Why won't my HP 135wr printer connect to 5GHz Wi-Fi?
The HP Laser MFP 135wr's wireless module only supports the 802.11 b/g/n standard, which operates exclusively in the 2.4 GHz frequency range. Routers that broadcast only a 5 GHz network (or have a combined name that prioritizes 5 GHz) may not be visible to the device. Ensure that a 2.4 GHz network is available.
How to find the IP address of a printer on the network?
To print a network configuration report, press and hold the Wireless button on the control panel for 5 seconds until the lights flash. The printer will print a page with the current IP address (e.g., 192.168.1.45) listed in the Wireless section.
What to do if the computer sees the printer but does not print?
Remove the device from the printer list in the operating system and add it again. The problem is often related to the port: when the router changes the IP address, the old port becomes inactive. Using the device name (WSD port) instead of the IP address during installation can prevent this problem in the future.
Can the HP 135wr be connected to a guest Wi-Fi network?
Technically, this is possible if the guest network doesn't require web login (Captive Portal). However, devices on the guest network are often isolated from each other, making printing from a computer or phone impossible. It's recommended to use the primary network.
