Two Macs, one is on the wireless network, one isnt.

To make a long story short, i have a mac pro, and a mac book pro. The router im using is a airport express. The mac book pro works no problem, and i just installed the wireless card in the mac pro, and it doenst see the router. The computer reconizes the hardware, but no internet connection. These two computers arent networked or anything. I just bought the card, slapped it in, and expected it to work like all apple stuff does. Im shure this is a redundent question, but i could not find the information i was looking for by searching.
Thanks!

OK. Could be you have to buy an external antenna option from places like
QuickerTek and others to expand the otherwise weak wi-fi range in the Pro
tower; since there are options for sale by vendors and direct online.
The wi-fi and bluetooth are said to be options in the Mac Pro; too bad the
Apple option does not include a port (then) if one is lacking to facilitate this
need to connect from the tower wirelessly to an internet access point this
wireless card and defective antenna location inconveniently provide a user.
The old option of running ethernet to the base station may be the best bet,
even if it will make that Pro slower to access data on a network than the
specfication speeds they suggest wireless transfers can run. Funny, some
one in these forums posted an image of the antenna on the back of a tower
when the question of wireless problems and the Mac Pro first came up.
I'd almost suggest it was you; but it seems like that's alot of trouble for
an arguement.

My mac is connected to the wireless network, but I still have not internet connection. How do I get the computer to connect

Everytime I move, I have to reset the TCP/IP settings. I am haveing touble getting a router number that area. Can you help?

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/Wi-Fi menu bar item to turn AirPort/Wi-Fi off, then on again.
2) Try to select your Wi-Fi network from the AirPort/Wi-Fi menu.
3) In the Network panel of System Preferences delete the AirPort/Wi-Fi 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/Wi-Fi connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease". Note that the fix this step implements may be temporary.
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.

HT1178 Do I want to create a new wireless network or join my current network? I can't connect an ethernet cable to the Mac / printer and to the wireless modem at same time - in two different rooms.

I am trying to set up Time Capsule so that I can do my first backup (after 1 1/2 years!) with Time Machine. I have read other forums, but in each case they instructions eventually do not apply.
I have connected my TC to my existing wireless router. This sits in a bedroom and cannot be moved as a rental home.
I have plugged in the TC and updated the software.
Now - do I want to A Create a New Wireless Network (remember I can't connect the TC to Mac using an Ethernet cable). B Replace an existing base station or wireless router with TC (only intend to use for TM as don't know other benefits as of yet). or C want TC to join current network.
Thinking C. If I choose C, it then asks A TC to wireless join current network (NO as already connected using Ethernet). B want to connect TC to my network using Ethernet to extend my existing wireless network. C want to disable the wireless network on this TC and connect it to my computer or network using Ethernet - CANNOT do this as devices can not be in the same room.
Or do I want to create new wireless network - first set of questions - choice A? What is the benefit to creating a new one when I won't be in this rental house for longer than 18 more months??
Please help and quickly! Thanks!

Let me suggest some things.
But first ask exactly what wireless router you have now and what type of broadband service?
Are you happy with the wireless on the current router? If so, then you can plug the TC straight into whatever computer you have by ethernet, short 1M cord with no connection to the network. And use it without affecting your existing network at all. This is trivial setup.
Although you don't say exactly what Mac and printer you are using, is it a desktop? Laptop it is definitely easier not to plug it in, but a desktop you can plug in the TC and it will all sit happily together.
How is the printer connected and to what?
I am not sure why you need such quick help.. this is all minor setup stuff.. and 18months in todays world is like permanent man.
Your multiple A, B, C are more confusing than helpful.
The best choices without more info.. are to replace the existing wireless router with the TC. ie your option B.. but how to do this depends on the type of connection. Is it cable or adsl? Can you easily bridge the existing modem router.. if that is what it is?
Think carefully in the ideal world what would you like..
and what do you have..
We can probably suggest ways and means to fit what you like to what you have.. without introducing a stack of options that are doing your head in.

Two laptops in the same place - only one connects to a wireless network

I share a room with the guy I'm working with, and his computer (older MB) easily connects to the wireless connection for a fast connection. He has full bars on the Airport icon. My older MBP took several tries to even connect to the wireless network and it doesn't get many bars. It is very slow. Is there any fix to this problem?

"Is there any fix to this problem? "
To avoid the +"been there done that"+ scenarios, please advise what troubleshooting methods you have already tried to rectify the problem.
Have you run the network or router Diagnostic test for example? Check your network and router settings?

This AirPort base station was unable to extend the wireless network.

I have an AirPort Extreme in the lounge connected to BT infinity.
I also have an airport express in the kitchen connected to a stereo system.
I have had this set up for around 12 months.
The airport express will not extend the wireless network.
I reset it, restart, factory reset etc and it will work fine for around 3 days, then I get the same error message saying
This AirPort base station was unable to extend the wireless network. Make sure the wireless network you’re trying to extend was set up and is working correctly, that you entered a matching wireless network password into this device, and that this device is in range of the wireless network.
The express is situated easily within range of the extreme. And the airplay between those two, my iMac and two apple tv's works pretty much as it should.
Can someone please shed some light on this?
Maybe I have it in a wrong setting or summut....

I am also experiencing a recent failure in my Airport devices no longer extending my wireless network.
My Aiport Express and second Airport Extreme were extending my wireless network for more than a year
The only change that has taken place lately is that the firmware for both devices was upgraded to 7.6.4, however the upgrade was only in response to trying to resolve this problem. Needless to say, the firmware upgrade did not resolve anything.
If I didn't know better, I'd have thought I wrote the above.
I have a TC from a few years ago (last one before the tower, I think), plus the older AEBS that it replaced extending the network, plus a 1-year-old Express also extending. I had upgraded them all to 7.6.3/4 when it came out, but reverted them all to 7.6.1 when everything went crapways (others having the same issues of the LAN regularly croaking), and didn't bother upgrading again since.
Today I just tried 7.6.4 on all of them, and it seemed OK at first with green lights all around in Airport Utility. Then I made one change, which was to enable 5Ghz on the main AEBS/TC only (the express doesn't need it, and the older AEBS can't do it).
The latter two started flasing amber and giving the "unable to extend wireless network" error message.
So I'm wondering if you are similarly using 5Ghz?

Size of the wireless network

Hi,
Lets say we have a company that does regular usage, surfing the web, email,occasional large file transfer, working in internal systems. Using one SSID, one VLAN, one DHCP-scope. When will you start to see bad performance regarding number of clients connected at the same time? 500, 1k, 2k clients?
When will clients broadcast trafic, like ARP, become a problem for the wireless network?
Regards
Philip

The quiestion is very loaded IMHO. Split it in two different parts and this will help you answer it:
1. How many users connected wirelessly
2. How many nodes on the VLAN that will begin affecting its performance.
1. as for wireless the main concern is amount of clients per Access Point and the amount of Clients/Access Points per Controller. One Access Point can safely handly 10-20 clients (depending on their cell size, minimum allowed data rate, average data rate and proper RF design (no co-channel, minimized hidden nodes etc).
Then remember that with Cisco all the clients traffic terminate at the controller, so having an X amount of 3600-series APs with 150-300mbps capable APs there will be a need for a backbone of that controller to handle say 20-25% aggregated traffic (and may be more depending on user traffic).
2. Is not just a wireless question as Wireless clients will be confined to their cells. I'd suggest avoind building subnets with larger than 1022 hosts (/22 bit subnet mask) and if possible using smaller subnets (/23 bit).

Need help here! I'm out of options. Computer can't see the wireless network

Sorry for the novel, but I have to tell you what is going on with my computer. I also need to vent because I’m extremely frustrated. I want to make sure I give as much info as I can we can get this fixed. I’m done with trying to figure this out on my own!!!
I’m having a major issue with the wireless network connection on my desktop. I’ve tried everything and I can’t figure out what it’s doing.
First of all, my wireless router is set up correctly (according to the Sticky), has active security, and works fine. It has nothing to do with the router. I’m sure of it.
Here’s a quick history:
When I was at my first residence in Chicago and bought a Linksys wireless N router in May 2008. My computer was about 30 feet away from the router and everything worked fine. Always found the router and never lost connection.
I moved to a new place in September 2008 and used the same router, computer, etc. at my new place. The computer was only about 7 feet away from the router this time, but I used the wireless connection instead so I wouldn’t have a network cable lying across the floor. At first everything worked fine. No issues. Then, one day out of the blue, my desktop lost connection with the router. My router didn’t even appear as an Available Wireless Network. I rebooted everything and that seemed to fix it. OK, issue fixed, right? Wrong. It did it again the next day. I rebooted everything, but it still couldn’t find my router. It did see lots of other wireless routers in the area though so I know the wireless card was working. It just didn’t see my router.
This went on for a while. Sometimes it would see my router and connect then it would lose it again. I thought maybe it was the router going bad. Well, I have a notebook computer too so I tried it. It has found my router every time and has never lost connection. I had it sitting on top of my desktop even to see if there was some sort of dead spot in my condo, but the notebook found my router just fine.
Sometimes my desktop would see my router, but it wouldn’t be my network name. It would call it “Home” or something. I know it was my network because it was the only network with maximum (Excellent) signal strength. I’m thinking it must be some sort of association issue. For some reason it doesn’t associate my router as an available network. I don’t understand that.
I tried everything: Ad Aware, Live OneCare, registry cleaners, driver updates, restore points, pretty much anything I found in the forums. Nothing worked for long if at all. It’s like my desktop only finds my router when it wants to. Note: The only thing that would work sometimes was if I clicked “Repair.” Sometimes that would work. I finally gave up and connected my desktop via network cable and unhooked my wireless card. I never lost connection as long as it was hard-wired.
The drama continues. I recently moved to Iowa and set up my network here. I’m using the same router, same desktop and wireless card, same notebook computer, etc. I went ahead and tried the wireless card on my desktop again. It worked just fine! No connection issues at all. It connected and stayed connected. I thought, “Well, that’s strange. It must have been something with the condo in Chicago. Oh well!” It worked fine from February 5 until March 10. Now it’s doing it again!!!! The notebook is about 3 feet away and sees the router just fine.
Here are the facts:
I’m using a Linksys WRT300N Wireless-N router.
I’m using a Linksys Wireless-N PCI WMP300N Adapter (about 18 months old).
I’m running Windows XP on the custom built desktop and Windows Vista on the HP notebook.
I built this computer about 5 years ago and have not done any major upgrades for 2-3 years. The only thing I added was the wireless card. I also changed out the HD in January 2009 and did a data migration right before I moved to Iowa in February. All of the networking issues were going on well before I did the data migration though so it has nothing to do with that. In fact, I had my computer hard-wired into my router at the time of the data migration and the wireless worked fine (for a little while) after I moved to Iowa. So if anything, the data migration seemed to help with my wireless connection.
All drivers are up to date.
Using Windows Live OneCare and have run complete scan: nothing found.
Using Ad Aware and have run complete scan: only found cookies and deleted them but didn’t fix issue.
Ran WinsockxpFix but that didn’t help.
Ran TweakNow RegCleaner Standard but that didn’t help.
Right-clicking the wireless icon, I try to view Available Wireless Networks. The window comes up and shows me other wireless networks in the area (2 available right now), but doesn’t show my network at all. I click “Refresh network list” and 1 or 2 of the other networks will come up, but mine is still not shown.
I’ve clicked “Repair” and get this message: “Windows could not finish repairing the problem because the following action cannot be completed: Connecting to the wireless network.”
If I go to Control Panel, there is a Wireless Configuration Utility program from Broadcom. When I open that here is what I find:
It is not managing my wireless networks.
Under the “Wireless Networks” tab I see my Network with an “X” over the router icon to the left of it and a locked security icon to the right of it.
No information under the “Link Status” or “Statistics” tabs.
The “Site Monitor” tab shows my wireless network and the other 2 networks in the area (although they drop in and out because of signal strength). My network is always present even though the signal strength bounces up and down. This tab shows that my network is secure, 802.11 is g and n, speed is 270 mbps, Channel is 9, and Signal bounces from orange/red to green. Data encryption is (m)TKIP, TKIP, WPA-PSK.
I was going to use my notebook to post this message since it has been connected for 2 days without ever losing connection. It shows Very Good signal strength and is about 3 feet away from my desktop.
Update: My desktop just connected to my network after sitting there for 2 hours. Good to Very Good signal. Broadcom tool shows the connection and now has information in the Link Status and Statistics tabs.
Cancel that. It just lost connection again. It was only connected for about 5 minutes. There is no change in signal strength according to Broadcom though. In fact, Broadcom shows better signal now that I lost connection.
Now, it just connected again (on its own) after sitting there for 10 minutes! I’ve been surfing the web on my desktop for 45 minutes now and I’m using my desktop to post this message. What the heck?!!! This is what it’s like. Aggravating huh?
Well, that’s all I can think to write. What else do you need? Can anybody help me with this?
I’m confused. Please help!
Thanks a lot!!!
Jake

Thanks but it's just my desktop that doesn't see it though. My notebook sees it everytime, even at the same exact time that my desktop doesn't see it. For example yesterday when I was typing up this post, I was typing up the post on my notebook because my desktop didn't see the router. I don't think it has anything to do with the router actually, but I wanted to see if anyone on here has encountered this issue before. Other forums have similar issues but I've tried all of the fixes I found elsewhere and they didn't work.
Any other ideas?
Thanks!

Sharing files with other members of my family on the wireless network

I would like to share my files with other members of my family on the wireless network. Unfortunately, their pcs are MS Windows OS and connected in workgroup type while I am on Mac. I can access internet via the same wireless router but cannot see other members. Can someone advise How I can accomplish it. Thanks!

I don't have personal experience with this, but I was reading this article earlier today, and it seems to address your situation. I think the solution is on page 2.

I have two Macs: an MBA and the new iMac. Is there a way to have iTunes and all the content in it identical on both machines?

I have two Macs: an MBA and the new iMac. Is there a way to have iTunes and all the content in it identical on both machines?

Yes you can copy the content to your new machine and use Home Sharing to keep the content identical
Connect the two machines via an ethernet cable it is 3 times faster than Wifi. Turn wifi off on one machine to enforce ethernet connection
In System Preferences, Sharing turn on File Sharing
Then
Copy the music/itunes folder from the Macbook pro to the music/ folder on the imac
Both machines should now have the same library
Disconnect H the ethernet cable
Set up Home Sharing and under Settings at the bottom of the Home Sharing page. Select to transfer new purchases.
Do the same on the other machine.
Then when you r machines are connected by wifi and each time you start itunes it will transfer your new purchases
Setting up home sharing

Mac Pro connects to the G network on my dual-band instead of N

Hi. My Mac Pro keeps connecting to the G network on my dual-band instead of N. I can confirm the network/router are fine because my Mini connects to the N network fine, on the correct channel and at 270 Mbit/s.
I'm using a NETGEAR RangeMax Dual Band Wireless-N Router. It is capable of simultaneous N and G networks as well as 2.4Ghz+5Ghz.
I've tried every channel and combo. Very occasionally the Mac Pro will register the N network 270 Mbit/s but will drop back to 54 Mbit/s.
More evidence, AP Grapher reports that it is using the G channel (eg 9) instead of the N channel (eg 43).
I also tried a Netgear DGN 2.4Ghz wireless-n router with the same result. That router only runs N, and only at 2.4Ghz, but Network utility reported that it was usually connected at 54 Mbit/s instead of 130 Mbit/s.
Combined with the fact that the Mac Mini works fine suggests to me that my network card is faulty.
Any suggestions before I lug this big beast back to the store for a new card?
Thanks.

I believe I've solved the first problem. The router gave both networks the same SSID by default. I have now set them to
myname-n
myname-g
I can now choose either network and the link speed is reported as 270 Mbit/s or 54 Mbit/s respectively.
However, I can still only achieve peak transfer speeds of 2.8MB/sec and AP Grapher reports 41/270 Mbit/sec unless I switch to 2.4Ghz only, in which case I can achieve 52/130 and 4.3MB/sec, well below 270 Mbit/s or even 130.

Why doesn't my MacBook Air see a connected printer on the wireless network?

For some reason my MacBook has come up with a case of the stupids. I have been able to print out to my Canon printer before, but now it doesn't see it. The printer is on our wireless network and can be seen by our iPad, and iMacs but doesn't appear on the MBAir. I have reinstalled the drivers, rebooted the system and when I go to the Preferences to look at the Printers/Scanners there is nothing there. Pressing the + button comes up with a screen with nothing in the default area. The Air is connected to the wireless network and operates fine with the internet and other operations.
What can I do to fix this?

Hello gregfrommi,
After reviewing your post, I have located an article that can help with printing in Yosemite. It contains a number of troubleshooting steps and helpful advice for the issue you are experiencing:
OS X Yosemite: Printing troubleshooting
Check the network
Open Network Diagnostics, then follow the instructions to make sure you’re connected to the network.
If you’re using a Wi-Fi network and there are multiple Wi-Fi networks available, your Mac and the printer might be on different networks. Open the Wi-Fi menu in the menu bar, then try choosing a different network.
To see if the printer you want to use is on the same network as your Mac, open Printers & Scanners preferences (choose Apple menu > System Preferences, then click Printers & Scanners), then click Add . If the printer doesn’t appear in the list of available printers, your Mac might be on a different network.
If you know the printer’s IP address (for example, 192.168.1.100), you can try adding it as an IP printer. For more information, see Add or remove a printer.
If your printer is connected to a Time Capsule or AirPort base station, disconnect your printer from the Time Capsule or base station, then reconnect it.
Make sure you have the latest software
Make sure you have the correct version of your printer’s software (also called its printer driver).
If you’re using a printer that another user is sharing, make sure you’re both using the same version of the printer software. To find out which version you’re using, open Printers & Scanners preferences (choose Apple menu > System Preferences, then click Printers & Scanners). Select the printer in Printers & Scanners preferences, click Options & Supplies, then click General. Note the driver version.
If you’re using a network printer or a printer attached to your Mac, make sure you have the latest version of the software for the printer. If you still have problems, try different printer software for your printer.
If you’re using an AirPrint-enabled printer, you can check with the manufacturer to see if there’s a firmware update for your printer model.
Replace a corrupted printer queue window
If none of the previous solutions work, the printer’s queue may be corrupted. Open Printers & Scanners preferences (choose Apple menu > System Preferences > Printer & Scanner preferences), then delete and set up your printer again.
If you still can’t print, reset the printing system.
Print documents
Reset the printing system
Add or remove a printer
Thank you for contributing to Apple Support Communities.
Cheers,

Ethernet port as a bridge to the wireless network

*Is it possible to use an Ethernet port in MacBook as a bridge to the wireless network* and connect another device to it that will have access not only to the Internet, but also to other services, eg. files on another computer connected to the network wirelessly.

The short answer, would be Yes.
The longer answer requires setting up the computer in the correct
way to do so; and hope that any advice to going there was followed.
And knowing more about your hardware situation may yield better
or easier answers; a better solution to using all the computers.
You can share a network connection through use of settings in the
appropriate System Preferences panels. Other sharing preferences
would probably have to be checked and if necessary, changed.
I never change anything that just works, without good reason, and
so far, since I have no need to share between my computers by wire
or wireless, I have not done so. I do have files on external hard drives
and on USB Flash Drives, and can put stuff on CD & DVD media.
Given that, I don't network my computers over AirPort, Ethernet, or
by FireWire, etc. But others here do. Your HelpViewer in the Mac
can tell you how to network or share internet over ethernet, etc.
More information on your situation is needed to propose answers.
PS: Information you posted in another location would be relevant to
getting a reply here, too... in reference to this post:
