But he posted a second screenshot that showed that his upload speeds were consistently around 20Mbps no matter the time of day while his download speeds fluctuated a lot more.
Like I said, anecdotal. All of those speeds tests where done in the span of 10 minutes past midnight, in (which is safe to assume) the same location and with extremely great signal strength/LOS.
The problem with upload speeds in the 2.5 Ghz band is that the UL speeds dramatically fall off whenever you move away from the tower. Good speeds are possible, but on a few select areas near towers.
