MacBook :: Using Wireless Shenanigans - Changing Back To Dhcp?
Jul 28, 2009
I recently got a white macbook while i am deployed in iraq, and our wireless signal here kinda blows, but at least it works. The only issue i have, seems to be that when i am connected to an access point, my macbook will randomly loose signal, and i end up having to go into the airport preferences, change from DHCP to BOOTp, and it will refresh, then come back on. If it looses signal again, i just change it back to DHCP, and then it works again.
I have an additional question about the Airport Express. I am interested in buying one but don't want to commit until I get a few questions answered.
1. I own a D-link wired router and a d-link wireless router. I have been tempted to buy the express, hook it into my wired router and run wireless off of the apple. I want the express so I can run itunes on my stereo from anywhere in the house.
Would there be any advantages to me using the wireless router in conjunction with the airport express instead?2. I am interested in the DHCP comments from above. If I turn off DHCP on the airport express then any friends who come over to use the wireless internet will need to be personally configured. Could I just assign the Airport Express a static IP address on the wired router, keep a DHCP on on the express for my friends and turn off DHCP on the wired router?
3. I have a PS3. I don't want to slow my gaming speed down. I intend on plugging the PS3 into my existing router (wired or wireless router, I will have it wired though) Will daisy chaining the express off of the router slow down my PS3 connection when other users are not using it?
I spilled alcohol on macbook keyboard, so I bought and just received a wireless keyboard which I paired with my computer, but the shortcuts at the top of my keyboard aren't doing what they should be doing. I went into system preferences and was able to change it so I can change the brightness, but from F7 to F12, where you are suppose to be able to change the song, play/pause, mute and turn the volume up and down, it does other things. I've tried adding an application to my keyboard shortcuts, added iTunes and then wrote "Volume Up" and set it to F12, and "Volume Down" and set it to F11, but it didn't work. Is there certain words I have to put for it to work?
I recently changed the batteries on my wireless Apple Keyboard. When I turned the Mac back on the keyboard wouldn't connect. Confused, I went in to system preferences where I got this message. I've searched for the problem in Apple Support on their website but to no avail. I have Applecare. Is this something I need to take up with them? Should I take my Mac to a genius bar?
I have an HP office jet J4680. I have used it wirelessly by being connected to my time capsule network and printing from my macbook for over a year now. I just moved and changed the name of my time capsule and the printer is no longer connected. I have looked around on how to select the new network but I don't see this option. How can I link the printer with the network again?
Info: MacBook, Mac OS X (10.7.3), 2 ghz intel core 2 duo, 2 gb, ddr3
What's the best way to wirelessly b/up 3 mbp's to one external HD? I have 1 using Lion, 2 using Snow Leopard. I just purchased a Seagate 3T b/up for this process. I also use an Airport Router so my thought was to plug the HD into the Airport and use TM.
My dock keeps returning to previous setting. It simply throws out added Applications and changing the order back to how they were before. I deleted the dock.list thing in preferences which made it worse. Now i only have the original Apps in my dock.
I've recently purchased my first Mac (the new 13.3 inch air model). I seem to be having a bit of a problem with wireless networking, though. It seems that my Mac will reconnect to my wireless network perfectly after resuming from sleep mode just fine for a few days, but after those few days, it will mysteriously stop being able to get an IP address from the DHCP server (my wireless router). My PC is able to connect to the network just fine and always seems to be able to get a new address, but the Mac just loses the ability. I have found that the only way I can get the Mac to start grabbing an IP address from the router is by going into the router settings and changing the RIP mode to a value other than what it currently shows. I generally try to stay in RIP_2B mode, but I change it to some other random value whenever it stops connecting.
So i want to change my folder icons back to their original state, I found a set online with the default leopard icons in PNG format and I tried copying and pasting in the get info screen like you normally would but all i get is that white little preview sheet as the image (see attached screenshot)
I then found out all the original icons are saves in the resources folder so i tried those both in ICNS format and converted one to PNG but still no dice.
Anyone else have this issue....my Mom has the new 21.5" iMac (base model) with the wireless keyboard. The Magic Mouse battery level changes, however the keyboard battery level stays at 100% all the time?
I am trying to change back to the Apple Mail.app 3.5 from Microsoft Entourage and I can't seem to achieve this. I am afraid my Entourage will crash soon because my Database is currently 10.2 GB large. I had to switch 2 years ago from Mail to Entourage, after I lost all my mails because the Mail.app was corrupted. I have had a change of computer although I did migrate my data and was hoping that the mail.app was working better but it is doing strange things like importing folders with no content - although it marks them with the amount of mails located within. It also refuses to import (admittedly) large amounts of mails from Entourage, it doesn't matter if it is just a single folder or several folders. It hoards some old mails in its INBOX which remain there even after I have erased them numerous times. They just keep coming back.
When I use the import option of the mail.app it will not take over all my mails but will save parts of the database or crash when I try to feed it mBox files. I realise my databases are very large but there must be some way to import data from one programme to another. I think somehow my mail.app is broken or it can't handle the huge Entourage database, is there some way I can discover whether this might be the case? I am starting to think I should stick to Entourage because it has been performing faithfully for the past years and I like the appearance more, but because I had database issues under Entourage 2004, I'm afraid my huge database will someday become irreparable. I have a 2.4 Ghz Macbook Pro, 2GB Dram, System 10.5.6, Entourage 2008 and of course the mail.app which I've had to reinstall (with Pacifist) and fix with the new Apple Mail Update that was issued on DEC 23, 2008 (which is supposed to solve stability issues).
I'd just like to change the Snow Leopard mp3 icon (ugly and dark) back to the nicer, lighter, friendlier icon that was used before my upgrade. It must still be on the system because often when I load a new window with mp3's, the old icon is visible for a second and then changes to the ugly Snow Leopard icon. By the way: if you select an mp3 file in Snow Leopard and select the Info for it, you'll see the previous icon up at the top left of the Info window that opens.
When we share internet connection through ad-hoc wireless network, each individual connecting to our network will be assigned with an unique IP Address and other required fields will be filled with proper data(Gateway and ..).
I used this feature to access my iPad through wifi, and had no intention of sharing an internet connection. Now that I don't have an internet connection to share, my computer doesn't give any IP to my device, therefore my computer is unable to see my iPad on the network.
I also tried "Create network" feature of mac, but again, since IP addresses have been assigned by self, I'm not able to see my iPad on the network.
I just set up bootcamp on my iMac and windows is working great. The only problem is I cannot get back into OSX. I left my apple keyboard at home, and am now using a wireless logitech keyboard and mouse. When I boot up my computer, I hold down the windows key 'option' when the grey screen comes up, but the options of what to boot never comes up. What am I doing wrong? And if its because I need the apple keyboard, is there any workaround? I'll be stick in windows for weeks if thats the issue.
Having trouble on my mac while trying to connect to the internet using the built in Ethernet.
It says under network: Built in Ethernet is currently active. Built in ethernet has a self assigned IP address and may not be able to connect to the internet.
I hit the IPv6 and/or DHCP and it locates a IP just not a router number. Is this what is stopping it from connecting? Please help as I have an AP test I would like to study for....
When I make connection with my router I do not have internet, but I go to my network options and I click TCP/IP and then "renew DHCP-lease". The "Router" number change from 192.168.2.1 to 192.168.3.1, and then my internet works. But if I have to restart my mac for some reason, it jumps right back to 192.168.2.1, and i have to click "renew DHCP-lease" again. I have this on my both Macs (MacBook unibody allu, and MacBook white and also on my iPhone).
I have a Mac OSX Server (10.4) connected to a switch with various Airport Express terminals around the place. Macs can connect to the network wirelessly (with 128 bit WEP) and WIRED totally fine... but when I try and connect a windows PC either using wireless or WIRED... an IP address isn't assigned. Windows just says "Limited or no connectivity"...
The service shows running but will not give an IP address to Mac or PC. As the leases are running out on the machines they are not being renewed. I restarted the service and then the server. Then I reset the DHCP Client list.I turned on a computer lab so that they would all grab a new address.... none of them did. I logged on to a computer and told it to renew its DHCP address and nadda. If i assign a static ip they are fine
I have recently purchased a USB Ethernet adapter so I can setup NAT on lion server that runs on a MacBook. I was shocked when it blew away my DHCP Config after I set up NAT, but I stuck with the scope it chose and added the correct DNS and gateway settings.Whenever I start DHCP now, the logs tell me the Config cannot be found, and it blows away all of my modifications to DHCP. On top of that, it won't hand out any addresses.If I stop DHCP, the system logs start telling me that "natpmpd" has started, and then it begins to hand out addresses. The problem with this is, I can't make any changes to the DHCP settings it uses, which means my clients are now getting the incorrect settings for the gateway and DNS.Also, when I modify the Scope with DHCP stopped, the logs tell me it cant update the subnet because it was not found.
I have setup OS X Lion server to act as the DHCP and DNS server for my local network. DHCP provides gateway address and the local DNS server address.  DNS is set to forward to my ISP DNS servers. 'A' records and 'PTR' records have been created for the various servers on the network and I am able to resolve the servers via dig by name and address. I can also access the internet without issue. DHCP is handing out IP addresses to Windows clients on the network but I am unable to locate the machines with DHCP addresses in DNS either by IP address or FQDN. The windows clients are able to access the internet without issue. Looking at the DNS log there does not appear to be anything recorded when the DHCP address is allocated. Is there something special that needs to be setup either in DHCP or DNS that will allow DHCP to record the host and address details in DNS?
I own a MacMini Server in my home network with Lion Server installed. I configured the DNS Service with a primary zone, providing nameserver (MacMini) etc. Server Admin tool create also a reverse zone 0.0.0.10-in.addr.arpa (my IP Range is 10.0.0.I own also an Airport Extreme Base Station (4th Gen) acting as DSL Modem, DHCP and NAT and creating 2 Wireless networks (private and public network) and it's correctly set up for internet access... In AEBS settings the DNS Servers are 10.0.0.3 (MacMini) and 8.8.8.8...With these settings everyting works fine but all the devices (other Macs, windows PCs, etc.) cannot ping each other... The only machine they can ping is obviusly the MacMini because in the DNS settings i punt manually a machine (A) record...
My question is: is possible to setup Lion Server to dinamically update DNS records using AEBS DHCP entries and reservations ? If possibile i don't want to add all the record manually and I don't want use the AEBS only as an access point...

We have some Education iMacs that I am having some problems with. XP can be fully up to date (except SP3) without any problems, they are connected to the domain, get an IP address, correctly sync time and process group policy settings at a computer level prior to the logon screen. All this is using the ethernet port (not wireless). As soon as SP3 is applied, they don't get a DHCP address until after login, therefore they don't sync time, process policies etc. If I uninstall SP3, back to working. I have reproduced this several times on different Macs (we have about 90 that are exhibiting this). Tried different version of bootcamp drivers.
If I reserve the address in DHCP, it doesn't make a difference. I seem to only have 2 options: 1. Manually enter an IP address in Windows (this is too time consuming) 2. Leave SP3 off (this means WSUS 3.0 SP2 won't work) Is there a newer ethernet driver outside the bootcamp package?
I am trying to get an older Macbook Pro running 10.5.1 online and it is not working. I'm currently using 3 other Macs on the WiFi network all running Snow Leopard, so I know that network works. I tried renewing the dhcp lease and I have it set to using dhcp and to configure ipv6 automatically, and there are 2 ip addresses under dns servers (I typed these in because they showed on my other MBP). I can't even upgrade the MBP because I have no ethernet cable and can't plug it in to update it. I can do to get it to work?Â
If I select from the menu bar another available wireless network (one without a password for example) and then switch back to my own wi-fi network, am I still safe?
Did the fact that I connected to another network present any risks?
I did not send any private info during that time, any risks of getting hacked?
I have a G5 Duel 2GHz Power PC, Recently I was losing the time, date and wireless settings so I assumed as my machine is now 4 years old the PRAM battery was up for renewal.This has now been replaced but I'm still losing my settings, not all the time but randomly, sometimes I lose my wireless key sometimes I lose time and date sometimes both, this can happen daily.
I have removed the (New) Battery and checked the voltage and it reads 3.6 Volts, I haven't checked this under load though, so presuming that the battery is OK, what else could cause this.. a failing System Board?
I had Time Machine making wireless backups from my MacBook to a LaCie hard drive plugged into an Airport Extreme Base Station. It's worked great for at least year. The 10.5.8 upgrade seems to have broken it. It's still not an Apple supported configuration.
Just purchased a new iMac that came with a wireless keyboard. When I am working on accounting documents, I wish to use a numeric keyboard. The apple numeric keyboard I purchased does not seem to always work when I turn on my computer. It seems to only want to pick up the bluetooth keyboard. I have tried disconnecting the bluetooth keyboard but then it says "no keyboard found" even though I have the numeric keyboard plugged into the USB.
