Problem connecting CP1525 wirelessly to my new router

[subaruWest]

I have problem connecting my Laser Jet CP1525nw printer to a new router. The router is the NBN smart modem Gen 2 provided by Australia Telstra. 

I had no problem connecting to the network previously with my old router. 

I've tried trick like this one but still with no luck.

I have also reset network setting to default and reset things from the beginning.... still no luck

I've tried contacting my ISP but they weren't helpful either.

Can someone please help me!!!

Hi,

What exact behavior occurs when you try to connect the printer?

There are many possible causes that will cause different errors, e.g you are not able to see the printer, any security or mac Filtering error, there are many possible causes so please provide some more information about the error to get some better understanding.

Thanks for your reply. Let me go thru what I've done...

I've connected the printer to my router with an Ethernet cable. Got the IP address of the printer.

I used that IP address to access the setup page of the printer on my computer. My Wi-Fi network does show up on the "Wireless Configuration" section. I selected my Wi-Fi network, put in my password. Clicked apply. Unplug Ethernet cable. Blue wireless light on printer just kept flashing. I clicked on the apply button again on the setup page, after unplugging the cable, came back with a "HTTP 0" message.

I have deactivated the ipv6 on printer as suggested by some posters in the forum.

On my router, I have made sure the 24ghz channel is not the same name as the 5g one. And disabled the auto steering. Once again, as suggested by some other posters in this forum.

Hopefully I've explained it clearly....

Yes, you explained it perfectly fine indeed!

From the Setup menu of the printer please select Network Settings, click on Wireless Settings, and then on Run Wireless Test. May the report indicate any specific warning or attention?

I'm finding some hard time finding any documentation about your router, contacting your service provider might be a good idea, as they are aware of their router capabilities and limitations.

On the matter of security, I would ensure that WPA/WPA2 is enabled, in case the router supports WPA3 it is not supported by such an older model.

Also, do you have a single router from them and not any additional WiFi boosters? from their description to the Smart Wi-Fi feature it seems like any kind of SON or Mesh technology which might prevent a wireless connection for the printer:

Also, I would make sure your printer firmware is up to date with a temporary Ethernet connection:

As well, I suggest verifying your router is fully up to date with its latest firmware.

Hope that may help,
