fvs336G v3 - slow throughput

Hi there,

I have the same issue. I have a PROSAFE FVS336S V3 (firmware 4.3.5-3) and I have performed several test on it in order to understand why it cuts 30 Mbs to my internet speed.

My scenario:

1) I have a VDSL2 internet connection (200 Mbs download and 20 Mbs upload...at least theorethically )

2) I have a VDSL2 Modem set in full bridge (authentication with ISP is thus perfromed by the Netgear Firewall)

3) I have tried to test the internet speed (by using several internet speed test available on the web, either flash based and non flash based and thus by getting the average values) by going in to the Modem directly with my PC and by getting connected by setting a wide-band connection on my PC. Test result: 75 Down / 20 Up)

4) I have tried the above said again, by putting in the middle the Netgear Prosafe and the speed was cut 40 Mb off in Download ! (no changes on Upload speed).

5) About the Prosafe settings:

    a) I have to VLAN, both getting the Internet from the WAN1 port - To perfrom the above said test, I have disabled the VLAN #2 and I have attached my PC in to the VLAN # 1 port.

    b) I have three VPN connetions set (two IPSEC on demand and on Peer to Peer always on) - To perform the above test I disabled all the VPN connections

    c) I have severl WAN to LAN inbound and outbound rules set - To perform the above said test I have disabled ALL THE RULES

    d) I have an IP/MAC protocl binding chart set in to the Firewall (about 30 MAC bound with IPs) - As said above, I have performed the above said test by connecting my PC straight in to the VLAN #1 port of the Firewall, so I do not think the IP/MAC binding service can affect the speed test (no other PC are connected to the LAN, but my one)

    e) I do not have any other service set as ON in to the Firewall: no QoS, no Traffic Meter/Control, no DMZ, no Logs, nothing else but the above said.

So, the question is: Why the Firewall cuts the internet speed ? Why it cuts 40 Mbs off even if it doesn't have any service to work on ? The WAN-to-LAN speed of the model I bought should be 350 Mbs so, I guess there is enough room to perform a 70 to 75 Mbs speed on WAN, don't you think ?

Please help me with this really annoying issue.

Thanks

Jacopo
