Upload delayed response with DSL router in SpeedTest

[_sem_]

I'm trying to troubleshoot a slow web browsing response issue on a 10/.85 Mbps DSL connection using Thomson TG782 in central Europe. I'm well aware 10/.85 isn't exactly world record class. The curious thing is that while the final speedtest.net UL/DL speed figures are close to the declared values at ping around 25 ms, the DL line during the measurement raises quilckly and is mostly almost flat, while the UL line takes a few seconds to move from zero, then stays around 0.5 for some more seconds, and finally reaches .8 by the end of the measurement, repeatably. Roughly the same on either LAN or wifi connection to the laptop. Is this normal on DSL lines?

Further, I've connected another router, WAN port to one TG782 LAN port, and the UL response gets even slower and doesn't reach .8 until the end of the speedtest measurement...

That's fairy normal in my experience. I think it's caused by the way the test is performed, although I think the effect is being exaggerated by your low UL bandwidth.

Tnx, thought Speedtest was realiable but seems not, watching ethernet performance in Win10 Task Manager when doing big file UL/DL
