Mac OS X 10.7 drops network connection to Officejet J6480

Mac OS X 10.7 drops network connection to Officejet J6480. I can re-establish by power cycling the printer.
Other computers cannot connect to the printer even though they are on the same network.

What router are you using? Are other computers Macs as well? What operating system are they using?

Time Capsule keeps dropping network connection

I recently got a Time Capsule to replace a dead external drive and my AirPort Express. I was able to set up the Time Capsule as a router with little trouble but using it as a Time Machine backup drive is driving me crazy. Each time I start a backup the Time Capsule eventually drops my network connection before it can finish. I have about 200GB on my internal drive. Could this be too much to transfer over Wi-Fi?
I never experienced a dropped network connection when I was using the AirPort Express and my second Mac (a G4 iMac) never looses the connection. Any ideas what could be going on here?

Very interesting. Been working this problem from every angle. Noticed two kickers.
1) Transmission would refresh to fast when opening and closing menu bar airport icon.
2) Transmission never fades when running iStumbler which is continuously interrogating Time Capsule.
MacPro software seems to be forgetting that it is hooked up and drops out. It is a software thing.
I am starting iStumbler for each session automatically now and am having no drop outs. It is keeping Time Capsules attention. It is not required for all computers in the house but certainly is for the MacPro from which I control everything.
Amazing. Can one of the FanBoys bring this to the attention of the right person at Apple? Also, I need work and have many stories of trouble shooting successes. Tell them to hire me. It would save you guys a lot of time.

Windows 8.1 Lock Screen drops network connectivity when screen locked using Win+L

Hi!
I was sent here from Microsoft Community forum. The question is:
Since Windows NT 4.0 I'm using Lock Screen to prevent people from accessing my computer when I'm leaving my room. First I was using CTRL+ALT+DEL / Lock Screen, then switched to Win+L keyboard shortcut when it was first introduced.
Everything was fine until I switched to Windows 8.1 computer (Sony Vaio Duo 13 with Broadcom wireless network controller). This machine is 8.1, not 8.0 upgraded to 8.1.
My problem is that when I hit Win+L combo the Lock Screen (with clock etc.) is displayed. Then, despite I have configured not to turn off display, the screen goes blank (after 30 seconds since lock) and network connectivity is cut off from desktop
apps (I suspect the system goes into Active Standby mode, because Modern UI apps like Tune-In radio keep working fine).
100% repeatable scenarios:
## Scenario 1 ##
1) Log in
2) Open desktop app that uses network connectivity. Outlook 2013 from Office365 subscription
3) Check that it has connected
4) Lock screen (Win+L)
5) Wait for 30 seconds (first incorrectly posted as few minutes) as screen goes black
6) Unlock screen (using password)
7) In right corner of Outlook app you will see "Unable to connect with Exchange server" and few seconds later it will reconnect sucessfuly
## Scenario 2 - the more annoying ##
1) Log in to Win 8.1 computer
2) Connect to it using SMB (in my case I wanted to transfer 30 GB of files from local hard drive C: to server) \\COMPUTER-NAME\c$ from Windows Server 2012 R2
3) Start copying files from computer to server
4) Lock the screen on computer
5) As soon as screen goes black server displays message "Lost connection to the resource. Try again?"
6) Unlock screen on the computer
7) Click "Try again" and it will continue copying files
My power settings are set to go into stand by after 5 hours and if I not lock the screen it doesn't go to sleep before 5 hours.
When I lock the screen using Win+L it goes into (probably Active) Standby mode.
Is there any way to prevent it from going to Active Standby when locking screen? I need the screen lock for security reasons but I don't want it to drop my network connectivity on remote desktops, file transfers and other desktop activities before 5 hour
timeout.
This issue is not related to more or less known wireless network connectivity problem that happens to many Intel Haswell computers. Mine doesn't exhibit those problems. I can easly push 100 - 200 GB of wireless data without network drops.

Same issue here using Surface 3 Pro with either internal WLAN or MS USB LAN Adapter. I'm frequently used to keep open connections over SSH to some servers. On switching to lock screen explicitly by pressing Win+L or implicitly due to idle timeout all
connections to servers are lost. In addition, I don't get any notifications on incoming Skype messages (using Skype for desktop) when lock screen is active.
Neither NIC is showing "Power Management Tab" according to step 5 of instructions above.
Additionally observing USB LAN NIC seems to be kept active after activating lock screen, but traffic stops (according to its flashing light) when lock screen is switching off display. Blanking display doesn't seem to be adjustable in System Settings (Energy
Options accessed through Win+X).
Find attached log file of powercfg -energy -duration 300 ...
Log file is in German. It basically claims unset timeouts for deactivating display while running attached to power supply though lock screen is turning off displays within 1-2 minutes.

E6 Belle dropping network connection

HI, I got my E6 just before Belle came out and upgraded after waiting a month or so for any issues to become apparent.
Every now and then the network connection lines become broken and I am no longer able to access the internet. I spent an hour on the phone with network provider (T-mobile in UK), switched the sim into my old phone and it worked fine. Restarted the phone a few times. I played with the network settings and changing it from 'dual mode' to 3g or to GSM got it back up and running. The problem happened again several times and I left it on GSM and didn't have any problems for a while, but now it's happening again and more often.
It happens regardless of location and at no apparent specific intervals. Assistance would be great, I've been loving the phone and planning to have it for a long time, but I use it for work and need to get email!

VZ can only "look" as far as their own equipment, meaning they can see whether you are correctly provisioned, supplied, drawing bandwidth, etc.  They cannot see your end of the equipment assembly, of course.
What it sounds like is that one or more pieces of gear and equipment are not functioning correctly all of the time. This is often due to poor or faulty connections in the cables, intermittent faults and gaps, etc.   Therefore the first course of action is to check and reset all cables (yes, it's likely that you've already done this, but just for drill, do it once again!).
Having done that, you should devise a test that allows you to insert one piece of gear into the network at a time. Start with the router and only a single computer, for example. Wired is probably best at first to see what happens (yes, these tests take time, but there's no way around it). If that assembly works consistently, try a wireless connection next.  Record the results.
Next I would add back a single STB (of any type) and see if the TV system is OK. Finally I would add back the remaining devices one at a time and observe the results. Somewhere along the way you will encounter the offender, but if you do not and if the gear now functions per specification, your time won't have been wasted. Good luck.

XP Mode in Windows7 Professional Drops Network connectivity

Ok - I've seen and followed several (5+) discussions on this problem dating back 4 years through Vista, but no one seems to have posted a definitive question. I've been rolling out Windows 7 for over a year now and have been following the same procedure
and installing the same apps to the same configuration without issues until this week, I now have 2 boxes doing the same behaviour.
Environment:
Workstation is a PowerSpec B634 with Intel motherboard, using onboard RealTec NIC. Windows 7 Professional, with Microsoft's Virtual XP vhd. They are connected only via the ethernet NIC (wireless is disabled) on a 1GB connection. I've moved
the port on the switch they've been connected to and switched both the patch cable at the rack and the ethernet cable at the workstation. And, as I've said I'm seeing this behaviour on 2 separate boxes.
Behaviour:
Unit boots flawlessly and I've not seen any connection issues on the Windows7 side of the world (i.e. Outlook isn't reporting disconnects from Exchange and the NIC isn't reporting loss of connection.) However, in the virtual XP side I can launch the virtual
XP, and then start my database application. It finds the database network share (mapped through the virtual xp as a drive letter to "//tsclient/drive" referencing a share on the host Windows7 machine. The application runs great up to
10 minutes at which point the connection to the network drops as the database client loses all pointers to it's tables and references and crashes. If I start a remote desktop session from inside the vitual XP it also will run fine for a while then report
the conenction has been broken. At no time does the NIC icon in the virtual XP system tray report loss of network connection.
I have turned off all power-saving settings in BIOS, Win7, and as much as I could find in virtual XP - - I'm really at a loss here, especially as I have 15 other machines of very similar specs and identical software installations working just fine, oh, and
yes, I'm running SP1 and have downloaded all available patches.
Hints tips suggestions and/or more questions all very much appreciated.

Thaks for the suggestions - as noted in my original post:
1) all power management for the NICs (which are integrated on the Intel Motherboard) have been switched off in BIOS, Power Management in both the Win7 host and XP virtual environment, and in Device Manager specific to the NIC I've switched of any power management
options to force them to stay on at full speed/power at all times
2) I have had this problem now with the computers plugged in to two different "patch to outlet" locations in the office (i.e. different in-wall wiring), plus have used two different wall to PC ethernet cables (which I have also pin verified with a fluke
cable tester) and have used different patch bay to switch cables and have not only switched ports on the switch but have switched to a completely different switch.
With those considerations taken into account I am continuing to see the issue. The connectivity drop is occurring pretty regularly between 6 and 10 minutes of operation.
3) sorry, yes, NICs are same model as both towers have same Intel motherboard.

Apple TV 3 drops network connection when it goes to sleep

I updated my Apple TV 3 to software version 7.0 (based on iOS 8) and now every time it goes to sleep it shuts down the network connection. To wake it up, I either need to use the remote or use an iOS 8 device that supports handoff. At least I think it does since my iPhone 5s can wake it up, but my iPad 2 cannot. I believe the Apple TV is now using Bluetooth for connections. This basically means Airplay with older devices won't work without first waking the Apple TV. I'm not sure the point of the change since I'm using Ethernet, not Wifi, so there's no reason to "power down".
on a side note, sometimes the iPhone 5s can't wake the Apple TV either. It usually wakes up when I open the control panel, but not always. It goes back to sleep when I close the control panel.
Ia there any setting to make it work the way it used to?

the WIFI does not drop when my appletv goes to sleep.
my iphone can still see the appletv (via the airplay icon) when it is asleep.
All you are seeing is the last known Wifi state in iTunes (and similar app in iPhone, iPod, iPad). The AppleTV however has powered down "something" in its own mechanism to conserve power.
For the Apple TV to use such low watts in operation, its got to be powering down something.
I have seen this behaviour before in other devices that try to power down Wifi in a sleep state. It is not connected but it thinks it is. I'm not an expert in Wifi technology so won't state what is happening behind the scenes but do know that re-starting/re-powering up the devices will cause the wifi connections to be re-established.
I would try this but don't have access to my ATV at the moment. Turn off encryption and see if the problem persists. My gut tells me that the WPA/WEP encryption has lost itself in the low power state.
I suspect that 10/100/Gig RJ45 ethernet connections are not affected.

Airport Extreme dropping network connection

Hi all,
I have had my iMac and Airport Extreme for about 6 months. Within the past month, each time my computer either hibernates or starts up after shutting down, I have to physically unplug my Airport Extreme for the Internet connection to work again. I have tried to update the software and also tried to reestablish the network connection using the Network Preferences and System Preferences yet nothing has worked so far. Any help would be great! Thanks,

I believe it has something to do with securing the network as I'm now running an unsecured network and it not only stays up but it also seems a bit faster. I even ran the Airport Utility via ethernet and got it to "almost" configure but for some reason the setting never got implemented but at least I have internet access in my entire house. I thought it might be interference with some part of the house but it is indeed due to the latest firmware update for the AEB. Which I now call AE"BS". I tried my older Airport Express but I also couldn't get it to configure to now I'm not even sure if its firmware on the AEB or the Airport Utility that is messed up. Going tethered is not an option as I don't want to hunker down in a closet! Go unsecured and it might fix a lot of the issues we are seeing.

Randomly Dropped Network Connections WRT54GR

Two wireless notebooks running Vista, two wired desktops running Win2k Pro. Router is used for internet connection and networking. (Assigned IP addresses) All devices maintain steady internet connection. So far so good.
But network connection is not steady. If I reset the router by powering off and on, everything is fine for a while, all computers see each other. But within a random space of time they stop seeing each other consistently. I then have to do a power off/on.
New to wireless and home networking. Is this just to be expected? Any ideas of how to fix the problem?
Thanks!

I think you should disable all the firewalls on these computer and reduce the MTU on the router to 1365, beacon interval to 50 and RTS and Fragmentation threshold by 40 each.

Is there any simple way I can find out whether my router or my mac air is responsible for dropping internet connection constantly? Often when I do the network diagnostic, the wifi light is green, but isp internet and server are either amber or red.

This is driving me crazy. The router (it came with the apartment) is a Fritz!Box fon Wlan 7240. I would be willing to buy an new airport if that would fix it. But in this country (Germany) you probably can't give things back.

This is not an alternative to Susan Howard's diagnostic questions, only an atempt to collect more data about your situation.
Do you have the instruction manual for your router? I ask because at some point it might be a good idea to reset the router. Turning it off for about 15 seconds then turning it back on helps sometimes. The more basic procedure (this is with my router) is to push the reset. But that would mean you have to re-configure the router with password etc. from scratch.

I have a wireless LAN at home that is shared with 3 macs and a PC. It seems like the macs disconnect from the network after a while. I then have to reenter my network password, etc. Any ideas what causes this? Networking is greek to me.

Hi 3 macs-
A program that downloads file, mainly movies, explained here: BitTorrent
Those programs tend to hog a lot of bandwidth.
Is this something new that has happened or have you had the problem for a while?

Drops network

our iPad 2 drops network from home. We have to reset network and password whenever we turn on. Our IPad 1 works fine-No drops

FYI. Here is my setup:
Dual 2.5 G5 (10.4.5)
12" 1.5 Powerbook (10.4.5) via airport
Dell 3.0 P4
Running into a Belkin router and then into my Cablevision modem.
The modem is connected and online, and the Dell makes a connection (hate to say the PC works better
But both macs drop network connections. They are all connected to the router, and in-turn the router is making an IP connection via DHCP. Cablevision was able to ping the router from their end, and even see the three machines connected to it. But macs time out all network connections.
Hard-wiring the macs to the modem produces a unique IP number via DHCP. The modem continues to say everything is OK, but the macs fail to connect. Rebooting produces a new IP address, but still does nothing, whereas PC continues to connect fine every time.
ALL of this occurred after upgrading on Monday night to 10.4.5, so I have to agree that this version is doing something buggy to the network connection.
I'd hate to have to switch to the PC for work until 10.4.6, but if Apple doesn't get this issue sorted ASAP, then that is my only recourse for work.
Any suggestions?

Bootcamp Windows 7 Wireless Network Connection: No Valid IP Configuration

I just bought a new 13" MBP and have installed Windows 7 Ultimate via Bootcamp 5.0. I installed the Windows Support Software that I had previously downloaded via Bootcamp Assistant on Mac OS. Although the Wireless Network Connection asked for my network key and connects to the network, I cannot access the internet. The troubleshooter find this problem: "Wireless Network Connection" doesn't have valid IP configuration. I am using my old Dell computer and it is connecting to the wireless properly and my MBP can connect on Mac OS, so I don't think it's a router issue. Here are the things I have tried so far to resolve this issue, but none have worked:
Uninstalling the Broadcom Network Adapter driver, restarting the computer, and reinstalling
Repairing the Windows Support Software with the Bootcamp 5.0.5033 Support Software Update downloaded from www.apple.com
Uninstalling the Broadcom Network Adapter driver, restarting the computer, and reinstalling the driver from Bootcamp 5.0.5033

Please help!

Did you find a solution for this? I have exaclty the same problem.
But I could temporarily solve it by setting an IP, gateway, dns etc manually. But that will only work in my current wifi-network.
I can't even get internet sharing from my iphone

Network connection good, explorer good, but no safari or mail

First post and could really use some help. I have been using a belking pre N wireless router to connect to my comcast cable internet account. The network is set up using my PC and I have an airport express card in my Imac. Everything was working fine for quite a while but about 6 months ago I lost the ability to connect to the internet from my mac. I get a strong network connection on the mac, I can get to the internet fine from my PC, but cannot get a connection through Safari or mail. Strange thing is, right now I'm accessing the internet wirelessly through my mac using an old version of Internet explorer. I've tried resetting/restarting all of my components but to no avail. Does anyone have any idea on what's going on? Thanks in advance for any help.

It's possible that the issue is with your ISP. Some folks have reported that they needed to change the MTU value (1500 to 1492) of their connection in order to access certain websites or their email.
Change MTU using Terminal
To change the MTU value, using Terminal, check out this Apple article: http://docs.info.apple.com/article.html?artnum=303192
For a "permanent" solution, I suggest using Cocktail.

Connecting HP Officejet 6100 to wireless network with OSX 10.9.5

Running OSX 10.9.5.
I'm trying to connect HP Officejet 6100 to wireless network without HP software since the software claims it is not compatable with my OS.
The printer works fine when connected via USB.

Hi @dj2thew,
Thank you for visiting the HP Support Forums! I see you are trying to add your HP Officejet 6100 to your Mac running the Mavericks 10.9.5 Operating system.
Because you are using the Mavericks OS X you must install the printer using the Apple Updates. Please click on the link below, this document explains how to install the print driver on a Mac for a USB or a network connection. The OS X v10.9 Mavericks driver for your printer is available through Apple Software Update (ASU). Additionally, you can perform basic print jobs using AirPrint without installing a driver.

Once you have installed the OJ 6100, you may notice the features you once had are limited or there are workarounds, for scanning with or without HP Software see below:
How to Scan: OS X v10.9
I hope this helps!
Thanks again,
