Title:
Erratic ethernet connectivity and icon
Status in network-manager package in Ubuntu:
New
Bug description:
Ubuntu 18.04.4 LTS
Installed: 1.10.6-2ubuntu1.4
Candidate: 1.10.6-2ubuntu1.4
Version table:
*** 1.10.6-2ubuntu1.4 500
Expected behavior is a stable high-speed internet connection when usb
tethering with an Android phone.
Instead, for the past three months, since covid slowed down internet
connectivity on Jio telecom in India, my Ubuntu internet connectivity
has become erratic. In the early morning before 6 AM when I tether an
Android phone to my laptop the internet connectivity indicator in the
upper right-hand corner of the desktop shows the normal three boxes in
a triangle and has decent speed. As network traffic increases the
indicator turns to three gray boxes with a question mark in the middle
and connectivity speed remains decent for a few websites, such as
YouTube, Google Search and some others, but connectivity stops for
most websites. Chromium, Vivaldi and Firefox browsers show the
following error for such sites: “This site can’t be reached.
askubuntu.com’s server IP address could not be found.”
Oddly, in tri-booted Win 10 all websites open reliably 24/7, though
sometimes at slow speeds. In Fedora 31 on the same hardware the
behavior is identical to Ubuntu. I’ve tried changing the DNS settings
in Ubuntu to use Cloud Flare, Google and even the DNS settings in
Windows, but to no avail. On Ask Ubuntu there were no helpful
comments except a suggestion to file a bug report.
Ideally, connectivity without "unable to connect" errors on most
websites should be available always.
BTW, when I allowed data to be collected for this bug report it was in
the early morning, so the connection was working properly and the
network icon was the normal three boxes in a triangle with decent
speed. If need be, I can send more information later when the "unable
to connect" errors occur from Windows 10, or via email, which always
works.
