Unable to connect via airport all of a sudden

Unable to connect to the internet via airport all of a sudden. No changes to modem or router or network settings of macbook etc. Other devices in the house can connect just fine, but called cable support to verify and all is fine on the DSL end. Cannot download updates w/o internet connectivity. Have tried going thru the motions of setting up airport again and cannot get past the DHCP (can't remember exact letters at the moment) as my carrier is not a PPoE. Aside from reinstalling the OS to see if that will fix, does anyone else have any suggestions? Apparently this happens more often than I thought based upon other posts. Thank you!

Thank you for your help and it was a big help. I removed Norton software firewall, and firefox began to work. I thank you for your help and suggestion.

Internet connection via Airport Extreme/router thats not working, why?

I have been having problems with the internet connection via Airport Extreme which I find it a bit unusual and its still driving me nuts! This is what happened:
I have lost my internet connection last Sunday evening upon my return from a weekend away from home. The last time I have used the internet connection on my macbook was the previous Friday morning. Prior to the apparent disconnection on Sunday, I have always used my internet connection wirelessly through Airport Extreme (that is connected via ethernet cable to the NETGEAR DG834v2 ADSL modem which had worked beautifully until the problem arose on my return). This wireless internet connection allowed me to surf the internet anywhere in my home.
However, upon the successful re-connection to the internet via the modem router, I have discovered several new problems. I have tried to set up the internet connection wirelessly again but instead the following happened:
1. Router (Netgear) drops ADSL connection and cannot reconnect when connected to airport via Ethernet. (which is the case when using airport wireless).
2. Router connects to ADSL fine when computer is connected to it via Ethernet. (However, router disconnects when magsafe power adapter is taken out for some inexplicable reason!)
3. Router connects to ADSL fine when nothing is connected to the router (ie. No Ethernet connections)
4. Router connects to ADSL fine when connected to airport via Ethernet and computer is connected to airport via Ethernet.
So from the above, I cannot connect to the internet properly whether wirelessly or not so I suspect it could be faulty router or could it be airport extreme? I have asked my ISP for an explanation and all they have said is that it cannot be the mis-configuration but could be to do with the power adaptors or the way plugs are set up and suggested I take out all the power plugs (and power surge protector) out to switch everything off, the macbook, router, printer and airport extreme. However, when I have re-plugged them all back in, the problems I have described above still persists!
Would appreciate any help if anyone here recognises why this is the case and what seems to be the cause of this. If so, what should I do? Though I have written back to my ISP again yesterday for more help so im waiting to hear from them...
Thanks

I receive a not connected to the internet message several times daily on my iMac connected via airport to a time capsule which accesses the internet via cable modem.. When I input my password to enter network preferences, the connection re-establishes.

I receive a "not connected to the internet message" several times daily on my iMac connected via airport to a time capsule which accesses the internet via a cable modem. Software/firmware is up to date on the iMac (OSX 10.6.8) and Tme Capsule(7.5.2). Browser is Safari 5.1.
When I input my password at the prompt to enter network preferences, all the lights go green (ie... ethernet, ISP etc.) and the connection re-establishes immediately and states "the connection appears to be working normally".
It more of a nuisance than anything and seems to have started ocurring over the past couple of months. I also have a windows XP box also connected to the same cable modem that I never have internet connectivity issues with. I've verified all the physical aspects of the connections and can't see any evidence of any actual drops in the modem logs. I suspect it is just an intermittent communication loss between the Imac and the Time Capsule, but I am not very familiar with Mac equipment yet.
Just wondering if anyone has experienced a similar problem and what you did (if anything) to resolve it?
Thanks.

The AirPort Express will connect to your existing wireless network if the network is using WPA2 Personal or WPA/WPA2 Personal wireless security settings.
So, it can join the network as a client and then provide an Ethernet signal to your Time Capsule.
Be sure to configure the Time Capsule to operate in Bridge Mode so that it will be operating on the same network.

Slow internet connection via AirPort on MacBook running 10.5.7

The internet connection via AirPort on my MacBook is frustratingly slow, and I have no idea why.
I have an AirPort Extreme connected to a Virgin Media cable modem, a new iMac and a two year-old MacBook, both running 10.5.7. No problems at all with the wireless connection on the iMac - I get the full near-10Mbps download speed I'm paying for, despite the fact it's at the other end of the house. Not so on the MacBook, where I get barely 2Mb, even if I'm sat next to the router.
I've had other AirPort problems since the 10.5.6 update - notably one common to a lot of people on here, it seems, of the AirPort dropping the wireless connection every 2 mins. This was only 'fixed' by the fairly drastic workaround of essentially abandoning my user account and connecting via a different one.
For the slow internet problem, I've tried resetting the PRAM, turning off my cordless landline phone, changing the wireless channel - to no avail. I can't test the wired connection as my MacBook doesn't recognise my Ethernet port, it would seem, and hasn't for a long time.
Can anyone help? Thanks in advance.

I assume that you meant NVRAM as PRAM is not used with Intel-based Macs. Regardless, network settings are not stored here and resetting it won't really help. The fact that your MacBook is not recognizing the built-in Ethernet port is telling me that may have an issue with the system board ... that may be showing up as poor performance with the AirPort as well. I suggest that you take your MacBook in to your local Apple Store to have them take a look.

Printing problems with HP 1012 connected via Airport Extreme - resolved?

I originally posted on this issue in a long-running discussion on HP printer issues.
http://discussions.apple.com/message.jspa?messageID=10109788#10109788
Problem: Upgraded iMac 10.4.11 to 10.6 Following upgrade everything seemed fine except that the HP 1012 connected via Airport Extreme was not responsive. The system knew the printer was there, had installed the proper driver for it.
Intermediate troubleshooting: I tried to use Airport Utility to check the AE. It timed-out when trying to retrieve the AE setup specifications. I tried to update the firmware (7.4.1 to 7.4.2); system timed-out after a very long several minute "search for new version of the firmware."
Apparent solution: (any of the following may have made the difference - sorry not to have been more systematic)
a. I turned off AP on the iMac.
b. I unplugged the AE base station for one minute+, then re-powered it.
c. I opened my MBP with 10.5.7. Started up Airport Utility.
d. I renamed the base station. Left all other settings alone.
e. I installed the 7.4.2 firmware upgrade.
f. I ran Preference Repairs on the iMac (though I had done this right after installation of 10.6)
g. I turned on AP on the iMac.
Result: Almost immediate connection to AP, printer quickly began printing several of the test documents that must have been waiting in queue.
Too early to tell if I will have any further problems if if it permanently fixed.
Thanks to the several messages in both Printer and Network categories that suggested one or more of the above steps.

I hooked up my wife's Deskjet 5150 to my mac via USB. Since the 5150 does not have a driver from HP to work in SL. I decided to us the generic Gutenprint v5.2.3. For the heck-of-it, I picked, HP Deskjet 5550-Gutenprint v5.2.3. It prints. and the utility works, BTW, I am low on black ink.
I also tried the other printer drivers labeled "any printer name"-Gutenprint v5.2.3. and they all worked with the 5150.
So now that I know that the 5150's will work via USB with SL, I will now upgrade the other two laptops in my house to SL.
How to:
Turn printer on.
open System pref/ printer-fax/ add printer
Select hp desktop 5100
(name: -- Change name if you want - I kept " hp deskjet 5100"
Location: Your computer
Print Using: open dropdown box, select printer software. Type in: " Gutenprint" or "deskjet". I picked the HP Deskjet 5550-gutenprint v5.2.3. but I do not think it matters as long as it is a -gutenprint v5.2.3 driver.
Select OK

G5 & PC NOT STAYING CONNECTED VIA AIRPORT EXPRESS!

I've got a G5 and a PC - Hoped that Airport Express would allow both to access internet (via cable modem).
The connection drops after a little while. Everything says its working but obviously it's not.
ANY HELP??!!!
Thx!

I have white Macbook (802.11g capable) and Airport Express (802.11g capable).
I have a LAN internet connection, which is pretty fast. When I connect the cable to my ethernet and try to download something (for instance, speedtest.net) then the download speed is 33Mbit/sec, and upload is 20Mbit/sec.
I also have an Airport Express router - the 802.11g to be specific. So in the Airport Utility, under Wireless I selected "802.11g ONLY" and selected 24Mbit/sec Multicast rate.
When I tried to download something when conected to my Airport Express router - what actually happened, is that my computer is 2 m away from the Airport Express and the max download speed approximately should be ~24 Mbit/sec, but it turns out that the down speed is ONLY 14 Mbit/sec and the upload speed is 11 Mbit/sec.
So it means, that the Airport Express actually cannot deliver the 24 Mbit/speed.
I am actually pretty dissapointed, because I was kind of okay with the fact that I will loose those ~10 Mbit/sec from my actual internet sped when connected via Airport express, but I did not expect that it would be halved.
Any solutions?
According to one source, the maximum throughput of 802.11g is 25 Mbps. That assumes ideal conditions. To learn more about those conditions in your case, launch AirPort Utility, double-click on your AirPort station to enter "Manual Setup" mode, select the "Advanced" panel, click on the "Logs and Statistics" button, then click on the "Wireless Clients" tab. There you will see values for signal and noise. The closer those two numbers are together, the worse throughput you can expect.
If the value for noise is high, you might try setting your AirPort unit to a different channel.
All the above is based on your having no other Wi-Fi equipment.

Connecting via AirPort Express: Performance Help Needed.

Hello,
I'm grateful for ideas, instruction, pointers to threads I may have missed re: improving performance/determining the cause of poor performance when connecting via AirPort Express.
The deal: Up to 6 devices are connected to our AirPort Express. Only three of these are ever used simultaneously, though all remain "on," in either sleep or hybernate mode. Performance across the network is terribly uneven. Current data rate stats (a snapshot by way of the AirPort utility, in order of distance from the router):
iMac: 130 Mb/s
Printer: 54 Mb/s
Macbook Pro: 144 Mb/s
iPhone: currently "off"
PC (Connected via Belkin USB-type Wireless Adapter): 2 Mb/s
iPad: 39 Mb/s
Note: the Macbook Pro is often located in a room farthest from the hub, some 120 feet away and with partial direct line of site. Still, its performance is unimpeded.
At first glance, logic would dictate the worst problem is on the PC and caused by the Belkin adapter. But I've swaped that out for different USB solutions. Performace is seldom improved.
Wondering if:
a) The PC problem is in the data transfer rate of the PC bus. (Foregive me if I'm using "bus" incorrectly here. I'm guessing you'll know what I mean.) Or is it the nature of the USB adapters?
b) Please also note that the Printer, which sits close to the router, often has a drop in data rate, sometimes to the single digits.
Again, I'm grateful for ideas, instruction, or pointers. Also for wisdom on "extending" the network, perhaps by adding another AirPort device. I'm rather clueless about such stuff.
Thanks in advance- Best for the weekend-

Thanks,
I'm pretty sure the card is seated properly (it works most of the time after all). I couldn't get it to work when I installed it because it wasn't seated properly, I pushed it in as far as it could possibly go and it has worked since (except after extended periods of use). The Airport express is three feet from the eMac with only a couple of bits of wood between them. The connection does not go down at times which I can link with the use of any particular appliances (When the eMac stops working, the iBook is always fine, even in a similar position). It is the apparently time-dependent aspect that I can't figure out (I only notice it on those, fairly infrequent, occasions when I am online for a few hours at a time). The eMac discussion group is a good tip. Ta.

Unable to connect to Airport Extreme since installing Mountain Lion

Unable to connect to Airport Extreme since installing Mountain Lion. If I go to Finder > Shared I can see it listed but then when I go to connect to it won't. I can see it in Airport Utility and connect to the internet but when I try and connect to the base station to use my hard drive / printer it won't connect?
Tech Support tried saying it could be the devices attached don't have an update for them yet but doesn't explain why I can't connect to the base station. In their defence I can see it in airport utility so the base station does work with the OS X
However I've just tried connecting by an ethernet cable and connects fine?

Ok .
Power down the base station (Mine is connected to a 4 way so i down powered base station, printer and hard drive) powered back up and now when I go to finder then look at the shared section I can view my files on the base station.
Hope this helps

Internet speed slows down when connected via airport express

Internet speed slows down when connecting via airport express. When connecting directly via the timecapsulethe internet speed is ok, when connecting via the airport express the speed slows down.What can I do to change that? Any suggestions?

Turn off the AirPort Express completely as a test, and move your computer very close to the location of the Express.
As I said before, the Express can only extend the bandwidth (speed) that it receives from the Time Capsule, so the speed that you see there with the Express powered off will be the fastest speed of which the Express is capable.
The Express will make the signal go further when it extends....but it will not make the signal go faster.
A good location for a device that extends wirelessly is a point that is about half the distance from the Time Capsule and the general area that needs more wireless coverage.
If you locate the AirPort Express too far from the Time Capsule or there are more than a couple of walls in the signal path, the signal will be very slow by the time that it reaches the Express....and the Express simply extends a signal that has already slowed down significantly.
If you already have the Express located about half the distance between the Time Capsule and general area that needs more wireless coverage, how many walls, ceilings or other obstructions are there in the signal path between the Time Capsule, the AirPort Express and the area that needs more coverage?
Often, due to obstructions, it is just not possible to achieve good performance when you try to extend a network wirelessly. The solution is connect the AirPort Express to the Time Capsule using a wired Ethernet connection.
There is virtually no signal loss with this type of connection, so the Express can be located exactly where it is needed and it will produce a much faster wireless signal in this type of setup.

Share airport connection via airport

Can I share my airport connection via airport?
I can barely get aiport signal in my hotel room with my macbook, but my iphone cannot find any networks. Can I use my macbook pro as a bridge?
If I cannot do it with leopard sharing, is there a third party application that can allow it?
Thanks a lot!

Yep, looks like you cannot share from Airport to Airport.
See if the hotel can provide a wired Ethernet connection for you or change your room to one with better reception.

10.5.2 - cannot print with Samsung CLP-510 connected via Airport

After 10.5.2 Leopard upgrade, the printer Samsung CLP-510 prints only if it's connected directly to my MacBook (or my PowerBook), not if it's connected via Airport (Extreme): the printers become soon busy and give the message "Device busy, please retry...", and after some time the printer print an error page with "timeout" error.
No luck resetting the Airport.
Any workaround, please?
Thanks in advance
Salvo

These steps may help:
1. Open System Preferences and click on the "Print & Fax" icon
2. Click on the "+" button to add a printer
3. Click on the "IP" button in the toolbar
4. Choose "HP Jetdirect - Socket" from the "Protocol" option menu
5. Enter the hostname or IP of the Airport base station in the "Address" field - typically 10.0.0.1 or your base station name with ".local" on the end
6. Leave the "Queue" field blank
7. Replace the auto-generated name with something meaningful to you in the "Name" field
8. Choose "Select a driver to use" from the "Print Using" option menu, and then type in the model number for your printer to locate the corresponding printer driver
9. Click "Add" to add the printer, then try printing
If you report back with your results, it would be appreciated.

Powerbook G4 can't connect via ethernet but connects via airport

We have a small office network connected to an Efficient Networks DSL router that's managed by our isp. The router has 4 ports and a linksys 8 port switch is connected to one of those ports. Another D-Link wireless router/switch is connected to another port.
2 i-macs connect without problem via ethernet cable. They are set to DHCP and get 192.xx private addresses. Both run 10.4.5. Another older imac running 9.2.2. also has no problems.
I recently purchased a powerbook G4 and it will not connect via ethernet to the Efficient networks router. At first it was connected to the linksys, so decided to connect it direct to the Efficient Networks router. With DHCP, it acquires a 169. internet address which is self generated (i.e. no real connection). I tried to give it a static private address (talking to the isp provider). They could see the powerbook but saw all zero's (presumable mac address). By the way the Powerbook works perfectly at home connected via ethernet cable to a D-Link router connected to a cable modem so it's not a physical problem. I even checked the ethernet cable I used in the office with another computer - no problem.
When I switch to airport in the office, the powerbook connects to the network and the internet. I get some strange warning messages showing the server's and the router's private ip addresses. I click ok, and the powerbook finds an unassigned private ip address. It's the only way it will work, but it causes problems, because I can't connect to one of the network printers. Speed also isn't great.
Can anyone give me advise how to proceed. I am no expert on this stuff so keep it as simple as possible.
Tks

Tim,
Thanks for your help. Here's what I've done before reading your e-mail. The D-Link DI-524 wireless router is connected to the Effiicent Neworks DSL router as you mentioned. One ethernet port of the EFF.Net. router is connected to the WAN port of the DI-514.
Because I have a D-Link router at home which works flawlessly with my powerbook, I decided to connect the ethernet cable of the powerbook to the D-Link which has 4 ethernet ports. Lo and behold, the powerbook acquired a private ip address and connected to the LAN and internet!
When I connected the powerbook direct to the Efficient Networks router, it could not communicate. I believe that there must be some software incompatibility between the powerbook and the Efficient Networks router. By connecting to the D-Link, the D-Link assigned an ip address to the powerbook, and it could connect to the server, lan, etc..
Only problem is that I have a Brother network printer that cannot connect to the powerbook. My powerbook cannot find it on the network. Because there is a linksys switch connected to the efficient networks router's third ethernet port, maybe as you said, going through the D-Link via DHCP (when the Linksys is also acting as a DHCP server, might cause this type of problem. What do you think?
As a final note, other imac G5's connected to the linksys switch (which then connects to the Efficient Network's router) have no problem connecting to the lan or internet and have no problem connecting to any of the printers. When I put the powerbook on that switch, I could not connect to the internet - i.e. whether connecting via the lynksys switch or direct with the efficient networks router - same results: no internet connection whether manually or via DHCP.
So the imac G5 has no problem with the efficient networks router but the powerbook G4 hits a brick wall. The G4 likes the D-Link router. I am concerned (and I will have to check this) that if I turn off the dhcp server feature from the D-Link, that whatever software issue crops up between the powerbook and the Efficient Networks router, will rise up again, because the D-Link will act like a simple switch (just like my linksys switch), and we'll be back to square zero. In any case, no harm in trying. This may be the cause of the Powerbook not seeing that Brother printer (even though it sees another printer and other macs).
Having spent hours reading about network problems, I think it's safe to say that macs have problems with certain routers. Why a G5 works and a powerbook G4 doesn't is beyond me, but clearly software must play a role.

Unable to connect via wireless, printer is online.

I am using a Photosmart plus 209a via wireless. There are 3 notebooks connected. 2 will print but my Dell Studio (Win 7 Pro) will not. It was previously connected but now unable to connect. I have uninstalled all components using level 3 twice. Have used the Print/Scan tool. Downloaded the full SW package and the Basic driver SW. I process a job and it gets to the spooler and then "print job failed". I can view the control panel via IP address. I can view network settings and print wireless test page through HP Solution Center. Why am I unable to connect? I was able to use via USB but this is not an option.

It sounds like there is something different on the Dell Studio since it works from two other computers on the same network as the Dell Studio. It also sounds like you are able to access the EWS of the printer by using its IP address.
Are there any other errors messages regarding the printer? If so, what are they?
Is there a third party firewall installed (e.g. Norton, Kasperksy, BitDefender, etc.)?
Is this Windows 7 Professional 32bit or 64bit?

PowerBook G4 - 12" can't connect via AirPort (WiFi)

For 18 months I've had WiFi at my home and I connect my MacBook (OS X 10.5.6), my iPod Touch; my daughter connects a PC running Vista! I used to be able to connect my PBG4-12" running Tiger 10.4.11 - but today I was trying to connect and it doesn't even see my WiFi - even right next to it in the same room!
I connect via the ethernet cable fine-- and the other Mac/iPod/PC are accessing WiFi fine. The PBG4 finds the neighbors WiFi - but not mine!
I type in the name and password-- nope, nothing! I turn Airport off and then try the cable and perfect-- I'm on the www but not with "WiFi".
This seems very strange-- usually it's all or none-- sometimes a PC can kick-off the other computers and I have to pull the electrical (is that a hard restart to the modems etc?)
But this is really a bit strange...
Thanks for any suggestions on what to do here.
Best regards,

Hello -- Good questions but I'll need help in order to answer them.
I have a D-Link WiFi Modem - DIR-635- Dec 2007 purchase, and here's some info from the 90 page manual:
Combines award winning router features and Draft 802.11n wireless technology to provide the best wireless performance.
Compatible with 802.11b and 802.11g Devices - The DIR-635 is still fully compatible with the IEEE
802.11b standard, so it can connect with existing 802.11b PCI, USB and Cardbus adapters.
Would a Dec 2007 iPod Touch 1st Gen be on WiFi 'n'? How to check?
How to find the channel on which the WiFi is broadcasting?
Thanks for any replies and then I can re-reply!
The crazy thing is that I'm almost certain I've had my PBG4 connected to the web via this (my first and only) D-Link WiFi DIR-635 Modem.
