Hi @NotJohnAfterAll,

For your issue, please try the following suggestions:

    1) Make sure the Router is properly placed, it should be put in open area instead of inside a cabinet or shelf.
    2) Login the web management interface of the Router, go to Advanced > Wireless > Wireless Settings, change the wireless channel into another one.
    3) For 2.4GHz wireless client devices, adjust 2.4GHz channel width into 20MHz, for 5G wireless client devices, adjust 5GHz channel width into 80MHz or 40MHz to avoid interference.

 Hi @NotJohnAfterAll,

Please try the following suggestions:

1. Reduce the number of wireless clients and optimize the router’s position.
2. Set different Wi-Fi names for 2.4gzh and 5gha bands, and disable smart connect if the router supports it. 
3. Change 2.4ghz channel(1/6/11) and channel width(20Mhz). Change 5ghz channel (band 1: 36\40\44\48, or band 4:149\153\157\161\165) and channel width(20/40mhz)

If the above steps are not helpful, please collect information:

1. When does the issue start, and how frequent is it? 
2. How many devices experience unstable wireless connection issues, and what are they?
3. Which band has a dropping issue (2.4G or 5G)? 
4. Led status on the router when the internet drops? 
5. How do clients reconnect after a disconnection? Will they automatically reconnect, or do we need to reboot the router?
6. Does the Wireless Network name disappear when dropping?
7. When did you buy the router?

Hi@NotJohnAfterAll,

It seems that the router's Wi-Fi broadcast function may be abnormal. It is recommended that you contact local support for further help.
