Time Capsule Wi-Fi slows down over time

Hi,
My Time Capsule 2 TB (running firmware 7.4.2, which is the latest version for my model Time Capsule) has an annoying habit of running slower and slower over time, eventually requiring a restart...
It becomes worse and worse gradually. At some point, transfer rates get very slow, websites take ages to load, connections even start to drop... and that's when people connected to my network start asking: "What the %($) is going on?". I then restart the Time Capsule, and everything is back to normal (for a while).
This repeats about once every month. I'm not satisfied with one month of continuous uptime on a Wi-Fi base station... I'm used to such devices running for a year or two before they may eventually require a reboot.
Has anyone else had this problem? Should I try to exchange the Time Capsule for the new model (running firmware 7.5.1)? It seems like Apple isn't planning to release a firmware update for the older model, even though it's still under warranty and obviously has a few glitches...
Tim

I've got this exact same problem with the older Time Capsule. Mine drops to around 10% of the original speed over time. Mine requires a reboot too.
I was thinking of buying a new one, thanks for saving my money.

XY dot plot slows down over time

In my VI I am using Express XY graph to plot a continous stream of XY coordinates over a contstant domain and range. I would like to keep the trail of these points.
Initially, plotting is very fast. But it eventually slows down to a crawl as point keep coming in. I have disabled autoscaling and smooth updates, but still the same problem.
Is there any solution to this, other than periodically reseting the graph?

Hello Amir,
I�m assuming that your data is being streamed into an array, and that you are then plotting that array on the XY graph. If this is the case, the XY graph has to rewrite itself every time, since XY graphs are a one-shot display. They are not set up for streaming. As your data keeps streaming in, the array gets bigger and bigger, causing the XY graph to take longer to refresh, slowing everything down.
One solution is to only plot the last x number of data points (x based on how fast you want it to refresh vs how much data you want to see). I�m including an example of a circular buffer than does just this. You�ll have to modify it for your data and for the XY graph, but the idea is the same.
If none of these suggestions help, please
post the software and versions you are using, the applicable portions of your code, and any other information that may help, and I�ll be happy to look further into it.
Have a nice day!

Time-Capsule Network Speed slows down

The TC will work fine for about a week and then inexplicably begins to communicate at a very slow rate over the wireless network. If I cycle power on the TC,, it will resume normal performance for about a week, and then slow down again.
I've taken to monitoring the TC wireless speed using the airport utility. My airport devices will operate normally at about 54 Mbps and my PC clients at about 113 Mbps (I have Netgear N cards in the PCs that operate at about 108 Mbps). When the performance drops, my Mac devices will drop to around 5Mbps and the PCs will drop to 54 Mbps. Performance will continue to degrade until everything is running at 1 to 5 Mbps. I reboot the TC and everything returns to normal for another week.
Any thoughts as to what could be causing this?

Hi and welcome to the forums.
I'm not a wireless expert, but after having wireless networks at home for more than 5 years with Apple stuffI made some observations.
First, there might be issues with other networks in your neighbourhood. Many posts suggest that there should be at least 5 channels between wireless networks, e.g. 1 - 6 - 11. Set it with AirPort Utility.
Second, something called "noise" from other electronic equipment as microwave ovens and machinery.
Thirdly, having different types of equipment's and networks and speeds mixed together might not make the best network. We have the Time Machine set as working in the 5Ghz area with only the "n" protocol, while another device from the Internet Service Provider broadcasts in the slower bandwidth. In this way the slower wireless computers are running on their own net.
Fourthly, reception of the wireless network can be an issue. One older PC has been provided with an extra antenna, and that helped a lot with an nearly 100% increase in speed for that machine.

Code Slows Down Over Time

While using LabVIEW to code an optical sensor that is used to see when a coin passes through a passage, the code will initally run at a fast enough rate to read a coin falling through it. Yet as time goes on the while loop the sensor is within slows down to a point where it is not quick enough to see/detect a coin falling through. There are two while loops running in parallel, that may still be causing some issues in priority?
Thanks in advance,
Ben

Along with what crossrulz said, your acquisition to find the coin is a little funky. You're pulling a single sample each time that loop runs, so you're limited to the loop rate of that loop for find the coin.
Instead, you should configure your DAQmx task to do hardware timing at a fast(er) rate and then pull all available samples with each iteration. Then you can see within all of the new samples if there is a coin when there wasn't previously (same logic you currently have, but on a data set). For example, you can have this loop timed to run at 20Hz, but your data is acquired at 1000Hz and chunks of the data can be analyzed at a time. This way is much more efficient than what you're doing.

EA6200 slows down over time and needs reboot

Anyone with a EA6200 notice it slowing down after about a week of use? I just replaced my e2000 with a EA6200 and its runs very well for about a week. After about a week I notice it slows down. Pages start loading very slow on all of my devices on my 2.4ghz and 5ghz ssids. It slows down to a point where it takes forever just to get logged into the router to and get to the page where I can reboot it so I know its the router. Once I reboot it, it runs great for about another week. Its using newest firmware. I have 2.4ghz set to 20mhz and 5ghz set to 80mhz, channels set to auto. Nothing to customized beyond that.

Try:
Connectivity => Administration => Cut through Forwarding => Uncheck
If IPv6 isn't required by your ISP; Connectivity => Internet Settings => IPv6 => Edit => Uncheck Enable
Media Prioritization => Enable => Check
Media Prioritization => Settings and apply accurate Downstream and if available Upstream values; Initially keep all devices and Apps normal priority
If you have throughput issues on Wifi try Disabling WMM support (EA6200\6400); if no difference is notice re-enable WMM
Please remember to Kudo those that help you.

Safari slowing down over time

Hello,
     My computer has been acting up lately. It seems that everytime I've been on safari browsing the internet, It gets slower and slower but speeds up again after a while. I ran the EtreCheck application (below) and said that com.apple.mrt.uiagent.plist failed. I've been on a lot of other discussions about safari being slow and this is one of the problems. I've already checked my HD drive and it is running fine and clean. I'd like to get this fixed as soon as possible.

Slow Performance Over time, Drawing Access Forms

we've been using a small access database for almost a year now, written from scratch using only Access 2013
over time drawing of one of the forms slows right down, once the form is draw its fine, but if you switch to a different form at the top then switch back it draws slow, maybe 7-8 seconds compared to the usual 1 second, sometimes it can work all day no problem,
sometimes after an hour it starts drawing the form slow, the only way to cure it is to restart the machine.
Logging off and logging back on doesn't cure it, only restarting it, it does get restarted every night automatically as an attempt to help the problem
this happens on 2 machines, both have intel HD graphics, (previously one was using a NVidia GT 250 which had appalling performance in design mode (even with hardware acceleration disabled) so we switched to the on-board, although this issue happens
with both machines)
Back end gets compacted/and repaired every night on a schedule as I did notice a big slow down if you let that go a couple of weeks, I've decompiled/recompiled the front end, short of re-writing the form I'm not sure what to do, it does have a lot of controls,
around 30 textboxes 1 combo box + 20 or so labels and 4 buttons, one embedded report, it only happens on this one form, I have embedded reports in other forms which don't have the same issue and have the same number of controls.
I'm a bit of a loss, its not a huge issue, but just an annoyance, when I get time I'm tempted to try recreating the form from scratch, but there is a lot of VBA code behind it, before trying that just wondering if there are any suggestions to improve performance?
*edit* the form is loaded from a list of customers, so it gets opened closed a lot, I thought simply hiding the form instead of loading/unloading all the time would speed it up, it does slightly improve the speed after viewing the second lot of details,
however it suffers the safe fate of slowing down over time, it seems to be only drawing the form and not accessing the db

I think you would benefit from a code review by a strong Access developer. What you are describing is not normal and may be caused by systematic programming choices.
-Tom. Microsoft Access MVP
Just wondering, once this does happen going into design mode on any form is slow to draw, but only the one form at runtime once it starts happening.
the only visible difference apart from waiting is seeing the 'property sheet' on the right hand side gets visibly drawn left to right on any form once this happens, switch back to form view you see it get wiped out slowly, fade from left to right as it blanks
the form out
I had this 'slow' behaviour constantly with the NVidia card in one of our machines, even on new blank databases.
I'm not even sure if this is linked to the form I've made or not, its just the only reason I notice it is that it's frustrating to use.
Is this code review idea something that people volunteer to check or is it a paid service?

Why does project save slow down over duration of project life?

I notice when I'm editing in a project in Premiere Pro CC, the auto save or even if I just save, the save slows down over time. You can slowly see the save bar going slower and slower over time. Even if I don't add any new media or import different files the save still goes a lot slower overtime. Sometimes the save bar will hang at a certain point for 20 secs or so and then continue. I understand if I add more media, files, pics, music etc... the save will take longer. But why does it do this if I'm just editing with some effects? Is it something to do with the cache folder getting too large or that I have too many auto saves? Should I clean out these folders? Also if it hangs at one spot for 10 secs or so is it because there is a corrupt file somewhere?
I just find this very frustrating if you are saving every 5 mins and you have to wait for 30 secs for a save.
My specs: Mac Pro 2009
Processor 2 x 2.26 GHz Quad-Core Intel Xeon
Memory 32 GB 1066 MHz DDR3 ECC
Graphics NVIDIA GeForce GTX 680 2048 MB
Startup disk SSD

I can answer some parts:
The auto save works as a five project silo. Once the list gets to 5 saves, it starts to write over. Also the auto-save only saves the project--no assets, no renders, thus the file is relatively small.
applying aneffect (filters transitions, etc) causes the program to create a new file as Premiere does not modfy the original asset. The more effects that are used, the more files that are created. When you finally export, the AME creates a single file, once again, not affecting the original assets.

Time capsule is very slow on wired Ethernet - tested from multiple sources

I purchased a 2 TB Time Capsule today. I want to use it for automatic backups of my Macbook, and I also want to use it to store files from my Windows PC's.
My TC is connected to my network using wred Ethernet only (Wireless is disabled in the TC)
My problem is that transferring files to the TC is incredibly slow. I have been doing some research and found lots of articles that talk about wireless interference and various problems with interoperability between WiFi flavors. None of these would seen to apply as I am using only wired Ethernet to transfer my files.
I also found a couple of discussions that describe how to make a change to the Mac's TCP/IP configuration to avoid a strange network condition slowing things down. This solution doesn't seem applicable as I am seeing the performance problem regardless of where I copy files FROM (I have a mixed environment with Windows and Linux and Mac systems)
Also, I am aware that the inital backup with Time Machine will be slow but I don't think that's relevant to my situation.
My TC is configured for file sharing so I can read and write files from my various Windows systems on the network. When I copy a set of large files to the TC, I see a typical transfer rate of 5 - 6 MB / Second. To me, this is completely abnormal and here is why: When I copy the same files, from the same Windows system, to a server on my network I get about 60 MB / second or about 10 times the transfer rates.
The TC is running firmware 7.4.2.
What gives?

I also had the same issue. My Time Capsule was connect to the Linksys router WAG325N. I had a wireless network broadcasted from the Linksys and a different one from the Time Capsule. When connected to the TIme Capsule wireless network i pinked the Linksys router and got 10% to 30% pack loss. When i pinked the Time Capsule i got 0% loss. I used the AirPort Utility and changed the "Internet" "Ethernet WAN Port" from automatic to "10 Mbps/Full Duplex" and this seem to fix the slow internet.
I guess the Linksys and Time Capsule as issues with port speed negotiation.

Hi iv got a sky router downstairs and a time capsule up stairs how do i set it up so that it just extends the sky wifi and then the hard drive in the time capsule is accessible from all over the house thanks

Connect an Ethernet cable from one of the LAN <--> ports on the back of the Sky router to the WAN (circle of dots icon) port on the back of the Time Capsule. This connection must be maintained at all times.
Then, using the setup "wizard" on your iMac illustrated below, configure the Time Capsule to create a wireless network that uses the exact same wireless network name and password that the Sky router is using.
You can get the setup wizard going in several different ways, but the simplest might be to click the WiFi icon at the top of the Mac's screen and then click on Time Capsule under the heading of New AirPort Base Station.
The wizard will open up and analyze the network, then the suggest the correct setup. The example below shows an older AirPort Express that is about to be setup in the same way. You will see a Time Capsule icon on your screen when you run the setup wizard.

AirPort Time Capsule Model A1470 Shuts Down

Hello!
I purchased an AirPort Time Capsule last week for more than $300 to replace Model A1409, which suddenly shut down and never came on again.
The new AirPort Time Capsule (Model A1470) shuts down at least 4 times a day every day. I unplug it and plug it back in and it reconnects. This happens at random times when I'm using the computer and when I'm not. Sometimes it happens when we're watching a movie on the TV and after I get it up and running again I need to enter all of the password infromation on the television again.
This is a 2TB Model A1470.
Having reliable wifi is a must because I am a work-at-home online educator and have 40-hours per week of office hours with continuous IM access to my students.
Should I return it or is there something I missed?

When you say shuts down.. what does that actually mean??
The new AirPort Time Capsule (Model A1470) shuts down at least 4 times a day every day.
Does the LED in the TC turn off??
Does it blink amber??
Can you connect a computer to it by ethernet and still get internet??
The requirement to re-enter info like password on the TV seems rather strange.
If the TC just stays Green and the effects are in the network and not apparently on the TC itself.. please try a full factory reset of the TC.
Please rename it.. Call the base station TCgen5.
Please set a different wireless name to both bands.. TC24ghz and TC5ghz.
Even set fixed channel for 2.4ghz and you can also try 5ghz although I doubt it will accept the value.
Make sure you use WPA2 Personal security with a suitable password, 8-20 characters pure alphanumeric.
If you get no improvement then yes you should return it as it seems to be faulty.

RFGuns slowing down several times a day

Hello,
RFGuns in our warehouse really slow down several times a day and start taking time. I am wondering if this is a network problem. Any ideas where to look? Thanks

Try to determin when the issue started and whether or not any changes went in when the problem started, updated security measures? new access points, switches and such? any thing related to RF connectivity has changed?
After checking with network team, they should monitor, look for network issues, check sygnal strength
1. check with network security team, ask if they run scans durring the times you see slowness
2. check for batch jobs that might suck system resources (financial batch jobs can slow entire sytems)
3. check for firmware updates for the devices, some devices have known issues w/newer secure networks
4. do server analysis to make sure enough resources are devoted to the boxes that handle the transactions
good luck

I just did an Time Capsule firmware update and now my Time Capsule is dead. What happened?

That is very bad.. how old is it??
The Gen4 TC can die this way.. it is not usual but it happens.
Leave it for several hours to cool off. Do a factory reset immediately when you try to restart it.
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.
Tell me exactly what the LEDs do throughout this process.
Both the main one at the front and the LED on the ethernet ports which should all flash during bootup.
If it is less than a year.. of course Apple will replace under warranty.. 2 years in some places.. Europe .. places with stronger consumer laws. If you have applecare on a computer it should still cover the TC.
I kind of doubt you are going to get this going again... but we can try.

My DSL has slowed down over the last few months

Guys;
My DSL has slowed down over the last few months. I had the service that is up to 1.5 M and I used to get 1.2 ish on the verizon speed test, lately I've been getting between .9 and 1.0 at the most. I got the info from the speed test and here is a portion of that info:

Airport Time Capsule stop send wireless signal, Airport Time Capsule stop send wireless signal

After instaling several times, alway after a while the wireless router stop sending the signal, or does not start up like in the morning, especially from a windown computer.
Out house have several computers in Windows and Mac, iphones and ipads and itouch mac book pro,
How come the router will not start up after a "night of rest"

Unfortunately, a solid amber is light is not a good sign.
Try a complete Factory Default Reset on the Time Capsule using the steps below. This procedure will not affect any of the data that you have stored on the internal hard drive.
Power off the Time Capsule for 15-20 minutes or longer
Hold in the reset button on the back of the Time Capsule first, and keep holding for an additional 9-10 seconds while you simultaneously plug the power back in to the Time Capsule
Release the reset button after the 9-10 hold period and allow a full minute for the Time Capsule to restart
The Time Capsule light should normally stay solid amber for about 30 seconds and then change to a slow, blinking amber light, indicating that the Time Capsule has been reset and it can now be reconfigured.
If you try the Factory Default Reset a few times and the light stays solid amber, unfortunately the hard drive has failed, or there is an internal power supply issue with the Time Capsule.
You should take the Time Capsule to an Apple Store.....if you have one in your area.....or contact Apple Support directly to discuss your options.

If the Time Capsule is out of warranty or not covered by AppleCare, Apple will not offer repairs but there are some shops that specialize in this type of repair. See this link for more details:
