• Model WRT1900AC consistent, persistent of the GALs of WiFi

  Hello, I noticed that my new brand WRT1900AC a pattern consistent and persistent lag on WiFi. I tried different placements, antena positions, restores, put it next to the laptop - pattern remains the same no matter what happens. Software InSSIDer shows no conflict on my 5 GHz N network. Please take a look at this model: http://pastebin.com/LAaNFGuc

  The model is: every minute, or so there is a serious discrepancy (100 to 200 ms) and then he comes back to 1ms, then after a minute latency period and the cycle repeats indefinitely. It's very frustrating because I tested my old cheap, compact WiFi router and it gives me 1 compatible MS all the time. I have installed latest firmware and have exhausted my options to diagnose me. Someone have any suggestions, would someone run same test, and see if the results are the same, support could be something on this subject? My blind guess is that every minute or so the router is something very CPU expensive, maybe recalibrate and it takes 300 to 400 ms so he could return to the treatment of packets. Thank you for any help or suggestion.

  Hello everyone, thank you for your messages. I tried 2.4 Ghz and 5 GHz with the same result. But I found the cause and solution.

   

  The cause:

  Drivers Intel for Windows 8 and 8.1 for their Centrino WiFi network cards (thinkpads have) have experienced a bug that causes scanning to broadcast SSID significant lag on the network card. This only concerns cards Intel Centrino, other maps do not suffer from this.

  Solution:

  Change the value of Windows for WiFi registry do not search for new networks while you are connected to one. The solution works and is posted on the forums of Lenovo here: https://forums.lenovo.com/t5/Windows-8-and-8-1-Knowledge-Base/Debugging-latency-spikes-and-lag-on-ce...

  It worked for me, now I get 1 compatible MS all the time.

• Icmp6 seems to ignore the access control list

  Hi all

  I suspect this might be a case of staring at the screen for too long, but nevertheless, I'm here.

  I'm testing an IPv6 deployment between my ISP and an ASA 5505, 9.1 (5) mode routed, and initially, everything looks good.  Can I ping6 both of the SAA in the real world and backward.  BTW. the ASA is already running quite fortunately NAT for IPv4 with ACL and everything, no problem.

  The only problem is that, according to my interpretation of the doco, I shouldn't be able to ping to the ASA from outside as I not ACL IPv6 in place.  Therefore, the default deny rule should apply and she's dropping packets.

  Furthermore, if I add a specific authorization for ICMP6 rule there is no count of packages registered against it.

  This leads me to suspect that IPv6 packets are intercepted earlier in the chain and were allowed through, but where?

  Thanks in advance,
  -pete

  PS: don't know if this should be a cross published in IPv6 transition...

  Pete,

  I think this doc is mention that ACL if you want to send traffic _to_ ASA.

  http://www.Cisco.com/c/en/us/TD/docs/security/ASA/asa91/configuration/GE...

  If you're curious about treatment:

  -packet - trace - unreliable in some cases

  -capture traffic with "command option and"trace"capture. There are some examples of TAC on how to do it.

• Lose packets using winpcap

  Hello

  I'm working on a LabVIEW application to view our telemetry data.
  These data are sent over ethernet using UDP and has a payload of 1 332 bytes. The framerate is 6720 packets per second.

  To work with this data rate I put sockets UDP receive exactly the size of the packets multiplied with the payload buffer ( http://digital.ni.com/public.nsf/allkb/D5AC7E8AE545322D8625730100604F2D ). Increasing or decreasing the buffer will lead to errors and one or several packages will be lost.

  However, I'm still a few packages.

  Now, I tried to use the Ethernet Packet Sniffer example ( http://zone.ni.com/devzone/cda/epd/p/id/2660 ) and changed the Example.vi to verify our internal counter of packets in each package. I was happy to see that no packets were lost! But, after adding the VIs Sniffer to my request for loss of massive packets occurs. :-(

  Then, I moved the acquisition work in the wrapper DLL. The function below is called with a 1 d of pre-initalized channels table. The allocation of memory in this way is done in LabVIEW.

  / * LabVIEW created typedefs * /.
  typedef struct {}
  dimSize of Int32;
  LStrHandle LString [1];
  } TD1;
  typedef TD1 * TD1Hdl;

  EXTERNC EXPORT int32 lvwpcap_read_n_packets (uInt32 pcap,
  uInt32 * tv_sec;
  uInt32 * tv_usec;
  uInt32 * capture_len,.
  TD1Hdl capture_data)
  {
  struct pcap_pkthdr * header;
  const u_char * data;
  Int32 array_size, string_size, i.;
  Int32 retval = 1;
  Int32 errors.
  LStrHandle TempString;

  Errors = 0;
  ARRAY_SIZE = (* capture_data)-> dimSize;
  TempString = (* capture_data)-> LString [0];
  string_size = (* TempString)-> cnt;

  * tv_sec = array_size;
  * tv_usec = string_size;

  for (i = 0; i< array_size;="" ++i)="">

  retval = pcap_next_ex ((pcap_t *) OCAP & header, &data);)

  If (retval > 0) {}
  * tv_sec = header-> ts.tv_sec;
  * tv_usec = header-> ts.tv_usec;
  * capture_len = header-> Caron;

  TempString = (* capture_data)-> LString [i];

  avoid the expensive memory allocation.  assumes that the string is at least 64K
  (or whatever it is we set the size max with our init call.
  memcpy (LStrBuf(*TempString), data, header-> Caron);
  }
  else {}
  i-- ; In the case of timeout right pointer to avoid skipping entries in the table
  Errors ++;
  If (error > = array_size) {}
  Returns - 1;
  }
  }
  }

  * tv_usec = errors;
  Return retval;
  return errors;
  }

  The problem: I have also now lose packets! Not on every call to this function, but in a way regularly (in on every third call).
  What am I, am I doing wrong to acquire say 800 packages at once without losing a single?

  Is there anyone with the same problems using winpcap?

  UDP packets are sent by our material and the PC is connected directly via a crossover cable.
  I'm using LabVIEW 8.5 and WinPcap 4.1.2.

  Thanks in advance for your reply,

  Thilo

  Paul has best suggestion at this point; loops parallel, combined with queues to create an architecture of producer/consumer.

  For an example, see here.

  In the upper loop of the example, you will place a UDP, or even reading your SUB_Collect_Data.vi. The output data would be placed in the queue.

  The lower loop could extract something (your cluster TC Stream) and perform the FFT and UI updates.

  The queue allows the decoupling of processing data acquisition. The top loop withdrew the UDP connection data without stopping to process or display data. The lower loop removed data out of your queue as fast it can run and perform your presentation FFT/AC.

  Note that a queue is up to be exhausted of your system's memory. Using a queue does not relieve you of the treatment of data in some time, but it allows you to take greater advantage of the capabilities of LabVIEW parallel / multiprocessor.

  Search the knowledge base and of producer/consumer forums and you will find many examples...

• How the ACL runs fragmented packets?

  Hello

  I'm looking for documentation on how the acl managing fragmented packets. Let's say I have the following in my access switch:

  class-map correspondence-everything MyACL1

  match the name of group-access MyACL1

  class-map correspondence-everything MyACL2

  match the name of group-access MyACL2

  class-map correspondence-everything MyACL3

  match the name of group-access MyACL3

  class-map correspondence-everything MyACL4

  match the name of group-access MyACL4

  class-map correspondence-everything MyACL5

  match the name of group-access MyACL5

  class-map correspondence-everything MyACL6

  match the name of group-access MyACL6

  In what order the fragmented incomming package will be checked by my class-card rules? It is sequential? I doubt it.

  Concerning

  He travels class-cards until there is a match, and it applies to this category

• The most convenient airport in Bridge mode lose packets

  Hi all.

  I have an airport extreme with the version of firmware 7.7.7 (later at the time of this announcement). My modem ISP settings are blocked and it is already fixed to make routing/DHCP/Nat, so I use my airport extreme in Bridge mode to avoid the double NAT (it connects connects to the ISP with DHCP router).

  Both the ISP modem/router and Airport extreme are creating two different 'wifi networks", which belong to the same network (192.168.0.0).

  I can enter each of this Wifi network, obtain an IP address in both cases and start using the internet.

  However, when I use it on my ISP router, everything works perfectly, however, when I use it on the airport network, it fails from time to time.

  If I start ping an external IP address (e.g.: 8.8.8.8), I've never lost a packet on the network of the ISP router, but I lose packets often on the airport extreme network.

  Also, if I ping the ISP of the airport extreme network router I lose packets from time to time. Sometimes also vice versa. I never lose packets when ping the router whose network providing I'm connected to.

  All the settings on the airport extreme values by default (except that I created an additional network of 5 GHz).

  Can you give us some advice as how to solve the problem? I read somewhere that disable ipv6 connection sharing could solve the problem, but it didn't. Thanks in advance

  If you have the Ethernet cable from your ISP router that is connected to the "O" on the AirPort Extreme WAN port, unplug the cable and plug it into one of the three ports LAN <>- on the airport to see if this will help with the issue.

  However, if you have the Ethernet cable from the ISP router already connected to one of the LAN <>- port on the AirPort Extreme, then you'll need to reset the AirPort Extreme back to default settings and then set up again.

  If you have any further questions, the Airport extreme is defective and must be replaced.

• Log treatment missing in FCPX?

  Hi all

  Just got a new MacBook Pro (15 inch, mid-2015 retina) and FCPX (10.2.3) is installed. After you import a few sequences of Arri Alexa 2 K, I found that the newspaper treatment option has been completely absent from the video Info-> display settings. Display of the metadata edition has no effect; the log processing area is verified, but does nothing. All other metadata options work fine and appear / disappear as they should when we checked and unchecked boxes. Only newspaper treatment fails.

  The fact that this option is inexplicably missing is quite frustrating. My other, slightly older MacBook also runs FCPX 10.2.3 but did not have this problem. When the same view of the clips on this computer, I am able to switch between power for the treatment of newspapers without problem.

  The possible explanations for this? Help would be greatly appreciated.

  Looks like you have done this, but here are some steps in the case where:

  Select change the display of the metadata.

  

  It appears, then select the video properties to quickly find your journal of treatment:

  

  Then check the Change Log:

  

  Click the OK button to save.

  If that's what you already have and it doesn't work.

  Hold down Option-command at the beginning of FCP X and reset the preferences.

• Advise on the treatment of raw cr2 files

  Nice day!

  I'm new shooting from raw files and are in need of some good advice & counsel to treat you in Aperture.

  My camera canon 6 d, my version of opening is 3.6.

  I import my photos to the Aperture library with selection of predefined effect 'auto-enhance', some how when I load the individual photo to see, it seems to 'do' my pictures 'dark' as compare when I saw from my camera.

  I import my image to other raw by this time deselect the "settled", same thing happens when I see the photos in Aperture.

  My questions:

  1 is this normal for the treatment of the raw files? Which means I have to make a few exposure & contrast adjustment?

  2 or is there any tips that I can learn from your part in the treatment of raw with opening files?

  3. the pictures are perfect when I saw from my camera, however, it seems somehow bit 'out' when I load in Aperture.

  Thanks to advanced tips & advise sharing.

  See you soon!

  You have a raw treatment defined in the default settings panel for your camera? Choose a raw image and leave the default value

• compressor does not reach 28 seconds in treatment

  After sending file fcpx to the compressor, it will fail at 28 seconds in treatment. In the same event fcpx I have 2 projects ongoing 1 to process completion ok but 1 fails after 28 seconds. I hope someone can help. My computer knowledge is limited. While now the key option + cmd and the compressor still does not work, I opened fcpx. Recently, I have completed other major projects without problem.

  I also did the cmd + SHIFT + G and follow-up library / application support / compressor / history / delete a recent entry to delete the history, it has not helped I also did command + SHIFT + G / home lib / users / shared / library / Application Support / Apple Qmaster / storage / delete files in the V4 folder, but the folder was empty

• Why are the files "stuck" on the treatment of file?

  I downloaded two television shows that show the entire file is downloaded [i.e. 1.40 1.40 GB GB]. They each have the statement "processing file" and blocked at this point for days.  I tried to stop the process.  Each episode is then listed for download again.  I begin a new download, and the results are always the same - stuck to the processing of the file.

  Does anyone know how to complete the treatment, so the episode joined his brothers and sisters?

• Fixing glare treatment

  Good evening. I have a problem with my anti-glare treatment, which has started to wear off. I bought my Mac Pro retina 15 about three years in the United States, so I'm out of warranty. Also due to some personal issues I have even my old guaranteed. I would like to know if it is possible to fix it for free in London? And how much time this procedure will last while I'm in London just for a few days?

  Also is it possible to prevent this lining, or at least slow down this process?

  You are out of warranty. Period. The fix to warn or damaged anti-glare treatment is a replacement of the screen. It won't be free, and the Apple Store in London can be more accurate on the replacement cost.

  The only "free" is an introspective examination of what you use to clean your screen. If this isn't a cloth Microfiber wet (or dry), distilled water, then you're doing it wrong.

• M40-154 satellite WLAN interface does not send a single packet

  Hello

  I own a Toshiba M40-154 with built-in Intel PRO/Wireless 2200BG Network Chipset. I am running Windows XP Professional Service Pack 2. 9.0.1.9 driver version.

  The Windows hardware Manager shows no conflict about resources memory, interruptions or anything else, just said me eth. would be nice (.. .and Yes, I changed the WLAN switch in front of the box to 'on')

  I configured both Wireless-Lan, once using the Toshiba and Windows XP itself once.

  Wireless networks are recognized, but I can't make any connection. It seems kind of strange to me, because when sniffing Interface with Ethereal, lie, not a single packet is sent by my WLAN interface. I checked all the configuration on another laptop with the same chipset and just works well.

  After the first installation of Win XP, I had a similar problem with my Marvel Yukon LAN interface. He comes to recognize connectivity (even LED a cover connectivity) but not sent or received a single package. I could only get rid of this feature by installing the device drivers located sequentially.

  When you run the diagnostic tool for Toshiba it tells me just the network test "fails". I m really get angry with this tool to completely unnecessary IMHO, because she neither doesn´t made the distinction between my work correctly Marvel Yukon LAN and WIFI, nor give me any hint, what could be the problem...

  Anyone with similar problems or able to give me a clue?

  [Edited by: admin August 10 05 19:33]

  Hello

  I'm really confused. Last week I set up the Satellite M40 and WLAN network by a friend of mine. His unit is pre-installed with recovery DVDs and everything works fine.

  Have you had problems at the beginning or just after installing WXP professional? I put t know how you installed the operating system, but I hope that you used the instructions to facilities provided by Toshiba. The order of the facilities is very important.

  If the WIFI network is visible in my opinion there must be a problem with the WLAN settings. Your WLAN is locked with a WEP key? Try to establish a connection without restriction.

  I hope that your access point is just configured and type of PPPoE. In this case the IP address must be the value automatically.

  Sorry, but on this path, it is really not easy to say what may be the problem.

  Good bye

• Satellite L30-115 - deleted TCP and FTP packets

  Hi all

  I have a Toshiba Satellite L30-115 and a DSL connection. I have a problem with my laptop running Win XP SP2 with AVG anti-virus.

  TCP and FTP packets are systematically deleted by Firewall setting or my system. I tried these tools that rewrite the registry entries for the TCP/IP protocol in Windows XP, but nothing seems to fix. Everything that affects the TCP fails systematically:
  [My browser tells me that the connection was reset during any process, AVG says automatic updates failure but 1] I always got ping www.yahoo.fr and strangest of all, Skype connects properly (likely because it uses another protocol and also because it is in the exception list from my firewall).
  Here is that I only have the native Win XP firewall and not others (license AVG, I've got is only to protect web, mail and virus).

  Another thing is that the problem persists even when I turn off the firewall or if I play around with the settings.

  Help, please.
