• iOS iphone 10 does not connect to the DHCP wifi

  Updated IPhone 6 to 10 of IOS, and now the phone will not connect to my BT Home Hub 5.  All other devices will still be another phone that has 10 IOS.

  The phone recognizes the router password, puts a blue check mark against the connection, but no wifi signal appears and remains on 3G / 4G.

  If I look at the DHCP information on the phone, it's all white is wrong.

  I checked on the router and the phone does not display as connected.

• Can I have 2 Airport Extreme with running in a single wired network DHCP server

  Hello friends,

  Just a teenager from the windows world crawling as a child in the MAC world.

  I'm curious to know if we can have 2 extreme airport, acting as 2 DHCP servers in the same local network. I really doubt if it is possible, but still want to have Advisor by experts. I am considering a wired LAN. If possible, please help me understand how this can be done in detail.

  Thank you.

  In fact, you can. The key is to assign different DHCP scopes for each base station in the same IP address space.

  For example, you could assign the range 10.0.1.2 through 10.0.1.99 to a base station and have the other on: 10.0.1.100 via 10.0.1.200.

  You set the DHCP scope or range using AirPort Utility, as follows:

  • Run the AirPort Utility.
  • Select the base and then station, select change.
  • Select the network tab.
  • Select Network Options...
  • The range is set with the option "IPv4 DHCP Range".

  

  But the question would be why would you?

• Frequency of the Apple TV DHCP

  I see my Wired Apple TV 4 DHCP requests every minute. This doesn't seem fair.

  Hello. This seems to be a problem for a long time with the ATV ethernet interface, see AppleTV 3 floods DHCP when connected ethernet. I found myself with 4 ATV. My guess is that this may be due the router to 0 lease issue, which should be interpreted as 24 hours. Please add your report to Apple here https://www.apple.com/feedback/appletv.html.

• The settings DHCP Airport extreme & NAT - cannot change default of NAT IPs?

  Hello

  I'm trying to configure Airport extreme, the most convenient to use for our office.

  Our Office IP is 10.255.x.x

  When I'm trying to Setup DHCP and NAT, in NAT options, there is only 10.0.x.x, 172.16.x.x and 192.168.x.x

  How can I get NAT to have 10.255.x.x?

  Without the NAT settings, I can not get this Airport Extreme to assign valid IP addresses and so unnecessary

  Sorry, but Apple will only accept the 10.0.x.x addresses to be assigned by the AirPort Extreme.

• Time Capsule do not pick up address DHCP and cable modem...

  You just bought a Time Capsule and a couple of Airport Express. If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

  That being said, I tried to create a mobile network instead of pure wi - fi and am studying various behaviors that are not as expected when I rear hub to the Internet Time Capsule, but need to isolate and go 1 bit at a time... (it works not as well as suggest Apple instructions on homelessness of installation)...

  If:

  1. configuration of the modem cable shows that DHCP is 'ON' and supplied address range 192.168.0.x by 192.168.0.y,.

  2 Cable modem wireless is disabled,

  3 Time Capsule Wan is connected to the cable modem, Ethernet

  4 Time Capsule is configured to request its address IP, DHCP

  5. Airport Express is in Bridge mode and have addresses such as 10.x.y.z (appears to be from a Time capsule).

  6. safe as Time Capsule is set to be as DHCP and NAT

  7. There is NO other device in this configuration connected by Ethernet except the cable Modem and the Time Capsule.

  So, why is the IP address of the time Capsule 76.181.45.xyz? (The address is NOT in the range of the DHCP as described in the #1; it is not supposed to be?) ....

  Whence this address?

  A friend says this address puts the "other side" Time Capsule of the cable Modem, directly on the Net?... (Shouldn't worry?) ....

  If none of these devices are connected together via Ethernet, they seem to have set themselves up, and all is well.

  It's because you didn't have the devices connected via Ethernet before you set up the. Given that the installation utility saw a wireless connection, it is assumed that this was the way that you want to connect devices on your network at all times... so he put it this way.

  If you had an established connection Ethernet before you ran the installer, then the utility would have detected this connection and set up the airport to "expand using Ethernet", does not extend to assistance of wireless.

  (it works not as well as suggest Apple instructions on homelessness of installation)...

  If all goes well, you don't talk about this document... Wi - Fi base stations: extend the reach of your network wireless by adding additional base stations Wi - Fi - Apple Suppo... .. Since the 'how' information in this article is at least 4 years late, bear little resemblance to the latest version of AirPort Utility and some of the information are simply not true.  This document if trash is what you... He'll probably do more harm than good with regard to the details of setting.  The article is OK for basic general information, however.

  6. safe as Time Capsule is set to be as DHCP and NAT

  It should not be if your modem is a modem/router "" or type 'bridge' of the device which is also DHCP and NAT services. The fact that you have disabled the wireless on the device confirms that it is both a modem AND a router. That being the case, then you have two devices that both struggling among themselves to try to control the same network... AND do you also have a network error called Double NAT... something you don't want.

  Probably the best at everything again and provide us with the number of brand and model of your "modem", that we can confirm what it is that you have, then the correctly configured time Capsule to work with this device. Once the time Capsule is set up correctly, it will be easy to put in place the other airports.

• Garage double NAT & DHCP - bridge Possible issue error

  Help...

  So it's my game on a yacht...

  I have a MacMini (run bootcamp Windows 7 Pro), so actually it's a PC.

  • I use internal WiFi adapter of the MacMini to get my internet connection of various different Marina I could stay in
  • I then share the connection with the internal LAN adapter WiFi adapter WiFi
  • This allows me to share the WiFi port with other devices on the yacht

  Then I have an AirPort Extreme-

  • I then run an Ethernet on the MacMini Port CAT6 cable
  • on port WAN on AirPort Extreme
  • AirPort Extreme now has an internet connection (from the marina, WiFi)
  • I then activated the WiFi on AirPort Extreme to create a WiFi network on the yacht
  • and it gets its internet connection from the WAN port, which comes in turn the MacMini, which in turn comes from the Marina WiFi

  Connected to the AirPort Extreme are-

  -iPhones, iPads, MacBook, Apple TV, Smart TV, etc etc.

  -Some devices are connected using the LAN ports and AirPort Extreme cable

  -Some devices are connected by WiFi using WiFi airports

  I want DHCP to be handled by the AirPort Extreme-, mode I set as "DHCP and NAT".

  What is the problem-

  • AirPort Extreme shows an error
  • "double NAT and DHCP.
  • and suggested I turn it in Bridge mode
  • but I don't want to do that

  Any thoughts?

  Concerning

  Tim

  Would help if we could get the exact message you see.  You will probably need to change the DHCP-range on the AirPort Extreme to a different value, and then use the option 'Ignore' the Double NAT then the airport will show a green light.

  You will have to live with the Double NAT if you want AirPort Extreme to act as a remote router that provides a private network.

• Satellite C870-1J6 wired LAN DHCP problems

  Hi all

  Here, I have a new laptop C870-1J6, which makes my life miserable. It won't start not reliable PXE, and the network card also does not start in Windows.

  On a cold start the PXE boot Gets an address dhcp fine most of the time, but a warm reboot fails most of the time.
  In windows this NIC also does not start. After five to ten minutes, he finally gets an address from the DHCP server. Rest of the network works fine.

  No points for guessing the manufacturer of the network card, of course, there a realtek :-(
  "RTL8102E/RTL8101E PCI Express Fast Ethernet controller.
  PCI ven: 10EC, dev: 8136

  None of the solutions, or can send Toshiba somehow? because I don't think I can do a lot on the PXE problem myself.

  At first, I have to say that I m really wondering why you have problems of LAN under Windows.
  Have you noticed these LAN issues from the first day of use?
  Are you using the original pre-installed OS that you got with your laptop or a facility clean or even company?

  Maybe stupid question, but I assume that LAN is set as first boot device, right?

• Migrate server DHCP static leases

  Hello

  We currently use an old Mac Pro as a DHCP server, use the latest version of server of El Capitan. Now, we want to copy all the static DHCP leases we have implemented (approximately 120 static leases), so that we can put them on another Mac mini, this time takes up half of the leases for a different subnet.

  I know that the DHCP leases, temporary positions, are saved in a file that you can delete to erase the leases, but I have not found where static leases are saved. I know that you can change in the Directory Manager application, but I need to export them somehow, so that we can easily migrate. A Time Machine backup is not an option.

  Thanks in advance!

  See you soon

  Apple's DHCP server configuration file is /etc/bootpd.plist

  The file you're looking for is/etc/bootptab , but it is also possible to set static IP cards in Open Directory itself in the computerssection. If a card is defined in/etc/bootptab it takes precedence over the setting in the Open Directory.

  You can perform the following operations in Terminal.app to get more information

  Man bootpd

  bootptab man

  The file that contains the list of active leases is/var/db/dhcpd_leases

  It's a little ironic that Apple uses the name dhcpd_leases dhcpd is a different program from the competing DHCP server to the bootpd use of Apple program. Bootpd Apple is highly personalized on the original version of the open source to add for example the NetBoot support.

• Satellite A200-22I - DHCP and SENSE of the problems when you start Windows Vista

  When I started my laptop yesterday, I noticed it was going quite slowly, more there was a message saying that windows could not connect to a specified service.

  As a result my firewall was off tour and I can t connect to the internet. I tried to turn on the firewall, but I couldn't... and today, I tried another connection to inalambric, but I couldn't connect to the internet.

  I checked the registry of the solution and the problem and found it was something related to DHCP and sense.

  But really, I don - t know what causes this problem...

  I searched other forums where people have had the same problem but I could t find any solution apart from reinstalling Vista...

  Can someone help me? Help will be very appreciated!

  Thank you

  Hello

  What do you mean with SENSE? I never heard tell about.

  I put t know what are the causes of the problem too but did you look in Event Viewer? Sometimes, it's really useful.
  If you have a network problem, you must update the driver WLAN or LAN (depending on whether you are using). You can find it on the Toshiba site:

  It would be interesting to know what Windows service, you mean. View more information on this error.

• Satellite Pro L300 - 12 H did not get the IP address of the DHCP router via cable

  My Vista Premium SP1 laptop is connected via a wireless connection to a modem/router ADSL Buffalo WBMR-G54 model that works very well. However, I tried the other day to connect the NIC via a RJ45 cable to the router and it won't work! I get the message "limited connectivity" and an IP of 169.254.xxx.xxx that suggests he does not get an IP address from the router.

  I was on various websites and tried all sorts of things as uncheck ipv6 on the properties of LAN card, put off the power of the DHCP Broadcast flag in the registry (according to the number of micrsoft) etc but nothing works.

  Anyone have any suggestions to make it work?
  NB: I took the laptop in work and plugged into the Windows 2003 Server network and got a DHCP IP immediately!

• another computer on your network is using your computer - Hack suspicion - ip address through DHCP lease renewal. Help, please

  Hello fellow Mac users...

  Today, while using, Firefox A message appeared on my screen: another computer on your network is using the ip address of your computer.

  Now, I am 100% sure that my phone was turned off when it happened. And I have a password on my wifi connection.

  I panicked because no one should have access to my network or my IP address. Immediately, I turned off my modem and turned off the wifi on my mac.

  Later, I went to renew the DHCP lease.

  My question is this:

  Could it be, in theory, based on the message system I (another computer on your network is using the ip address of your computer) the IP address was stolen (for lack of a better word) by a remote user, which is not in my physical neighborhood that is resident in another city or even country?

  If so, then I did the right thing by closing my Modem? And later on the DHCP lease renewal? About 20-30 minutes past until what I actually renewed the DHCP lease. It, in theory, could have too late to do (assuming that a malicious user has chosen to masquerade himself with my IP address)?

  Thank you all very much!

• No DHCP / wrong IP of open networks - Portege M300

  Hello

  IM using a Portege M300 with a built-in wlan card. I have w2k with sp 4 installed. My problem is that I can connect very often to open wlan points, but most of the time that my computer can't pick the right IP address or dhcp server. I've experienced this in many different places and now Im seeing this again in a network home. WEP is disabled, so is mac filtering and all other computers on the wireless network work just fine, but not my laptop. In this case, I checked the router and the ip address range is in the range 192, but my laptop contains an ip address that begins with 169.

  Does anyone have an idea what could be my problem?

  Sincerely

  Johan

  Hi Johan

  Believe me on this path is not easy to tell exactly what is happening in your case. The fact is that a lot of people have similar problems. Not because of Toshiba for laptop or same Portege M300, but because of the wireless card. It is known that card WiFi Intel 2200 B/g do some connection problems.

  Please check this page http://support.intel.com/support/wireless/wlan/pro2200bg/ Intel

• Satellite Pro C650 can't find our DHCP server

  Hello

  We just recived 8 new Satellite Pro C650 and care about their image.
  When connect us to our network via a cable and boot on LAN of the laptop can not find our DHCP server and so of does not obtain an IP address.

  If we connect to an another laptop\workstation in the same Manor, it works very well.

  All the settings are correct in the BIOS.

  Any ideas.

  Hello

  First of all, you should check if the settings of TCP/IP to connect to the local network.
  Network-> properties-> LAN (local area) connections-> TCP/IP-> properties

  Here, you should check if the options for the IP address, DNS are set to obtain automatically.
  In the advanced settings of TCP/IP in IP settings tab active DHCP must be visible.

  In addition, please check if all firewalls do not prevent the laptop to connect to the local network.

• Time Warner failure: replace BRIDGE MODE DHCP/NAT!

  If I woke up this morning to find that my Time Warner Cable internet has exploded the line last night. According to my AirPort Utility application, my Airport was functioning normally, but it was not connected to the Internet. So I restarted the thought of the airport that could solve. Not only it does not solve my problem, it made it worse:

  Now, he pointed out that the AirPort base station has a private IP address and suggest that change my Airport to use DHCP and NAT mode.

  Now keep in mind, it has been working perfectly for months with the current settings. Suddenly, he must be in Bridge mode after reboot it?

  I had to leave for work so I didn't have the time to reset the modem from Time Warner Cable. However, I suppose that I should not change the settings on my AirPort at the moment since it worked perfectly before?

  I have the current model AirPort Extreme and configured automatically, after several attempts of frustrating with the same modem from Time Warner Cable, which I am currently using, of course it takes hours to acquire a signal of Time Warner Cable.  It has been working perfectly since.

  This should resolve on its own once the cable connection is restored, or is it that this means that I have to completely reset my AirPort Extreme and implemented from scratch with the cable modem I did originally?

  It would help us if you could provide the serial number and model of your modem.

  IF... the modem normally gives you a public IP... so the parameter DHCP and NAT on the most convenient airport would be correct.

  IF... the modem... which normally provides a public IP address was not reset, then it could actually send a 'private' IP address... probably something in the 192.168.x.x range... that is not correct.

  Turning off the modem by pulling on the power cord to the back of the unit

  Unplug the co - ax cable and Ethernet cable

  Let off for at least 30 minutes the modem... 60 would be better.

  Turning off AirPort Extreme as well

  After turn off modem, reconnect things

  Start the modem and let it run for at least 10 minutes by itself

  Then, turn on the AirPort Extreme.
