This happens with firefox, chrome, chromium and wget. Upload speeds are ok. Downloads in LAN seems not to be affected. Only from the Internet (i.e.: speedtest.net with firefox/chrome/chromium or some big ISO files downloads). When booting with older kernel, i.e. 6.2.0-24, the problem disappear. My network card is a Realtek, see attached lspci output, and is using r8169 module.
