 |
|
My internet became hellish slow, when my phone measure is 250Mb/s, and my computer is 2Mb/s
after rebooting my computer I couldn't connect om wifi, the service was inactive, after I connected the cable, and it is also slow.
I use Netifrc and wpa_supplicant
How can I completely delete all settings to start from zero, and recover my wifi connection? |

There is no "normal" way to cause something like that, so unless you've been looking very hard for ways to cripple your network, wiping configs won't help. (And being on netifrc with wpa_supplicant, you aleady know where their configs are)
I have both seen and heard of network devices bugging each other out; sometimes by just existing, and sometimes when certain conditions are met. One example I have right in front of me starts dropping 50% of packets after almost every single power outage forcing me to unplug its power, wait a minute, and then plug in again. I suppose initializing both ends of the link at the same time messes things up....
Do you know what is the direct cause of your network being slow? Are there any noticeable patterns?
Have you run any tests to the next hop? Checked for damaged cable etc? Are there addressing conflicts?

I realized that the cause of the problem would be an old repeater that I tuned on.
But now, after turning off the repeater, the connection is still bad.
I am using wpa_supplicant cli to connect to wifi.
I tried to configure from zero many times, the internet is working, but very slow and unstable.
The internet on another devices is fine.
I just can't understand the reasons my internet is like that. |

Hardware is always a consideration. If it's a cable, run a graphical ping on the device at the other end, too many dots, just throw a new cable over to prove it is/isn't that.
If it's wifi, move it closer to the the AP (like within 6 feet), range is the first thing to go as wifi hardware sings it's swansong.
It's also worth considering if "other devices" are using the same band as the problem device, and that your neighbours aren't stomping all over your 802.11{b,n,ac,ax} exclusively; this is why 802.11b is so stable here, no other cnut is using it within 3 miles... |

We don't know your network setup, but lets assume you are using DHCP. Providing another device which does olso provide DHCP services can lead to some mixup. So after disconnection the old repeater, a restart of your existing DHCP service (usually in your modem/router) and its clients should clean up the mess.
