2,4GHZ is ok with Speed. 5GHZ Speed is very slow only max 100Mbits from 200Mbits.

[egc]

Try Us domain, try other channel e.g. 108, I easily get > 200 Mb/s on my R6400

Of course WPA2 /AES for security.

The range of 5 GHz is limited so you can only get good speeds with 5 GHz if you are adjacent to your router.

This is actually my config and it is the same. When i make Speedtest first 180,170,160.....90Mbits test result and not constant 200-202Mbits Speed.

[egc]

Do not use auto channel
Do not use optimize multicast
Do not use spaces or comma's in your SSID
Do not use mixed other then AC/N mixed for 5 GHz

It is the same result by me. The Download speed is too slow. Over 100Mbits Download speed not using.

I have no idea why this is so. I have exact the same config changed but no effect.

With LAN Cable on Notebook i have fullspeed with 205Mbits.
With Laptop AC Wlan, Smartphone Note 4, S7 Edge, S8 with AC 5GHZ Connection Downloadspeed under max 100 Mbits.

[Per Yngve Berg]

What is the download speed from a wired client?

[humiboy]

With Lan Cable on Laptop without Wlan 200-205Mbits Fullspeed.

With Wlan only 40-100Mbits with 5GHZ AC Connection.

[humiboy]

or have the newest Build from Kong a Bug with Wifi Speed?

That is the first flash from DDWRT on my R6400. Over 6 month no problem with AC Wlan Speed on Netgear Stock Firmware. Always 200Mbits Fullspeed constant.


Only with DDWRT i have problem with Downloadspeed. But what is the problem by my config.

And why by Sys Info the Rate is always different?

AC Wlan > 780 Mbps, 866,5 Mbps, 400 Mbps, 702 Mbps......
2,4 Wlan > 65 Mbps, 104 Mbps, 78 Mbps, 130 Mbps....

[humiboy]

It is so frustrated why i can not use fullspeed on WLAN Connecting.

You came from stock so I advise you to do an erase nvram again.
Telnet into your router and do:

[humiboy]

I have erase nvram after Flash ddwrt from Stock Firmware.

Again erase nvram or waiting for Next Build?

[dance85]

In my opinion, we are waiting for the new build. I have the same problem with my new R8500 and the WRT1900ACSV2. They are snails. They have all 2 problems on the wifi. During streaming buffering, buffering, buffering ... it's been a long time since another build is released. We are running out in my opinion ....

[humiboy]

I have updated to latest Kong Build with ddup flash latest and after erase nvram.

I have put my settings manuell and the result is the same.

With 2,4GHz Max 104mbits + -
With 5Ghz 60-100 Mbits + -

[egc]

I am using the latest Kong build 34015, and speedtesting from WLAN <> LAN, 5 GHz on an old laptop, which can only do VHT40 single stream, gets me 230Mb/s, connection status show as VHT40 300Mb so that is exactly as expected I think.

Android phone show connected VHT80 866Mb/s However I can not test from this Android phone (I can run speedtest but my internet is just 40/4)

You are sure you have a R6400 v1 and not a v2?

[humiboy]

yes i have Netgear R6400 V1 not V2

With my HP Probook with Intel(R) Dual Band Wireless-AC 7265 i have

with 2,4 GHZ good Downloadspeed 188Mbits+
download 18-20 MB/s
with 5 GHZ i have max Downloadspeed 60-120 Mbits
download 2,4-4,4 MB/s

With Smartphone LG G4, LG G5 with 5GHZ i have Downloadspeed from 180-202Mbits

With LG Smartphones Connection is OK with 5GHZ

With all "Samsung" Smartphones, Samsung Galaxy Note 4, Samsung S8, Samsung S7.....with 5 and 2,4 GHZ the Speed is very very very slow

with 2,4 GHZ max 100 Mbits + -
with 5GHZ 60- 100 Mbits + -

Is here a problem with all Samsung Phones with Wlan Chip and DDWRT?
