    Strange FiOS Quantum Gateway 5 GHz Band Behavior


    I am using the Verizon FiOS Quantum Gateway router. I am getting some strange behavior when trying to connecting to it with a Surface Pro 4 using the 5 GHz (either mixed N/AC or AC mode, fixed channel 40) band. Routing to the Surface seems to fail regularly as evidenced by web sites "page not found" that is immediately rectified by a page refresh in the browse -- so I don't think this is DNS. Transfer rates and speed tests are also intermittently good and very bad within the same test (fast, then stop, then resumed).

    Using two WiFi analyzer apps, I see two 5 GHz/AC networks: one has the SSID I set (which is different than the 2.4 GHz band) and one that is hidden. The interesting thing is that the BSSID for the non-hidden network is C8:A7:XX:XX:XX:XX:68 and the BSSID for the hidden network is CA:A7:XX:XX:XX:XX:69 -- not the similarity. Changing channel on the non-hidden network changes it on the hidden network. The C8 BSSID is Verizon Business but the CA has none listed and a search for it on the web produces no registration.

    I do not get this behavior using the 2.4 GHz N band. Web browsing is very fast and speed tests normal.

    From the behavior it looks to me like the Quantum router is broadcasting two BSSIDs (one shown, one hidden) for the SSID I have set in it, and this is causing the routing to get messed up.

    Can anyone offer some information to help me understand what may really be going on and what I can do to fix it? Thanks.

    Could Windows Update have replaced the Wi-Fi driver with one that is not working properly? Try downloading latest driver and install it. If there is no Windows 10 driver, try that for 8 or 7. Then hide any driver updates so it won't be replaced again.

    You could be experiencing the slow WiFi issue with the SP4. Try the fix discussed in this link

    Doubtful -- The Surface Pro 4 was just released and I bought it at a Microsoft store. It had been built just a week before. There are no driver updates listed in the update history.
    EDIT: Sorry, it appears you may be right that it is a driver issue. MS has acknowledged it and we're waiting for a fix. sciencegeek pointed me in the right direction.
