MBP C2D - no wireless networks show up: possible soultion

If you can't see any wireless networks, one possible solution is to change the channel of the network.
I've got a quite old Netgear MR314 wireless (802.11b) router. Yesterday I got my Macbook Pro C2D and tried to get connected to my wireless home network. Airport was turned on, but no wireless networks showed up in the list. My Ibook could access my network just fine. I tried to disable all wireless security such as WEP and access control based on the MAC address of the Airport card, but it didn't help. Sometimes I even saw some neighbor's network, but not my own.
Today I logged in to the setup page of the Netgear router and played around with channel setting. By default it was set to 1. Channel 2 didn't work, but when I tried channel 6 or 11 (didn't try all of them), my network showed up in the list and I now get full reception!
Hope this helps someone.
MBP C2D 2,33 / 2 GB Mac OS X (10.4.8)

I had the same problem, turned out my airport card inside the macbook was fried. Apple replaced it and while they were doing it they fried my MB and RAM. So after 2 days I have pretty much a new computer. Buy the extended warranty.

Weird wireless networking showing up in my range

I have two off wireless networks showing up in my range. They are: 1. Jet blue hot spot 2. Triple a network Does anyone have any idea what these are? They definitely look suspicious.

It could be your neighbor's wifi. Use a more unique SSID for your wifi. And make sure that when you configure your router, connect it manually (wired) to your PC - do all the necessary settings then save.
You'll never know, you could be changing someone else's wifi settings when you're doing it wirelessly.
A unique SSID is a good way to start. Then change the default password of your router.

HP7520 Connected to Wireless Network, shows up on Wireless Laptop, Unable to Connect

After working fine for several months (aside from turning itself off and needing to be unplugged and re-plugged all the time) my HP7520 will no longer print from any of the Laptops in our home.
The printer says it's connected to the network, shows up as Online and Ready in the Printer Dialog box, but every time I try to Unable to Communicate with Printer message.
This happens on laptops running both Windows 7 and Windows 8. I have a cisco wireless router.
Any help appreciated!

Welcome to the forums NYCNancy,
I saw your post about your Photosmart 7520 no longer communicating with any of your laptops. I would like for you to try assigning the printer a static IP to see if that will help the communication issue.
Click on this link and scroll down to " Step seven: Assign the printer a static IP address " and follow the instructions.
Let me know the results!

Defunct wireless network shows up in network window

I bought a new wireless router (a time capsule) and set up a new wireless network. When I click Go - Network, both my old and new networks show up, even though the old one is now defunct. I've already gone to Preferences - Network - Airport - Preferred Networks and deleted the listing for my old wireless network. It no longer shows up in that list, but it still shows up in my available networks. Any ideas on how to delete the listing of the defunct network?

Hi beejay,
Have you tried turning off Airport, rebooting your Mac, turn Airport back on, then check available networks???

I boughtThe new iPad three week ago and I want to change it for a 32 gb and wireless / network is this possible

I bought an iPad three weeks ago and I will like to know if I can exchange it for the 32gb and the wireless and network

KP is right, Apple has a 30-day return for refund policy, but since you are beyond that time your best option may be to sell on eBay or Craigslist, or such, and put the money towards the one you want. Apple is very generous about returns during the first two weeks but they then cut it off.

MacBook Pro will not connect to Cisco Wireless Network

I have just bought a brand new MacBook Pro, running Leopard (OSX 10.5.1) and I just cannot get it to connect to the Wireless Network at my workplace.
The MBP connects to wireless network and authenticates just fine, but will not obtain an IP address from the DHCP server.
The wireless network consists of 16 Cisco Aironet 1200 Access Points controlled by a Cisco Wireless Network Controller. It does not broadcast its SSID and is WEP 128-bit hex protected.
Changing the network from WEP to WPA is out of the question for me as this is under the control of my customers IT Department and they do not have any problems with their PCs connecting to the network. It appears to be an Apple issue.
For reference, my old Vaio PC, my Nokia N95 and my iPod Touch ALL connect to the same wireless network without any problems whatsoever, first time, every time!
If I boot into Windows XP from my Boot Camp partition, XP can connect wirelessly to the network without any problems, so it is not MacBook hardware related...
It has to be a bug in Mac OSX... doesn't it?!?
Things I have already tried (following suggestions on many forums):
* Switching Airport off/on
* Deleting various network-related Plist files and rebooting
* Manually assigning an IP Address (not really permitted but doesn't work anyway!)
* Disabling all network adaptors except Airport
AP Grapher shows that the MBP is connected to the wireless network, at good strength, and packets are being sent and received, but Internet Access is not possible as no IP Address has been assigned. Instead, my MBP shows a 169.* IP Address (self-assigned). It should be a 10.1.255.* address.
Can anybody please help? Thank you.

i posted this same reply elsewhere because it worked for me for my Buffalo wireless router: try manually setting your IP address instead of relying on DHCP, which sometimes (I don't know why) doesn't work well with Macs. It's a good get around. I am a happy Mac user but nothing is perfect on earth, and when the Mac gives problems, it does give a lot of frustration. Macs are not as easy to troubleshoot as Win because a Mac is built to be user friendly(and it works most of the time), meaning a lot of the background computing stuff is hidden away from users to avoid user accidentally upsetting some settings.
Unfortunately, the highly automated troubleshooting wizards provided by OS X are not perfect so when these software wizards fail to resolve the problem, like my Network Diagnostics, I have to spend more time tinkering around. There's "Terminal" of course but then most of us, especially PC converts to Macs, don't know how to use it.
You should also try updating your MBP, see if there are any new updates being released.

Blocking a particular wireless network?

I'd like to prevent Airport from seeing or connecting to a particular wireless network - is that possible? If so, how?
I have a MacBook Pro, Mac OS X, version 10.4.11.
Thanks!
MacBook Pro Mac OS X (10.4.11)

Hi ghuggins, and a warm welcome to the forums!
I don't think you can block it showing up, but you can stop it connecting to it.
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select that access point.
Remove that access point with the minus button.
Launch your keychain access in Utilities and delete that access point keychain entry if it exists.
Go to System Preferences: Security. Check the box next to "Require password to unlock each secure system preference." Then lock Security.
Go back to the “By default, join:” page and click the plus this time to add your access point, if not there. Enter the correct password, save, reboot.

Home wireless network trouble

I got a new wireless router, Netgear WPN824 from Newegg, a refurbished product. I set up a home wireless network using the online manual on the Netgear website. The router works well for the wired setup. But I could not connect to wireless.
My wireless network shows up on the list of available wireless networks. I can connect to other wireless networks such as that of my neighbour's. I tried connecting to my network using both unsecured and secure WEP / WPA modes. Except once, I could never connect. That one time, as soon as I could connect and verify that I was indeed connected I thought the problem was resolved and so shutdown my system to see if i could connect again - alas, same trouble again. I use NetworkManager to connect, and here's the output for two networks - jaydoc which is my home network, and linksys, that of my neighbour's to which i can always connect.

Is the wireless router i got a dud, being refurbished i took my chances and maybe i wasn't so lucky..! Or is it something wrong in my network settings..? I tried shutting down everything and then turning the modem, then the router and finally the PC without the ethernet cable connected. Still I am unable to connect.
Any help is deeply appreciated. I am a total newbie in networking...!

So if its still a DHCP problem, it seems to be affecting only the wireless part. How can I make wireless use the same DHCP servers as the wired..? Or is there something else wrong here..?

Unable to connect laptop to wireless network

My MacBook Pro will not connect to my wireless network, but my iPad does so I know it must be a problem with my computer rather than the network. Any suggestions?
I'm not sure if there is some obscure setting that I need to change.

Give us more information, please.
Is your wireless network supplied by your ISP, your landlord, your own router, or something else?
What can you tell us about the settings on your wireless network? (Not the passwords.)
Did this ever work, or is this the first time you have tried to connect the MBP to this wireless network?
What model/year MBP is this? It has to be somewhat old if it is running Snow Leopard (10.6.8) as per your profile.

What type of wireless router w/new MBP C2D??

I have a new 17" C2D MBP on order and I would like to sort out my wireless home network before it arrives...
As I am new to the wireless world, I do not understand what wireless router would work for this new MBP. I have read about it having 802.11g technology, but I have also seen something about N technology... my local computer shop says that they don't have N technology yet, but will soon.
What is this all about? Is 802.11g G technology? What do I get to have wireless internet access with my new MBP at home?

If you have the MBP C2D and you would like to get a wireless router. I suggest that you get a 802.11n router, as it works for both 802.11b, 802.11g as well as 802.11n. It is common knowledge by now that the wireless card that is used in the MBP with the C2D is an Atheros AR5008 802.11n. Though it is recognized as an 802.11g in the current OSX 10.4, this wireless card has the possibility of being used at its native state of 802.11n. What does this mean to you? Well, the 802.11n is ~ 650% faster than 802.11g and has about 5X the range of it as well. Though 10.4 does not recognize the card as such, windows vista will (that is if you plan on installing it onto the system) and OSX 10.5 might (I don't if Apple, will support draft N [802.11n] of the new wireless standard, even though they put a wireless card in the system that is a Draft N card). So get a wireless router that uses 802.11n. It'll save you money in the future.
Ok, now I'm done explaining why you should get the 802.11n router. Now, as for those who might say otherwise. If you think the 802.11n draft standard is going to change much from now, until the standard is finalized, then you may or may not be right. But from what my professor explained to me about how the technology works, it probably won't change that much. If I were to explain it to anyone on this board about how the standard works, it would be a hopeless matter unless you have taken classes in state variables or control systems. But I guess there are more than enough resources online to find out about how the Draft N standard works. And that is my 2 cents.

New 15" MBP will not connect to my wireless network

This is my first Mac, so I will try to give as much information as possible.
I have a brand new (got it yesterday) 15" MBP and it refuses to connect to my home wireless network. It is an older "g" network using a Linksys router and 128bit WEP encryption. For reference - I have an iPad and 2 iPhones in my household, and those have all connected to the same network without problem, as have the 2 windows laptops that my wife & I use for work so I don't think it's the network.
Anyway - I fired up the MBP and went through the set up assistant. When I try to join my wireless network, it detects the network fine. I select the network and try to connect. It goes throught the process and then I get a prompt that says "Network conditions have changed". I click OK and it prompts me to enter the password for the wireless network. (At this point I have the little exclamation point in the wifi symbol on the top of the screen telling me I have no internet access - which I believe is how it's supposed to look).
On the password screen, I select "WEP 40/128 Hex" as the password type - on the security information screen in the router set-up it says "WEP 26 hex 128 bit" as the type, so I believe that's the correct password type for the MBP. I enter the 26 digit key (the same one that I used to connect the iPad/iPhones) and after trying to connect for a couple minutes I get the "Network conditions have changed" prompt again. I click OK, and then it tells me it failed to connect to the network.
I have tried entering the WEP key with a "$" in front of it and entering it with "0x" or "0X" in front of it and the same thing happens. I've also tried changing the password type to "WEP Password" and entering the password I used in the router to generate the hex key, and the same thing - it tries to connect and then I get the "Network conditions have changed" prompt and it tells me it failed to connect.
I am at a loss. I haven't touched the router's settings because everything else I have (Apple and non-Apple products) have all connected just fine - all I've had to do is enter the WEP key and they have connected.
What am I doing wrong? Is the MBP somehow different and I need to change something in the router settings? Any assistance would be greatly appreciated.

Yeah, BT Hubs do not play well with HP printers, probably because they do not strictly follow wifi standards.
One thing to try is to change your encryption to WPA ONLY.

Problem connecting MBP to established Linksys wireless network

just got MBP 2.16 (my first mac!). Having trouble connecting to my established linksys wireless network. I have the BEFW11S4 (V.2) etherfast wireless access point + cable router with 4 port switch. Currently have 128 encryption enabled. The linksys router is broadcasting its ID (I can see "linksys" on my mac) but it seems to not accept the password. I tried entering the 26 WEP key, the passphrase, the WEP key in quotes, the WEP after a $ sign... all to no avail. please APPLE community, help out a mac noobie before i have to turn back to Bill Gates....

To find the IP address or the status, go to system Preferences then network. It will show you the status of any internet connections. You should see one for Airport, it will either show a green light and say 'Airport is connected to the internet' (or something like that) or a red light and say 'Airport is is active but not connected' (something like that). If you double click on Airport or click 'Configure' you will see tabs, click on TCP/IP and it will show all of your details including your IP address.
As for the other, it always refers to wireless networks as 'Airport' and that response is the standard response from a Mac.
the password should be typed in the hex section, not sure about the $ sign. I've never had to do that before. But if you can't connect even with no encription then I would think it is another problem. I would turn off the encription until you can at least get connected and then you can worry about the security afterwards.

Problem connecting MBP to established Linksys wireless network (Part 2)

Thanks to all who followed part 1 thread. I have been trying to wirelessly connect my new MBP 2.16 to my established linksys BEFWS11S4 network. I gave up on 128 encryption for now, MBP couldn't take it.
by playing with the setting and manual config I can get the MBP to connect to the linksys network, (I even see the mac on my Win XP's DHCP master table). In the network utilities I get a green status light. when i run diagnostics i get a green airport, airport settings, network settings and ISP. STill red are "internet" and "server". no conncetion with safari...
I know the MBP works becuase i was able to connect to my neigbors wireless network and will work when I hard wire it through built-in ethernet.
Anyone know why the airport wouldn't work here? any thoughts appreciated I have spent way to many hours on this......

OK so your router is issuing IP addresses. However, I would say there is definately something wrong with your router's config. Maybe your DHCP server on your router is switched off? Anyway by adding your own IP address that is half the battle, as you need more than an IP address to connect to the internet, that's why you can see it in the list but cannot connect to the net. When a computer is set to DHCP it sends out a message to any DHCP servers requesting an IP address, if it gets no response in a set time, it issues itself an address, like yours is doing, the address will probably look like this: 169.254.14.192, it's called an APIPA address (Automatic Private IP Addressing)
You see a router uses a NAT (network address translation) so that from the internet all the machines connected to your router would show the same IP address which would be the one supplied by your ISP. For this to work, each machine on your network needs to have a default gateway, which is the IP address that your outbound traffic goes to. If your router is not issuing an IP address then it's probable that it's not issuing this data also, so you can add it yourself.
On your windows machine, go to a command prompt Start>Run type cmd and press enter, then type ipconfig /all press enter, it will show you the IP address of your PC, your subnet mask and your default gateway. I am going to assume that your IP address is in the 192 range as most Linksys are. So let's say your IP address of your router is 192.168.1.1 (on the new ones they tend to go with 192.168.1.15) so whichever yours is, that is your default gateway, as that's the address of your router. So your PC may have 192.168.1.100 as it's IP address.
On your Mac go to the System preferences>Network and the TCP/IP tab and select manual setup in Airport. Type in an IP address like 192.168.1.101 (or one up from your PCs IP address, then type in the subnet mask 255.255.255.0 if that is the same as your PC and then where it says Router (this is the default gateway address on a Mac), type in the default gateway here. Select apply and that should now connect to the internet.
I would only use this until you can resolve your Router's issue. Maybe you can call them back and tell them your router is not issing IP addresses. Or get a friend to try his laptop and see if he gets one. If not then you know it's your router. I would bet money that it's your router, that's why you can connect to your neighbours but not yours. Also remember if you keep the manual setup if you go travelling, remember to change it back to DHCP or you wont be able to pick up any hotspots. You can save a TCP/IP setup on a Mac so you could save the setup and name it and when you go travelling change to default, or auto.
Let me know how you get on.

Unknown computers showing up under "Shared" on secured wireless network.

After reading through the forums, it looks like I am not the only person who has encountered this, but I haven't found any real answers and my situation is a bit different.
Yesterday, unknown computers started showing up in the "Shared" sidebar in Finder. This happened both on my MacBook Pro and my iMac. I have a password protected wirelss network. I know these are other people's computers and not just printers or peripheral accessories on my wireless network because they have names like "John Doe's Mac Mini" and "Smith-pc."
I understand that this doesn't mean that someone is trying to hack into my computer, that they could just have sharing enabled on their computer and it is broadcasting its availability for a connection. However, I don't understand how these computers are broadcasting it. I live on a farm in an isolated area where it is not possible for someone else to be picking up the signal from my wireless router. I think I have established that these are Bonjour connections because I can make them disappear from the sidebar by unselecting "Bonjour Computers" in Finder Preferences. I have checked all of the MAC addresses that my wireless router (Apple AirPort) says are connected and I can account for all of them.
My ISP comes in through a wireless antenna system. Is it possible that they suddenly changed something yesterday that is letting Bonjour signals from other subscribers to be broadcast through their network? I have used this ISP for a couple of years now and this just suddenly started yesterday.
Should I be concerned? I have gone through and made sure that file sharing is not selected on our computers. I'm not sure what precautions I would need to make with our iPads, iPods, etc. Is the appearance of these computers simply an annoyance, or am I in any way at risk?
I would appreciate any insight anyone can give.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Satellite not showing wireless networks, adapter seems ok

my satellite is not showing wireless networks and i can't figure out what networks are available. the adapter seems to be working properly according to windows device manager. i had to uninstall configfree, although i'm not sure that caused any problem. i have had to run a bunch of anti-spyware programs, registry cleaners etc., system seems much better but a few glitches.

It's possible, but it might be a lot more work to do so. It all depends on how soon you need to get it fixed. I'm not a network specialist so I can't really offer much in the way of assistance other than what I already did. It's possible someone else might have other ideas, but since you didn't post this in the Networking and WiFi Forum where it belongs it's quite possible that those networking specialists will never even see your post to respond to it. I know that I rarely go into the Networking Forum as it isn't my strong suit.
If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.
