Airport card giving constant communication timeouts on wifi network connection attempts.

I have an old Macbook with OsX 10.6.8. The Airport card in the macbook is giving me communication timeouts when trying to connect to my WiFi Netgear router (802.11n). It sees the network and requests password but fails to connect. Any ideas? Thanks.

Do the older AirPort cards only work in wireless B, not G?
Yes, the original Airport card was 802.11b only, later Airport Extreme card was b/g.
The typical peak throughput (sustained data rate) of an 802.11b wireless connection under ideal conditions for end user data is actually 4-5 Mbps. This level of performance assumes a wireless client in very close promixity (within a few meters) of the base station or other communication endpoint. Due to the distance-sensitive nature of Wi-Fi signaling, 802.11b throughput numbers will decrease the client moves further away from the base station.

What should the"default behavior" be for WiFi network connections?

I Have been able to at least temporarily fix the plethora of problems encountered after downloading Mountain Lion to my 2009 17" MBP just ten days ago. Thanks to the time and effort of so many posters that are much more savvy than me, I successfully executed the steps suggested in many of the posts and with good results. It surely beats running down to the Apple store and being told that I am the only one with a problem.
Okay, I've realized that I don't really know what the default behavior of the WiFi network connection should be?
Specifically:
Should the Wi-Fi drop down in Network always be" looking for networks", even though I am obviously on my Network?
Should the Wi-Fi be connected at all times even when your computer is in sleep mode- or deep sleep mode? There have been so many problems with Wi-Fi dropping off,slow or hanging loads, etc.
I unchecked "ask to join networks, in Network preferences thinking it might stop looking for networks when it doesn't need to because I'm already on mine. I do see my neighbors (four neighbors) in the drop down in Network.
How do you get into Time Capsule's settings, to check speeds, especially ping? What should the ideal settings be?
How do you know if your DHCP license is renewed? I've heard that feature isn't working and may be the culprit to some of the Wi-Fi problems.
I'll look forward to your help in understanding more about this. I've been in the support area a lot lately, I've read plenty of definitions, and explanations of the different options to choose from in Apple's support area, but nowhere have I seen anything that explains what the default behavior should be or perform like.
Thanks, as always.

Generally, you don't want to tweak the wifi settings. It pretty much takes care of itself. The caveat to that is, of course, if you're experiencing problems.
The 'looking for networks' behaviour only happens when you log in, wake the mac from sleep OR when you click on the wifi icon. You clicking on it tells the mac "I want to see what networks are available" - so it does a scan for you to check to see if any new networks have appeared since you last clicked on it (or woke/logged in). In short, if you don't want it to look for new networks, don't click on the icon!
Unchecking the 'ask to join networks' option only applies when your mac detects a new network (such as when it wakes) that you haven't already authorised; it'll ask you to confirm whether you want to join it or not. Otherwise, if the network is open it'll join automatically. You should keep this selected if you travel around with your Mac. It's a good idea to know what network you're on before you start plugging in passwords or typing other things into the mac.
There is a utility that you can use for ping and traceroute called 'Network Utility'. Click on the Spotlight icon in the top right of your screen and type "Network' and you should see it at the top of the list. Hit 'return' to open it.
DHCP licences are normally renewed automatically by your router every 24 hours. Again, there's no reason to be messing about with that unless you're experiencing problems.
If you're experiencing wifi dropout, let us know, and we'll make some suggestions, but if you're not, you're best leaving your mac to manage the background processes. It knows what it's doing!

Can I use the airport card in my macro to extend a network?

I've looked into extending a wireless network using an airport express, etc, but I was wondering if I could use an airport card in my Mac Pro to do this as well?
I realize I should be able to 'share' as a hotspot, but would prefer to extend an existing (or new) network instead.
cable modem----> airport or TC -----> Ethernet ----> Mac Pro -----> internal airport card (extends wifi network on airport or TC)
Thanks,

System Preferences > Sharing > Internet Sharing ...
can allow you to declare that your Mac Pro now includes simple Router functions that offers WiFi service to nearby devices. It has some limitations, but DOES offer DHCP to those devices.
When configured in this fashion, the Address assigned to the port on your Mac Pro is not a meaningful indicator of whether it is working properly -- that will be a self-assigned IP address in the range 169.254.xxx.yyy. The important address is the one provided to the WiFi devices, which is often 192.168.1.1.
Only the base channels 1 to 11 will be offered. Only WEP encrytion is offered. So if you already have lots of nearby Routers, this option is not that helpful.

Airport on computer does not see any wifi networks

Airport worked fine until recently and worked fine when I installed new OS a while back. I can see no wifi networks including my Airport Express. My other Mini sees it and others as well as my MacBook so it seems to be an issue with that computer.
Sometimes I can log into my network by choosing Join Other Network but sometimes it doesn't work like now. Earlier today I logged in in this method and then it dropped out and I haven't been able to connect again. Any suggestions as to what the problem is?

Yes, I had thought of that too. Just wanted to avoid buying another card without being sure of the problem.
I've now tried setting up two routers to the 5GHz band, and sure enough, they both work and their wifis are picked by the macmini. All the other wifi networks I see around my house seem to be 54g.
So it seems that only the b/g part of the macmini's wifi card is broken, while the n part is working properly. Do you know if this is possible or if there is a configuration in the macmini that is forcing it to only use the 802.11N?
Thanks for your help anyway!

Can an older Round Airport Extreme and Airport Express be used on my home WIFI network?

I recently upgraded my Macbook Pro to a newer one because I was having problems with the older one getting on my home WIFI network. It had been dropped, but had continued working without any hiccups for five or six months. Suddenly it won't go online. It said there was no WIFI hardwae installed. I suspect that the WIFI antenna connection between the main bdy and the display failed. Repair options at the Apple Store were iffy, so I just baought the new one. My Time Machine backup smoothly cloned my old machine onto the new one.
In the "when it rains it pours" category, my Airport Extreme also failed at the same time I began having problems with the old laptop. Suspecting the hardware was the problem after checking with my ISP, I purchased a new Airport Express at Best Buy. Using it, I got my WIFI network back up and running. That's why I figured there was a problem with the older Airport Extreme. The Airport Extreme was replaced by an Apple Genius at the store, when I purchased the new laptop. Putting my Home WIFI network back together with the new AE, went fine, but it turned up another problem. I use an older (pre-N speed) Airport Express to link a YAMAHA digital piano wirelessly to my WIFI. It can go online directly and download music. I can also push my iTunes wirelessly through the piano's amplifier and speakers for great sounding stereo. The problem is my new AE won't recognize my older Airport Express. I tryied downloading the Airport Utility v. 5.6 as suggested online, but It still won't find the Airport Express hooked up to the piano.
Is there any way to update my earlier Airport Express and also an older Airport Extreme (round)? The Airport Utility v.5.6 won't recognize them and initialize them. Any ideas? I repurposed the new Airport Express I bought to seerve my printer, allowing me to disconnect the USB cable from my iMac. That's working fine, except my HP OfficeJet Pro 8500 now won't give me two sided printing anymore. It always something!
Network consists of:
20" Mid 2007 iMac running Mac OS Lion 10.7.4
New 15" MacBook Pro running Mac OS Lion 10.7.4
HP Officejet Pro 8500 All-in-one Printer
New Airport Extreme attached to DSL Modem
New Airport Express wirelessly attaching my Printer to the network
Old Airport Express (A/B/G) connecting my Yamaha Digital piano (NOT WORKING)
Old Airport Extreme (round) (NOT WORKING)

Bob,
Thanks for your help. At this point, I'm seriously considering replacing the older "g" AX with a new "n" model. For whatever reason, each time I've tried to bring the ols AX bcak online in my network, it only managed to screw up my network. Using the Airport Utility 5.6 for Lion, I was able to get a green light on the AX, but it still would not go online from my Yamaha digital piano control panel, like it always did before.
Using AUtil 6.0, everything else works, and I'm assuming that setup with a new "n" speed AX, my piano will be able to get back onlune, too. When I originally set up the AX to link the piano to my WIFI network, I had very little trouble getting it setup. YAMAHA didn't list the Apple AX in it's list of compatible wireless routers/adapters, but I saw no reason that it wouldn't work. As I said it was a reasonably easy setup the first time, and it has worked for several years with no problems.
It's not the cost of buying the new AX that bugs me, it's the fact that I can't figure out why it won't work now when it did before. It was working fine with my old AE based WIFI network, even after upgrading the my computers to the Lion OS. I used to be reasonably savvy with Apple technology, having spent the last 15 years of my teaching career (1987-2001) as the tech liason for the schools where I worked, supporting first Apple II's, then Macs, and networked buildings. After eleven years of retirement, I find it harder and harder to keep up as the technology just keeps evolving. I'm trying, but it's not easy! Any and all help is appreciated!

"No airport card is installed" when power adapter is not connected

Hi
I am getting the "No Airport Card is Installed' message whenever my Macbook Pro does not have the power adapter connected. When the power is connected everything works fine. If it is disconnected, the airport icon turns grey, airport disappears, and I can't turn on airport anymore.
Thanks

Hi, and welcome to Apple Discussions.
Are you using an original AirPort card and not an AirPort Extreme card? The AirPort Extreme card is not compatible with a G3 iBook and installation of an AirPort Extreme card can, in fact, damage the iBook's logic board beyond repair.
Are you following the installation instructions, as outlined in this Apple Knowledge Base article?

"airport card not installed" and can't open network preferences

I was earlier having the problem of no ip address and not connecting to the Internet and self assigning an ip address. I tried everything to fix that and on my last attempt I turned off the airport and shut down but now it says I dont have an airport card installed. How do I fix this?

Your running snow leopard which may be the case. Probably not but i recommend doing a clean install of snow leopard if the problem perrsists.
Also I suggest going to the apple store anyways. I personally enjoy finding help on the forums but sometimes if you book in advance going to the apple is a whole lot simpler.
You might also want to try upgrading your operating system to Lion or Mountain Lion which may fix the problem.
Yet another option would be to open up the laptop (Voids your warranty) and check is the airpot card is loose and maybe not being recognized.

Are LAN ports on Airport Extreme active when used to extend WiFi network?

I am thinking of buying an Airport Extreme to wirelessly extend the dual-band WiFi network from my Time Capsule. In this scenario, with the Extreme configured as a bridge, would I be able to use the LAN ports on the Extreme to join some AV kit to the network?
Thanks ... Simon

How can I avoid Thunderbird timeouts when switching network connections?

I'm using Thunderbird 24.4.0 but this problem goes back many releases.
This problem happens when I switch from an external WiFi network to my company's internal LAN (ethernet).
I'm connected to the company's email server via WiFi from home and can get and receive email no problem. I then turn off the WiFi, put the laptop to sleep, take it to work, wake it up, and plug in the Ethernet cable. I click on Get Mail and in the status bar at the bottom it says "Connecting to [servername] ..." and stays that way until I get a notification that Thunderbird timed out. I click on Get Mail again and this time it says "Connected to [servername] ..." and it gets my email. (It may have briefly said "Connecting to" prior to "Connected to" but I think I've only seen that once.)
Why does it never work the first time but has to timeout before it will successfully connect, and what can I do to get it to connect without having to go through a timeout cycle?
Thanks,
--Steve

How to setup a Linksys router as WiFi network -- connecting to Actiontec

With horrible range using the Fios Actiontec router, I went ahead with google searched suggestion to use a second router as my WiFi network. Unfortunately, I can't figure out how to properly set up the second router to the Actiontec even with step-by-step instructions.
Can anyone give me step by step instructions to get the second router up and running? Please help!
I wish to set up my second router as a new static connection so my WiFi devices may connect to that network instead of the Actiontec's. I do have Fios TV, so I need a solution that will not interrupt the other services.
I used this set of instructions:
http://smallbusiness.chron.com/set-up-second-router-verizon-fios-60493.html
I put the starting IP as 192.68.1.3
I got up to the input New Static Connection and input 192.68.1.2 and the MAC address of the new router.
When I press Apply, I get the message,"The IP address 192.68.1.2 is illegal for any of the connections subnets." The first time it failed, it stated that the address was used, but now I get this message every time.
I also attempted this set of instructions:
http://www.ehow.com/how_6127815_set-second-router-verizon-fios.html
But I only got up to #6 where I connect to the new router and enter admin. I was unable to access the new router. My browser states that there is no internet connection.
Note: Verizon support has been no help so far. I am at wit's end.

These are the instructions I would use
Can I use my wireless or an extra router along with the Verizon provided router?

TS1398 Ever since I upgraded to iOS 7, my iPhone is constantly forgetting my wifi network connection.

Lately, my iPhone has been getting dropped from my wifi network and more often than not, when I leave and come back to the office wifi, the phone will have trouble connecting, asking for the password again and again (which it should already know!).
But now it will not connect at all. The wifi is working fine on my mac and the signal strenght is fine. I have gone through all of the steps suggested by Apple support and it still will not connect to the wifi network.
Any help?
