WiFi loses connection intermittently and the erasure of the arp arranges

This has been asked before many times, but none of the above worked for me so far.

I have a MacBook Pro with El Capitan on it. From time to time, usually 5 to 10 minutes,

my connection drops and I can browse the internet. As:

4 bytes of 8.8.8.8: icmp_seq = 7646 ttl = 53 time = 13,091 ms

64 bytes of 8.8.8.8: icmp_seq = 7647 ttl = 53 time = 17,035 ms

64 bytes of 8.8.8.8: icmp_seq = 7648 ttl = 53 time = ms 13,716

Request timeout for icmp_seq 7649

Request timeout for icmp_seq 7650

Request timeout for icmp_seq 7651

Request timeout for icmp_seq 7652

Request timeout for icmp_seq 7653

Request timeout for icmp_seq 7654

Shooting, then turn on the WiFi will fix the problem, but I tried to limit the problem

and I discovered that deleting IP of the route in the arp table will also fix connectivity

immediately:

$ sudo arp d 192.168.0.1

Request timeout for icmp_seq 7718

Request timeout for icmp_seq 7719

Request timeout for icmp_seq 7720

64 bytes of 8.8.8.8: icmp_seq = 7721 ttl = 53 time = 10,947 ms

64 bytes of 8.8.8.8: icmp_seq = 7722 ttl = time 53 = 11,966 ms

64 bytes of 8.8.8.8: icmp_seq = 7723 ttl = 53 time = 12,576 ms

64 bytes of 8.8.8.8: icmp_seq = 7724 ttl = time 53 = 11,058 ms

64 bytes of 8.8.8.8: icmp_seq = 7725 ttl = 53 time = 15,173 ms

Deactivation of unicast arp has NO had no effect either:

$ sudo sysctl-w net.link.ether.inet.arp_unicast_lim = 0

Notes:

-J' have two MacBook Pro at home. Other works without problem.

-My phone and other devices work also with the same router with no problems.

-The problematic MacBook works with other WiFi networks without any problem.

What could be the problem?

Yes, clear arp fix it. Very familiar with it.

I had this problem for 2 years and more than 2 or 3 MacBooks, on El Capitan, Yosemite, and Mavericks.   I Googled it every 1-2 years months.  I captured packets and tested several access points... The best fix so far... is the arp compensation, and I have the automated at the moment:

in a terminal:

While true; make sudo arp - da; sleep 2; fact

When the window is open, every 2 seconds, my arp table gets undervalued... and if I lose connectivity, the maximum cut is 1 to 2 seconds.

I noticed that in some places, I don't have the problem... its as if my laptop reacts badly to some other customers on the same WIFI network.  This question makes me crazy, and I can't imagine how was such years.  If I don't fix it manually, I find myself for 30-120 seconds every few minutes.

  • My PC loses connection local and Internet after waking from sleep/hybernation.

    My PC loses connection local and Internet after wakes up from sleep/hybernation. The problem is solved by resetting the network card, but it is frustrating to have repeated resets every time the system in place to wake up. I am looking for a patch, I searched all the support sites and forums where there are similar problems that have been offered to different patches over time, but each of them has failed.

    Hello

    Check the updated drivers for the NETWORK card and WiFi.

    Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
    version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
    Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  • Great printer Officejet 7500 a Format to connect intermittently to the computer via the wireless network

    I have a portable printer Officejet 7500 has recently purchased that I would use wireless.  I have an Apple wireless router and am running Windows 7 on my computer.  The printer and computers individually connect to the network, and there is no problem with the router.  The problem is with the connection between the computer and the printer.  I can print things from my computer by sending a file to the printer, but sometimes it works through printing directly from the software.  I tried to scan my computer and the printer, but get the same error at the same time that there is no communication between the printer and the computer.  I suspect that it is a firewall problem, but do not know how to change the settings to allow this communication to occur.  I have the windows firewall and advanced software protective system, but have disabled the windows shield in this software.  Help?

    First of all, download and run this utility:http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=us&lc=en&jumpid=ex_r4155/hho/ipg/ccdoc/printer_diag/&lang=en&softwareitem=oj-106151-2

    What did he say?

    Just to be clear, that the 7500 a is connected to the Airport via radio, correct (not USB)?

    If so, we will define an external static IP and DNS address for the printer:

    -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
    -Enter the IP address in a browser to reveal the internal settings of the printer.
    -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
    -On this screen, you want to set a manual IP address. You must assign an IP address outside the range that the router sets automatically (called the DHCP range). Yours is 10.0.1.2 a.200.  We use 10.0.1.220 for your printer.
    -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
    -Enter the IP of your router (on the Page of the Network Config) for the gateway.
    -Enter for the first DNS 8.8.8.8 and 8.8.4.4 for second DNS. It's Google DNS. You can choose a different external DNS if you wish.
    -Click 'apply '.

    Now, stop the router and printer, start the router, wait, and then start printing.

    I setup a new native admin for the planning application and then update a source of app planning data, restart planning and test to see if you get the same question.

    Also, I've seen questions when you have a username called Administrator in the announcement and one in the native user directory, if it isn't the cause to ensure that the user admin, excluded from the configuration of the AD

  • Satellite T110-11U: WLan connection dropped and very slow performance

    Hi people,

    I use a Satellite T110-11U running windows 7 Home premium.

    After having initially was very satisfied with its use, it now becomes more and more frustrating to use with wifi, with connections dropped and very slow performance.

    I have updated the BIOS and think I have updated all drivers wirelss, but could be the problem. It seems that wireless, software of management is at fault because the networks are detected, but not clinging.

    Any suggestion or tips to try will help save my sanity!

    Thanks for your help.

    John

    > have updated the BIOS and think I have updated all drivers wirelss, but could be the problem.
    If you need to make sure that you use the latest WLan driver.
    The driver can be downloaded here:
    http://APS2.toshiba-tro.de/WLAN/

    The laptop uses the Realtek RTL8191SE of WLan card.
    Please also reset the settings of the Wlan router. I had a lot of problems with my WLan and after the reset of the router, performance problems disappeared.

  • OfficeJet Pro 8600 all-in-One connected as network printer loses connection

    In December 2011, I bought a HP Officejet Pro 8600 all-in-One to replace an Officejet 6500 as my network printer home. The 6500 worked very well on my cable, but his screen did not, I tried some of the features offered by the 8600 and I got a good price on a new warehouse of BJ. I have the 8600 connected via ethernet (not wireless), with a static IP address. All my computers on the network are running Windows XP Pro SP3 and are up-to-date with Microsoft updates. However, from one day to the next my 8600 will lose connectivity scan (Scan of the computer shows it as being disabled on all my computers at the same time, and I can't reconnect), and if I do not have anything he'll (as in a few hours) also lose connectivity impression. The only way to restore connectivity is to uninstall the HP Officejet Pro 8600 device software basis of all computers, and then reinstall the printer. I had a phone conversation and two debates with HP Technical Support; They suggested that the problem is in the firewall on the computers (but if that were the case I don't think that the loss of connectivity would occur on all computers at the same time), the IP address setting (doesn't make sense) and the printer driver is not not the latest version. I tried all the suggestions, and none of them have solved the problem. The last counselor "has raised the issue to the next level", which proved to be a Manager with no technical expertise and his only suggestion was that I have to return the printer to the merchant. I think the problem is the firmware in the printer (which, according to the 'update' on the printer option, is the latest version). Any other suggestions or experience?

    After a lot of research and find the settings that I did not know that Windows XP offered, I found that the following appear to have solved the problem I've known - at least the printer is now operational for more than 48 hours without losing printing or scan connection. Here are the steps I used:

    1. Start Control Panel  connections network and Internet

    2. Choose "network connections."

    3. Right click on "connect to the Local network.

    4. Choose "Properties".

    5. In the top window is the name of the Ethernet computer connection port, select "Configure" next to this window

    6. Select the tab labeled 'Power Management'

    7. Uncheck the box "allow the computer to turn off this device to save power".

    8. Select the "Advanced" tab

    9. Select the entry "power saving Mode".

    10. If this entry is set to change 'On' to 'Off '.

    11. Select 'OK', and then close the windows that were opened
