I can connect to wifi but not to Internet

General system Kernel, boot, graphics & hardware

I made a live USB from an ISO which I downloaded yesterday. It can connect to my wifi but not to Internet. It worked fine before I decided to reinstall the OS.

I looked at this: WiFi connects, but network is not working, no internet (after last update)
nordvpnd is not installed on this machine, so it’s not related

I looked here: https://bbs.archlinux.org/viewtopic.php?id=208855
But my problem seems to be different because:

ip addr

Any idea?

Can you ping the router at 10.0.0.138?
Can you ping endeavouros.com?
Check the router’s internal settings to make sure it isn’t blocking devices and/or specify the ip address to hand to your system.

What is your WiFi device?

update:
Sometimes the internet connects well, sometimes the connection is very slow and most of the times I can’t connect at all. When I try to ping 10.0.0.138, the packets are either lost or it says: “Destination host unreachable”.

After a long time, I received a good connection, so I ran yay to update the packages. After that, the problem didn’t appear again. Before I got this good connection, I tried to connect a different WiFi.

My WiFi device is Realtek RTL8188EUS.

Did you try

8188eu-aircrack-dkms-git
6

No, I didn’t install any additional drivers.

7

Did you check with your ISP to see if there are any network problems? Did you power cycle your cable modem (if that is what you use)?

8

I was able to access Internet well from my other computer connected to the same network. So network problems are out of consideration.

9

Is the problem still happening?

11

It is not happening anymore.
