Frequency issue smart hub 2

TJcolt — Wed, 07 Jun 2023 14:04:41 GMT

Hi,

I can't connect to printer due to frequency issue, HP printer using 2.4 Ghz. This should be a dual broadband frequency smart hub right? Any ideas what to do? I tried the rescan with no joy.

Hi @TJcolt Try turning off the 5 GHz band, connect the printer and then turn it back on. In situations like this, I find it helps to fix the channel rather than using smart channels.

Thanks. Done this. Still having the issue. It's connected but not connected. And not across devices.

Reset the printer back to factory setting and ensure SH2 5GHZ wifi is turned off

Then try and set up your wireless connection from start and printer should connect without a problem. Once connected then turn 5ghz back on and printer should be fine

Are you sure the printer is set as a network printer rather than trying to connect to it in ad-hoc mode. If in ad-hoc mode, your devices need to be operating on the same band as the printer, 2.4Ghz. If the device trying to print is connected to the hub at 5Ghz you won't be able to print directly to the printer in ad-hoc mode. Turning off the 5Ghz forces your device onto the 2.4Ghz band.

Still not finding network. I might contact BT. Broadband is working fine.

You might as well contact the man in the moon, BT won't be able to help.

Has the printer worked previously and stopped working or has it never worked?

The printer is fine and worked on all previous networks.

BT are telling me to turn off 5.0 Ghz and reboot hub.

Did you factory reset the printer before trying to connect?

Yes. Unplugged. Although BT are now saying there's a network problem and fix by openreach. Although I can't see how that fixes device connectivity.

Unplugging is NOT factory resetting.

BT are talking nonsense, you don't need an internet connection to print.

*I've a Smart-Tank 550 Plus, and thanks to those wonderful people at HP, at one point you did need an internet connection in order to be able to print to it - as could any idiot on the web who could guess the formulaically generated email HP assigned to the printer (no password required)!

So question to our OP, what is the printer model?

You need an internet connection or ethernet.

The issue is no devices can connect, the printer keeps connecting then going into sleep mode. 2 hours set as default.

Openreach are now looking into it and fixing. 99% sure it's a network issue.

To print wireless you do

The laptop is saying connected and the printer is connected to the network. So either it's a frequency issue or something else I can't think of. Keeps tripping into asleep mode.

You do not need an internet connection to print. WiFi within your LAN is totally independent of an internet connection.

Are you sure you haven't got a faulty hub?

Did you factory reset the printer?

At least we now know this is a printer that doesn't require internet. However, one of the "features" of some modern HP printers is that they simply "auto off" after 2 hours. There is no fix for this and no setting you can change to prevent it, it's a feature 😭

@licquorice there are some really questionable features on some HP printers!

*I can supply a screen shot if really necessary!

Ok, it would appear HP+ is an optional add-on for HP printers and once enabled requires an internet connection.

Why on earth anybody would want to limit themselves to having to have an internet connection in order to print is beyond my comprehension.

Instant ink. You can replace cartridges and print as normal if preferred.

All devices need to be on same network as far as I'm aware.

That's funny but I thought the SH2 didn't separate the two bands and therefore one could not turn of the 5Ghz band.
