Netgear FVS318G cannot connect to Internet

I am using a Netgear FVS318G firewall router that connects to the Internet via a D-Link DSL-320 ethernet modem.

This replaced an FVS318v3 that was problem free for many years until it blew last month.

However, it keeps dropping the Internet which Netgear finally told me, when I managed to get through to the Ireland=based helpdesk, was down to the earlier poor quality firmware. Many people have had the same problem, however, now I can't connect to the Internet - before and after the firmware update.

I can connect using the D-Link modem only and the Netgear is picking up all the DNS connection details correctly (the correct WAN IP, Demon DNS server, but no Internet.

I can't see anything blocking it and have tried connecting it directly to two PCs.

Where am I going wrong?

When you log into the web interface does it show that the WAN connection is down or up?  What device is handling the DHCP and DNS on your network?

Have you done a full hardware reset after the firmware upgrade ?

It could also mean that the netgear is simply dying also.

I hope this helps !

Yes, done a full hardware reset several times.

Connection is shown as UP and the D-Link handles to DNS and is the DCHP server.

It may be time to replace the netgear. I would try to borrow something else to test with.

I would agree apart from the fact I can do a DNS lookup from the router???

According to Netgear they replaced many of these before realising the firmware problem.

Since it is easy enough to test with another router, I would start there since on the one you own you only have 2 options
firmware upgrade, or hard reset. If neither fixes the problem, you are SOL.

Yes, you're right. I plugged in an old spare early FVS318 and after a reset instant Internet.

I bought the faulty roter on the Internet in the UK a little over 3 months ago. Would I be better off returning it to Netgear or supplier for replacement? What is reasonable turnaround time to receive back a working unit?

You need to check the return and warranty policy of the new one, since each store is different. They may say to contact the manufacturer. You should have at least a 1 year warranty on a router ( unless refurbished )

Spoke to Netgear who feel it's the D-Link at fault as settings are as floows:

Netgear
LAN IP - 192.168.1.1
Subnet mask 255.255.255.0
DHCP Enabled
It is set to default of being a DHCP server to 2 PCs

Broadband
WAN State UP
IP - MyFixedWanIPAddress
Subnet mask 255.255.255.255
Gateway 192.168.0.1
Primary DNS 158.152.1.58 (Demon)
Secondary DNS -
It is set to default of picking up the settings from the D-Link

D-Link
IP - MyFixedWanIPAddress
Subnet mask 255.255.255.255
Gateway 192.168.0.1
Primary DNS 158.152.1.58
Secondary DNS 158.152.1.43
 LAN IP - 192.168.0.1

Netgear says it will not work as LAN IP and Gateway are on different subnets. "It's a D-Link problem."

I did get it working for a while but when I retried later No Internet???

Netgear worked fine for a while - now checking the D-Link connected alone before doing anything.

The Netgear picks up it's WAN setttings from the D-Link. The D-Link's DHCP server has a default lease time of 60 seconds (max. 65535 secs). Netgear says this is causing the problem, but it I turn off the DHCP server I cannot cannot to the Internet. This is with just the D-Link connected and I have set my computer manually as follows:

IP Address: 192.168..1.2
Subnet mask: 255.255.255.0
Def g/way: 192.168.1.1 (local address of the D-Link)
DNS Servers: 192.168.1.1 and 8.8.8.8 or 158.152.1.58

When the computer is connecting through DHCP successfully it's IP are:
IP Address: 80.x.x.x (my fixed WAN IP)
Subnet mask: 255.255.255.255
Def g/way: 192.168.1.1
DNS Servers: 158.152.1.58 and 158.152.1.43

If I could get this to connect I would reintroduce the Netgear with:

WAN IP Address: 192.168..1.2
Subnet mask: 255.255.255.0
Def g/way: 192.168.1.1
DNS Servers: 192.168.1.1 and 8.8.8.8

D-Link finally suggested to set their device to bridge mode and authenticate through the Netgear and this resolved the problem.
