HP 7520 loses wi-fi connection. What can I do?

It would be great if the solution laid out "half way through this thread" actually solved anything, but it didn't for me, or as it appears, at least a few other people.  Even if it did actually solve the problem, it seems to me a rather stupid idea to have a printer that people are expected to send jobs to purposely shut down its network connection at a set interval in order to save power.  It's an idiotic "feature".

In an ironic twist, I received a "lost connection with printer" message whlie I was typing this note.

HP - will you please read your own forums and fix your network stability for this printer?

Thank you.

I've had a 7520 printer for several months now on my wireless network. Sometimes I can print just fine from my laptop; sometimes the printer disconnects itself from the network at random, then reconnects at random sometime later. Spent 2 hours on the phone with tech support yesterday; the guy said his supervisor would call me back in 2-3 hours - still waiting. Ugh.

The wireless signal in my office space is not ideal, so I use a Linksys Powerline (PWL400) adapter, in conjuntion with my Linksys E4200 router. The first tech determined that my problem had something to do with this. Sometimes my printer will be on the network, but not recognized by my computer. Other times the printer will be offline altogether. With the Powerline adapter on, we could not access the IP address printer page. When I unplug the powerline adapter. the page becomes available. Leaving the Powerline adapter unplugged is really not an option, as internet speeds are unbearably slow. 

How can I get my printer back online with my computer and still use the Powerline adapter?

Thanks for any help!

It has been said over and over again, the problem is not our printers but the software that they use.   The problem is HP's trouble and I wish they would come up with a fix.    Too many people are having the same issue and nothing is being done.   If you get an answer that actually works from HP, please let us know.   Good luck pkrahmer

It's been one frustrating year for me dealing with HP and their printers. The first one I bought had a paper pickup issue which they tried telling me was software related. After haggling down to the end of the wire as the warranty neared expiration, they finally sent me a new Photosmart 6520 with the same network connectivity issue described here. Another 3 months of their "expert technical support" phone calls, one hour each time, still no resolve. With both issues, I scoured the web for resolve and tried every troubleshooting step I could find. I finally brought my problem back to the web, but this time in an article describing my frustrations with HP in a weekly consumer newsletter I write. And I sent a link to HP. Within 10 minutes, my phone was ringing. Someone in their elevated customer service group out of Toronto wanted to hear my problem first hand. And she spoke English.

We went through all the troubleshooting steps one more time, as expected with no resolve. She admitted that their tech group only had access to the same documents we could access online. Nobody could offer anything of further assistance. But she would replace the printer with a 7520 in case it was a problem with the NIC. And I'm having the same problem once again. I held hope when I saw sleep mode could be the culprit so followed the posters steps. Within minutes, connection lost once again. So it didn't help this angry customer. Thanks for at least providing a place where we can share our misery. I'll stay tuned in case someone stumbles on something HP won't admit.

I bought a 7250 a couple of weeks ago and am having the same problems. I've tried most of the things suggested here with no luck. It looks like the only real solution would be for HP to sort it out. Should I wait for HP to fix this or should I return it to the shop and get something else?

I just tried this and after trying everything else (including static IP and even direct WIFI print server, which also timed out until power was toggled) I was convinced there was a sleep mode in there somewhere! Thank goodness i kept reading until I found your fix! Time will tell. by the way, as a note to anyone doing this, no you cannot simply press and hold the down arrow key and let it quickly go from 899 seconds to 0! You have to click it 899 times so be careful to click OK before clicking that X! This should be the very FIRST answer people see!

Speaking as a disabled person for whom this printer worked great for about 2 months before this cropped up, we all know it's a hardware failure but If resetting the sleep counter to zero causes mine to re-engage after a minute or two it would still be an immense improvement over having to manually power toggle it! You are correct in that HP should fix this issue. Even when it clearly isn't working the 7520 will report that it's connected to your network just fine!

For me all of it started when our isp changed our modem.  I worked with them to get back the same model of modem we had before and now it works fine.  Hasn't dropped the connection even once in over a month or two.  I don't know if it was a setting in the modem that was causing a problem but we could not figure it out so they just gave me the old model which worked.  None of the other suggestions worked for me.

PS

Mine still lost connection after about fifteen minutes requiring a power toggle even after setting the sleep mode time to 0. Nice try that should have worked but in my case didn't after all! Definitely a hardware or hardwired in firmware failure. I'm betting even hardwiring this printer to the router and not using wifi at all won't fix this!

I too have had ths printer for only a few weeks with the sam problems.  I tried everything in this posting but still th same problem.  Then I read closer to the end of the post and saw that multicasting should be turned on on the router.  I am not a tech person and did not know this.  I turned it on about 24 hours ago and as of now have not had a loss of wi-fi.  I hope this continues and has fixed the problem.  Thank you to all of you who have spent many many hours on the phone with HP tech support
