HT1365 Mac wireless connection dropping

My iMac is in my home office connecting wirelessly to my network router in the same room. The computer drops connectivity to the network and therefore the internet often. I have searched knowledge base and not found a solution to my problem. Has anyone had a similar problem that has a fix?

I would suspect interference:

Wireless connection drops out for no reason

I have a macbook with 10.4.11 update. I had my macbook since october last year and had no problems. About two months ago now i have this problem were my wireless connection drops for no reason, my modem/router shows everything is working normal with its lights on the front panel.
My setup is, motorola sbg900 on a cable 80000mbps wireless network, firewall off on my modem, firewall on on my mac (its always been on), Playstation 3(wireless), PC(wireless, but is switched off), another pc which is wireless and also off, nintendo wii off as well, and a baby monitor.
I have a feeling its nothing to do with my setup(except for maybe port forwarding) but am wondering if it is an update issue bug that needs to be fixed(thats what im hoping).
One other thing, when my connection drops in the menu bar and i select it to see which networks are availale, my network motorola8566 is not visible, another 'motorola9522' and 'wireless' network is?My prefered networks dont list any of these in system preferences. Then all of a sudden those other networks dissapear, my network is reshown and i can select it no propblems. What gives? Any help would be great, thanx in advandce

I have the same issue with my wireless connection being dropped. I have the most recent version of leopard 10.5.2 . The other macbook in this household also has 10.5.2 and has no problems with dropped connections. I tried resetting the pram which helped at first until I used my macbook on the battery alone the problem started to reoccur. Help?!?

Wireless connection drops at random

Hi,
I have a 27" late 2011 iMAC. Since I updated to Lion my wireless connection drops at random. The wireless symbol shows that I am connected, but i cannot use the internet.
The sollution at that time is that I turn off wireless, and than turn it on again. This solves the problem, but only temporarely. Since I also own a NAS for TimeMachine backups, the dropping of the connection is annoying because the backups fail most of the time.
What is causing this problem. I have 2 windows PC's and the connection stays. Router has latest firmware (fritzbox 7340), and my mac is up to date.
Please help.
Thanx in advance.

Hi,
try to change the WiFi channel on your fritzbox, sometimes it works better on higher channels 11, 12, 13 especially if there are Telekom routers in your neibourhood. Make sure to use the latest Firmware for your Fritz!Box, the actually had a few issues in this area a few months ago. If this still does not help, only activate the 2,4 Ghz Bandwidth on the Firtz!Box and deactivate de 5 Ghz option.
I hope that this will solve your issue.
Cheers

10.5.2 failed to fix wireless connection dropping problem

10.5.2 did not fix wireless connection dropping problem. I lose wireless connection whenever my MBP restarts or wake up from sleep in the building where I am and have to retype password about 10 times a day. I had not had this problem when I used Tiger. Everyone who has upgraded to Leopard or has it installed on their Mac is experiencing the same problem. Is there any solution or trick to resolve this problem? Thank you.

Amularya,
Please read the post I made in this thread earlier. No less than a dozen solutions are offered in the link I provided for wireless issues. Troubleshooting wireless issues requires individual attention because of the plethora of issues which can't be tested for. So please start a new topic thread here:
http://discussions.apple.com/forum.jspa?forumID=1225&start=0
So you can get a wider audience, and won't confuse the original poster with solutions that don't apply to them.
There literally hundreds of different WiFi adapters.
Dozens of different virus and firewall combinations.
Possibilities for damaged WiFi cards and routers, as well as routers whose firmware is not to spec with the latest wireless standard.
To top it off, bad RAM, hard disk being too full, and bad preference, cache or or logfiles can make various aspects of the operating system misbehave, and/or even the directory leading to those files.
Until each person starts their own thread looking for solution individually, chances are they won't find one. Yes, 10.5.2 addresses WiFi for some people. Obviously it doesn't for everyone. The point is, there are some people, like myself who have never had a WiFi issue either with Intel or PowerPC Macs that they couldn't resolve without a little bit of troubleshooting. I'm happy to help you walk through it, but only if you start your own thread asking for help.

Wireless connection drops every day -- iTunes 8.02 the problem??

Hello! Our iMac is connected to the internet via Airport, and we have rarely had problems with the connection. For the last two weeks, when I get on the iMac for the first time that day, I have to reconnect to the wireless network through the Airport Setup Assistant every single time. I've tried resetting our cable modem and Airport -- no effect on the problem. I've tried going into sleep mode without logging off to see if that might help -- nope. I've tried repairing permissions in the off-chance that that might help -- no again.
In something that seems more than just a coincidence, we updated our iTunes to 8.02 about two weeks ago, and that's when this problem began happening. I am especially suspicious that there's a link because we did not update iTunes on our Macbook and it has no problem whatsoever staying connected to the exact same wireless network.
Two questions, then:
-- Is the iTunes 8.02 update the problem?
-- If so, how do I go back to iTunes 7.7?
Thanks!

Hi, I'm new to iTunes and apple, but this is happening to me too! I've got iTunes 8 and whenever I run it, my wireless connection drops (disables itself) and cannot be restarted without rebooting the machine. Did you manage to find an answer?

Wireless connection drops after time. Please assist.

Hi
My problem is that my wireless connection drops every 5-15 minutes.
I don't know all the relevant info to give. If there's something I can post that will help let me know and I'll reply.
I've used netcfg to configure my network. I have a Canyon CN-WF511 wireless card.
I load the following 3 modules in my rc.conf; rt2500pci rt2x00lib rt2x00pci. I think those are the only ones pertaining to my network card.
When it drops I just netcfg -a then netcfg default (profile name) and it works for another few minutes.
Below is my network profile.
CONNECTION="wireless"
INTERFACE=wlan0
#IP="dhcp"
#DHCP_TIMEOUT=20
IP="static"
IFOPTS="192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
GATEWAY=192.168.0.1
#DOMAIN=localdomain
#DNS1=192.168.0.1
ESSID=default
SECURITY=none
SCAN="YES"
TIMEOUT=15

The easiest solution might be to setup NetCfg somehow with your wifi card and access point. Have you tried that? Can you find your card's chipset on the wiki?(chances are that your particular chipset will need a firmware put into /lib/firmware. Again that's found on the wiki on the NetCfg or Wifi page, I forget which sorry.) Those are two places where I'd look for good information.
By the way, your rc.conf is way out of date. You should look at updating it by using the recent rc.conf.pacnew file that you'll find in the /etc directory.

Wireless connections drops after AirPort Extreme 2007-001 Update

Hello, I am getting a lot of wireless connection drops since I installed the AirPort Extreme 2007-001 Update. Anyone has similar issue? Any fix?

Well, I was conneting to the University's wireless server (which is maintained and huge) flawlessly prior to the update. My friend has a macbook pro and didn't apply the update and he has no problem. I installed the update and since then I'm having a hard time connecting to ANY wireless server/router.
I came across the following, looks like a lot of other persons are having the same issue:

http://www.macfixit.com/article.php?story=20070126190822382
Looks like my solution would be to perform an Archive & Install and to not reinstall the AE 2007-001 update.

Wireless connection drops after bout 5 min - HP all in one C6180

Hi!
I'm having problem with my all in one product - HP all in one C6180. The wireless network connection drops, and the printer becomes unreachable from both web-interface and printjobs/scanningjobs etc...
This problem has existed since I bought this machine..
I've tried several different setups when it comes to WEP/WPA/WPA2 etc..and also different channels on the wireless, but still same problem exist. The printer works perfect for about 5 min, but then drops the connection it seems like. I'm having about 5-6 devices connected to my wireless router (Draytek VGI 2910), and all seems to work perfect together except the C6180.
At this moment I'm running WPA2 for security on my network. I've tested the software both on Win/ Mac, and currently running the Mac-version.
Is there any firmware-update out that could solve my problem, or how else should I manage it to work properly?
Thanks for any help!

There does not appear to be any firmware update on this page. It could be a router issue.
Let's set a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, set a high IP address, like .250
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (ends with .1) for the gateway and first DNS. Leave the second one blank.
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

Wireless connection drops sporadically

I have a Linksys router that wirelessly connects my iBook G4 and my roommate's G4 tower. It also connects to my G4 tower, but that's a wired connection.
I used to use a Linksys Wireless-B (2.4 ghz 802.11b), but it broke and now I have a Wireless-G. But, both router's gave me the exact same problem. Sporadically, the wireless connection just drops for about 5 or 6 seconds. I haven't seen any pattern, as far as how often it occurs, and I can't for the life of me figure out why it's happening.
I was told that it might be interference, so I changed the channel to 11, and everything seemed to work great for about 3 or 4 days. Then, it started happening again. I switched to channel 1, and that didn't help. I switched to a different channel, again no help. Now I'm back on 11, and it's still dropping off sporadically.
I'm pretty sure this never happens to the wired connection, but I don't use that computer very often. Any suggestions? This has been going on for months, and I don't have the faintest idea how to fix it!

I am with you Joel.
I recently purchased a G5 iMac with built-in AirPort and I am having the same problem. Yes I have a cordless phone in the house and it could be interfering, but I also have a Windows laptop (I know, I know...Booo) which is on the same wireless network and it has no trouble communicating. I have tried different channels on my router and the Mac works for awhile, but then the connection starts and stops.
I was hoping the latest firmware updates for AirPort would have one for the Extreme card, but no go.
I haven't yet sat the wireless router right next to the computer to see if that cures the "interference", but that is the next step in my troubleshooting. If the pulsing internet stops pulsating and I get a constant connection I will believe all the interference rhetoric, but until then I am sceptical.
Note: I also tried the "Interference Robustness" setting and that just made it worse. There doesn't seem to be much help on that setting so I have abandoned it. Any insight from anyone on that setting?

Frequent wireless connection drops: how to re-connect?

My wireless connection has become quite unreliable of late, and I'm not sure how to diagnose/fix the problem. Configuration:
MacBook Pro4,1
Intel Core2 Duo
Max OS X 10.6.6
When the connection drops, I first try to "Turn Airport On" with the menu bar, but this has no effect.
Using Network Preferences to "Turn Aiport On" also has no effect.
Turning to the command line, I try 'ifconfig -a', and get:
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
status: inactive
I tried bouncing the en1 interface using:
ifconfig en1 down
ifconfig en1 up
But the status stays inactive. Any thoughts on what I should try? A reboot always
resets things and gets them working again, but it's incredibly annoying to have to
reboot when in the middle of something.

It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease".
6) In the folder /Library/Preferences ( not <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
They may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

Hp office jet 6700 (Mac)-wireless connection keeps failing...

Hi-I am hoping that someone has a solution for this. We have an HP Officejet 6700 that has worked flawlessly till last week. The wireless signal keeps dropping. I think that is the issue because if I go into Setup on the printer itself and go to Network and start all over with finding my router, it works fine. For one print job. Then if I have something something else to print I have to go through that whole setup routine again.
If I just go to Print it says locating printer and then it says that the printer is not connected. What is going on?? Very frustrated. I tried uninstalling and reinstalling the driver (I downloaded the driver from the HP website). That didn't fix it. I saw that there was a firmware update but couldn't install it even though I plugged my laptop into the printer with a USB cord.
Something is going on that I don't have a clue in how to fix it. I really appreciate any help. Thank you, Judy

Wireless connection drops on 1/2 of computers on network

I have an Apple Airport Extreme N Router setup to feed my NAS wirelessly to all computers on my network. Some computers on the network can sign in wirelessly (Via TP-Link TEWDN3200 USB Adaptor) and connect to the NAS. The other half drop connections all the time and cannot connect to the NAS in any way using the TP-Link USB adaptor or the PCI-e adaptor. (Via Webserver or mapped network drives) Computers which are wired directly to the router can access the NAS without any problems.
Some more facts:
- All computers (with and without the problem) are running Windows XP PRO 32 bit SP3
- Some computers are using a TP-Link TL-WDN4800 with latest drivers
- All computers are connecting via the Wireless Zero-config service
- In the 'status' window on the wireless network, for computers that connect fine, the Netnwork ID remains solid and the connection looks stable.
- In the 'status' window on the wireless network, for computers that can't connect, the Network ID flashes in and out and the network speed bounces between 450.0 Mbps and 200.0 Mbps. Said computers eventually lose connection and then automatically reconnect only to drop out within an hour or so.
- All PC's are using DHCP and the addressable range is 99 on the NAS. More than enough for 7 computers.
- All computers are in the same room and the problem is evident no matter which broadcast channel I use or which frequency. (2.4 gHz or 5 gHz) It is now set to automatic in the Airport because it seems the most stable.
- I installed a WDN4800 PCI-e adaptor into one of the PC's that worked with a USB adaptor and it no longer works with either!
Very frustrating!
I did some troubleshooting with TP-link, thinking it was their card, but came up with nothing. They think it's the Airport.
The only telltale sign that the PC is not going to work is that Network name in the status window of the wireless connection. If it's flashing: It won't connect. If it's solid: it works flawlessly for weeks on end.
Has anyone seen this issue before? If so: what did you do to fix it?

SOLVED:
The Airport Extreme is dying. Why it works on some computers and not others is beyond me but, after replacing it, everything works flawlessly. I hope this is covered under warranty.

Mac wireless connectivity with DLNA-equipped Full Hi-Definition TVs

Dear Friends at Apple,
I have been an avid Apple Macintosh user/advocate since 1985.
Can anyone help me I establish what is Apple proposing to do with regard to DLNA (Digital Living Network compatibility with our Intel Mac OS X 10.x.x computers?
Background from <dlna.org> website ..
"About DLNA:
The Digital Living Network Alliance (DLNA) is a global collaboration of 245 of your most trusted brands, all working together to help you create the home entertainment environment you’ve always imagined."
So DLNA Wireless Connectivity is being adopted now by the majority of leading Full High Definition LED-LCD and Plasma TV manufacturers.
However, I am unable to locate any information that would suggest that Apple is taking any steps to ensure wireless connectivity between my Intel MacBook Pros, Airport Extreme router and Samsung Series 9 DLNA-equipped large screen LCD-LED TVs.
DLNA as a protocol has been established since 2003. In that time, these international corporations have joined the DLNA consortium:
http://www.dlna.org/about_us/roster/
Where is Apple?
Surely, given the Microsoft domination of the DLNA consortium, Apple faces complete exclusion from the wireless Loungeroom Entertainment DLNA environment.
As with "Rosetta", a Mac Airport Extreme/DLNA tranlation capability should be capable of development, in order to protect Apple users who do NOT wish to ever load MS Windows on our Macs. (I happen to be one of these Apple purists!)
I would be extremely grateful if anyone could advise me on:
1. Apple's plans for connecting to DLNA-equipped TVs and PVRs
2. The likely timing for availability of the Apple solution?
Thank you in advance,
Rob Moffatt
<edited by host>

This isn't the place to ask a technical question. You should take that up in the forum appropriate for your model of Mac.
But answering quickly, there are DLNA-compatible media server software packages available for Mac. Whether any of those would be what you are looking for I don't know. You can look here for a list, or search the web for something like "DLNA Mac".
Whether Apple has any plans for their own software no one here can or will say.

Intermittent Wireless Connection, Dropping Wireless Connection

I am asking this in hopes of finding at least some way to diagnose my problem and hopefully eventually solving it. My wireless connection currently drops at varying amounts of time. Sometimes I can go 20mins others merely 5mins. The Airport reads that I am still connected and have a strong connection but when I try to navigate to a page with the browser (either firefox or safari) it merely times out after trying to load the page for up to a few minutes. I have changed the channel and frequency of my router (first router I tried was a Trendnet TEW-432BRP) and I have no cordless phones or other possible wireless obstructions. (I do have a very very infrequently used microwave but being that it's on the other side of the house and I can be sitting next to the router I doubt this is the culprit)
Then I tried changing routers to a Belkin N1 Vision router. Same issues. Additionaly worth noting all other PC's and linux machines on my network (about 4-5 other computers) all work just fine with out dropping their connections (with both routers).
Then I brought my original machine (a white macbook less than a year old) into the apple store, thinking at this point it was a hardware problem with my machine. They the replaced the airport card twice and the logicboard once. Eventually decideing that they should just replace the whole machine. Now with my new unibody I thought I had finally illeviated the problem but now I am having the same issues with an intermittent connection again.
If I turn off the Airport card and turn it back on again usually it will reconnect and allow me to browse again. But not always. The odd part is that generally when using another program that accesses the net the connection does not seem to be interrupted (such as with bit torrent). Very odd.
Anyway I tried using my computer at a friends house with the same trendnet router (his router but same model) and still the connection issues persist. Any ideas on what I can do or try to at least even begin to understand why this is happening would be helpful. I want very much to get to the bottom of this. Thanks for your help.

You didn't get the Apple Store to replace a white MacBook with a unibody?!
Anyhow - the connection problems could easily relate to an incompatibility between OS X and the router in question. Or it could simply be a setting on the router that isn't working well. To assist in the diagnosis... can you please supply:
1) The security mode of the router? (WEP or WPA/WPA2 and AES or TKIP).
2) The network mode (G/N)?
3) The signal strength as reported by Airport (RSSI)
You can get most of this information (all except the security mode) by holding the option key down whilst clicking on the Airport icon in Finder. For the security setting you can go to your routers configuration screen (or you can get it from the command line).
Cheers,
Rodney

Wireless connection drops and doesn't reconnect (netcfg, wpa_actiond)

I use netcfg 2.5.4-1 and wpa_actiond 1.1-1, B43 driver (BCM4318 wireless card) with firmware.
$ uname -a
Linux vekta 2.6.32-ARCH #1 SMP PREEMPT Mon Mar 15 20:08:25 UTC 2010 i686 Mobile AMD Sempron(tm) Processor 3100+ AuthenticAMD GNU/Linux
Connecting works fine. I can connect using sudo netcfg <profile>, or it automatically connects me on startup.
However, after a few minutes (up to 15 at best, usually 3-5) the connection is dropped. dmesg prints:
"No probe response from AP <macaddress> after 500ms, disconnecting."
However, netcfg isn't notified of this event, and still thinks the profile is connected. So I have to use netcfg -r <profile> to reconnect. Isn't netcfg supposed to notice this connection drop and try to reconnect again automatically?
Also, is there any way to increase the 500ms threshold mentioned in the log? I don't think I ever had this problem when I first installed arch in november/december last year.
Thank you.
