Windows internet speed test

After switching the Encryption Type in the Wireless Network Properties from AES to TKIP, I get downstream speeds of 22+Mbps again. Pings and upstream speeds are basically unaffected (11ms -> 10ms, 0.9Mbps -> 1.0Mbps).

This is reproducible: after switching back to AES, I get the old downstream speeds again.

Explanations are welcome, all of this makes no sense to me.

When it was still fast a few days ago, was I still on TKIP? Then what switched me!? Or why is AES suddenly so much slower than TKIP? Why is it just as fast on other networks?

Edit: A bit a research made me believe that by switching to TKIP, I implicitly also switched from 802.11n to 802.11g (because TKIP is not allowed on n due to its security problems). That would also explain why I'm now seeing a connection speed of 54Mbps. So now the question becomes, why does g work, but n stopped working?

(Mind you, I still prefer a connection speed of 54Mbps with 22Mbps actual throughput over connection speeds of 130Mbps with 2Mbps throughput.)

Try adding the option:

-4

Also, try to run a speedtest:

wget https://raw.github.com/sivel/speedtest-cli/master/speedtest_cli.py
chmod a+rx speedtest_cli.py
sudo mv speedtest_cli.py /usr/local/bin/speedtest-cli
sudo chown root:root /usr/local/bin/speedtest-cli
speedtest-cli

This will output, among others, your download and upload speed. By the way, are you using wireless or ethernet?

You can also try an alternative to wget, for example HTTrack, aria2, cURL, etc.
