First I should say I have two Netgear WNDR3700v4 routers. One of which has the current Netgear firmware and regularly gets me download speeds of 260+ and upload speeds of 21Mb.
The second WNDR3700v4 has the most current version of DD-WRT installed (build 30709) and I copied all of the settings I could find from the original router to the DD-WRT enabled router so the configuration should be pretty much the same.
The speeds on my DD-WRT router are consistently around 160 download and 21Mb upload speeds, so I'm missing obvious download speeds!
If I switch back to my original router I can get my faster speeds but when I go back to the DD-WRT router it goes back down again on all networked computers.
I assume there must be some setting(s) on the DD-WRT router that is causing the slowdown but I've not been able to find the answer through many forum searches.
My TWC connection is rated at 300Mbps speed.
When I test the old/new router, nothing is different on my network, "all things are the same".
I would appreciate any suggestions on what to try to get my DD-WRT enabled modem "up to speed"

#30709 is not the newest build but several people with your model are reporting good results at this thread :

I did update to r-30949, still, same results, still slower.

This has been answered many times. With fast internet plans you will always get better speeds with stock firmware. Dd-wrt does not have hardware NAT.
Dd-wrt is about many options.

If you are getting 160 Mbps across the WAN using dd-wrt on the wndr3700v4 that is surprising......you will never get more. 560 MHz processor won't do software nat anywhere close to your internet connection

[marklyn]

Gosh. why didn't I think of googling first?!
Of course I did. All of the search parameters I did had to do with the "slow internet" "slow download speeds" or similar searches, but I'm not sure what google search term(s) would have lead me to NAT. I checked WIKI's, looked through the documentation that I did come across.
Sorry. I'm frustrated that I didn't put the exact search engines and terms I used to try to find my answer so I wouldn't get a snide remark.

No version of dd-wrt support hardware nat. It's done by the CPU. So you would need the fastest cpu supported router which at this point is the r7800 at 1.7ghz.

Now I don't mean to say that to achieve your speed you'd need an r7800, I jus meant that's the fastest supported router.
I don't know what you need for your speed. All the routers I have can handle my 50mbps.

a dir-862L or archer c7 v2/v3 or any router with qca9558 cpu, gets about 265 mbps nat performance, without qos (u really should use qos but doing so will put even more load). thats a 720mhz cpu. the 800mhz p1014 cpu in the wdr4900 v1 (NOT v2) will get ur 300 mbps qos off.. it is a good unit too i had one.

[marklyn]

tatsuya46, that's good info. I'm researching the three routers you've stated. I see you have the dir-862L. Do you know if there is a general consensus as to which of those would be best for wireless (distance) and/or features? I'm leaning toward the 862L but it looks a little funky
Are all DIR-862L routers the same or do I need to search for a specific hw version?

Get an ea8500. Almost as good as the r7800 and in my situation it was better. I bought the r7800 twice.
You can get the ea8500 for around $120 on eBay. Range is much better than the d-link, which I also tried.

[tatsuya46]

for range and features (lots of flash space to hold all ddwrt options), none of them. for higher end they are in a different (price) league. ea8500 is the second fastest qualcomm router tied with r7500 v2 & is top of the line for range.

the 1.4ghz dual core cpu in it compared to the 560mhz wndr3700 v4 is like comparing size of jupiter to that of pluto.
