Replacement hub installed, lost static IP address

[zzZZzz]

We have 1 static IP address assigned to our BT business broadband service.

This morning, the existing 2700HGV mysteriously developed a connection fault  (broadband LED flashing, no ADSL line speeds reported on hub home page)

Rebooting it a few times made no difference, so we unboxed a spare sealed/unused 2700HGV (with older v6.1.1.48 firmware) and plugged it in. The broadband/internet service is now restored.  

Unfortunately, we seem to have lost the static IP address assigned to our broadband connection.

We tested momentarily unplugging the ADSL cable, but upon reconnection, we got yet another different dynamically assigned public IP address. 

Update: I think it may be a username issue.  The new hub uses default username 'green-light' and has failed to automatically populate itself with the correct BT username and password.

Hi zzZZzz

You are completely correct.

If you have a single static IP address firing in the correct Chap Username and Password will get you your static IP back

This would be on 2 separate letters sent to you when you first took out BT broadband.  If you no longer have these feel free to contact us and we will get this for you.

Hope this helps
