Sometimes Wifi 5g shows ping 96 ms
by youni from LinuxQuestions.org on (#6GH0X)
Hello! I am using router Keenetic Giga with only one Wifi network: 5G, channel 44, static ip.
I have old PC with 2.4g only, this is why I bought USB Wifi adapter Edimax EW-7822ULC/UTC and installed driver with dkms from here This adapter supports only some 5g channels:
Code:root@devuan:~# iwlist wlxXXMACXX: freq
wlxXXMACXX: 17 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Channel 36 : 5.18 GHz
Channel 40 : 5.2 GHz
Channel 44 : 5.22 GHz
Channel 48 : 5.24 GHz
Current Frequency=5.22 GHz (Channel 44)
I run ping like this, and I found there are some slow responses:

~$Is it normal to have ping 96 ms? I touch adapter, it is not hot, but warm. May be my adapter is not so good for 5g? Speedtest shows 230 Mb/s and I think such high speed might be too much for such cheap device.
Another question
Also, is it possible to configure /etc/network/interfaces to use 2 Wifi simultaniously: 5g with interface wlxXXMACXX of usb wifi adapter Edimax and also 2.4g with my internal interface wlan0? How to type that? My current config is this (so i use only networking service, without anything else):
Code:cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto wlxXXMACXX
iface wlxXXMACXX inet static
address 192.168.1.21
netmask 255.255.255.0
gateway 192.168.1.1
wpa-ssid MyHomeWifi
wpa-scan-ssid 1
wpa-proto WPA2
wpa-key-mgmt WPA-PSK
wpa-psk pskpasspskpass

~$Is it normal to have ping 96 ms? I touch adapter, it is not hot, but warm. May be my adapter is not so good for 5g? Speedtest shows 230 Mb/s and I think such high speed might be too much for such cheap device.
Another question
Also, is it possible to configure /etc/network/interfaces to use 2 Wifi simultaniously: 5g with interface wlxXXMACXX of usb wifi adapter Edimax and also 2.4g with my internal interface wlan0? How to type that? My current config is this (so i use only networking service, without anything else):
Code:cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto wlxXXMACXX
iface wlxXXMACXX inet static
address 192.168.1.21
netmask 255.255.255.0
