Posted: Tue Aug 29, 2017 14:49 Post subject: Should I expect faster speeds?
Hi all,
I have an Archer C7 v2, a 1700AC router, running DD-WRT v3.0-r33006 std (08/03/17). I'm running N-based cards in my Mac, one floor below the router, with an 80% link strength. The router is set for "Mixed" mode, though setting to N-only has no apparent effect on speed.
My ISP net connection is 300M up and down... hardwired at the router I can see this. Via wifi I get from 20M-50M up and down. I'm testing at beta.speedtest.net, FWIW.
This seems abysmal. I know I'm not going to get the full 300M via wifi, but the N standard is about 450M, isn't it? I would think I'd get 200-250M, not 10-20% of that. Does having the A band limit me to 50M? Like I said, setting to N only doesn't seem to help.
I've looked at a couple tweaking guides and tried fooling around with RTS, and a few other settings, but I don't see any improvement. Most of my settings are defaults. I turned off all my QoS settings, too.
Does all this sound normal or should I expect better? If I should expect better, can you point me to a doc that suggests optimization changes you've found helpful, please? I'll keep looking - this doesn't seem right to me.

From what I saw on c7 reviews you won't get much more than ~90mbps on that one with 100% signal strength, so you are not far from those numbers. Check that you are using WPA2/AES, choose the least used channel among 1,6 and 11, and try with 20mhz channel width. _________________ R6400v2 (boardID:30) - Kong 36480 running since 03/09/18 - (AP - DNSMasq - AdBlocking - QoS) R7800 - BS 31924 running since 05/26/17 - (AP - OpenVPN Client - DNSMasq - AdBlocking - QoS) R7000 - BS 30771 running since 12/16/16 - (AP - NAS - FTP - SMB - OpenVPN Server - Transmission - DDNS - DNSMasq - AdBlocking - QoS) R6250 - BS 29193 running since 03/20/16 - (AP - NAS - FTP - SMB - DNSMasq - AdBlocking)

u need a r7800.. whatever talon ad 7200 is ull end up back here wondering why ddwrt dont work on it, i know that much about it, cause its unsupported.. & ad is garbage that jacks up the price for range that is equal to the width of an uncooked spaghetti noodle. _________________ LATEST FIRMWARE(S)

well.....,Archer C7 has a very slow CPU so max WAN speed is very hypothetical...
with stock drives you have Hardware Nat Support...so it does well...
to enable that in DD-WRT log in to GUI Setup>Basic set up>Optional Settings>SFE enable...
SFE is still in development so do not expect miracles...
anyway if you 'd need a heavy duty router save the hassle and get one R7800....
p.s. those advertised Wi-Fi speeds are only LAN to LAN most of those single core CPU routers are not designed for a modern internet speeds WAN 200Mbit+ _________________ Atheros

SFE or Shortcut Forwarding Engine is an option on the Setup - Basic Setup page of almost all routers now running a build after 33006 I believe.
Please note, it may still break QoS at this point, it is very much a work in progress. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.

Wow! Thank you, gentlemen, Alozaros and Ian, I found it like Shortcut Forwarding Engine. It is ON in my configuration by default. I'll test it.
The only reason I think SFE *could* work is because it will off-load the CPU from WAN traffic and will focus on WLAN traffic. If that doesn't happen then it's useless. _________________ R6400v2 (boardID:30) - Kong 36480 running since 03/09/18 - (AP - DNSMasq - AdBlocking - QoS) R7800 - BS 31924 running since 05/26/17 - (AP - OpenVPN Client - DNSMasq - AdBlocking - QoS) R7000 - BS 30771 running since 12/16/16 - (AP - NAS - FTP - SMB - OpenVPN Server - Transmission - DDNS - DNSMasq - AdBlocking - QoS) R6250 - BS 29193 running since 03/20/16 - (AP - NAS - FTP - SMB - DNSMasq - AdBlocking)
My Internet speeds are 100/2 Mbits. For speeds like my, the router works well, but if SFE may impact to QoS it is not good news. I had running some test and not got any clear result about both of variants.

The "n" routers may do 36 megabits in the presence of interference, even if your laptop is nearly atop the router. Although it may seem counter-intuitive to select the 20/narrow-channels on purpose, that gives you the opportunity to go up to 150 megabits (on a 300n) if you can find a reasonably clear channel. So, be sure to use the wifi survey feature.
There's also this command:
nvram set et_dispatch_mode=1
