HP DeskJet 3755 disconnects from wireless constantly still

[thewhackness]

Mellow Greetings,

I got this model ( used) about a week ago. Though I saw some initial problems people were having with this particular model, I jumped on YouTube and was able to get it connected, which gave me hope; however, 2 minutes later, I was met with the same complaints I've seen posted online about the printer constantly dropping from the wifi. I see the printer in the setup window; however, it's got the greyed-out circle with the minus symbol followed by unavailable. I've tried several times backtracking to what got me on the first time, but the same thing keeps happening. Has anyone had success bringing it back online to print? On day two, trying to work through this, but it seemed like a waste of time, it would be nice to have a printer that's not huge here in my shop so I could print. Any help or success stories? the HP chatbot doesn't help, and I feel like I've done everything at this point.

Welcome to the HP English Community --

DeskJet Printers are the economy printers in the HP line -- nice for general printing needs.

DeskJet printers typically do not print Borderless, they usually require a larger margin along the bottom edge, AND they can be particular about how they are connected to a network.

Add the following:

This model series of the DeskJet line only connects to Wireless on the 2.4GHz frequency.

If your network forces both 2.4GHz and 5GHz onto the same SSID named network, the printer might catch the 2.4GHz band at initial connection but then fall off the network -- for example, when / if the frequency on the router is shifted to 5GHz (perhaps due to traffic).  The printer cannot find its way back onto the network in this case.

If you understand your network and your router's configuration, the following will seem easier than if the network and your router's configuration are a mystery. 

The information is not meant to be obscure --

To a large extent, the complexity needed to manage multiple bands / frequencies is inbuilt to modern networks and routers.  Not all devices are so forgiving and require particular settings to connect -- and stay connected.

User Guide

Review Chapter 7 - Connect your printer - Starting on Page 55

Review how to set the printer back to network defaults - Page 62

Reminder

Many printers, including this one, might falter (fall off the network) if the network is configured (on the router) to run a single SSID named network for both 2.4 and 5GHz .

If possible, create a separate SSID named network for each frequency -- connect the printer to the SSID named network for 2.4GHz.  If you need help, ask your Internet Provider to help split the SSID named network settings by frequency.

What else?

Alternatively, consider using Wi-Fi Direct (explained in the printer's user manual, starting on Page 59).

Dual Band Network - Considerations

Reminders 

Do not ignore your router --

A router that is weak, outdated, poorly located, or incorrectly configured can cause all sorts of odd network behavior issues.

If the printer supports it, connecting using Ethernet is generally a better choice.

If your router supports it, create a separate SSID named network for each frequency.

Connect the printer to the SSID network you want the printer to use on the network.

Wireless

Some printers, particularly older models, only support Wireless at 2.4GHz

Some printers support Wireless at both 5GHz and 2.4GHz – but not at the same time

Regardless, if the printer won't work or cannot connect to your 5GHz SSID named network, connect to the 2.4GHz network.

If you are running a Dual Band Network,

 Check that the router is set up to broadcast all frequencies it supports.

Next,

If your router supports it,

On your router:

 Create a separate SSID named network for each frequency supported by the router

 What?  Create one SSID named network for 5GHz and one SSID named network for 2.4GHz

and

 Connect the printer to the SSID named network on the frequency / band you want it to use.

In general,

• 2.4GHz is less fussy about obstacles and supports a longer distance (separation) between router and device (printer)
• 5GHz is faster

Use the HP printer Embedded Web Server (EWS)

NOTE:  Find printer IP address

Section Open the EWS over a local network orientation

Ethernet

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Tab Network > Wired (802.3) > IPv4 Configuration

Wireless

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Tab Network > Wireless (802.11) > IPv4 Configuration

As Available:

Tab Network > Wireless (802.11) > Advanced

Network Interface on / off, Network SSID name, Security Settings, Passphrase / Password

Select and connect to the correct SSID / network name for the bandwidth you are using.

Note:  

It is not mandatory that you use a manual / static IP address. 

Doing so can improve stability.

I'm sorry, but none of this worked for me. And this is very alarming as I'm seeing so many folks with the same problem. Trying to connect to the printer when there's a way of connecting to the wifi and vice versa makes no sense, even with a different frequency. At this point, after many hours of back and forth, this is not only a waste of time but a horrible product, and while I appreciate the hp response, the service is still pretty substandard. I feel like I'm better off just getting a new and different printer altogether, as I was hoping for something minimal for my shop, but this has been more complex than it should be.

No need to apologize -- DeskJet is an entry level printer.

Sub-standard service is never what we are going for -- that said, we do what we can.

Smiling.

This model, as far as I know, is typical of the general type -- it should work and yes, there are limitations.

Yes, this particular printer was and is limited to 2.4GHz.  There are a few of these, even today.

What?

This model was introduced back in 2016.  

Connecting a printer to a network when the printer lacks the ability to interact with you using a touchscreen Pinter Control Panel does mean you must rely on tools like EWS.

All the manufacturers sell decent products -- I hope you find the right product that will work in your shop and network.

If you can do so, perhaps look at a newer model (any brand).
