  • 1.  how to verify 5GhZ network speed increase

    Posted Jun 30, 2023 11:33 AM

    Hello, a week ago we increased our link from 100 to 300 MB with this looking to improve the connectivity of the users, it happens that certain APs do not deliver the speed that we expect, that is why I am making this query, in the Aruba controller some configuration must be changed to that via 5 GHZ can users navigate at that speed?

    Aruba 7005 controller

    I appreciate your help

    If you only had 100 megs at first, the easiest thing you could so is a speedtest from your client to determine the throughput.  If there is a 100meg bottleneck (the port on switch the AP is connected to is 100 megs) the client would get no more than 90 megabits of throughput.  You should make sure that the controller and the access points are connected at 1 gig for full throughput.

    Start here with what you can expect, before ISP line/switch/Ap-model considerations come into play: https://mcindex.com/

    which is the theoretical WI-FI speed, expect 50% of this.

    (Find your favorite Ap's maximum values in a horizontal axis, and a client device connection mode in the vertical)

    and of course as in the previous post, the lowest common multiple of ISP speed, to ~90%, i.e. of the 300 Mbs, > 270 Mbs. Which means that you need at least 1 Gbs, on all connected devices [~10 Gb on central one > LAN], and corresponding transaction capacities in other infrastructure to process this in the number of clients to be served, and always allow JUMBO frames [9k]. Then the client/AP equipment capacities in relation to the MCS table will give you theoretical/practical speed capacities and user satisfaction.

    Do not exaggerate the AP load beyond the SSID default of 64 clients, if the latest and greatest APs are not used, consider lowering it, and increasing the number of APs, in crowded areas, and look over the number of SSIDs, and look over the bandwidth (20/40/80/160Mhz) settings..Good luck
