Static IP + DHCP in Preferred Networks - Kind of Stumped

Hi,
Here's my situation:
I log onto 4 different networks throughout the day. Two of them have IP addresses that are managed by DHCP (school +lab), the other two are static IP.
Right now, I have to go to Preference Pane\Network and change the TCP/IP setting from static to DHCP depending on if I'm at school or not.
Is there a way in set the DHCP networks to automatically obtain an IP using DHCP, and the static IP networks to connect to the address I decide?
It would really make my life a lot easier.
Thanks

Yes, very easy. Make a New Location for each, each with it's own parameters, and even Interface if you care to.
Switching is a simple trip to the Apple Menu>Locations.

Preferred Networks by Location in Mavericks

Back in Snow Leopard, preferred WiFi networks were stored separately, in different lists according to the location chosen.
That worked great because I have 2 routers at home, one for my ISP and one for my VPN.
When connected trough the ISP router, the DNS Servers are chosen automatically.
If I want to connect trough the VPN router, I must specify the DNS Servers, for example OpenDNS.
So I had 2 locations, one for each router.
When I chose either one of the locations, it automatically connected me to its respective router.
It also worked for assigning Static IP addresses for the computer, a different one for each router.
The problem with Mavericks is that all Preferred Networks are listed together, and not grouped by Location as it was in OSX 10.6
Now It's a mess. I have to manually choose my desired network.
The problem is that if the other network comes out first in the list, the computer will connect to it.
If it doesn't match my chosen location, I will then have incompatible IP and DNS settings for that router.oes
Does someone else have this problem?
Is there a way to revert to the way Snow Leopard handled Preferred Networks?
Thanx!

I wish I would have taken a screenshot. The "kind" option is back after a reboot. Grrr.

802.11: "Preferred networks" vs. "A specific network"

I've got a new MacBook Pro and it appears that -- at least in my opinion -- has eliminiated one of the key advantages OS X networking has over Win XP.
With my G4 PowerBook, I can create a one-to-one relationship between locations and network access points. For me this is critical, as my work location has multiple access points -- some on our corporate network and some open to the internet. For the corporate nets, I have a static IP address and need various proxy configurations to be stored, whereas for the public nets, its DHCP and no proxy info needs to be stored.
On the MacBook Pro, it appears to me that I can't force network settings to access one and only one access point per location setting. Worse, I can't even change the prioirties of access per location.
This causes unpredictable behavior when my truly preferred access point is momentarily out of range. It appears that the MBP is grabbing another access point automatically. When this happens, my network settings are incorrect, and my connection is broken.
Am I missing something obvious? 'Cause this is the exact problem I've had with XP for years -- and something that has always been a ton better on Mac.
17 in MacBook Pro Mac OS X (10.4.6)
various Mac OS X (10.4.6)

Thanks for the suggestion, but the behavior described in the article is the actually the issue. Here's the problem: in my work environment, there are three VLANs with three APs, all three are always visible from my desk. According to what I'm doing, I need to shift between them a couple time per day.
Physical Location: Work
Access Points Available:
- "Internet" (closed SSID, DHCP, no proxies)
- "Corporate" (closed SSID, DHCP, proxies)
- "Development" (closed SSID, static IP, no proxies)
Location "Outside Network"
- Preferred Airport: "Intenet"
- DHCP
- no proxies
Location "Inside Network"
- Preferred Airport: "Corporate"
- DHCP
- appropriate proxy settings
Location "Development Network"
- Preferred Airport: "Development"
- static IP
- no proxies
So the "Preferred network" option would work (though less than optimum) if I could change the order based on location. It would be optimum (and better than the 10.6.4 PowerPC version) if I could change the order and add/delete netwoks according to location. Unfortunately, there seems to be only one preferred network list that is global for all locations. And that causes the unpredictability that I tried to describe.

How to set up both static and DHCP assigned addresses on an AirPort Extreme

I recently bought an AirPort Extreme to replace my failed Cisco/Linksys router.
I am having trouble figuring out how I can configure the Extreme to support the already static IP addresses on my network as well as assign IP addresses via DHCP to a few devices where static IPs are not supported, i.e., work laptop.
Additionally, when DHCP is turned on, are my only options the 10.0, 172.16, and 192.168? What if I am running something like 10.10 or 172.30?
I am far from green when setting up computer networks, but this AirPort Extreme is making me pull my hair out.
BTW, I have access to a number of computers running a number of OSes including Windows XP, 7, and 8, as well as Mac OS X Snow Leopard and Mountain Lion.
The Mountain Lion or Windows 7 machine would be the preferred ones to configure the Extreme. I already have the AirPort Utility software running on them.
Any help would be appreciated.

I have found the 'DHCP Reservations' option on the AirPort Extreme to be buggy. I seem to remember it causing IP conflicts for some reason. I think what I remember is that if the computer with the reservation was off, and the DHCP server then handed out that IP to another DHCP client, then there would be a conflict when the reserved IP computer was turned back on. Maybe it was an issue in ealier versions of the AE or OS X as the case may be, and maybe it's been corrected, but I've never bothered using it agian since the method I describe below has always worked without fail. Also, I'm guessing DHCP Reservations would work fine if one manually enters IPs outside of the DHCP range but in the AE 'DHCP Reservation Setup Assistant' the IP options provided are within the DHCP range which to me makes no sense and increases the potential for IP conflicts.
Here's what I do to setup a mixed environment of static and dynamic IPs on my network. It works like a charm and does not require the DHCP server (beyond the distribution of dynamic IPs to hosts using DHCP).
For machines on my network that are accepting services from the public network, I set them up with static IPs using the 'Manually' option (System Preferences/Network/Ethernet/Configure IPv4). The settings for 'Router' IP address and 'DNS Server' IP address should both be set with your gateway/router LAN IP). Use an IP address below or above the DHCP range of adresses (in AE/Internet/DHCP/DHCP Beginning & Ending Address).
i.e. if my subnet is 10.0.1.1 and my DHCP range is 10.0.1.100 to 10.0.1.150, you could set the static IPs on your local hosts as 10.0.1.x where x = any number from 2 - 99 or from 151 - 200 as an example.
All other machines and devices that do not require static routing are setup as DHCP clients and get a dynamic IP from the AE. To me it's a simpler setup though it might take a little extra time to setup initially.

WiFi Sense Not Very Sensible - Preferring Public Hotspots over Preferred Networks

When I am out and about WiFi Sense is really good as it automatically connects to public hotspots and I only need to open a browser and press ok, etc.
However when at home I have BT and have set up my own WPA network connection but the router also has BT WiFi on it and even though I am connected to my home WPA connection and it is a "preferred network" and set to be connected to automatically
why does the phone keep disconnecting at regular intevals reverting back to the BT WiFi connection?
When the phone switches to BT WiFi the internet is blocked until you sign into a web portal so as a result the phone uses up all my data connection as it reverts to 3G/4G and also the push email stops working.
So is there no way that WiFi Sense could be more "sensible" and connect to my preferred network in preference to the public hotspot then only connect to the public hotspot if no preferred networks are available?
I have friends who have Windows Phones and BT internet and have the same issue as well.
Thanks

You are welcome. I'm glad you got it back up.
(1) You say you did the symbolic link. I will assume this is set correctly; it's very important that it is.
(2) I don't know what you mean by "Been feeding the [email protected] for several weeks now, 700 emails each day at least." After the initial training period, SpamAssassin doesn't learn from mail it has already processed correctly. At this point, you only need to teach SpamAssassin when it is wrong. [email protected] should only be getting spam that is being passed as clean. Likewise, [email protected] should only be getting legitimate mail that is being flagged as junk. You are redirecting mail to both [email protected] and [email protected] ... right? SpamAssassin needs both.
(3) Next, as I said before, you need to implement those "Frontline spam defense for Mac OS X Server." Once you have that done and issue "postfix reload" you can look at your SMTP log in Server Admin and watch as Postfix blocks one piece of junk mail after another. It's kind of cool.
(4) Add some SARE rules:
Visit http://www.rulesemporium.com/rules.htm and download the following rules:
70sareadult.cf
70saregenlsubj0.cf
70sareheader0.cf
70sarehtml0.cf
70sareobfu0.cf
70sareoem.cf
70sarespoof.cf
70sarestocks.cf
70sareunsub.cf
72sare_redirectpost
Visit http://www.rulesemporium.com/other-rules.htm and download the following rules:
backhair.cf
bogus-virus-warnings.cf
chickenpox.cf
weeds.cf
Copy these rules to /etc/mail/spamassassin/
Then stop and restart mail services.
There are other things you can do, and you'll find differing opinions about such things. In general, I think implementing the "Frontline spam defense for Mac OS X Server" and adding the SARE rules will help a lot. Good luck!

"None of your preferred networks are available" but I can see them!

Occasionally when I start up my MacBook I get a window saying "None of your preferred networks are available," even though my network is listed among those located. If I try to connect via network preferences it tries, but then tells me the connection timed out. I am connecting via wifi. The only thing that works is to turn the router off and restart it. As soon as it has started up again and has a network connection, I can go to the AirPort icon and connect to the network.
I have tried re-entering the network password, restarting the computer, turning AirPort off and on, removing and changing firewalls, but nothing has helped.
Any ideas?

Welcome to Apple's discussion groups.
It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease".
6) In the folder /Library/Preferences ( not <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

MacBook Pro 15" can't find wireless preferred network after wake-up

Hello all
I've this problem with a MBP 15" (SnowLeopard 10.6.6): it doesn't find my preferred wi-fi network after waking-up from sleep.
Settings:
- on the MBP there's a preferred Location for this wi-fi connection
- wi-fi, DHCP and DNS managed by an AVM FritzBox 7050 (not visible SSID, MAC restriction, WPA2 pw)
- the channel I've set is different from other wi-fi around the building
The same network works perfectly using an old iBook G4 and an iMac, and other Windows PCs too.
Sometimes the MBP AirPort card just can't find the preferred Fritz network, while it does sees other wi-fi in the same building. Even using NetStumbler doesn't help.
I need to try to add manually "another" network several times before the MBP joins the Fritz wi-fi.
I already deleted and recreated the preferred network.
Is this a known software issue, or it can be a faulty AirPort card ?
thanx
Gabriel

Hello all,
after a lot of testing, using both the MacBook Pro and an old iBook G4 (the latter was working perfectly), and having on both machines some wi-fi sw such as KisMAC and iStumbler (while watching the wi-fi monitor on the access point consolle), I found that:
- the MacBook Pro is much more sensible to noise;
- it is better to use a channel with little noise, even if the are other devices on overlapping channels.
Eg: I found the channel #13 was free and there was only 1 other PC on #12, but there was a lot of noise. After trying all the channels, I decided to use #4 because there was little noise, even if there were many PCs around on #5/6.
So, don't care (as one should usually do) too much about not overlapping channels; instead, search for channels with little interferences.
I hope my solution can help you

Apple TV preferred network

I have an ATV which was formerly connected wirelessly to a Netgear wireless router. I now have a Time Capsule which I would like the ATV to connect automatically to, rather than defaulting to the old wireless. I am able to connect to the TC network manually, but it defaults to the Netgear every time I switch it on. Is there a way of telling the ATV to forget the Netgear, or to change the preferred network?
Thanks.

You have two possibilities. You could disable the wifi on your DHCP server (your modem) and just have one wifi network, which would likely solve your problem anyway. Or you can keep two wifi networks if there is a reason. I have 5 wifi channels in use but all on the same network because the wifi base units are quite far apart and wouldn't cover my home with less and I also have quite a lot of traffic which I can spread between them.
This is "My tv set up"
Which ever way you set it up you must have the extreme set up in bridge mode, if it issues DHCP addresses it will make two devices doing so and everything will get confused, not on that but if the computer is on one network and the tv is on another they simply won't work.
One network doesn't mean only one wifi, one network means one device issuing the network addresses.

Macbook Pro no longer auto-connects to preferred network

The title says it.
While my computer connects automatically to some (maybe all but one) of my preferred networks, it now does not connect, annoyingly, to the one I use the most often (let's call it NET).
I've triple checked that it's preferred and should connect automatically, and the computer remembers the password, so that if I manually select NET, it connects no problem. But:
a) It won't auto-connect to NET, and
b) If I turn my computer on, when it presents the list of networks to me, I have to wait for it to reload the list, cause if I click on NET originally, it doesn't connect, and I have to refresh the list and try again.
c) Figured that might mean that it's just taking longer to load the networks and is showing me a list before it's actually picked up on the networks, but waiting forever doesn't make it autoconnect; it just refreshes the list.
Any ideas? This is a huge pain.

No idea. You could try deleting the file
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
... and restart your Mac.
To find that file quickly, select the above path (triple-click the line), control-click to bring up the contextual menu, and select Services > Reveal. Drag that file to the Desktop, or directly to the Trash.
This will completely erase your AirPort network preferences, requiring that you select your Wi-Fi network and authenticate again.
What OS X version are you using, and are you using an Apple AirPort Base Station, or a third party product?

OS 10.8.5 Wi-Fi doesn't find "Preferred Network"

We installed a new modem provided by Comcast that has built in wireless. After naming and establishing the password for the network, I successfully connected via my MacBook Pro, which detected it. Once connected I accessed the "Advanced Settings" screen in the Network control panel.
Under the first "Wi-Fi" tab I dragged the new network to the top of the list of "Preferred Networks." I also confirmed that the "Remember networks this computer has joined" check-box was selected.
Yet each time the computer wakes from sleep or is restarted the Wi-Fi utility scans for networks and doesn't connect to any. When I click on the control bar icon for Wi-Fi the network appears -- usually at the bottom of the list -- and when I click on it the computer connects immediately.
Obviously this defeats the point of remembering preferred networks and is a nagging time-suck at the start of each work session. Has anyone else experienced this problem and discovered a solution?
Thanks!!

System Preferences > Network > WiFi
To give a network the highest priority, drag the name of the network to the top of the list. This is the network your computer will attempt to join first.

Why won't my Mac automatically connect to my preferred network?

My router at home is one of my preferred networks but it won't connect automatically. I always have to go up to the wifi menu and connect to Home manually. Why won't it connect automatically?

Try to drag the network to the top in the order of networks.
System Preferences > Network > Advanced > Wi-Fi
To delete the network, select it and click "-" minus button underneath.

Dhcp across two network

Hi,
We are running into a problem with dhcp. Diagram is attached here.
portion on the left side belongs to Network A & right side is network B. These two networks are seperated by Firewall B.
Firewall B has minimal rules & permits traffic between the two Network A & B. On network B , 6506 does all routing.
The edge switch in Network B has users connected to it. But these users(vlan50) connected to this edge switch are actually belonging to Network A, they are physically attached there.
Layer 3 interface Vlan 50 - 172.16.50.0/24 is configured on the Firewall A & on its interface , dhcp relay is pointed to 172.16.70.10 ( dhcp server).
Firewall A does all routing for this portion in Network A.
Appropriate routing is in place on both sides. We have created vlan 50 ( layer 2 ) in Core 6506 in Network B.
We are trying to see if these users (in vlan 50-172.16.50.0/24) can get an ip address via dhcp server from Network A.
This proves to be unsuccessful.
It will be really helpful if people can help us out.
Thanks in advance.

John, thanks for the reply.
Layer 3 for Vlan 50 - 172.16.50.0 /24 is configured on Firewall A . The 6506 only has vlan 50 in its layer 2 database.
Helper address/relay pointing to 172.16.70.10 is configured on Vlan 50 interface on Firewall A.
Both the firewalls have the broad rules which permit all traffic in between these two segment of network.
Appreciate all inputs.

What "preferred network" do I use

In call settings there is a preferred network setting... Mine came default on "global" mode can I or should I change it to "CDMA" mode? Anyone know of a reason why I shouldn't? I live in Indiana and will not be doing any international traveling.

setting it to "CDMA only" should slightly improve your battery life, due to the GSM radio being turned off. If you're not traveling to other countries, definitely switch it to CDMA only.

Wireless Connection - Can't choose 'By default, Join: Preferred Network'

Have just bought my partner a second hand PB G4
Am trying to get it to connect to internet and printer via airport to my existing (and working) network (G5, Airport extreme base station and ADSL modem)
On the network prefs pane of the PB the ability to select 'join Preferred network' is grey (says automatic) so I can't select the network I want
Same in Internet Connect
Airport is turned on but says 'no network selected'
Network status pane says internet sharing is on (it isn't) and is using airport to share the connection. Status light is amber
Probably fairly basic but very frustrating. Any advice appreciated
Powerbook G4 Mac OS X (10.4.9)

Network status pane says internet sharing is on (it
isn't) and is using airport to share the connection.
Status light is amber
I think you may be a little confused here. Internet Sharing is for one computer to connect thru another. Let's say your G5 had two ethernet ports, one of which was directly hooked up to a DSL modem, over which it did PPPoE to your ISP. You could then use Internet Sharing to connect a second computer to the G5 via ethernet and use the G5's Internet connection.
I don't think this is your setup (although I've been very wrong in the past!). It sounds to me like everything is going wireless and the base station is the one with the Internet connection. So you don't need Internet Sharing at all.
What you need to do is to start at the beginning. Looking at Internet Connect, in the Airport tab, do you have a selection of networks? If you select your ABS, does it show good signal strength?
