    Over-aggressive band steer 2.4 GHz to 5 GHz?


    One of my users has recently experienced bad WiFi-connectivity. At boot, all was good; though after some time the number of quarter-circles indicating field strength went down, and connections became bad, at times making video conferencing MS teams lousy to impossible.

    I couldn't find anything wrong with the AP, a professional EnGenius dual band. Other users had no problems.


    It took me some time to find the reason: Her machine, lenovo Helix 2, with Intel Dual Band Wireless AC 7265, running latest driver and regularly updated W10, connects to the AP at boot through the 2.4 GHz band. Sooner or later it switches to 5 GHz, though the field strength is lower -70dB on 2.4 versus -83dB on 5 GHz. When, under certain circumstances, the 5 GHz get's even lower, the client disconnects. At least I have never seen it returning to 2.4 GHz instead. Except with a shutdown.


    Since she didn't see this earlier, I took the guess that at some moment the offload from 2.4 to 5 was made more aggressive in either the driver or W10. so aggressive, that it steers from 2.4 to 5, even at a loss of field strength by more than 10 dB and seemingly never back.

    For further exploration, I created an additional SSID for her personally that is only available on the 2.4 GHz band. Since then, everything runs smoothly, again.


    Last not least: band steer on the AP has always been disabled.

  2. How Do I Access 5 GHz Band On AC1750?

    I don't see a screen like the screenshot you posted allowing selection of 5 GHz in my Security Page. This is what I see, and there is no option to connect to 2 GHz or 5 GHz.

    I did login into the router. It lists the 5 Ghz band correctly, but is doesn't show up on Network Settings. Therefore, I cannot connect to it. I would think it should be there too, but it isn't as far as I can tell. The only entry in Network Settings is the 2.4 GHz one. What can I do to get the 5 GHz band recognized in order to connect?

    5 gHz Wifi

    I installed a new Cable Modem Router that has dual band, 2.4 gHz and 5 gHz wifi. Everything works fine on my cell phones but when I connect to the new wifi, my computer does not see the 5 gHz wifi. I am using Windows 10 on a HP Pavilion g6. The computer
    is more than 5 years old. Is there a way to get the computer to recognize the 5 gHz wifi, which is more reliable than the 2.4 gHz?
