Netgear DGN2200 help needed please!

[gadgetbloke]

I have seen many people have sucessfully configured a DGN2000 to work with a sure signal. I have spent hours on the phone to Vodafone customer support. I've trawled the internet. I've opened port after port and even shut my firewall off completely (only briefly!). I still have the flashing red and two solid amber lights of doom on my overpriced doorstop that is my (latest model) sure signal. I have a netgear DGN2200 and this is my last hope of getting it to work. Please somebody out there, how can I make it work?!?

Hi gadgetbloke,

In most cases, routers support a system called Universal Plug-n-Play (UPnP), which sets up port-forwarding for you automatically. If you’ve got a complicated network setup, or a complex router, you may need to enter these settings manually.

Firstly, I’d suggest doing a full reset of your router which will return all settings to default.

Please see the following for a list of IP addresses and port numbers that need to be forwarded to your Sure Signal's internal IP address. For instructions on how to do this, we recommend you contact your ISP or Router Manufacturer, or refer to the default guide for your particular make and model, over at http://portforward.com.

Destination IP Addresses:
212.183.133.177
212.183.133.178
212.183.133.179
212.183.133.181
212.183.133.182
212.183.131.128/26

Ports and Protocols:
Port 50 - TCP/IP
Port 4500 - UDP
Port 500 - UDP
Port 123 - UDP

Port 8 - TCP/IP

Port 1723 (BT customers only) - TCP/UDP

Please note that in the above list of IP addresses, the notation "212.183.131.128/26" means the complete range of IP addresses between 212.183.131.128 and 212.183.131.191

Your router also needs to assign the Sure Signal with a DNS (Domain Name Server) address via DHCP (Dynamic Host Configuration Protocol).

BT Infinity Customers.

If you’re a BT Infinity customer, you’ll need to log into your router admin page and select port clamping.

Once this has been selected please restart your router and Sure Signal.

Check your MTU settings.

Log into your router admin page and find the location of the MTU field. This varies depending on the make and model so you’ll need to look for it.

Change the value of the MTU size to 1500.

Log out of the router, this will usually result in a reboot.

Perform a reset of the Sure Signal:

-Hold in the reset button until all lights go solid

-Pull the power lead out with the reset button still pushed in

-Continue to hold down the reset button and reconnect the power lead

-Wait for all lights to come on and then release the reset button

The Sure Signal will now try to contact the network and download its profile. This can take up to 6 hours.

Let me know how you go on.

Thanks,

Andrew
