Deskjet 4158e not staying on network

[pgreen7436]

No matter what I do, the printer won't stay connected to the wireless network.  I have reserved the IP in the DHCP, set the port to not time out on the switch, set the config not to sleep but it just keeps disconnecting.  I want to return it but it's still under warranty and there isn't an option to return it.

Welcome back to the HP English Community --

True - Product Return is generally not part of the option list for HP Support in-Warranty repairs. 

Depending on the reason for a covered hardware issue, HP might replace, repair, or offer repairs at charge for the device.

We do not speak for HP Support --

If you think your device is failing due to a covered hardware defect, contact HP Support.

Reminders

• The standard hardware Warranty is not "nose-to-tail" coverage.  
• Software and other setup help is limited to a brief time period soon after purchase.

Starting on Page 19

The device manual states that wireless connection is supported for either 2.4GHz or 5GHz .

That said, should the printer not stay connected on 5GHz for any reason, connect the printer to a separately SSID named network for 2.4GHz.

True - A fixed, manual, static IP assignment can help stabilize a shaky connection.

There are additional factors -- some of these are not related directly to the printer itself.  For example, the router might be old, outdated, not completely or correctly configured.  The router might be placed too close (yes, this is a thing) or too far away.  Physical obstructions (walls, cabinets, other equipment) and interference plays a big part, too. 

Wireless is complicated -- it does not always "just work".

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A router that is weak, outdated, poorly located, or incorrectly configured can cause all sorts of odd network behavior issues.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

Examples – EWS Setup – IPv4

EWS > HP Document / How-to (original format)

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.

Example - standard EWS - IPv4
