#Windows 10 / linux mint 20.1 dual boot network not reachable on linux but works on windows

Some background: I have been using this laptop for around 8 years now I think with at least the last 4 running the setup described in the title. Never had any problems before. Roughly 9 days ago I moved into a new apartment with new internet and router, etc. At first both cable and wifi worked on linux, while on windows only the cable worked. Roughly 6 days ago I lost both wifi and cable on linux while windows has both working. A windows update (KB5032189) was installed on the 18th of November 2023 and .NET update (KB5032339) on 22th of November 2023.

At first I could ping to both my router and to 8.8.8.8 but not visit any websites. Also not the web interface of my router which is reached by ip address. But after messing with settings now it just says network unreachable. Sadly I didn't keep good track of what I messed with. I figured reinstalling might help so I got the latest Mint version (26th November 2023) on a live usb and started that up. It didn't help, so I tried the same thing with the latest Debian version with the same result. Note that I only ran from live usb and did not fully reinstall because I didn't see any changes.

Connecting and disconnecting of the ethernet cable is detected and a notification is shown. Wifi signals get found and when I connect I get asked for a password after which the connection seems fine. If I run Debian from the live usb and use my phone to check my router web interface it says one of the connected devices is Debian with 1Gbps connection.

I am at my wits end and mostly posting this in the hope someone has some idea of what to try.

No neither works on mint or debian, but both work on Windows 10

Thank you for your help. I also uninstalled the latest windows updates in case that broke something, but it did not help

visual spoke
#

also try seeing if updating the system fixes anything
sudo apt update && sudo apt upgrade && sudo apt clean && sudo apt autoclean && sudo apt autoremove

visual spoke
#

so its not a windows problem but a linux problem itself

#

and thats a pretty wierd issue, usually doing sudo reboot would just totally fix it for me when i could not get internet running

#

and if the wifi card is recent mint / debian might not be supporting it because old kernel

#

see if updating the kernel will help

I am getting a bunch of errors that it can't resolve mirrors

visual spoke
#

thats because it can't really connect to the mirrors so i guess you can only fix with offline fixes

#

Booting from a live usb also can't get a connection, which makes me think a hardware problem. But at the same time windows works fine

visual spoke
#

try seeing if reinstalling actually works but i doubt it will, remember to have a backup by the way

prime sun
#

No worries, I already put all the important stuff on usb sticks

#

Honestly was about time I upgraded my hardware anyway

Anyway I appreciate your effort, but I guess we can set this on abandoned

Tried the latest mint from a live usb, same issue of network not reachable

visual spoke
#

live usb =/= normal OS, by the way

prime sun
#

I see, didn't know that. In that case I might try doing a full install later tonight

@knotty kayak may I summon you for your support?

Installed debian since that is what I had on a usb stick. During installation configuring the network went fine, but after booting ping command still says network not reachable

I have some news, my fiber connection is broken so I have been working from a hotspot created by my phone. I got curious and tested if linux works with that and it does. I am starting to think that the router is blocking something. I am guessing that my mac address stays the same, is it possible that my router detects the same mac address for different operating systems and then gives an error for that?

not sure tho

Yeah I checked that. Wifi from phone hotspot works but wifi from router doesn't, though on windows both work

^disable wifi power management, Intel wifi doesn't like it

#

No, wifi_rvh or something like that

#

Currently using the moto g (4)

This command will disconnect you for a bit but will enable aggressive TX that may be necessary for that AP> sudo modprobe -r iwlwifi && sleep 5 && sudo modprobe iwlwifi 11n_disable=8

prime sun
#

modprobe: FATAL: Module iwlwifi is in use

lean cape
#

Seems the ISO doesn't have the iwlwifi.conf file that helps with making module changes

#

debian 12 ISO

#

Can it be a wifi problem of my laptop if it works fine when my phone is making a hotspot but doesn't work with my normal wifi?

lean cape
#

I would bet more on Windows causing issues. Can you use your Mint install?

#

You could use USB Tethering on the Mint install for internet connection

prime sun
#

I don't have a mint install available right now

Besides, I should be going to bed so I don't fall asleep at work tomorrow
