    @Kari,
    I was just testing transfer speed of same file and same PCs, this time over a wired LAN 10/100. As a result I learned today the last small detail about "Speeds".
    About the WLAN speed, there is no doubt that I am getting 62,5% gain over the specified speed of the router, that would not be able to pass beyond the 8MB/s or 64Mbps.

    You are looking at this wrong. If you are using Windows File Transfer guess what your network speed is, you are going to get incorrect information on how fast the 1's and 0's went between the machines. There is actual software that you use for getting your true network speed between two machines.

    There is nothing wrong with your network. Everything just happened to be aligned in the Heavens at the same time.

    @bro67,
    OK. I do not agree with that Windows speeds are inaccurate. In picture above, you see 98,5 Mbps as receive speed and 2,4Mbps Send speed and that is very close to 100Mbps, the max for a wired LAN 100Mbps . The speed of 11,3MB/s is the overall average speed, and that I also confirmed to be accurate by the Stopwatch test as I said above.

    After researching / thinking / doing "maths" around I come to the conclusion that the Router Hardware must be fully N600 capable, there is no other explanation, and I also know why I can not get the full N600 speed.
    So, I will mark this as solved.

    You're doing your "maths" wrong!

    The maximum throughput of a 300 Mbps connection is (300,000,000/8)/1048576= 35.76 MB/s. The observed value of 12.5 MB/s is meh, as in no big deal.

    Sorry but it is not. See kludge's post. It is a known issue with how Windows measures packets when transferred. It is going to be an estimate of how fast or slow the packets are being sent between machines. In order to find out the real network speed between machines, you have to use the software that you place one part on the Master and one part on the Slave and then it runs packet testing to where it starts slow then builds up until it starts seeing errors, then comes back down and stays there to give you a final report. You also have to factor in on the hardware for both sides and any interference on the wifi, along with the CPU on the Router, which the majority of the lower speed units have very slow CPU's and a small amount of RAM. Check out smallnetbuilder.com for how the magic works.

    this is a good Tool for converting mbps to mbs etc....no math needed.

    300 mbps

    100mbps Ethernet

    I pickup my calculator AND YOU are right!
    Unfortunately, that 300Mbps and your output of 37.76MB/s are not meaning the same "thing".
    Actually the 300Mbps will allow a Max DATA Transferrate of 25MB/s, so far theoretically.

    Now, the problem I am facing is that I can not pass the 8MB/s when using a 1xN300 adapter and 1x 802.11AC , or 12,5MB/s when using 2x 802.11 AC adapter with the same router N300.
    I have switch the Adapters among the computers and the result is the same.
    Now, either the router is crap and is only working at max 130Mbps or the "maths" around are false, something similar to DVD Write/read speed.

    Why are you still dwelling on this. Any kind of data transfer is not going to be a straight line for packet transfer. In reality it would look like a Sine Wave, just like when data is transmitted as analog with dial-up modems.

    Every packet is going to be a different size, a different length, may have to be retransmitted due to it did not meet the check requirement when the receiving end tries to verify what the sending side stated what size the packet would be and the length.

    Your router is not crap, it is that you are trying to look at it in a scientific method instead of a theoretical method.

    I think I found the explanation for the 12.5MB/s and 300Mbps connection:
    The 300Mbps is the overall available Bandwidth and it it will be shared with all connections, so 12,5x2=25MB/s and that is the max. for 300Mbps.
    I think like that is correct.
