New installed OpenWrt 18.06.2 on Buffalo WZR-HP-G300NH (Hardware supports 1000Mbps both on WAN & LAN, and 300Mbps Wi-Fi)
1)LAN SPEED:About 330Mbps download speed on ASUS RT-AC66U B1 from Internet, but no more than 200Mbps download speed on WZR-HP-G300NH
2)WLAN SPEED:About 330Mbps download speed on ASUS RT-AC66U B1 from Internet, but no more than 100Mbps download speed on WZR-HP-G300NH
(Mode N, Channel 6, Width 40MHz, Transmit Power auto, Encryption WPA2-PSK, Cipher AES in LuCI)
UPLOAD SPEED is about 30Mbps, same on each router, no matter LAN of WLAN
All tests are based on 'Speedtest.net by Ookla', same remote server & same settings, Wireless speed is tested on iPhone 7 Plus
Problem of OpenWrt or WZR-HP-G300NH? How to improve?
The device looks like it has a 400MHz cpu so it most likely reaches the limit of throughput rate. You can verify that by running a
top command while performing the speedtest. Check the cpu utilization on the second line and pay attention to the
idle % value.
as flow offload is not yet available for your device (daily snpashots for now http://downloads.openwrt.org/snapshots/targets/ath79/generic/) your only chance to get higher speed with openwrt is to compile your own image with qualcomm's SFE module https://github.com/gwlim/Fast-Path-LEDE-OpenWRT
Tested, about 15% idle while download speed is above 200Mbps+(WZR-HP-G300NH's WAN to AC66U B1's LAN, no PPPoE)
Well, that's how it is... You can do some tweaks which might increase performance slightly but ~140-150Mbit is pretty much the limit for the AR9132 CPU and that's excluding PPPoE.
with SFE patch it can do >400 mbps via pppoe and ~700mbps ipoe (simple nat)
if you can't/don't want to patch it you can try dd-wrt that has SFE included
There's only 'Migrate from DD-WRT to OpenWrt', no 'Migrate from OpenWrt to DD-WRT'
Instructions on "how to migrate from X to dd-wrt" would logically belong at the dd-wrt sites.
General advice is to flash back to stock manufacturer's firmware then follow dd-wrt instructions to install from stock.
Many THX, and why offical OpenWrt does not include SFE/SIMPLE NAT while DD-WRT does on this device?
SFE wasn't accepted by the openwrt developers.
they implemented a different technology - flow offload - available only for ath79 targets.
your router wasn't included yet in this ath79
The flow-offloading infrastructure has been merged into the mainline kernel (not just OpenWrt) with kernel 4.16 (and was backported to OpenWrt's 4.14 kernel), it's available to all architectures with a current enough kernel. Maintenance for this new feature is covered by the mainline netdev developers and doesn't require the OpenWrt developers to maintain it (while SFE is an out-of-tree implementation, which would have needed constant attention by OpenWrt developers). Furthermore the flow-offloading feature provides a unified interface for software based offloading and hardware acceleration (currently only for mt7621, but AR8327N/ QCA8337N and lantiq (potentially even the ipq806x NPU/ NSS cores) would be other potential candidates).
That means flow-offloading will never appear on ar71xx, or just keep waiting for future editions(including snapshot builds)?
I understood all models in ar71xx will be migrated to ath79.
The developers just need time and a real device to do the porting.
Netfilter Flow Offloading (in ar71xx):
||v19.03 (next release)
THX, so when will v19.03 stable release be ready for users, Mar 2019?
