Solved: HP 7520 loses wi-fi connection. What can I do? - HP Support Community

swcrutch · ‎11-19-2012

I have seen a lot of talk about HP products losing wireless connection. I am having the same problem with my 7520. Initial setup went perfect, but it started losing the connection when it went to sleep mode. Anyone have a solution??

A QUICK SOLUTION EXISTS ! ! !
On April 18, 2014 (page 11 of this thread) I posted a quick solution. My HP7520 printer has been working on Netgear 7550 router WIFI flawlessly ever since. I suggest reading that post.
From long experience with HP I have found that they have great hardware but their software has always been dismal. The ultimate "fix" would be for HP to remedy their software failure that allows my fix to work.
A single "tweak" in the router wifi security settings does the trick. All the rest of the setting changes other folks have suggested are short lived (about an hour in most cases) then they don't get reconnected unless they restart everything. That makes sense because of what's happening.
The single "tweak" setting should logically point the HP programmers to where in the firmware the problem exists. Are they listening? And, It really doesn't matter about all the other printer and router settings. All mine are back to factory defaults and it all still works just fine.
Go do some BBQ and quit wasting your time on this issue.

A lot of these problems are router caused. What router are you using? What operating system?

Does the printer have a strong wireless signal?

Netgear router - Strong wireless signal (in the same room) - Windows 7

I have 3 other laptops, (2 dells and 1 toshiba) and an Xbox and a Wii. - All connected to the router without a problem.

Any time I want to print I have to turn off/on the 7520 printer so it re-establishes connection. Lasts for about 5-10 mins and then loses it the connection.

Set the printer to a static IP outside the range of the DHCP in the router. Use a fixed channel, never 'auto'. Use WPA2-AES for yhour encryption. Now try.

Already using a staic ip address and WPA2 AES. i will try the fixed channel. Let you know - thanks

Specifically, change the 2.4GHz channel to 11.

Again - changed from automatic to channel 11

Lost connection after 10 mins

It's on a static IP address and WPA2-AES

Still won't stay connected - any other advise?

Hummm, ok, try channel 1 to see if thats better.

PrintDoc · ‎11-20-2012

Try changing the encryption to WPA or none at all for testing purposes.
