Hi
I bought netgear R6220 recently.
I'm trying te get as much wlan speed as possible. On 2,4Ghz I'm getting only ~53Mb/s an on 5Ghz max 105Mb (LAN <> WLAN). No matter what settings I'm using speeds are very poor. Also I'm not able to set 40Mhz on 2,4Ghz. I'm not in a crowded area, almost no WiFi networks around me.
Can anoyne test their R6220 and show results, it would help a lot.
Oh, it doesn't matter if I use 18.06.2 or master branch.
~53Mb/s an on 5Ghz max 105Mb
Sounds like a jobs for ethtool.... have you verified / eliminated the physical links in the chain?
Test with a few clients.... and few "chokepoints" in the mix.......
Post your etc/config/.... wireless? too....
Ok. My phone LG G6 and my laptop was tested on original firmware.
Original firmware:
WLAN <> LAN = 79 Mb/s on 2,4Ghz - laptop and phone LG G6
WLAN <> LAN = 335 Mb/s on 5Ghz - laptop and phone LG G6
Openwrt:
WLAN <> LAN = 53 Mb/s on 2,4Ghz - laptop and phone LG G6
WLAN <> LAN = 105 Mb/s on 5Ghz - laptop and phone LG G6
So my PC hardware is not a bottleneck.
My /etc/config/wireless
root@OpenWrt:~# cat /etc/config/wireless
config wifi-device 'radio0'
option type 'mac80211'
option hwmode '11g'
option path 'pci0000:00/0000:00:01.0/0000:02:00.0'
option country '00'
option legacy_rates '1'
option htmode 'HT40'
option channel '6'
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'Openwrt_2G'
option encryption 'psk2'
option key '...........'
config wifi-device 'radio1'
option type 'mac80211'
option channel '36'
option hwmode '11a'
option path 'pci0000:00/0000:00:00.0/0000:01:00.0'
option htmode 'VHT80'
option country '00'
option legacy_rates '1'
config wifi-iface 'default_radio1'
option device 'radio1'
option network 'lan'
option mode 'ap'
option ssid 'Openwrt'
option encryption 'psk2'
option key '..........'
2.4Ghz-53Mb/s: option hwmode '11g' , why not '11n'?
The Netgear R6220 has three different models under the same name. Make sure you have the same WAN MAC address on OpenWrt as the one printed on the back of the router.
If the MAC addresses doesn't match. You need to find the correct firmware. Using a wrong/incompatible firmware results in unstable 2.4 GHz wireless and poor performance in 5 GHz wireless for this model.
I'm aware of MAC address issue. My MAC is the right one, the same as on label on the router. That is not the problem.
The radio behaves weird, client is connected but after couple of minutes there is no communications to the router through 2,4Ghz, I have to reconnect in order to regain internet connection. Dmesg shows nothing, logread shows nothing. This is a driver issue. And the speeds are as I shown on the second post.
Install iperf3 on the router and a wireless device. Check the bandwidth and post the results here.
Can anyone post his results first so I can compare them ? I'm selling this router because of this WLAN issues, but I want to do everything to find out what the problem is before giving it to another person.
5 Ghz Wireless. -62 dBm 780.0 Mbit/s, 80MHz, VHT-MCS 8, VHT-NSS 2, Short GI.

iperf Done.
Sorry, my 2.4Ghz is currently in wireless mesh mode. The tests won't show the actual bandwidth.
What about 2,4Ghz ? Ok, thans I see now. I will do my tests tomorrow.
So any update? Is netgear r6220 good enough to buy in terms of speed/performance? Or is there anything better (for same price range) ?
