How to fix wireless issues on my MacBook with Linksys Velop Pro 7?

I understand that Mac's wireless connection to that particular network is unreliable or intermittent.

Try this: open your Mac's System Preferences / Settings > Network, and choose the Wi-Fi interface at the left. Click the Advanced button. Under Known Networks, choose each network that appears in the list and then Remove From List.

That action keeps your Mac from attempting to connect to any other network any of your devices may have connected to in the past — an action that may be time-consuming or otherwise preventing reliable connections.

Then, reconnect to your Linksys network.

If your macOS version is up to date (macOS 13.7.1 is the latest) then I'm out of ideas, other than to suggest using EtreCheck which could conceivably reveal something interesting.

Otherwise contact Apple, here: Official Apple Support. Perhaps they will have some other suggestions.
