Hello,
I am having packet loss when communicating from my Ubuntu PC to the router.
From PC->router:
From other PC to Ubuntu:Code:64 bytes from 192.168.1.1: icmp_seq=42 ttl=64 time=147 ms 64 bytes from 192.168.1.1: icmp_seq=43 ttl=64 time=106 ms 64 bytes from 192.168.1.1: icmp_seq=44 ttl=64 time=108 ms 64 bytes from 192.168.1.1: icmp_seq=45 ttl=64 time=3.47 ms ^C --- 192.168.1.1 ping statistics --- 45 packets transmitted, 40 received, 11% packet loss, time 44086ms rtt min/avg/max/mdev = 0.969/12.012/147.158/31.411 ms cristi@miner2:~$
Ubuntu is running from a USB stick, has enough RAM (4GB), CPU load is ok, no high traffic usage on the interface and I don't see high read/write on the USB stick (iotop).Code:64 bytes from 192.168.1.171: icmp_seq=42 ttl=64 time=41.0 ms 64 bytes from 192.168.1.171: icmp_seq=43 ttl=64 time=121 ms ^C --- 192.168.1.171 ping statistics --- 43 packets transmitted, 40 received, 6% packet loss, time 42080ms rtt min/avg/max/mdev = 0.950/49.754/121.262/27.756 ms cristi@x1:~$
I have tried with 2 different USB wireless cards, on multiple USB port (USB 2.0 and 3x).
I have updated the system multiple times, changed the wireless channel, changed the wireless authentication method from WPA-Personal to WPa-Auto-Personal.
Other wireless devices (laptop,smartphone,ipad) had no wireless issues at all.
Using the script I found out that I had power management on and I fixed that with:
Code:sudo iwconfig wlx54e6fc921212 power offI also stopped acpid:Code:cristi@miner2:~/wireless_troubleshooting$ grep -i power wireless-info.txt1 Bit Rate=58.5 Mb/s Tx-Power=20 dBm Power Management:on cristi@miner2:~/wireless_troubleshooting$ grep -i power wireless-info.txt Bit Rate=58.5 Mb/s Tx-Power=20 dBm Power Management:off cristi@miner2:~/wireless_troubleshooting$
And:Code:sudo /etc/init.d/acpid stop
Also did router firmware update and reboot.Code:sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
What am I missing ?
Any help if more than welcome.
Thank you.
