I am new to Linux. Immediately encountered the problem of very weak wifi signal, that i haven't on windows. I've already seen the solutions for HP laptops, and none of them worked for me. Tried to change kernel as well (I heard that 5.15 version is kinda buggy in this context), but still nothing. I got following output for lshw -C network command:

  *-network

And for lspci it is

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)

I thought that updating WiFi driver would help, but saddly there's no version I can update for.

I would be incredibly grateful if someone could help

UPD 1. Result of the terminal command: nmcli device wifi list is following. Where Androidha is my phone on which I turned on the hotspot and I literally placed my phone on the laptop, and it's still, not even close to "strong signal", the phone itself is connected to one of these other WiFi. Two other routers are in adjacent room.

  • I wish I had the same WiFi card so I could help there, but +1 to your question to hopefully help you on your way that someone here might have figured this out as I have seen others asking. However, that being said, I did notice that you are using the r8169 driver on the RTL 8168 card. That driver is very flaky on the 8168 card and seems to be the default one chosen for that card. You can fix it by installing the r8168 driver. sudo apt install r8168-dkms – Terrance Nov 05 '22 at 21:32
  • Unfortunately, it didn't work. But thank you for your responsiveness – dradrext Nov 05 '22 at 21:54
  • My comment above won't fix the WiFi, but it will help your ethernet connection if you use it. – Terrance Nov 05 '22 at 21:54
  • How weak is it? Please edit your question to show the result of the terminal command: nmcli device wifi list Please redact all the MAC addesses with XXXX. Welcome to Ask Ubuntu. – chili555 Nov 06 '22 at 00:57
  • From your question "(I heard that 5.15 version is kinda buggy in this context)" Do you have a link I can go to to read this for myself? – David Nov 06 '22 at 07:19
  • For example this https://askubuntu.com/questions/1403954/wifi-issues-in-ubuntu-22-04lts . But it's not the only thread discussing this problem, all other are on different pages. – dradrext Nov 06 '22 at 09:19
  • What is the output of uname -r? If you read through that link that you posted in your comment they are stating that the WiFi signal seems to be fixed in Kernel version 5.15.0-33 and possibly newer. – Terrance Nov 12 '22 at 03:05
  • Well not for me. I tried 5.17, 6.05 and 5.13 kernels version. Nothing had an effect. – dradrext Nov 13 '22 at 08:02
