I recently installed a FVS318g with comcast being the ISP. My connection should be 75 down 25 up however I am only getting 15 up/down thru the netgear firewall. According to the documentation the FVS318g Lan to Wan is 250mbps any ideas?

the specs clearly state 250 http://www.netgear.com/business/products/security/FVS318G.aspx#tab-techspecs

Remove the FVS318, connect a computer directly to the Comcast modem and re run the speed test - what results do you get without it?

when connected directly without the firewall connected I get 82 down and 24 up

Try disabling any 'block udp flood' or 'block tcp flood' settings. We've found this to speed up our various fvs units and solve some problems as well.

I am running a similar issue only with an FVS318G-100NAS.I get 25-27M download and 4 upload on my cable modem but when I use the FVS318G with nothing else connected except a laptop and the cable modem I see anywhere from 3-4M. I would expect to be seeing closer to 15-20M I would think. This issue has begun only recently. I have checked and used various cable but am still seeing this slow WAN throughput

There could be a number of weird things going on. Ive seen strange things happen to routers even when just the back end of the isp was changed.

To fully diagnose the issue, it will be necesary to connect the router to another router or internet source to see if it acts strange there too.

Of course this can only confirm an issue with just the router or if there is something about the partuclar modem/router setup.

  So is it a hardware issue? I don't have two ISPs just one. Not sure how I can test with two ISPs

    To determine if it's a hardware issue, you'll need to connect it to a switch in between the fvs and your modem. If it's dropping connection to the switch (a dumb unmanaged switch), then more than likely the fvs has a hardware issue or a auto speed/duplex problem, the latter of which could be worked around by manually setting the speed/duplex.
