Replacing old home telephone wire?

You said you used a 30 foot phone cable from the wall to your modem. Assuming there isn't anything wrong with that cable can you connect the modem to another jack and then a longer Ethernet cable to connect from the modem to your competer? That way you don't have to move the computer. Or use a laptop to do the test if one is available to you.

Do I check the other phone jacks to see if I'm getting any signal on my modem?  Or am I checking for speed?  If the latter, it means dismantling everything and moving my entire PC setup over to the jack. That's going to be a huge PITA.

I will post more photos soon.

Phil_Harmonic  Your best bet is get some one that knows tel wiring that is a mess. The tel wire from the 80s is still used today. I see 2 tell wires stapled with a 90 degree bend in it could be the problem. Only one  tel wire will go to the demarcation box should be nothing wrong with it. Also one loose tel wire going somewhere? There are 4 wires in tel cable you only need 2 but you can bond them together to have more copper wire to feed outlet.

Phil_Harmonic  Xray gave you list of things to do. You could look at the connections in your outlet box ------ make sure they are not corroded  clean them up. Phone lines are sometimes daisy changed bad setup not single  runs to demarcation point. Check all outlets and try a different outlet and check your up down speeds on all of them. Still no change get electrician and cut the rock. You should be able to open up the tel cable close to the demarcation point and hook  up your new tell wires. . If get your speed up with the new wires you could leave it at that or call tel and have tech install new wires at the point of entry. Possible charges

In the second picture there a spot in between the two breaker panels with a punch panel and junction box. Can you post a close up of that?

Telus owns the NIB/Demarc box so electricians likely won't touch it. Do you have just the NIB/Demarc outside the house or is there a box inside as well?

Nearly all houses have a line coming in and there will be somewhere inside the house where that line is split to the other jacks. Some houses are wired in daisy chain style where the line runs from one jack to the next. Others can have independent runs to each of the jacks. Some are a mix of the two.

Do you know for certain that the wire from the NIB/Demarc outside runs directly to that specific jack?

What is the Obihai ATA device connected to?

If no splitter was installed, definitely try moving the modem to another phone jack to see what happens.

1. Already answered. No other devices (apart from the ATA) connected to the PC or to the phone line. No fax machine, no caller ID box, no other phones, no alarm system, no splitters (that I'm aware of). My upstairs neighbor doesn't use a landline phone and has no computer.

2. There is no phone jack in the laundry room. There is one in the bedroom (beside the laundry room) and one in the kitchen. Haven't tried to connect the modem to either of these jacks.

3. Laundry/boiler room showing where all the lines come in:

Ok, but if you can't change or alter the wiring inside the house without disconnecting the wire at the NIB box (which is locked, and I presume only Telus is permitted to unlock it?), then do I call both Telus and an electrician?

Correct me if I'm wrong but I didn't read anywhere in this thread answers to the following questions:

1. What else is connected to the phone lines in your house? Nighhawk asked several times but I don't see an answer. Not the network, the phone lines. Answering machines, alarm systems, caller ID boxes, fax machines, phone extention cables, splitters, etc. I would unplug everything and do a test.
2. Did you do any tests by moving your modem to locations to see if the suspected wiring problem can be isolated?
   1. Is there a phone jack in the laudry room? That's the first place I'd try.
   2. Phone jacks in other rooms if there isn't one in the laundry room
3. What does the telephone wiring look like in the laudry room?
   1. Do you see a junction box on the wall where the phone lines are split out?
   2. Do you see any filters or splitters?
   3. Post a picture if you don't understand the wiring.

Phil_Harmonic  Wiring Inside a house or suite belongs to the owner. Long time ago the telephone company would wire a house for a price.when hard wired phones went by the wayside they quit trouble shooting the wiring. For a while they did at a about a $100 an hour. If you are renting it is the landlords  call to fix the cable.
