Netgear Prosafe FVS-336G (fvs336g-200eus) - Slow througput

Hi centex-rj,

I have read again your initial post and since you mentioned that you have a FVS336G-200EUS, what you have is an FVS336Gv2 not an FVS336Gv3.  The LAN-to-WAN Throughput of the FVS336Gv2 is 60 Mbps while the  LAN-to-WAN Throughput of the FVS336Gv3 is 350 Mbps.  Kindly check these links below as reference:

A: Fiber (ISP Converted to RJ45 with a calistobox, and then through a cisco router)

B: It is connected to a Cisco ASA5505 as this router is used for administrative-net, and wifi. The Netgear router is being used as a guest wifi DHCP/Gateway, and is connected to the Cisco ASA. But if i connect a PC directly to the Cisco ASA there are full power (100mbit WAN)

C: Yes, WAN2 is same slow speed.

D: 4.3.3-5

 

Block TCP flood, is disabled - no increese. Also bandwith profile og content filtering are disabled as well.

 

Alsp tryed change it to "Classic routing" istead of "NAT" that gave about 1-2mbit, but

Based from you answers above, you have a scenario called "Double NAT" and this is why you are getting 25-30Mbps of LAN-to-WAN throughput through the FVS336Gv2.  Kindly try to make the FVS336Gv2 your main firewall router not the Cisco ASA5505 then observe if you will get at least 60Mbps of LAN-to-WAN throughput through the FVS336Gv2.
