Plusnet Fibre - BT Wholesale Error

[#1]

Hi Everyone,
I have recently bought plusnet fibre (actually its been 2 days) but I can't use internet. Every time I try to open a websites, BT Wholsesale page (Green page of death) comes up. I have searched this forum and found that it is problem with my DNS. To change DNS I have to telnet the router. I have tried telnet to the router (wirelessly and with lan cable) but every time it gives me an error that "..Could not open the connection on port 23...". This is really annoying. I have tried to contact plusnet, they say its not a problem with DNS and that they need 3 days to sort your problem. Life is too short to wait 3 days..
Could anyone plz temme how to change DNS settings when I am unable to telnet the router. I have checked to change the user.ini configuration file and have found following information related to Telent, any clue what needs to be done? Is there easy way to change DNS?
[ expr.ini ]
add name=telnet type=serv proto=tcp dstport=telnet
.
.
[ labelrule.ini ]
rule add chain=qos_default_labels index=16 serv=telnet log=disabled state=enabled label=Interactive
.
.
[ service.ini ]
add name="Telnet Server" mode=server
.
.
rule add name="Telnet Server" protocol=tcp portrange=23-23
.
.
[ servmgr.ini ]
ifadd name=TELNET group=lan
.
modify name=TELNET state=enabled natpmweight=10
.
mapadd name=TELNET port=telnet

It won't be anything you need to change in the router - it indicates that you are not connectling correctly to Plusnet but instead to a BT Wholesale system. When you correct correctly your router will be allocated the correct DNS servers.

Thank you Jelv.
Any idea how this is going to be fixed? If this is something Plusnet has to configure at their then it should be fixed in few hours, no? 
Last I talked with Plusnet they said they would need 3 days time to check the line first and then would come back to me to see if box needs replacement.

Could you post the output from the following please
tracert 212.159.6.9

212.159.6.9:
1 *  *  Request timed out

30.....
Google.com
Tracing route to www.google.com [62.6.38.125]
(same as above)
Just to mention BT Wholesale IP (Current DNS in my Technicolor box) is 62.6.38.125

have you tried turning the router off leave it for 30 mins or so and then turn back on.  This might solve the problem.
This solved my issue as I've that page before many times

Thanks Jamie.
I have tried on and off several times but no luck. I think the box is crooked or the line is. I was under impression that by changing DNS, the problem should resolve but its not so easy to change DNS.
Argument from Jelv is also right that DNS should be set right if the link is working fine. Anyway, after 3 days plusnet is going to send engineer home to check this. If I dont get it fixed by Saturday I think I will change my provider. Work from home is not possible if internet is not working.

Shouldn't the first hop of the trace-route be the router(gateway) even if the connection itself was down?

This is looking a bit more fundamental. Could you post the output from the following two commands please:
ipconfig /all
ping 192.168.1.254
