IMac wifi signal fluctuates between -24 and -80 other clients stable.

I'm experiencing Airtunes dropouts. The problem seems to be fluctuations in signal strength as shown in the screenshot in this link: http://gallery.me.com/alex.slaets#100343/wifi&bgcolor=black .
Network:
3 Airtunes express in 802.11n only 5 GHZ mode, configured to extend the range of one wireless network.
Clients:
1 iPad.
1 iMac.
All software and firmware is on the very latest version.
Observation:
As shown in the image, the signal strength S/N remains stable at -24/-95 db for all clients in the network EXCEPT the iMac (22:FF) which fluctuates between -24 and -80 in 5 to 10 second cycles.
The iPad (C8:FB) is located near the iMac and its signal, remains stable.
Any ideas on what this might be ?

any cordless phones nearby ?
perhaps one of your neighbor's wireless networks is interfering with yours. download iStumbler (free) or AirRadar (it has a trial period) and note the channels other networks in your vicinity are broadcasting on. *change the channel(s) of your network as far away as possible from those*.

The 5.1 update is causing my WiFi signal to fluctuate between 2 and 3 bars

The 5.1 update is causing my WiFi signal to fluctuate between 2 and 3 bars. I am 15 foot from my router, and never had this problem. I have a 4s phone. Anyone else having this problem?

The wifi signal strength indicator was one of the changes according to the list:
http://en.wikipedia.org/wiki/IPhone_OS_version_history
If your actual connection speed is about the same, I wouldn't worry too much about the indicator.

IPod Touch WIFI Signal Fluctuates After Upgrading to iOS4

I upgrade to iOS4, and now my iPod Touch 3rd gen's WIFI signal fluctuates now matter how close I am to my Airport. I can be right next to the Airport and the signal will go back and forth from one bar to three bars. Never happened with OS 3.1.3.

For those having Wi-Fi issues... What level of encryption are you using on your routers? And is your router at full power? I'm not really having any Wi-Fi issues, I'm using WPA-PSK [TKIP] + WPA2-PSK [AES] and I switch my router to full power after I started having the iOS4 batter problem. (it was on "Neighbor Friendly" Mode). I was worried that a weaker signal would contribute even more to the already existing battery drain and I'm figuring that having the encryption on the highest level is also affecting the battery as well, but I haven't tested the difference.
Using WEP + hidden SSID at home (I have some devices that choke on WPA). Open WiFi access with authentication at work. Router signal boosted from 42mW to 70mW using Tomato firmware.
Also, if you're using a Pre-N router, disabling "Neighbor Friendly" mode means you're using a ton of 2.4GHz channels. This prevents any neighbors near your home from using WiFi, because you've stolen all of the available channels. I had to set up my sister-in-law on Wireless-A, because her backyard neighbor hates her, and turned off "Neighbor Friendly" mode on his router. What a pain.

I cant connect to wifi but my laptop can and my other phones can.ived done all the recommendations in ipad support but still cant connect..what else shall i do?

i cant connect to wifi but my laptop can and my other phones can.ived done all the recommendations in ipad support but still cant connect..what else shall i do?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Mid 2010 iMac Wifi signal strength issue

I am having issues maintaining a robust Wifi signal on my 21.5 inch 2010 iMac with 10.6.5 installed.
my symptoms are very similar to what is described in this post:
http://discussions.apple.com/thread.jspa?threadID=2596933&tstart=0
in addition to that I am experiencing the following symptoms:
can't print to HP wireless printer
remote app for iphone doesn't find the iMac
mobile mouse remote app doesn't find the iMac
can't ping the iMac from Windows laptops on the same subnet or from the router itself
accumulation of send and receive errors in Network Utility
these symptoms occur after the machine has been connected to wifi for 30 minutes or so. Turning off Airport and turning it back on temporarily fixes the issue. the Mac firewall is turned off.
as reported in the post mentioned above, signal strength for my Windows laptops and other devices is consistently -25 but the iMac signal strength fluctuates wildly.
One more troubleshooting step that I have taken is to install Windows 7 on a boot camp partition to rule out the iMac hardware and physical location as the issue. While booted into Windows the iMac did not exhibit any of the above symptoms and held a steady -25 strength signal.
Lastly I am using a TrendNet Wireless N Access Point but have also tried an Apple Extreme and Express (both N). I've tried 2.4Ghz and 5Ghz on various channels. I've even tried dialing down to G mode.
I've read other posts about DNS settings, Static instead of DHCP addressing, etc. and none of these has solved this issue.
Thoughts anybody? TIA

Update concerning additional troubleshooting steps that I have taken.
1) did a clean install of OS 10.6.3 onto an external drive and managed to replicate the issue....so that rules out apps, preference files, etc.
2) managed to get a little bit more stability by setting up an Airport Express in 5Ghz mode with Interference Robustness turned on and the multicast rate set at 9Mbps....of course ios devices don't do 5Ghz so I still have to run another AP...so not an acceptable solution.
What else do I need to do to prove that it's a Mac OS software issue?

3G Signal Difference Between iPhone and iPad.

I have an iPhone 3GS and a iPad 64GB 3G/Wifi. May question is this:
When I am in public I appear to have a major signal differene between the two devices. When side by side, the iPhone has one bar while the iPad has five. Plus the speed when using the internet is reflective of the signal strengh. Does anyone know why there would be this large of a signal difference? And what would be causing the problem?
Thank you for your help and sorry if this is a repeat post.

As this question doesn't appear to have anything to do with iTunes, you might want to post it in either the iPad forum or iPhone forum.
Best of luck.

Crystal Report Output is Fluctuating between USA and European format Issue

We use Crystal Report 10 .net for our web development in asp.net. We export crystal to PDF Or excel. And it is showing different format for date and decimal points. Its not doing this all the time, but its like every other time I run the webpage then report exports to pdf shows dd/mm/yyyy format, then next time would be mm/dd/yyyy format. Same things with numbers like
10,000.50 would show like 10.000,50.
Is something corrupted or there are any hot fix if this is an issue?
The weird thing is, its not continuously doing this but its fluctuating between this formats.
Please help....

Best I can suggest is trying the latest Service Pack:
https://smpdl.sap-ag.de/~sapidp/012002523100005985482008E/cr10win_en_sp6.zip
More downloads are here:
http://service.sap.com/sap/bc/bsp/spn/bobj_download/main.htm
Other than that, as CR 10 has been out of support for a number of years, I have no way of testing or reproducing the issue. In order for me to do any troubleshooting, You'd need to get to a supported version of CR. Either CR XI r2 (11.5) or CR 2008 (12.x). 12.x recommended as CR XI r2 will be out of patch support next month.

I need to reset my time capsule/airport every day - time capsule has green light but I don't see any wifi signal on my mac and other computers.

as many of you do, I use time capsule as airport, too...
It worked fine for 6 months or so after I bought the new time capsule. (I bought it in September 2012.)
Since the beginning of this year, I had to reset, and power off and plug it in almost every week, then now I need to reset and power off and back on again every day...
When I first set up the time capsule, I followed the instruction with the manual.
But, now I am so lost and don't want to reset every day for wifi connection.
Anyone has problem like me or knows how to solve this issue?
Please help..
I have MacBook Pro OS X 10.8.4 & my roommates have PCs. (just in case if it helps...)

For PC it is important the wireless has names that are compatible.. short.. like 10 characters.. but 2-20 is fine. no spaces.. and pure alphanumeric.
Use WPA2 personal only.. with pure alphanumeric password .. again 10-20 characters should be fine.
The latest firmware is a dud. Go back to 7.6.1
Open the airport utility.. click on the TC and holding the option key click the actual version number..
Go back to 7.6.1 is simple.. just select it and away it will go.. ignore future requests for upgrade.. you can also tell the utility not to check weekly for updates. You will need 5.6 utility for this I think..
So do the firmware downgrade.
Then do a factory reset and follow the name information above.. for TC name as well btw.. wireless name/s and disk share name.. which by default is data and that is fine.
So some instructions in...
The Factory Reset.
Power down the TC.
Hold in reset. and keep holding it in. Be Gentle! It is a tiny surface mount switch with a plastic lever.. Attempting to push it out the other side of the TC will not make the switch turn on better.
(I fix TC and have several reset levers bent over and jammed or broken off).
Power on the TC.. remember with the reset held in.. this needs three arms.. a friend or power switch you can get to with your feet..
Keep holding in reset for about 10sec until the front LED flashes rapidly.
Release reset and wait .. the boot will be slow as it deletes previous setting.. only from router side and pulls out the factory defaults. No files are deleted on the hard disk.. but the name of the TC may change.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.
You can also load airport utility into a pc and get access to all the settings. Untick the box for firmware updates.. it will still bug you occasionally.. regardless of the setting.. just ignore it..
You might still need to do the occasional reboot of the TC as well.

I have 2 iMacs, one has a thunderbolt port and the other has a mini display port. Would it be possible to use one as an extension of the other? If so what cable would I need.

Hi,
As the title of the thread says. I have an older iMac with a mini display port and a newer iMac with a thunderbolt port. Would it be possible so that the older iMac is an extension of my new iMac. The reason for this is because logic x can be a abit clustered on one screen.
Thanks

If you'll be using the 2010 iMac as the display, a Mini DisplayPort to Mini DisplayPort cable.
It's not possible to use the 2011 iMac as the display through Target Display mode in that configuration.

Is it possible to download and save all texts exchanged between myself and one other person onto a file on my laptop?

There are many hilarious and sweet texts between me and a friend, and he lost his phone. Therefore, I am now the only one who has access to them, and so I am wondering if I can somehow download them onto my MacBook so I can send them to him as an attachment. I am using an iPhone 3GS with IoS5.
Thanks!

Any issues with file sharing between Windows and latest Mac client?

We're running Lync 2013. My Windows client is 15.0.4551.1005. Mac client is version 14.0.8.
I open a conversation with a coworker on his Mac. I then try to share a png file. He clicks accept but then my client says the attempt timed out, and his client says that I canceled the file transfer. The coworker then boots the Mac into Windows and we try
again, and the file share works fine. When I jump on my Mac, I can send files to his Mac without issue. When he tries to send from his Mac to my PC it fails, but when he tries to send from Windows on his Mac to my PC, it works.
I can't find anything specific in the logs that would indicate a firewall issue. Is there a bug with file sharing between the Mac and PC clients?
Thanks,
Matt

No, There isn't a bug with file sharing between Mac and Pc client.

How do I use pots on my client machine to change values, from the field, on my server machine and all other client machines?

I am using Lookout 4.5, build 12, and I am having a problem concerning pots. I have data tables created for the different size sewer stations my system monitors. For each station, there are setpoints for starting and stopping of the pumps. I want to be able to change the setpoints for a station on the client file using a pot and have it change on all other machines running Lookout. I did this in 3.8 using DDE, but I don't want to use DDE anymore.
I created a pot on the client file and URL'ed it to a pot on the server. On the server I created a table with a generic member "A" named "Lead Setp" and then created a member "A1" named
"C5_1LeadSetp" then a member "A2" named "C3_1LeadSetp" and so on....
In this table I connected the generic member "A" to the Pot I created on the server, and I connected A1 to its corresponding setpoint signal coming in from the field.
On the client file I connected (in the table similar to the one on the server but with all signals for the station) the "A1" member to the setpoint signal coming in from the field, and I connected the "A" member to the Pot I created on the client file which is URL'ed to the pot on the server file.
But, when I change the value of the pot on the client file, only the pot on the server and the "A" member in the table on the server change to the value of the pot on the client. The "A1" member whose screen I am changing the values from on the client does not change! This is the last thing I have to do and my file will be completely converted to 4.0. Does anyone have any ideas?
Thanks for any responses..

Hi Jason,
If I understood your task correctly, you want to change the Setpoints on the Server DataTable using Pots from different clients. And also reflect these changes on the clients locally.
You correctly remoted the Pots on the Clients to the corresponding Pots on the Server. However, you do not need tables on your clients. All you need is Expressions on each client to the particular cell of the Clients.
So, to summarize: On the Server, the Pots write to the DataTable. And since the Pots on the Clients are remoted to these Pots on the Server, you can affect any change using these Pots. Because of the common remote source (Server Pots, i.e.) all of these Pots will always be in sync. Finally, to get the Setpoints on the Clients, just insert Expressio
ns to the Server's DataTable.
I am attaching a simple example (exmpl.zip) which does this. There are three processes -- My_Server, My_Client1, and My_Client2. I had them setup on the same machine so the paths are all process relative, but you can always change those to computer relative or absolute and move the client processes to diff machines.
Hope this helps.
Rgds,
Khalid

My wifi constantly switches between on and looking for other networks

while I am on my wifi network and internet successfully I notice that it switches between saying WIFI ON and LOOKING FOR OTHER NETWORKS. How do I get it to stop looking for other networks because it is successfully already connected to the right one?

My startup disk is "almost" and sometimes full, HD space fluctuates between 500 and 900GB used?

so I bought an HD big enough to prevent this happening but I get the on error that makes me quit all app on a daily basis. I check on info and says that HD sometimes has nearly 900GB used and other times 500 and bit, in both ocasions have checked after the error appears and despite the difference between available space forces me to quit all applications anyhow.
1.- I dont understand why the massive fluctuation!?
2.- I resist to believe that you must keep less than 500 GB in your hard drive if you have bought a more expensive HD (1T) so surely there must be something wrong.
3.- Admitely am a newby to mac so half the posts already answered here do not make any sense to me as they are very high spec with terms am not yet familiar with, if you can help me using basic guidelines and steps to follow you would make my month as I cant even work here anymore, am about to despair, have tried all possible options including the failed Mckeeper which I had to remove with Mac cleaner application in the end, Onyx and I review my files constantly, emptying the bin etc except checking if any email was been sent countless times and stayed stuck somewhere in my system as I read somewhere because I just dont know how to do that, it might be an option.
I also have an annoying pop up from BT showing up every now and then as well which tell me I have given permission and which havent got a clue how to cancel, this makes me wonder if is there something like a virus trojan or similar mac equivalent on my system causing all of this problem.
I'm sorry that I migrated to avoid these kind of problems but found a lot easier to run an antivirus on my pc than trying to solve a mac problem! Please help me

First, empty the Trash if you haven't already done so.
Use a tool such as OmniDiskSweeper to explore your volume and find out what's taking up the space.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To really see everything, you have to run it as root.
Back up all data now if you haven't already done so. No matter what happens, you should be able to restore your system to the state it was in at the time of that backup.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
After installing ODS in the Applications folder, drag or copy — do not type — the following line into the Terminal window, then press return:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
I don't recommend that you make a habit of this. Don't delete anything while running ODS as root. When you're done with it, quit it and also quit Terminal.

Airport symbol/icon is flashing black as if searching for a wifi signal despite being connected and having internet

Is anyone else having this issue, while it is not really a significant issue because it still connects recognizes the signal and allows me to have internet, it is annoying to see the icon flashing when you look at the time. This issue has only began a few weeks ago.

Thanks for the replies... I don't go on forums much but BT has not been any help so I'm trying it. Anyway, just got off the phone with the level II team who has confirmed that no one has ever reset by IP profile.... wonderful. So, essentially I was lied to on muliple occasions. Supposively being reset now and will get a call back in 3 days as it stabilizes.
However, in the meantime... here's the data from my router and the latest Speed-test copy/pasted - let me know if you need anything else, but I do think this IP profile reset will work eventually:
