HDMI Connected to External Monitor to My Laptop Causes Internet to Disconnect.

Hello. I need help with radio wifi signals, please. Thank you.   What is the problem? I have discovered the cause of my internet dropping. Whenever I’m connected via my HDMI that links my laptop...

    Fixed.

    The original problem was disabling the 2.4Ghz about a week ago but despite re-enabling it, the problem persisted. 

    Spent the day [04-06-2024] disabling channel optimisation. Enabling it. Disabling it. Enabling it etc. turning off the switch of the hub itself.

    Looked at the connected devices channel list on the Wi-Fi analyser app on my phone and for 2.4GHz. Then on the Hub Site 192.168.0.1 only choosing the best channel with channel optimisation disabled. Then Enabling it. Disabling it. Enabling it etc. Letting it time out.

    Possible problem was despite the channel optimisation being on there was maybe still a problem with it choosing the channel…it wasn’t actually choosing the most optimal one. Turning it on/off etc maybe has helped.

    Also I removed the Bluetooth razer stuff last night from my PC, removed the USB razer and have returned the mouse.

    Also Razer Cortex is not the active power plan anymore.

    Thank you to everyone who shared their thoughts, tips and advice.

     

    My current settings on the Hub/other settings following the fix:

Have you identified which wireless signal (2.4 or 5GHz) is being affected by the HDMI connection? Or is it both?

Have you identified which of the two bands (2.4 or 5GHz) your laptop is preferring to connect to? You should be able to see that in the connected devices section of the hub interface.

You can experiment by turning off each band in turn (either on the wireless adapter or on the hub) and seeing if there is any change.

Have you also tried adjusting the refresh rate of the monitor to see if that has any effect on the interference (if that is what it is causing your problems)?

    Another interesting discovery: Having the HDMI connected and the laptop lid up so there's two displays [my external monitor HDMI connected to the laptop] and my laptop screen itself, the internet icon shows for much longer and is connected BUT even when it is connected, it's unable to load anything often

    [Netgear Extender]Having the HDMI connected and the laptop lid up so there's two displays [my external monitor HDMI connected to the laptop] and my laptop screen itself, the internet is much more stable for much longer as if there's no issue it seems...

     

    Hey, thank you for the reply.

    I'm not sure what the 2.4GHz and 5GHz mean and their differences. 

    I have a Netgear extender also and this seems to connect for longer with the HDMI but it does eventually disconnect and then reconnect, but it's not stable with the HDMI connected.

    No, I'm not sure what GHz is causing the issue.


    Have you identified which of the two bands (2.4 or 5GHz) your laptop is preferring to connect to? You should be able to see that in the connected devices section of the hub interface.

    2.4GHz - for my non-EXT whenever I'm connected to the non-Netgear Extender 

    5GHz - for my EXT whenever I'm connected to the EXT Netgear Extender 

    You can experiment by turning off each band in turn (either on the wireless adapter or on the hub) and seeing if there is any change.

    I've been doing this, but I don't really understand enough about it for the combos to work. I've tried many different combos but unfortunately, there is no change.

    Have you also tried adjusting the refresh rate of the monitor to see if that has any effect on the interference (if that is what it is causing your problems)?

    This seemed to work for a few seconds quite well - but then suddenly the connection dropped again, unfortunately.
    I've set it 60, the maximum one.
