Can't connect MacBook to PowerMac over Airport network

PowerMac G4 DP 1 GHZ, Mac OSX 10.5.8
MacBook Core 2 Duo 2 GHz, Mac OSX 10.6.2
When I try to "Connect As", nothing happens. Oddly, I can share the screen of my PowerMac on my MacBook with no trouble. I have File Sharing active on both. This only happened when I updated to Snow Leopard on my MacBook. Unfortunately, my aging G4 PowerMac won't support Snow Leopard.

Interestingly (or maybe not so interestingly) I have no trouble using my PowerMac G4 to connect to the MacBook. It's just a one-way issue with Snow Leopard not making contact with old Leopard. To further check the connection between the two computers, I changed the name of my PowerMac in it's Sharing Preferences and the new name immediately appeared on the side panel of a Finder window on the MacBook.
I use the PowerMac as a central filing system so this connectivity has always been a huge convenience for me. Am I stuck hoping a future Snow Leopard update will solve this?

Can't connect to 802.11 N AirPort network with Macbook Core Duo

So with my Airport Extreme, I set the router to be on 802.11n ONLY 2.5Ghz and my Macbook can't connect to it for some reason. But when I switch the configuration on my Extreme to 802.11n (802.11 b/g compatible) 2.5 Ghz, I'm able to connect with my Macbook.
I thought maybe the 802.11n enabler that came with the Extreme didn't work the first time I installed it on my computer so I tried to install it again but to no avail. I came to the conclusion that there was something wrong with my 802.11n capabilities on my Macbook by the test above, but can anyone thing of any other way to identify the problem? Can anyone think of a way to fix this problem?

To verify that 'n' capabilities are enabled:
Open Network Utility (found in the Applications > Utilities folder)
Under the Info Tab, choose Network Interface (en1)
In the section "Model: Wireless Network Adapter," if it says (802.11a/b/g/n), the 802.11n capability is installed. If it says (802.11a/b/g), you do not have the 802.11n capability.
If your MacBook has the "Core Duo" processor it does NOT have 802.11n hardware. Only the "Core 2 Duo" MacBooks have the 802.11n hardware.

Can't connect to computers on the same network and same office

Hi everyone, I have this problem from some time now, I have on the same network some computers with ethernet, and some with Wi-Fi.
All are connected to the C-Net Wireless-G Router.
My iBook is on the Wi-Fi zone (All have 10.4.11) and I can see the computers on the Ethernet area, but I have an iMac 2.0 next to my iBook and I can't see it.
How is that possible? Am I making something wrong with the subnet mask or IP address?
All are configured to use 192.168.1.254 as the router and on the subnet 255.255.255.0. Manually.
The IP variates from device to device on the 192.168.1.X numbers, starting with 100 on the iMac, and ending with 113 on an old 8600.
Wy can't I see the iMac?, si so close that I can reach her with my hands, but can't connect to transfer files over the network.
If anyone could give me a hand here, I will apprettiate the advice.
Thaks to everyone, Pablo from Argentina.

How is the iMac 2.0 connected? cable or wireless?

You are on a different subnet. In x.x.x.0 the x's are different.
All the computers are in the same subnet, cable ones and wi fi ones.
All are configured to use 192.168.1.254 as the router and on the subnet 255.255.255.0. Manually.

Look at what ip addresses you have on each machine.
I have different IPs on each machine, do you need the numbers?
Wy can't I see the iMac?, si so close that I can reach her with my hands, but can't connect to transfer files over the network.
Macintosh-HD -> Applications -> Utilities -> Network Utility.app
Use the ping command to see what is going on. Ping 192.168.1.254, source & destination machine. 127.0.0.1 is an alias of the machine you are on.

check out port scan. This will tell you if sharing is on.

Can't connect macbook pro to internet with airport extreme

Can't connect macbook pro to internet with airport extreme

If you have ethernet still on your MBP plug it in by ethernet and tell me if that works.
Tell me how the Airport is setup.. what broadband modem and router you have.
What OS on the laptop? Yosemite I guess.. since it is the most troublesome.
Did it work before whatever change was made? Has it worked in the past? When did it stop and what did you do that coincided with it stopping?
Upgrade to Yosemite??

I have a MacBook Pro. My mac can detect wifi. But will not connect. I did get connected vis TCP/IP settings but I can't connect to any wifi anywhere. Network diagnostic has a green light for wi-fi and wi-fi settings. Red light for the rest.

I have a MacBook Pro. My mac can detect wifi. But will not connect anywhere. I did get connected via TCP/IP settings but I can't connect to any wifi anywhere. Network diagnostic has a green light for wi-fi and wi-fi settings. Red light for the rest. (Network settings, ISP, Internet and server.)

Hello NotAppleSavy,
Thanks for the question. After reviewing your post, it sounds like the computer wont connect to networks. I see you have used network diagnostic. I would recommend that you read this article, there are a lot of other things you can do in this article that may be able to help you resolve or isolate the issue.

HT4262 How can I connect 6 computers simultaneously to Airport extreme?

I have tried troubleshooting several ways and the some computers work and others don't. How can I connect 6 wireless computers to Airport Extreme?

Matt
Is it possible to speak on the phone? The situation is so convoluted it might be easier to help me get back on track in person. When I first had this issue I got on an apple site that had a chat room in which I typed in my problem. After several missives back and forth, the apple technician asked for my number and we spoke on the phone. The technician walked me through rebooting the actual airport plug (as opposed to the router box) and got me up and running. Do you know how I can relocate that chat site for technical support?
Thanks
David

Can't connect N73 to PC over bluetooth

I can't connect N73 to PC over bluetooth with new Nokia PC Suite v6.84.10.4, I get this message "Cannot use the connection type. Check that all the needed hardware,software and drivers are available". This happened after I instaled new version of PC Suite and the patch to v6.84 didn't help.

I think the problem is in bluesoleil software It looks like PC Suit does not work with latest IVT Bluesoleil version 3.2.2.8. I tried with and witout patch and I even installed older version of PC Suite that worked before with older version of bluesoleil....

Can i connect my hdvt to an airport express unit using an ethernet cable from the tv to the airport expree, thus joining my wireless network for movie downloads

i have a 40 pioneer kuro hdtv with ethernet jack.
i want to connect it to my local airport network. The tv has some kind of "network" capability.
Could i connect by using an airport express to the tv via an ethernet cable;
Sounds unlikely. (tv also has a usb port).
thanks for any advice.

Thanks for reply.
I mostly want to get some youtube videos and also to send some photos to this tv.
would the netgear WNCE2001 allow me then to connect the tv to the local wifi net?

Can I connect two apple tv on same network and same apple ID at a time ?

Can I connect two apple tv on same network and same apple ID at a time ?

Welcome to the  Discussion Forums.
Yes you can do all that without needing to keep plugging things in and out. You will still need to manually turn on the receiver and turn down the volume from the tv though.

I can't connect to other computers on my network with computer names. Any suggestions?

In what way are you trying to connect? File sharing? Printer sharing? Screen sharing? Something else?
How are your computers connected to this network? What happens when you try to connect to them?
Best of luck.

Can't connect computers to printer (b210) via network because there are "other networks"

I can't connect computers to printer (b210) via network because there are "other networks matching your network name". This makes no sense at all. I have several Apple devices (iPhone, iPad, iMac) all with the latest software. The printer works fine when using the USB connection to my iMac. Nothing I do seems to solve this problem (rebooting, re-configuring, etc.). Help.

Hi Cgold,
If there are other networks matching your network name, then the printer will have issues connecting when you run the wireless setup wizard.
However, there are other options:
If your router supports 'Wi-Fi Protected Setup' with either a button to push on the router, or a pin to enter, you can choose that connection option under the wireless menu on your printer.
or
Change the network name that your router is broadcasting within the web page of your router (NOTE-this would force you to re-join all wireless devices back to the new network name you have created).
If I have solved your issue, please feel free to provide kudos and make sure you mark this thread as solution provided!
Although I work for HP, my posts and replies are my own opinion and not those of HP.

Pc with windows xl/sp3 can't connect / acquire ip address from airport extreme; meanwhile, my macbook in connecting fine. We have a wpa2 personal password

My husband's Dell with Windows xl (sp3) can't get an ip address from our new airport extreme. Nor can my daughter's Windows 7 computer. There are no firewalls in place. Both computers worked with my old Airport, though it was sssslllllllowwww. My Macbook works fine and is super fast compared to the old airport. We are using a wpa2 personal password.
Anyone out there have a cure for this problem so we can hook up those sad pcs?
Thanks a lot.
Elizabeth

First, make sure that the new Airport is configured exactly the same as the old one. Hopefully you saved the configuration settings in a file and can look at them to be sure.
If the Windows PC's can't connect with the same password, it's possible that the PC's were using an older wifi protocol like 802.11a or b. The new Airport is backwards compatible but has to be setup that way check to see what versions of 802.11a the windows computers support and make sure that the wireless mode of the airport is setup to accomodate them.
Can the PC's get an IP address if they are connected to the AirPort using an ethernet cable? If they can, that would help naorrow things down to a wireless issue and not some other configuration problem.

Mac Book pro can't connect to Internet through Apple airport extreme base station

I had problems connecting to the internet in the past with my macbook pro. One day it suddenly started working again but then I bought a second apple TV I lost connectivity. I have tried changing the IP address manually and while it shows me connected to the wifi I am still with out internet. When I hooked up the new Apple TV that I bought it booted my computer from it's ip address. The apple TV though wouldn't work and now nor would my computer. I ended up setting the Apple TV's ip address manually and now it works fine. My computer on the other hand does not no matter if I set it manually or not. Even if I plug in the ethernet cable from the base station it doesn't work. It show that it has a self assigned IP address. After I set it manually it shows that I am connected both via wifi and the ethernet cable but I can't connect to the internet. If I plug the modem directly into the computer bypassing the base station I get internet and it is using the IP address that worked originally.
It has something to do with the connection from the base station to my computer but this is odd considering every other device I have: iPhone 4, apple tv, apple tv, apple mini with retina display all work perfectly via wifi (newest apple tv had to be set manually as I stated above but now works fine). When I check the ip of the base station itself it seems to be different from the ip of the computer when the computer was connected directly to the router. I don't understand why my computer now can't connect to the internet via the base station whether it be wifi or by ethernet. Can you please help me trouble shoot this?
I have an AirPort Extreme base station which allows up to 50 users and a 30 meg connection speed.
I have a MacBook Pro (17-inch Early 2009), OS X Mavericks (10.9.2)

It has something to do with the connection from the base station to my computer
I don't think so..
I just posted a reply which totally vanished.. strange strange website now.
Please post some screenshots of your AE setup from the airport utility.. I want to see the summary page, then the network and internet tab.
Please tell us what modem you use.. is it a router??
If you have satellite or 3G wimax etc service they often are limited to 5 IP addresses... the AE takes one and then 4 more devices can join .. no more.
You need to also give us the screenshot of the IP you are getting in a computer that works.
EDIT
Sorry this is half double post.. the previous page refused to display.. now it has returned..

Can't connect MacBook (Core 2 Duo) to AExpress "N" network

Hi folks,
I have a MacBook which connects happily to my home Airport Express wireless-G network. However, my parents have an Airport Express which is a year or two newer, and theirs is wireless-N. I have searched the discussion pages here for guidance on why I can't connect to their network. My MacBook sees the N network, I have the password, but it just won't connect. At first I thought my MacBook was not compatible with N, but these discussion pages seem to say that mine should have the capability. I found something about downloading a $2 "wireless N updater enabler" software from Apple, which I did, but it wouldn't install, perhaps because my OS is already up to date? (I think the enabler update was more for OS 10.4 users?)
I have confirmed that I have Intel Core 2 Duo processor, which is a prerequisite. I confirmed that I have a wireless b/g/n ready airport card on board (I think it was the Network Utility software which showed me that).
But I can't figure out what else I need to do in order to connect to the N network.
Grateful for any help. Thanks.
-- Josh

I had this problem with my MacBook connecting to my Linksys N Router. They had me change the wireless security from WPA to WPA 2 and now it connects as 802.11n. Speed still seems a bit slow as it only connects at 72 Mbit/s but it is better than the 54 Mbit/s it was connecting at before the change...
