Dear all,
I would like to use this alternative firmware but I have performance problem in 5GHZ wifi, I explain:
with the original Netgear firmware I have a maximum transfer speed of 1733Mbs in wifi in 5GHZ, I have a 1GB fiber connection and I arrive at 922Mbs downloading in wifi.
With the firmware ddwrt, last released, I tried to set any setting but I never get to this speed, if I remember correctly the maximum was 500-600Mbps at most.
Rollback with original Netgear full speed firmware.
Someone with the same problem as me who can help me set options?
I've already tried the recommended ones but nothing...
below optimal circumstances I reach with dd-wrt 850-950Mbit on the R7800
but is a pure measurement between the client and the router (iperf3 runs on the router cpu)
is therefore a relatively senseless measurement because it is not realistic
when I do a WLAN <-> LAN measurement I have never reached 1Gbit
there is with my setup at ~800Mbit the end of the flagpole reached (stable 750mbit)
with 95% CPU load
i think that's all the r7800 will do without proprietary NAT ,network accelerators, WLAN chip offload
in addition, it achieves the link rate of 1733Mbit only at short distance and max 1 wall
is the distance a bit longer and several walls in the game you can reach a maximum of 1000Mbit link rate (and with this link rate you can't reach a gigabit throughput)
let me know when you have found the solution to the problem, I've been trying to squeeze more out of the r7800 for ages
hi,
yes, i'm surprise about same speed from lan cable and wifi with this "Old" router, so, my client is Dell Latitude 5310 with Intel Wi-Fi 6 AX201 2x2 802.11ax da 160 MHz + Bluetooth 5.1
With my old laptop, dell 5280 max wifi speed was 680Mbps, with this 922Mbps from speed test ookla with original netgear firmware. With ddwrt, 500-600 max
Damn

If you turn on shortcut forward engine on the main setup tab you should be able to get more speed, albeit without any qos.... if it's speed you want you'll have to go without qos. _________________ FORUM RULES

Damn
that brought another ~150Mbit .....
why is default set so low?
Does the high value now have disadvantages?
all direct WLAN <--> LAN throughput
it looks like retransmissions have dropped significantly
good finding. caused by old broadcom related crap code. i applied a fix for the wrong rx queue size _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s
