New router, same SSID but a few items wont connect

DullGreyGuy

My router type thing at home was starting to get flaky and given its involved in home security, home entertainment etc decided to replace it with the latest version of the same Linksys Velop family. Set up the new nodes to mirror the SSID and password of the original and 28 of our 35 devices have automatically connected to it without needing any intervention. 

The 7 exceptions are some smart bulbs (but other identical ones are connecting fine) and it would be a real pain in the backside to have to reset them all and reconnect them... anyone have any other suggestions on how to get them to reconnect without resetting? Done the obvious "turn them on and off again".

Are the devices that don't connect in a certain area?  Do they connect if they are moved closer to the router?  It could be a difference in Wi-Fi broadcasting coverage.

no, they are in two different clusters of which the larger is in the same room as the router and other items are both closer and further and connect property.

any on static IP's?

There aren't any static IPs

Check the DHCP has enough entries.

Do you have both the 2.4 & 5g bands turned on - my smart bulbs only connect on 2.4g

Is the security protocol the same - WPA2 - PSK etc....?

If some devices of the same type work then it is possibly an IP address conflict, (rather than a protocol/band issue)
e.g. the non working devices are using IP addresses assigned by the old router, but the new router has assigned the same addresses to other devices (many home routers don't prevent this).

This usually sorts itself out after restarting the offending devices (which should cause them to ask for new addresses), or after a few hours.

Is this still a problem a day later?

Thanks for the suggestion... same problem about a week later with the devices (but not the router) being turned on/off many times

2.4hz and 5hz are both active and it initially copied the original setting with was WPA2... I did after a day or so try changing it to WPA2 & WPA3 and that didn't change the situation for any devices

How would I check this @getmore4less? Linksys claim each node can support 50 devices and we have 2 nodes and less than 50 devices in total

Do the 2.4GHz and 5GHz bands have the same ID? If so, temporarily disable the 5GHz and try to connect the bulbs to the 2.4Gz band before turning the 5GHz back on.
