Devices are slow to connect to WIFI after restart

This issue has occurred ever since I switched to the CAX30 from the AC1900.

When the CAX30 is rebooted or if there is a power outage, devices take a long time to connect back to wifi.

It takes hours (more than 12) to have all the devices in my home connect to wifi. The phone for instance shows a massage saying "unable to obtain IP address" when trying to connect.

There isn't a way to force the device to connect, except waiting until it does.

Additionally, I've moved to a new address and the problem still persists. This occurs with both 5G and 2.4G networks.

It almost seems like the CAX30 is having an issue assigning IP addresses to devices that are trying to connect.

I have attempted resetting the device, and changing the credentials (wifi name and password) without luck.

Is this a hardware problem? is it the service provider?  any solutions?

 

Thank you!

A couple of suggestions, some you may already have in place.

Disable Smart Connect – in Advanced Wireless Setup.

Setup different SSIDs for the 2.4 GHz and 5 GHz bands.

Turn off Auto channel selection on both bands.  Select channel 11 for 2.4 GHz and channel 48 for  5 GHz.  Your radio frequency environment may push you one direction or the other.

Once a device like your IP phone has been assigned an address, write it down and add it to the address reserved list on the router.  Under Advanced Setup LAN Setup.

Disable 20/40 MHz coexistence.  Under Advanced Setup Wireless Setup.

If your ISP support it, enable IPv6.

These are all fine tuning steps, and some may work for you, and some may not.

There are a lot of variables.  The type of building, wood walls, metal studs, brick, concrete, etc.  Single family dwelling or multi-family with a lot of other radio frequency signals or not.  The various items in your inventory trying to connect to your Wi-Fi.  Computers, phones, smart speakers, IP cameras, smart thermostats, smart TV’s, robot sweepers, light bulbs, all of varying manufacture and age.  The workload on your router can be significant and all take time to sort out after a restart.  Many of the fancy “features” on the router add to the workload and in the end are not worth cost in overhead.
