Hey all! I have a symmetric internet connection via monkeybrains in San Francisco, and while I get ~447 Mbps symmetric via ethernet, on the same computer, if I disable ethernet, and connect to the router via 5GHz wireless only, my upload is still solid, peaking at 440Mbps, but my download never gets faster than 315Mbps.
I’ve spent the fast few days reading the wiki and the forums and I’m still in the dark. Current configuration below:
On ethernet: 447Mbps down, 447Mbps up pretty consistently whent he network’s quiet
On 5Ghz wifi: Maxes out at ~315 Mbps down, 440Mbps up
Speedtest on ethernet:
Speedtest on 5Ghz wifi
Wireless Settings:
Other misc info:
* SFE is enabled
* QoS is disabled
* I have port forwarding enabled on 8 ports, I disabled them all and re-ran the speedtest, I did not see any effect
* SPI firewall is enabled w/default settings: Arp Spoofing Protection, Block Anonymous WAN Requests, Filter Multicast, Fildter IDENT, Block WAN SNMP access.
* I enabled Local DNS for DNSMasq
* I have Static DHCP set for four hosts
* IPv6 is configured via DHCPv6 with Prefix Delegation. I’m using Radvd.
Any help at all understanding this issue is much appreciated!

Also, you can test comparing with Frame Burst disabled.
Finally, try a channel scan and set a channel, rather than use Auto. Though for VHT160, I think there's only one option, depending on your country. Some say Auto isn't reliable, but that may just be for 2.4 GHz; I've never used it for either. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

Tried switching to N/AC-Mixed, got about 7Mbps down faster than before. The N/AC run is the bottom most speedtest in the image below.
Turning Frame Burst off I don't think did much, ran two speedtests, seems right around where it was previously. Download is still significantly slower than upload, so while it's a nice and appreciated tweak it still feels like there's an underlying issue I'm missing.

At least on this firmware build in my configuration, "Auto" is the only option for VHT160
Here's the Site Survey from Status->Wireless->Site Survey
Ok, I figured this out. jwh7 got me thinking, there *is* only one option for VHT160 and so I tried to try VH80, look for an open channel, and see if that made a difference.
Here's my updated wireless configuration, with VHT80, channel 52, & lower lower (I don't understand what channel extension does at all).
And here's my WiFi running just a few Mbps shy of my ethernet
Here's my updated wireless configuration, with VHT80, channel 52, & lower lower (I don't understand what channel extension does at all).
It's for the channel bonding wireless bandwidth. VHT20 AC is the base 433 Mb/s (theoretical) on a single channel, while e.g. VHT40 is 2x (866) but bonded to a lower or upper neighboring channel. So you can see where VHT80 'lower lower', etc comes from.

FWIW, the r7000 can't utilize 160mhz channel widths (only wave-2 AC devices can).
VHT80 and lower is all that should function. I chalked it up to be a cosmetic issue on my RT-AC68u and RT-AC66u B1.
Wireless is a two-way street, so the downstream rate is prone to changing on the fly, individually from the upstream rate.
It mostly comes down to the power of the radio. Whether you are downloading/uploading to a small low-power smartphone, versus a high-powered laptop/TV with built-in wireless. _________________ LATEST DD-WRT FW IS LOCATED HERE: https://dd-wrt.com/support/other-downloads/?path=betas%2F
