Slow network - new Ubuntu
by Mantra from LinuxQuestions.org on (#5JMRN)
New Ubuntu install, and the network is really slow.
Sometimes websites load fine, and not too slowly... but usually they don't, especially on first load. Thought it might be something related to dns errors but not sure. I've turned off IP6 but it doesn't seem to have changed anything.
But I have found this, running the following:
Code:ping -M do -s xxx 8.8.8.8gives some strange results (replacing x with numbers).
Using 8.8.8.8, xxx can only go up to 50 (ping times about 45ms), any higher and it times out with no reply. But isn't that number the MTU, which ought to be about 1470, not about 50?
Changing the server to 1.1.1.1 gives normal results, ie it works up to 1472 with no errors.
Not sure if that's related to the slow and intermittent network problems.
Network access is through a 4G dongle, but that works fine on a separate debian system, so I'm pretty sure it's a software config thing on the new box.
Any suggestions?
