Will It Work With My Plus.net Connection?

Yes

Why Am I Having Trouble Changing The IP Address

The first 63 addresses are reserved, presumably for use with BT WiFi open access.

Try changing the address range to x.x.x.64 through to x.x.x.253 and the router address as x.x.x.254

General

Schedule A Reboot

Create the reboot schedule:

  • Log in to the modem and open Applications >> Schedules
  • Click on an unused schedule (which are marked as x)

  1. Tick the Enable Schedule Setup box
  2. Set the Start Date and Start Time
  3. Duration Time must be set to zero, failure to do so will cause the reboot to fail
  4. Leave Action as Force On, and Idle Timeout as zero
  5. Set the How Often to you requirements
  6. Finally press the OK button.

Activate the reboot schedule:

  • Navigate to System Maintenance >> Reboot System >> Auto Reboot Time Schedule
  • Enter the number of the reboot schedule in to the box
  • Click OK to apply the schedule

DNS Problems

It could well be UDP packet defence or the DNS Cache table filling up.

UDP Flood Defence

Firstly, try disabling UDP Flood Defense to see if that cures it.

Firewall > DoS defense Setup > Enable UDP flood defense > UNTICK

Then, change the Threshold number for something bigger and relevant to your actual Download Bandwidth Rate.

Bandwidth  Threshold (packets / sec)
   20M             2000
   60M             5000
  100M             8000

DNS Cache Table

Auto Logout

Auto Logout can be temporarily altered at the top of the left hand menu to either be off or a set time. Altering the Auto Logout by this method is temporary and it will re-enable itself after you have logged out.

Auto Logout can be permanently disabled under System Management >> Management >> Top of the left hand column in the right-hand pane >> Tick: Default:Disable Auto-Logout

DNS External

To alter the external DNS servers that the unit uses (by default it uses your ISP's defaults) you will need to undertake the following:

  • Log in to the modem's web interface
  • LAN >> General Setup >> DNS Server IP Address >> Fill in your chosen primary and secondary DNS choices
  • Log in to the modem via Telnet
  • Run the following command >> srv dhcp frcdnsmanl on
  • Log out of Telnet
  • To be on the safe side reboot the modem

Thanks to Draytek.

IPv6

If you are in a backwards country that does not support IPv6 then you can disable it by the simple click of a button, which is located above the lefthand menu. Click it once you will be asked to confirm and reboot the modem.

NOTE: The picture above shows the button after IPv6 has been disable so is in monotone.

Firmware Upgrading

After downloading and extracting the firmware you will have three files, a readme and two files that match in file name but have different extensions.

  • .all which will upgrade the firmware and retain all of your current settings
  • .rst which will upgrade the firmware and reset the modem back to factory defaults

How to enable ping from WAN

Locate “System Maintenance” from the sidebar and “Management” from below that.

On this page you should see a “Management Access Control” and a checkbox titled “Disable PING from the Internet“. You want to untick the checkbox and click “OK” at the bottom of the page.

The page will refresh and that should be the router accepting ICMP ping requests! No reboot necessary! :)

Fix Network CRC Errors

Draytek 2380 Status Screen

You can change the mode of the ADSL connection. Normally it is set to 'Multimode' which will mean it determines the best mode it can achieve... or that's what it should do!

When the Multimode chose 'ADSL (995.3)', there were lots of RX CRC Errors and after a while, these build up to a point which stops the connection from working.

To fix this, change the ADSL Mode down to a lower level, such as G.DMT.

Sagemcom 2704n (AKA Hub Zero)

Expert Mode

Probably in an effort to minimise problems with providing front line tech support Plusnet have started supplying the Sagemcom 2704n modem.

On logging in to the modem's interface there does not appear to be any way to change the units IP address or manage the DHCP settings. This is of course perfectly fine for the majority of users but if you have more complicated networking needs this is not helpful.

There is however a hidden side to the modem which after logging in to it via the standard interface can be accessed by typing the following in to your browser's address bar:

192.168.1.254/expert_user.html

Within this hidden interface are the pages to change many settings you would normally expect to find.

The unit supports DSL and FTTC, however FTTC is only supported when used with British Telecom's VDSL unit.
