Same result with new (10 Gb and old 2.5 GB) network card. Tried 3 different CAT 7 and CAT 6 cables with 1 Gb and 10 Gb output on the router.
It seems that the fault lies with the router.
What else can I do?
Dreizackstern Please uninstall the Norton crap, these “virus protection programs” cause more problems than anything else and are no better in terms of security than the free Windows Defender
But with Norton you have a hidden cryptominer, which Windows Defender “unfortunately” can’t offer 🙂
And as further completely unnecessary collateral damage from Norton and similar “security tools”, you will then realise at some point that the new creation of new mailboxes to be integrated via IMAP in Windows e-mail programs such as Outlook or Thunderbird will no longer work. Outlook or Thunderbird will no longer work, because various third-party security programmes will then try to hack into the email traffic between the server mailbox and the email client via a man-in-the-middle attack, which will then be interpreted by various mailbox servers as an actual malware attack with the resulting denial of service.
Of course, in the event of problems caused by Windows-external security programmes, it is then purely up to the intuition of the respective customer to find out how to get out of their unfortunate situation, which is why the clear prevention solution is the best solution here:
Never, under any circumstances, install any third-party security programmes and then possibly also pay for the collateral damage they cause, which cannot really be clearly assessed.

Dreizackstern Packet Errors indicate a problem outside the computer, such as a faulty cable. With packet discards - and you have a lot of them - the cause is usually the computer itself. This could be a faulty driver or an overloaded network card. I would be surprised that higher-level software such as an antivirus programme intervenes so deeply, but it is possible. Like the others, I would advise you to remove Norton completely, it causes more trouble than it helps - regardless of the speed test “problem”.
If this does not bring your speed test results or the dropped packet counter to the expected values, check whether you have installed the latest driver for the network card. If that doesn’t help either, you could try deactivating the various offload engines of the NIC in the driver settings. But before you do that, please post an interim status here in the thread.
Have you tried turning it off and on again?
Thank you for your reply. I have done the following in the meantime. Installed new driver for the Tp-Link TX 401. Uninstalled Norton 360.
Result: Download speed has increased slightly to 3.5 - 3.9 Gbit/sec. Upload good. No more dropped packets and 20 errors when sending.
Norton installed again
Result: Download speed has dropped to 1.6 - 2.3 Gbit/sec. Upload good. No more dropped packets and 20 errors when sending.
….keep on rockin'
Dreizackstern Thanks for the feedback. As you can see, Norton 360 obviously has a negative impact on the speed test result. As far as the reputation and benefits (not) of this software are concerned, my forum colleagues have already written enough. You have to find out for yourself.
What surprises me is that no more discarded packets are reported, but the speed is obviously still limited by something.
In the settings of most network card drivers, you can activate or deactivate various offload engines (e.g. various checksum offloads, large send offload etc.). These offload engines should reduce the load on the computer’s CPU, but it has often happened with cheap NICs in particular that they are poorly programmed. You could therefore try deactivating one offload engine after the other and see if the speed test result improves.
In addition, have you ever tried a different speed test server and measured at different times of the day and night?
And last but not least, an alternative solution: forget about speedtesting and enjoy your online life at whatever speed your setup allows. Want to bet that you won’t even notice the slightest difference between 1.6 and 10.0 Gbit/s in daily operation?
