HP Deskjet 2540 Unable to Connect to Wi-Fi

Ok, I'm sorry for not being able to help you.

Have a nice day as well,
Sincerely.

Oops. I didn't see your response because I didn't receive the notification and yet it’s been a while! I'm sorry. I did what was recommended in the link you sent me. I also uninstalled and reinstalled... it still doesn't work on Wi-Fi and yet the light is fixed.
Thank you for your help.

Hello Mélusine18,
Just a question, is this the driver you used when setting up the printer, DJ2540_188.exe?
Best regards.

Hello Gig29,
Yes, I just checked, it's indeed that driver. What I don't understand is that this issue has already happened to me; after doing various manipulations, sometimes it works again and the WIFI installation is fine, then a few days later, it stops working again :-(.
Thanks again

The link to the Page provided in response n°6 didn't help? Response n°6
Aside from the printer's wifi connection, is this wifi working correctly?
Best regards.

Good evening Gig29,
You have no reason to be disappointed. There are some computer inconsistencies and it's not your fault! ;-)
I find it very nice that you are trying to help me.
While wishing to install the driver you provided the link for, I just realized that it was installed on my PC on December 15, 2015. So.......
A thousand thanks.
I will still try one last time since my PC rested last night, you never know..... :-)
Best regards

Well, it's still impossible! I think my printer isn't even recognized by the network anymore... not surprisingly, given the number of manipulations I've done!
Computing is full of mysteries.... ;-)
Thanks again and have a good evening.

Good evening Mélusine18,
Indeed, when technology works well, we often don’t notice it too much, but on the day when everything doesn’t go as we want, it can be a hassle!
I’m still disappointed that I can’t help, staying stuck on failure isn’t really my thing!
Have a nice evening as well and maybe next time will be better!!!
Best regards.

I promise next time I will manage to have a fixable breakdown or a simpler problem to solve :-).
You had no obligations to achieve results anyway. You have already been very present, and it’s a success in the help you provide.
Good luck, and thank you again.

Good evening citro114,
You are probably right, but let's wait for Melusine 18's reaction to this post anyway!
From what I read in the previous exchanges, this printer installs without issues on her daughter's PC, which implies that the printer might not be to blame!
Let's wait.......
Have a good evening.
Best regards.

Hello to both of you.
It seems to me that there is indeed a compatibility issue between the printer and the PC. The problem is that I can't completely remove the installation program in order to reinstall it properly. There are always some remnants left. I had asked how to permanently delete it, but I didn't get any answers.
I had already encountered this Wi-Fi issue, and the WPS method had worked until a Windows update disrupted this fragile balance :-).
I'm not going to risk changing the card because I don't know how to do that. Messing around with the heart of a PC is not within my skill set. And taking it to a repair shop would be expensive given the labor costs. :-( with no certainty of results.
I'm going to try again with WPS; according to the help link that Citro114 sent me, it can sometimes be useful to do it several times.
Thank you for your help and have a good end of the night.

Hello, I had the same problem as you. I went to the control panel, printers and devices, printer properties, ports, and checked that it is indeed the printer's IP address that is set and not a WSD port.
Have a nice day

Great job on Oliver's last comment, it's working beautifully now, you just need to add a TCP/IP port by entering the printer's IP address and it works like a charm.

Make sure to deselect WSD, that stuff is really bad lol.
