Wired NIC Atheros AR8152 v1.1 disconnects over time

Hello!
I'm having a bad time with my Atheros AR8152 nic, when i connect to a wired network it just disconnects past a few minutes.
Some context information:

lsmod:

After the OS boots, i perform dhclient enp1s0 or dhcpcd enp1s0 and i can manage to connect to the wired network for a few seconds, at most a couple minutes:

In order to reconnect, the only way i found is restarting the router and putting down/up enp1s0 and running dhclient enp1s0 again. Then start again all over...
It may look like a router problem, but i'm using the same router with a debian box set with dhcp and ethernet connection works fine.
Some additional information: when i installed the base system, i did it via this nic and it went smooth. Maybe an upgrade broke this?
I've been searching the forums but couln't find a similar case to mine. Any ideas?
Thanks in advance!
PD: Sorry about my bad grammar, english is not my mother language :P

Hi. I'm experiencing the same problem on my NB too!(using Atheros AR8151)
It happens commonly when I play facebook game.
I also found out that even doing nothing(just idling my NB) for some times it will happen.
When it happens, I have to unplug my ethernet cable then plug it to let NetworkManager to reconnect to temporarily solve this problem.
I've been using Archlinux on this NB for two years. Can't remember exact when this problem first occurs. Maybe in a month.

When i plug the USB for my iPad into my computer it will connect then disconnect over and over again untill i wiggle the usb around alot. This is happening to all my ports. But not on the other computer.

Hi. Whenever i plug my iPad (Happens with ipod and iphone too) to my computer usb for itunes is will connect, then disconnect over and over again. It has happened for a long time but doesnt happen on my other computer. how do i fix this?

If you have a spare cable, try using that. But the fact that this doesn't happen on your other computer (I assume using the same old cable) leads me to conclude that something else is at work. Maybe even the "bad" computer.

Problems with atl1c module (Atheros AR8152 v1.1)

Hey guys,
I discovered my ethernet isn't working anymore today (I'm using wifi all the time), when I updated to the new kernel version and found my wireless dysfunctional. Luckily I fixed wifi after all (had to blacklist the bcma module).
Still I want to fix my broken ethernet now, but this gives me a hard time: I'm using a Atheros AR8152 v1.1 based card, so the atl1c module should be the thing to use and this must have worked for some time, since I had to install the wifi stuff somehow when setting up Arch some months ago.
All I get now are the following lines of dmesg's output:
atl1c 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
atl1c 0000:01:00.0: setting latency timer to 64
atl1c 0000:01:00.0: cannot map device registers
atl1c 0000:01:00.0: PCI INT A disabled
atl1c: probe of 0000:01:00.0 failed with error -5
All I got by looking around in the internet was a tip to disable acpi by booting with the acpi=off or the acpi=copy_dstd kernel parameter, but this didn't do anything besides leaving me with a more or less dysfunctional system in the first case...
Can somebody give me a hint on what to do?

Hello,
I am owner of AR8131 which runs with atl1c without problems.
Unfortionally it seems that module does not have any optional parameters so i guess it wont be "easy" fix.
hits:
check your bios for "NET AI" or w/e named function that checks for bad cabels ( got many problems in the past with nvidia cards if i remember correct with those type of functions )
In any case wish ya luck

Router disconnects over 20 times a day.

Hello
Since November last year that I have been troubled with constant disconnects from my router which leads to quite a bit of frustration, I have posted on this forum 2 times since then and my problem persists, the first time an engineer came over and after a few tests detected that there was a problem with my line and "fixed" it, after 7 days of stable connection, which was the recommended time to see an improvement on my line, it went back to disconnecting several times a day, posted again in the forum and sent an email to a mod explaining my problem, he got back to me and said the same thing the engineer said, there is a problem with my line and he would "fix" it, now for 2 weeks it did get fixed, didn't had a single disconnect, the line was up for 10+ days up to the day when I reported back to the mod and after seeing that my line was stable he recommended me to reset the router to improve the Internet speed as it was locked at under 4MB dl, at this point the festival of disconnects restarted up until today, just yesterday it disconnected 10 times in 1 hour, I'm really trying to keep a positive feeling about this and that it will be fixed but it has been almost a year already.

My mac book air suddely disconnects many times the wifi while using wifi

my mac book air suddely disconnects many times the wifi while using wifi

Lots of things can impact wifi connections. If you are at the marginal edge of the wifi range (which depends not only on distance, but what's between you and the transmitter) you may find the connection dropping in and out. Sometimes a minor repositioning of the computer or transmitter can solve the issue.
As well, interference can also create problems. For instance, microwave ovens are really good at disrupting 2.4Ghz signals, and that the frequency used most often in wifi routers--so if someone turns on the microwave and it's between you and the transmission point it won't be surprising if the connection drops. As well, metal blocks the signal fairly effectively, so if (say) ductwork is between the CPU and the wireless router there can be problems.
Finally, I've run into some combos of devices and routers that just don't seem to like each other :-) . That said, I've not hit that problem with either Air I'm running (an 11" and a 13"), though obviously I've not tried to connect them to every type of router out there.
Just this week I was at a hotel and in my room the hotel wifi was "interesting" with every device I tried (iPhone, Android phone, Kindle Fire, iPad and the two Airs) dropping connection regularly from the work desk. Turned out if I moved the devices over to the nightstand on the other end of the room (not the best work environment) all of the problems went away, so it clearly was a signal issue and the exact layout of that room and the hotel's wifi.
If the machine has a problem when positioned close to a variety of routers, then I'd suspect a hardware issue with the wifi card in the Air and get that checked by Apple. Similarly, if your problem is with your home router, I'd check to see if other devices also are getting dropped, since there could be a hardware issue on the router.

Cisco Pix 501 / DNS - DNS resolution stops working over time

Hello,
I currently have a Cisco Pix 501 with the configuration listed below. It connects to the public internet via a cable modem and acts as a DCHP server for the local LAN.
When it first turns on, all computers obtain the correct IP settings and can access the internet. Within 10-15 minutes, computers begin to loose access to the Internet. What’s strange is that each computer that lost Internet access can ping the remote address but cannot perform an nslookup. (it shows as Server UnKnown)
The DNS server is 167.206.254.2 which is the external dns server provided by my ISP. I can ping this address but the local computer is unable to use it for domain to ip resolution.
Then network used to have an existing Windows Small Business Server that was a DNS and WINS Server. I ran dcpromo to remove the role of the server and uninstalled dns via add/remove components.
Can someone please help me determine why the computers over time loose the ability to resolve domain names and therefore loose internet access? Can there be some bad DNS entries created? Is there anything I can run on the local computers to further troubleshoot dns errors? Is it possible that the existing Windows SBS server is still running DNS and therefore causing conficts in some way?
One thing to note is that when I reset the Pix 501, everything begins to work again but only for a short time until one by one each computer can no longer resolve domain names. Also, I noticed that once someone connects via VPN and disconnects, one of the local computers looses the ability to resolve DNS.

Wow...i didn't realize this was possible. I will certainly check the logs tomorrow via the existing thread but just to confirm, is this only true if DHCP is enabled on PIX?
In other words, I managed to work around this issue by applying static IP's to all computers and the internet works just fine.

Do Airport Express modems wear out over time

I periodically ( a few times a week) lose my connection with the Internet through Comcast. I have two Airport Express units n our home that is our wireless network. They are synced together. I will lose connectivity with one or both and have to disconnect from power for about a minute and then plug back in, then all is well until the next failure. Do these units wear out over time? Is there a better Apple product to use in this situation? I am using a Motorola modem in this process.
Thanks,
Mike

The physical law of entropy is stronger than God. Therefor, anything and everythign will break down given a long enough time. However, I think you may be worrying a bit too much here. Your express should generally last long enough.. until you plan to change 802.11n to another better format.
Yes, some go bad time to time, hence why limited warranty is only a year from DoP.
I suspect your issue may be due to interference. I'm curious what band are you using on those expresses.

ITunes sync bug causes space on iPod/iPhone to be gradually lost over time

This topic pertains to iTunes for Windows version 10.1.1 and most likely all prior versions. At the time of this writing 10.1.1 is the latest version.
I have clearly identified a bug with the procedure iTunes uses specifically to copy Music over to the iPod and iPhone units. A detailed description with steps to reproduce follows, but first the summary: Space is gradually wasted by iTunes erroneously copying certain tracks twice! The 2nd copy is not recorded in the itunesDB file, and space wasted on these duplicate tracks is counted under "Other" in the iTunes capacity screen. It is impossible to ever retrieve this space from the portable device without doing a factory restore on the Summary screen, which of course will also wipe out all your Apps, Videos, Photos, Music, etc at the same time. Hardly an ideal workaround!!
Details:
When several tracks are to be copied to the portable device; either an iPod or an iPhone, and I have successfully reproduced this on both an iPod nano 5th Generation and an iPhone 4, sometimes a track is accidentally copied twice while, one of the selected tracks isn't copied at all. The user will notice when this occurs, that during their sync, one of their songs just seems to be missing. Syncing again will then copy the track which was missed during the last sync, but unfortunately, the 2nd copy of the track that was erroneously duplicated remains. The track which is duplicated appears in the hidden folder on your iPod file system as both the AAAA.mp3 filename structure and the <track name>.mp3 file name. Oddly enough, when this bug occurs, the itunesDB does not associate to the AAAA.mp3 like it normally would, but to the <track name>.mp3 and the AAAA.mp3 file is just wasted space on your device which cannot be recovered without manually deleting this file (a task which is impossible on an iPhone without hacking the device).
It is easy to reproduce this. This is very obvious if you start with an empty, new iPod. Sync a bunch of tracks to your iPod (the more the better), in fact this cannot happen if you only sync 1 track at a time, then check to see if the number of tracks is equal to the number of tracks that should be there. i.e. did the sync seem to just miss 1 or 2 tracks?
Make sure "Enable disk mode" is checked for your device, and browse to (Drive Letter):\iPod_Control\Music\ and you will eventually find that exact number of files which have actual track names instead of the standard AAAA.mp3 type filename. Next, in iTunes, remove ALL songs and any other forms of audio (such as podcasts), from the device. Your music folder techincally should now be empty, but as you browse through the hidden Music folder in the device, you will stumble upon a couple of files that remain. These are the orphaned files I've been talking about.
The effect:
Over time, with repeated additions and removal of songs from one's device, these files accumulate. The iPod owner, none the wiser, will start to wonder why "Other" in the iTunes capacity display is continuing to grow. I was highly suspicious after cleaning out my iPod entirely, that "Other" was still showing 1.6GB!! I browsed through the filesystem wondering why which led me to discover tons of various music files in the music folder which shouldn't have been there (after all, iTunes shows no music stored on this device).
The Fix:
Some sort of bug is causing this erroneous duplicate copy to be generated, and then the database to actually reference the erroneous copy instead of the AAAA.mp3 copy. One workaround iTunes could actually build in some sort of enumeration function that scans all of it's internal F## folders in the Music folder looking for these orphaned files, and simply erase them if they are not contained in the itunesDB. Pushing out this type of behavior into a new iTunes release would also fix the problem for all the people who've already racked up GBs of wasted space as that space would suddenly become available again for apps, tracks, and other files.

Two steps forward - one step back.
Thanks to insight from others here I enabled disk use and went to [drive letter]/iPod/control/music
There I saw a long list of folders called F00, F01, F02 etc.
In my case there were 49 of them with roughly 400 files in each folder.
The bulk of the files were named ABCD.mp4 down to ZYXW.mp4.
In each of the fifty folders were, as predicted above, a handful of song files labeled as such - ie borntorun.mp3 or iseered.mp4
I opened each and every one of the folders, deleted the files with real names and synced the pod.
On my 120 GB the yellow "other" fell dramatically, down to under 1 GB. Which is under 1% of the total. Not great but acceptable.
So far, so good.
Now that I had fresh space I set about adding new songs to the pod.
Imagine my disappointment when I rechecked the F00 to F49 folders and saw that song name files had crept back in. Not as many, and I was able to delete them quickly and keep "other" under 1 GB. But still. It's like having crab grass or rodents.
Is there any hint that iTunes might address the underlying cause?
In the gripping process of deleting four or five files from each folder I noted that some specific files came up again and again. Just for laughs I'm going to delete and re-add those songs in case that helps.

Amount of key presses a user makes over time - BPM

Hi,
Im working on a small program that needs to get the amount of keypresses a user makes over time.
Basically its for calcuating the BPM a user is inputting. So a uers taps a beat for 5 seconds and the amount of tap is saved and multiplied by 12 to get the Users BPM.
So far i have this:
package Version1;

It doesnt seem to like me parsing int to string here:
String s = Integer.parseInt(i); Any ideas? or if youve got suggestions on another way to do it it'd be much appreiated.
Thanks!

Yikes, you've got that bit of code backward, there partner.
You use Integer.parseInt to parse a String into an int, not the other way around.
If you want to change an int to a String, do
String s = String.valueOf(i)or you can use the various formatters out there.

I ended up with 3 Apple IDs over time. How can I get it down to one account?

I ended up with 3 Apple IDs over time. When I sink my iPad, some apps won't sync because the app was purchased under a different account?
How can I get it down to one account and be able to sync all of my iTunes purchases (apps, music, etc.) on my iPad and iPhone?
This is driving me crazy! grrrr. :-)
I have .me; .mac and .icloud accounts.

Thanks. I was afraid of that. Darn Apple....we use Apple products because they are elegant and easy to use, why can't apple simplify the ID issues??? :-)
Thanks for the reply.

Is ther a way to speed up a Mac? Mine has gotten slower and slower over time. When memory comes close to full would that have an effect on performance? Is there a way to determine unused programs/software to remove and free space?

Is there a way to speed up a Mac (similar to de-fragging on a PC)? Mine has gotten slower and slower over time.
When memory/disc comes close to full would that have an effect on performance? How should I determine what programs/software to remove and free space?

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

SSRS line chart showing premium change pct over time

Hi,
I have an SSRS report sitting over a cube. I'm building a Line chart to show premium change over time by producer (there are currently 6 producers). I have the Producer Name, Quarter/Year, and Premium amt.
I want to have the premium line trend based on the percentage of change from Quarter to Quarter. Quarter will be the X-Axis and percentage will be the Y axis. The premium for the first quarter should start at 100%. Each premium line for
the producer should then change up or down based on the change in premium per quarter. The end result should look something like this: Can this be done using SSRS?

Setup a new Macbook Pro to minimize application slowdowns over time

Hi,
I own a dual G5 2.0 tower which has become (over time) extremely slow...it seems I get the spinning beachball all too often, but have plenty of ram and HD space. Even when opening JPEGS.
I am buying a macbook pro this w/e and was wondering what the best way to setup the new computer because I want to use it as an HD FCP editing station (on location), but from time to time use applications like aquisition and bittorrent which really seem to bog the system down. I assume not using migration assistant, and re-installing from scratch is a good idea.
Forgive what may be basic questions, but do I setup a partition initially on the internal drive (and have 2 system folders or something similar?) or will simply setting up different users to access only certain applications help? (I assume not).
Obviously a concern is the laptop drive is small 160GB 7200RPM but I can guess most of the time I will be running a GRAID for the video editing files, and bigger aperture library (I may have a small select library on the internal drive to show clients and friends "on the go")
I really appreciate any tips or suggestions and hope that my questions make sense. I realize I want the computer to "do it all" but can't afford it to be strictly an editing station, as I'll be selling the G5 to help pay for the macbook pro!
Much appreciated,

Understand that P2P software operates under the premise that you will have many connections to peers. Each network connection requires memory and CPU cycles to operate properly without timing out the connection or slowing down transfers. In fact, the faster the Internet connection and the more peers connected to your P2P application, the more resource intensive the P2P software will be. You will want to either close the P2P application or tweak it's settings so that it uses minimal bandwidth and resources while you are performing other tasks on your MBP. Try Azureus for torrents as it allows you to tweak settings very nicely.
Partitioning your hard drive will accomplish nothing in this case. Better to invest in an external FW800 drive for the improving performance while video editing or where you need additional storage.

SCEP date range reports change over time

Not really sure how to title this, but here is the scenario. I have altered a canned report to run the first Monday of every month and dump a Word file w/links into a folder. The alteration of this report is simply changing the end date to be -30 from today.
So I am getting a 30 day report of all computers that were infected. The report runs and looks to be accurate based on alerting I have setup. The problem comes when I take this report and start to drill down into the data using the links in the report. Let's
say my report shows a virus name with an infection count of 3. I can click on 3 and see a list of PCs that were infected....well not so much. If between the time the PC was infected and the time I look at the report, any of the 3 PCs were cleaned of the infection,
then they will not show up in the drilldown. So if a single PC was cleaned...the count still shows 3, but clicking on 3 only shows 2 computers now. This pretty much goes for any data on the main page.
So essentially the report is pretty useless to go back in time and see detailed info on the incidents since the status of every bit of info in that report has changed over time. I am not a SQL person, but I did have one of SQL team look at the database and
she can't see anywhere that she can pull archived data from. Any idea what direction I can point her in to get the type of reports I am looking for?

Yes, I know this is an old post, but I’m trying to clean them up. Did you solve this problem, if so what was the solution?
