter somewhere that divides the kitchen jack from the dining room jack?"
Seems like you have narrowed it down to the Jack, or the wiring to it. Next step becomes to try and see if you can trace the dining room jack wiring back to where it connects with the rest of the wiring. The issue could be damage to one of the wires in the bundle, and simply switching to a different pair at both the jack end and where it connects to the rest of the wiring might be the fix.
I agree with @polecat that the existing wiring is a mess, and who ever installed it takes no pride in their work.

Agreed, the wiring is a mess and it needs a professional to sort it out. In the meantime I recommend running a good quality phone extension ffrom your modem to the Modem jack in the laundry room and forgo using any of the wall jacks.
@Phil_Harmonic I will narrow it down again. Terminal between panels. To me looks like white goes to green ------blue to red------it is like a little switch open the empty one and hook wire to bedroom to it w to g -------b to r Just follow colors the way they are hooked up Could be white to red etccccc IN THE BEDROOM OPEN IT UP AND SEE WHAT COLORS ARE HOOKED TO THE RED AND THE GREEN USE THOSE COLORS TO MATCH BOTH ENDS OF THE WIRE IF the outlet does not work then the living room and kitchen are fed a different way. blue and the white should be used on both ends.
@Phil_Harmonic @xray I didn't see that but i found it . Ok line in white and blue the other line Whitch says modem is hooked up white and blue-------that wire could be living room wire where the modem is or the kitchen outlet. that tests good. There is a bunch of wires that are hidden in a wall ???? I think the line in is the one that comes in by dryer vent. Not from conduit.
@NFtoBC This is a duplex so somewhere there is an area where the wires in the box are sent to respective units.???? The box has being pried open to break a hole on the side for wires. So inside is a terminal block???? and what about the wires in the conduit where do they go???? do they do living room or kitchen???? Wire on the outside wall is not correct What mess and puzzle
@NFtoBC @Phil_Harmonic The utility box should be tel only possible two tel wires down --connector block inside --with wires continuing down conduit and into house. Three other cables from hole in box through holes in wall. Several coax tied to conduit onto the ground ??? The box has been pried open now held shut with a screw on right side. The cable going in by dryer vent i think goes to little block inside. Whats in conduit i hidden inside a wall or something. possible block wire feeds living room or kitchen. Or kitchen from hidden block? Picture of top of tel entrance needed and open box screw out lid should fall off.
So I tested the little box marked 'phone', 'line' and 'modem' and it works. However, connecting my modem to it would not be feasible since I'd have to run long ethernet cables through the laundry/boiler room doorway, and down a hallway and into the living room where my desk and PC are.
I talked with my ISP again, and told them I had narrowed down the problem to an issue with the telephone line behind this wall jack (some kind of combination of coax cable and phone cable jack) in the dining room:
The ISP said they could send out a tech to fix it, but it would cost $125./hr. I don't think the tech would be able to replace the telephone line anyway, as I previously mentioned, if the line is stapled to a stud, they wouldn't be able to pull it out without ripping out the dry wall.
This is the wall jack in the kitchen:
I managed to run the CAT5e cable from the kitchen wall outlet all the way around the living room to my desk (on the left) where my modem and PC are. But as you can see it means running it above the radiator. I think it will be okay though.
Since I am getting 44-45 Mbps (not ideal, but good enough), I've decided to live with it this way.
Thanks to everyone on this thread who helped me with this problem! I may not have bothered to try and test the kitchen wall jack otherwise.
@Phil_Harmonic Glad to see you found a work around that will work for you. That wall just has cable and telephone in same box (saves money on boxes and plates when building) they are seperate functions and not joined together. The actual tel jack could be in trouble =loose =broken= rusty= you could check it and replace it with a new jack and cover plate (push cable back into wall and leave it. Polecat
