Since some days I had problems to connect with the internet. After checking the net speed and the line quality with the pingtest of Ookla I found that the computer I always use had a line quality between D and F. According to the test side barely usable for a lot of programms. (computer C)
Did run the test also on a reserve set with a fully updated Tumbleweed and much to my surprise with that machine I have a very good line quality A or B. (computer A)
Having a notebook with (not fully updated) Tumbleweed gave me a surprise C line quality. (computer B)
All computers are connected to the same router. Cable length same.
With every repeat of the ping test the results are same. All connectors are clean and according to my logic, the results of all three computers should be same.
Could some body come up with the reason or reasons for this troubling result.
Ookla is crap. It relies on so much java and java script and Flash that its results are horribly biased by the processor speed. Avoid it, and find another simpler speed test site. Maybe http://www.speedguide.net/speedtest/ or something. That said, you can have different results on different machines based on the NIC in that machine. So check that each nic negotiated the same connection with your router, sometimes various nics will not reliably get a duplex connection. Other than that, and the twisting of the aforementioned wires, if all your computers are on the same router, then any difference must be inside your house, and ratty cables, difference in ports (try swapping ports on the router), or link speed might have an effect. But you have to get rid of things that are processor speed dependent, because nothing in a speed test should burden your processor. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
