  Okey, I finally found the problem. His Modem.

  Router is not able to get the IP address of the modem if the modem is started first and then I plug the internet cable to the router. But if I keep the router and modem connected and then reset the modem while keeping the router powered on, the router receives an IP address.

  And in both cases, if I connect the laptop with the modem directly, computer laptop can connect to the Internet.

  I bought a new router (WRT54G2) thinks that the problem is with the router, and I can reproduce the same behavior with both routers constantly.

  Make sure you modem is Motorola surf.

• Problem with internet connection 64-bit Windows Vista, unexplained intermittent failure.

  original title: PROBLEM CONNECTING WINDOWS VISTA 64 BIT INTERNET - UNEXPLAINED INTERMITTENT OUTAGES

  On HP a6542p PC with factory installed Windows Vista (64-bit), Vista operating system program does not take account of Internet broadband, which, in reality, a good connection.  for the first 2 years of operation, the PC internet connection worked well, but a year ago, he started this OFF intermittent / WE internet problem.  SOMETIMES, I can manage to temporarily restore the internet after running randomly across the machine diagnostic & installation programs available to the home screen, OR SOMETIMES also after running REGEDIT in the start (search) bar and watching the TCP/IP settings (do not change them, just watch), but the internet connection drops again after the machine is idle for a few minutes.  I get very tired of the exercise Dog & Pony to run through the different random procedures & hoping that something will work.  I tried the fix from Microsoft using a flashdrive D/L from the Windows site to my XP machine and tried a few manual corrections proposed on various websites, but nothing seems to work.  I have no HP manufacturer disk to reload the Vista operating system.  The connection is good, the cable is good, but Vista gives me contradictory information about the diagnosis, such as ERROR 815, and he tells me also a cable is disconnected (not true, the cable is plugged & good & works very well when the Vista connection is restored), while another diagnostic message indicates the internet connection is good, at the same time other messages say is not.   What can I do to fix this problem in Vista?  Personal e-mail is: * address email is removed from the privacy * -I will check that URL of Web site for the possible answer.    Thanks in advance.

  Imrand - Thanks for the tip, I tried it & it didn't work.  However, I found an update of the HP driver for the network card Realtek in my machine, & after d/l this new driver, the problem seems to be fixed.  The Web connection is still good after several cycles of closing & reboot.  I'm not sure, because with this HP Vista PC, I can never be sure of anything, but I think the problem might be due to the rotating system off the NETWORK adapter in sleep mode, & so not put on when waking up.  Diagnostics messages confused and contradictory pages of different screen Windows were of NO use, it looks like the internet connection was good (which it was), while the other would be at the same time say there is no connection due to the disconnection of the cable, while the other at the same time say that the DNS server broadband couldn't recognize my internet query.  Total BS of Vista, which has compounded the problem than he was.  I only am not surprised Microsoft abandoned the Vista operating system so fast, so many other users of Vista have similar internet connection problems.  The user friendly and very stable XP operating system I have on an old PC of Insignia is my favorite.  Microsoft had to quit with it, IMO.

  Thanks for your help, Cimarron

• Satellite C660 - no Internet connection after updating BIOS

  I am a novice user and have a Satellite C660 under warranty that I don't use for surfing the net and Ebay so I hope I can explain my problem!

  Toshiba bulletin board said that the need to update BIOS, so I followed the instructions but since then I have no internet connection, and cannot restore the connection that I lost all help Toshiba Bulletin Board today lost and none of the programs to sort the problems work - e.g.set assistants etc. I did not yet create rescue disks, but if I try to create them now I'll be able to restore to factory settings?

  Can someone tell me if it's a failure caused by the BIOS update or I would return laptop to John Lewis for repair? Thank you very much for reading this

  Hey Buddy,

  The default settings in the BIOS load after update? If this is not the case, go into the BIOS and load the default settings. You can enter the BIOS if you press F2 before Windows start and then press the F9 key to load defaults. Then save & exit the BIOS Setup.

  You can access the Internet now?
  You try to access the Internet with LAN or WLAN connection?

  Also check device manager if all devices are recognized correctly.

  > I did not yet create rescue disks, but if I try to create them now I'll be able to restore to factory settings?
  You can create the Toshiba Recovery disk every time. Just launch the pre-installed Toshiba Recovery Media Creator and follow the instructions on the screen. You need just a few blank DVDs to create the discs. Disks contain a factory image of settings which can be restored each time and how many times you want to so with these disks, you are on the safe side ;)

• Internet connection drops

  The OS is El Capitan 10.11.3 on both my MacBook Mid 2010 2.4 GHz Intel Core 2 Duo 8 GB 1067 MHz DDR & iMac 21.7 end 2012 2.9 GHz Intel Core i5 8 BG 1600 MHz DDR3, connection to the internet with the 5th generation Airport Extreme. The internet connection drops without model except that diagnosis shows a cable ethernet disconnected between the Airport Extreme and the ISP modem. I can install an older Airport Extreme I replaced about 4 years ago because there was no support for WPA security with the same Ethernet cable and the connection does not fall. I can also plug the MacBook with the power cord and connect via Ethernet. Is it possible that the Ethernet WAN port for the modem to ISP is down? The reason why I ask is that I install the older airport with the same ethernet cable. (I have other cat5 cables, but none of them are cross-cable as the cable provider ISP) I don't want to leave the network upward with the old airport because I have no security.  I price a new Airport Extreme and a cable crossed, but I'd feel better spending the money if I can be pretty sure that the 5th generation extreme is a failure. Anyone have any ideas?

  Some modems are more problematic that others... you must tell us the details.

  This modem you have, make and model please?

  You don't show us the summary for the AE, but if you run 7.6.4 firmware, it is less stable with some modems than previous 7.6.1 (this is why the old AE does not fall).

  Please firmware downgrade to the AE to 7.6.1. For this, hold down the option key while clicking on the version number of the existing firmware. A list... Select 7.6.1 (DO NOT USE 7.6.3. it is poor..).

  

  The latest version of AC AE is even worse... so I recommend you to buy a different brand of router... you can continue to use EI as WAP, as long as you take on their track, it should work ok.

• D7000 continually drops Internet connection

  My new D7000 abandons the Internet connection up to 15 times a day... Sometimes it will run for hours without problem and other times, falling from every 10-15 minutes

  He is recovering normally, but he sometimes needs to be restarted manually. As far as I can see, the WAN/Internet is configured correctly for my ISP (BT) because it works perfectly fine, until he falls
  (I'm not network guru, but know quite well what I do!)

  I have tried eaves values MTU of switching given that others had found that fixed things for them and just changed PPPoA to PPPoE encapsulation without success.

  I do not use the latest firmware (given that the update of my old router Netgera bricks it!), but downloaded it read to install manually the next step.

  any help please?

  V1.0.0.18_1.0.1 firmware version
  ISP: BT

  Basically, I discovered the following of my ISP:
  The initial problem was the result of a failure of the infrastructure - they replaced a wiring for my property
  The subsequent recurrence of symptoms has coincided with the upgrade of their Exchange works - they do not alert me of the upgrade until it was completed.

  Since then, the connection remained constant and reliable while being 4 times faster than originally.

  So, I think that the question is entirely the fault of my ISP.

• IP duplicated preventing internet connection

  My Windows XP does very well, no problems in offline mode. Any attempt to open ANY browser results in a release warning duplicate IP address. At this point, I can do without an internet connection. Pages will then expire or keep trying to load in a loop. How can I get rid of this address duplicate and will that fix my problem?

  The only thing I can think of that might cause a situation such as you describe requires some rather unlikely factors: a static IP address assigned improperly and an abnormally short DHCP lease duration or a too small range of IP assignment also coupled with abnormally short DHCP lease time.

  Another example failure router power Tricky described earlier, the most common IP duplicate addresses reason is that some devices on the network is configured to use an IP address (fixed) that is in the IP range used by the router to assign automatically the addresses.

  Administrators often configure devices that all users will want to join (like network printers) to have a static IP address, but the correct way to proceed is to choose an address outside the range of assignment.  For example, if the router automatically assigns IP addresses between 192.168.1.100 and 192.168.1.150, you re a printer with a static IP as 192.168.1.25.

  An IP address conflict caused by the use of a static IP address in the wrong range will arise when the router automatically assigns an IP address which is identical to the pre-assigned static IP address - and that should not happen in a timeframe of 30 minutes.  The only thing I can think is that the router has the term of lease defined DHCP to something a little more than 30 minutes.  It would be very unusual; the default on the routers DHCP lease time is 24 hours.

  On your computer, go to network connections, right click on your wireless network adapter, and then select Properties.  In the "Général" tab, select "Internet Protocol (TCP/IP)" and click on the properties button. The normal situation is to have the "obtain an IP address automatically" and "obtain a DNS server address automatically" selected.  That shows your configuration?

  You have all printers or other devices not computer connected to your network?  This does NOT include printers or other devices physically connected to a computer and then shared on the network.  If you have a network printer, use its controls on front panel to print a 'network status page' and see if it is configured to automatically obtain its IP address or if it uses a static IP address.

  There are also a few things to check in the configuration of the router, if you have access to it.  I like to watch

  • the range of IP addresses that the router uses (perhaps it has been initially implemented when there were fewer users and doesn't have a range of 10 addresses, so if the 12 you are trying to connect at the same time there will be a problem)
  • the term of lease of client
  • the table of the DHCP client (which will display all the devices connected to the router)

  If you identify the make and model of the router, I should be able to tell where to find this information.

  [EDIT]
  If you open a command prompt window and type
  ipconfig/all
  and then press ENTER, you can see when the DHCP lease was obtained and when it will expire ("Lease obtained" and "Expiry of the lease").  You will get something like this:

  d:\Users\LemP>ipconfig/all

• Problem to create the Internet connection sharing between Windows XP and Windows Vista.

  Original title: Internet connection sharing between Windows XP and Windows Vista.

  Hello

  Recently, I plugged a laptop running Windows XP to a desktop computer running Windows Vista using a standard Ethernet cable with the intention of use sharing of Internet connection. The notebook contains a wireless connection that I've routed to the office via the cable said.  While the initial phase of installation went well (I was too lazy to do it manually, so I just used the Wizard "Set up a home or small business network" Windows XP,) I had to turn off the host computer to install a program. When I tried to set up ICS again, I couldn't connect to the Internet by using ICS. After this failure, I tried to configure the properties of TC/IPv4 (IP, gateway by default, etc.) manually, but I still couldn't run.  I am able to access the shared host PC and client files. It seems to me that some service essential to the proper functioning of the ICS may be disabled in some way, but it's just speculation, as I have no evidence of such a service. Help would be most appreciated.

  Thank you

  FG-man

  I tried this before using a laptop to share internet with my 360.  problem is there was Nat on the router, and it is in contradiction with the ics.

  Anyway long story short I did some research on the Internet and discovered that if you're behind a router ICS will be confllict with her, as ICS also does routing. a much better option is to "bridge the conections ' on the laptop.

  http://www.Microsoft.com/resources/documentation/Windows/XP/all/proddocs/en-us/hnw_bridge_install.mspx?mfr=true

  If you go this route, you need to set a static ip address for the office,

  Either that or if you want to continue using ICS put the laptop in the DMZ in the router may help, but it will be less secure.

  Hope that this helped good luck
