Also the question is interesting how you measured a time delay in 1 msec? The multimedia on Windows 10 msec has the timer and to measure the smaller period in 10 times to me it is represented impossible! Teach as?! My method of measurement is described above, there accuracy one frame, 240 times in 1 , and and the limit 100 fps monitors/vidjuh but yours turns out in 10 times better, with interest would hear the description how to measure a time delay in 1 msec on the PC...

Communication so-so: speed limit on  around 5 megabytes per second, not on  above 4 rarely rises. The provider gives 120 megabits and if by cable to the modem to be connected, basically it approximately so much and squeezes out. But the most terrible is unstable operation. All works as times normally,  to the modem within 3-5 msec, losses are not present, but losses of 10-20 % from time to time start to go, some packets go 50-100 msec 1-2 msec normal  to a router. WiFi AC 5 GHz. Problems are not present. Generally. If to speak about b/g/n and 2.4 GHz there all is bad. A problem that 2.4 GHz the signal is too well spread, the people bought to itself wild cheap devices which ignore standards, the order in time SLOTS and  wild capacity in the mismatched antenna with 11th stray harmonics. Therefore on 2.4 GHz that is called as a scorching heat is created. With a range of 5 GHz are one singularity: it well works only in one room. If it is necessary to cover a little it is necessary to put repeaters or mesh-system.

Re: Whether can WiFi be reliable?

The good fellow, only I began at once with routers. And a problem solved by setting of other router for 5 minutes Remaining samples with other routers did already simply so of curiosity out of working hours. Basically it proves that the problem was in a router. Now me not to force to conduct any more other researches. As connection of other router occupied 1 minute There is no time to understand with this crap on  1-11 Simply stick old (or on the contrary new under the standard/ac) a router and all works. I do not see any sense in points 1-11 for this reason. , Stanislaw K, you wrote: SK> Hello, loginx, you wrote: SK>>> the Videocamera?
