Agreed. I get pretty much the same results when doing testing directly on the computer though. Teamviewer doesn't appear to have much overhead. I've tested this on a couple of computers, all wired, and all with the same results.
By default, iPerf sends to the server. So my 5.5 Mbps throughput was only my upload speed. When I ran iPerf in reverse mode (-R) is downloads from the server. I wasn't getting good results from a single TCP session, but when I increased it to 10, i was getting the results I was expecting (47 Mbps). If you want to try these tests for yourself you can use these commands for any public iPerf server:
Upload test - iperf3 -c iperf.he.net
Download test - iperf3 -R -c iperf.he.net -P10
I do not know what the bandwidth limitation is with this iPerf server
I recently upgraded to the highest speed that att has but continue to have troubles using my fax machine and a securuty camera....It was working great after the upgrade now my fax only passes the test number if I disconnect my security camera,,, somehowe something has gone wrong interesting enough it works the minute i call att then doesn't the minute I get off the phone wierd makes you suspect they don't want me faxing ha ha the fax just says communication problem or receient busy .Am I crazy or should my band width needs be totally taken care of with the 24 Mbps I am supposed to be getting earlier today My speed on a speed test sayis under 18Mbps after talking to att and them adjusting my modem????I now have around what I should have 24 Mbps so what's up here?
