Concentrator not reachable

[#1]

I'm having the same problem ( Concentrator not reachable ). I've talked to someone over the phone who insists its a router fault. I've been using my own router when I lost connection. Switching it on/off both modem and router did not solve the problem. I then switched to the Plusnet supplied router, same problem. I've talked to someone on customer services ,who made me go through all the motions step by step, insists its a router fault. And I'll be getting a new router through the post. This happened yesterday. Today I've noticed the DSL light on the modem has gone off.  
I do not believe its a router fault, and sending me a new router will not resolve the problem.
Also I like to add that initially, when I first joined Plusnet, my estimated line speed was 60mb. Now I get this:
Estimated line speed: There's no speed estimate currently held on your account.
Also my current line speed rarely goes over 50mb.
Its been 24 hours without internet, I would like to resolve the 1st issue ASAP.
Thanks

Hi 5kops,
Sorry to hear that your connection is not working, I'd firstly suggest running through our faults wizard so we can investigate your line. If the DSL light is not stable then you're not going to connect.
If your DSL light does come back on and you still get the concentrator not reachable error then it would be worth trying the following commands via telnet.
telnet 192.168.1.254
u/n admin
p/w serial number of the router found on the bottom
:ppp ifdetach intf=Internet
:ppp ifconfig intf Internet gracefulrestart enabled
:ppp ifattach intf=Internet
:saveall

Let me know how you get on.

Thanks for your reply. Went through your faults wizard and submitted all the information. The DSL light hasn't come back on. I don't suppose it will be fixed any time this week?

Did you manage to try the above?
You need to open a command prompt to do this, take a look here for some help.
Our faults team will pick your ticket up as soon as they can.

There's NO DSL light, so I can't do what you suggest. I've just been off the phone with customer service who was transferring my call to technical fault team, the call was cut off. I'm losing my patience.

Sorry about that, I'll make sure we get this picked up shortly.
