MacBook, 10.4.8, and wireless network problems. How I solved it.

Hi
I've seen a few post about not connecting to a wireless network after the 10.4.8 upgrade.
Before the 10.4.8 update my MacBook worked fine on my wireless network; after the 10.4.8 update I could not connect to my network via AirPort, though it kept offering to connect to my neighbours networks. My wireless network is configured for WPA.
I managed to get this working by deleting my existing AirPort network configuration from System Preferences and creating a new configuration with the same network settings.
Hope this helps,
Matt
iMac G5 1.8GHz 1GB 20"; MacBook 1GB; Mac OS X (10.4.8)

In "Network" I deleted all prefered networks one by one, set it to automatic, turned airport off and back on, and add my network again as prefered network, set it back to connect to preferred network. see apples instructions:
http://docs.info.apple.com/article.html?artnum=304482
Now its fast and connects by it self again.

Dreamweaver and wireless network problem

This isn't about Airport, but I couldn't find the proper place to post this, so I put it here. Please advise if I'm wrong.
I'm running Tiger (10.4.2) on a dual G5. My husband is running Windows XP on a 2GHz Dell, and also a Dell laptop. We just moved and HE is wireless now, not me. I am hardwired to a Netgear router (doesn't seem to have a name but the number on the bottom is CD814WG). We are using RoadRunner as our ISP, as we have done for seven or eight years, since its introduction into our city. TimeWarner did our installation, and everything is fine with my machine (although my husband's problems are another issue altogether!).
I should also say that we are in no way networked, and that is not our goal or plan. We have the Netgear router, and as I mentioned, I'm wired directly to it. We both use broadband individually, and have no need to share a connection.
I'm not having any problems at all with my broadband connection -- internet and Mail are fine -- but since the installation of the Netgear router I can't use Dreamweaver to upload HTML pages I create. I can use Fetch just fine, which doesn't surprise me since I've always powered right through my firewall with Fetch, while I always had to turn it off, with Dreamweaver. And of course I should say that my firewall is down when I have the uploading problem. The built-in OS X firewall is currently the only one I have installed, BTW.
When I try to upload, DW gives me a dialog box saying "Dreamweaver cannot determine the remote server time. The Select Newer and Sychronize commands will not be available." And of course I can't upload anything.
Any ideas? I have the information the TimeWarner guy left here so I can go onto the Netgear admin page, but I don't know what to change/add so that I'm able to upload with DW. It's my understanding that port 80 is for internet connections, but as I mentioned, it's not blocked -- I can go online just fine. It's just that I can no longer upload HTML pages with Dreamweaver.
Thanks in advance...

I'm getting the same error message as you (Dreamweaver cannot determine the remote server time...).
I found that I could no longer upload with Dreamweaver (or see all the remote files) but I could with Transmit. However (and here the similarity ends) when I turned off the OSX firewall everything was fine.
This didn't make me feel very easy, however, as I preferred having the firewall up. I found that it would work with the firewall up if I checked the "use passive FTP" box in Remote Info in the Site Definition menu.
The Netgear router also has an NAT Firewall but I am using a Netgear router too, both hardwired on my iMac (via Airport Extreme - don't ask!) and wirelessly on my laptop. I haven't configured the firewall on that at all (I wouldn't dare!) and I'm getting through OK now. Try the passive FTP thing; it might work!

Wired and wireless network problem

I have an Airport Extreme setup with an 20" imac connected thru ethernet. I also have a 17" Macbook Pro connected wireless. Both have no problems connecting to the internet but I want to be able to talk to each other. I checked and the wired network has a different subnet then the wireless one. I would like to have them both on the same subnet but I can't seem to find a setting in my airport extreme that will allow me to change that.. The wired network seems to be the same subnet as the assigned address from my ISP. I only have 1 address from my ISP so the airport is not acting like a switch it is routing the data just creating a internal network based on the ip from the ISP. The wireless is handing out ip address that I have setup in the DHCP section.

Hmmmm
It sounds like you have your AirPort Extreme configured to be in bridge mode? Is this the case?
If it is the case, then you can configure it to "share a single IP address" and then both the wired 20" iMac and the MBP would get DHCP addresses on the same subnet....
If your Airport Extreme is already setup to share a single IP address then the two stations really ought to have IP addresses from the same subnet. Perhaps one of more of them has a static IP and is not setup to use DHCP?

Connecting a macbook pro to a verizon wireless network

how do i connect a macbook pro to a verizon wireless network? Wi-Fi connection automatically assigns an IP address and indicates that the Mac won't be able to connect to the internet. Two other MacBook Pros connect to the network without any problems. These Macs travel from home to school and back again and automatically reconnect when they are brought into the house.

I have read a few corporate IT policies and they are all PC-centric.
Unless your mac runs any windows tools such as Bootcamp Wine, Crossover, or a VM in parallels or VMware then your mac has no virus implications.
A few years ago word documents could be infected with macro viruses and although did not affect a mac a mac could pass them on. Up to date versions of Microsoft Word documents are not vulnerable to this flaw.
You could install ClamAV its a free anti virus app for the mac that would keep your IT dept happy.
Maybe I can find out what the WEP key is with a utility of some kind.
If you had a compatible usb wifi dongle and kismac you could crack their WEP key but this would be probably illegal in your country so I dont condone this activity but if you got written permission from your employer to give them a free penetration test, something that normally involves hiring a security company this would save them money and highlight the insecurity on their network.
Or use an Ethernet connection.

Airport and Wireless network issues

I have read all the issues about airport and wireless network. I don't see the issues that I have. My issue is that my wireless network used to automatically connect as soon as I power up my powerbook; then one day I power up and I was connected to default and I did not see my wireless address listed. I when into airport setup to try and setup again and it would not let me saying my password was not right. I logged off and then on again this time my network address was listed, but it still would not connect automatically to the network, now everytime I go to the web I must pick my own network and put in a passwork that sometimes works and sometimes not.
I have not done any updates or put any new software on the powerbook, so this is not the reason for my problem.
Please Help!!!
Thank's

Had this issue with our imac after upgrading to 10.4
The answer was to go into Network and select airport tab.
Listed there (for me) were three settings. Delete all of them ,they will probably include the actual network you want! Click to apply. Re-start the Mac.
Go back to network and airport and you should now see only the network you wish to join. It will ask for passwords again!!
Click apply and restart. It worked for me.

DHCP Server - Different Range for Wired and Wireless Network

We have DHCP setup on Windows Server 2012r2 and the range given to us by the main HQ is 10.65.112.1-10.65.112.254 (there are several exclusions under this range)
Now since the range gets exhausted quickly, they provided another one 10.65.122.1-10.65.122.254.
What our branch would love to do is to dedicate the first range for Wired Computers and the other range for Wireless Devices (Phone,Tablets, Mobiles)
Right now we have 2 different scopes setup in DHCP, the second one is disabled. In our network we have 6 access points and also have a CISCO SG300-52 Managed Switch. It has an inbuilt DHCP Server and also has the function for DHCP Relay. But we are not actually using any of its functionality as of now.
So my question is how to have 2 separate ranges for wired and wireless network. People have mentioned vlans but I have no clue on how to get that done.
Is there a simpler way avoding V-LANS or if not, would love to get step by step procedure on how to go about this. Any help will be much appreciated
Regards,
Sheldon

Hi Sheldon, please read this post
https://supportforums.cisco.com/thread/2270049
You will need some modifications though. Steps 1-6 is very relevant. On step 6, you need to pay particular close attention to the "default router". If the SX300 handles your intervlan routing then the default router needs to be the IP of your VLAN. If you have a different device to handle VLAN routing then the default router needs to be that IP address.

Officejet Pro L7780 Wired and wireless networking at same time

I have an officejet pro L7780 printer that I would like to use wired and wireless networking at the same time. It that possible. The printer is connected directly to the network by ethernet, but I would like to print wirelessly with an ipad or iphone using HP ePrint Home and Biz.
Thanks,
Maurice Hawley

The bad news: no it is not possible to have two connections active on your printer at once.
The good news: the router will connect any device to the printer regardless of how the printer or the devices are connected. So your iPad can print to a printer that is wired (with Ethernet) to your router.
If it does not work, restart your router by pulling its power plug momentarily.

Problem with Skype and Wireless Networks

I have been having a problem with Airport for about 10 months. Long winded explanation follows.
Initially file transfers over wireless networks were extremely slow but this seems to have been that 10.5.2 update problem. There is a remaining issue when I use Skype on my Mac (details below) connected to a wireless network the incoming and outgoing audio drop out for 1 - 3 seconds at irregular but frequent intervals (approx every 5 - 10 seconds). This is regardless of the wireless network I am on - and that is dozens of them all over the world. Note it is voice only calls, not video. Apple has replaced the Airport card and the mother board; the OS has been reinstalled; test accounts set up but nothing fixes the problem.
At one point I had temporary relief by switching off 'Configure IPv6' in System Preferences/Network/Airport/TCP/IP. This worked for a month or so but now the problem is back as before.
All other aspects of wireless activity are fine. Wireless firmware is 1.4.4.
I have worn out my welcome with the usually sensational help desk. Any suggestions out there in Mac Land?

Hi there
Been a hectic week here getting this problem resolved. It is all OK now. Here is what we found and how it was done.
When Airport was playing up we set up an unlimited ping of the wireless router in the office. This is what it showed:

and so on.
After discussion with tech support they said the Airpot card had to be replaced. This was done with admirable expediency and I got the MBP back in 36 hours. On testing it the same problem was still there. Identical pattern on the ping test, the fault was not the hardware.
Once more a call to Apple and another tech. This time we booted from the OS 10.5 install disk and ran the ping test. I ran it for a few hours without seeing the fault, it worked fine. The problem had to be in the operating system.
After backing up all the data I zeroed the drive and did a clean install of the OS. Bingo! Problem gone.
So after 10 months, two airport cards and a mother board, the issue was in fact something corrupt deep in the OS.
So to anyone having similar problems with Airport, run a ping test as described above. If you see that kind of pattern, try a clean install before going down the hardware road.

Problems with Installing iTunes and wireless network connection

Every time I attempt to install iTunes it completely kicks the internet off and an error comes up that the wireless network adapter to not connect or is not detected. My internet service is connected to a router which I receive wirelessly to my laptop. I do not understand why it is happening and to get the internet to work again I needed to do a system restore. Any ideas why this is happening. Also when iTunes was installed it came up correctly, it would just not connect to the net. I have had a previous version on my old laptop but since purchasing this new laptop I am having such difficulty. On another note, if this problem can be resolved, once iTunes is working is there a way to get the songs from my old computer onto the new? Thanks for the help in advance!

I just saw your post and I resolved this on mine for my wired connection. I'm willing to bet that the issue is the same for wireless. Here's what I found.
Issue:
During the installation, iTunes installs some network components related to mobile device support over ethernet(Apple Mobile Device Ethernet Service - netaapl.inf). At the same time, according the logs, the install process removed OEM18.inf. This almost exactly coincided with the time that I saw the network connection die (preceded it by a few seconds).
Basically, iTunes appears to be removing a required network component.
Resolution:
After installing iTunes and the network connection breaking, remove the network device from Device Manager and allow Windows to reinstall it automatically.
The following instructions are for Windows 7, but they are close enough to follow for other versions of Windows.
1. Click the Start button (Jewel in Vista and Win7).
2. Right-click Computer and click Manage in the menu that appears (type your password or click Yes if prompted).
3. On the left side of hte Computer Management window, click Device Manager.
4. Click the arrow (or plus sign) next to Network Adapters to expand that section.
5. Right-click your network adapter and click Uninstall in the menu that appears.
6. Click OK.
7. Reboot.
Windows should automatically detect and reinstall your network device on boot.

WiFi and other networking problems (MacBook Air)

Like many others on these forums, I’m having terrible problems with network connections on my MacBook Air 11-inch (Mid 2011, running Lion 10.7.3).
WiFi connections are very unreliable, and often impossible to establish.
On my home network I can ‘force’ the MBAir to connect by manually configuring TCP/IP, and DNS settings. I shouldn’t have to do this.
I do not have (and have never had) problems establishing WiFi connections on all the other Macs that are used on our home network (iMac, and MacBook running SnowLeopard, and an old PowerMac that runs Tiger; I also occasionally use my University MacBookPro (10.6.7) without any problems. So this issue is clearly not network related.
If I take the MBAir out on the road (which is why I bought it) then I invariably struggle and usually fail to establish a WiFi connection, even in my University, where the WiFi network functions with my MacBookPro.
My problems with the MBAir are not however confined to WiFi.
Networking with an Ethernet-USB link is equally unreliable. Occasionally the MBAir appears on network but then fails to connect to any servers. Even when it does appear to connect the network, I’m unable to connect/share the MBAir from any other of my Macs. Ethernet cable and network communications are all trouble-free with my University iMac and MacBookPro.
I’m really disappointed with my MacBook Air what’s going on Apple?!
I’ve tried deleting the usual system preference files (com.apple.airport.- , -.network, etc.) but not much has changed. Now at a loss at what to try next .... advice welcomed.

Whatever was causing my endless problems has been resolved. I was very close to returning my new MacBookAir, as nothing would work with respect to networking; WiFi or Ethernet-USB.
As a last resort I reinstalled Lion using the cmd-R - and yipee all networking problems have disappeared.
The MBAir now works just fine, I can chop and change WiFi connections when roaming without problems, and my ethernet-USB connection allows me to interact with my University network.
My solution - reinstall Lion!

Brand new macbook pro cannot connect to wireless networks

The first time I called apple tech, they thought it was a problem with my internet provider. I've called 4 times now, and I'm still getting the runaround.
I have an old (2001) G4 sitting right next to my macbook pro which can see numerous wireless networks and connect to them all. A strong connection at that. However, my brand new (refurbished) Macbook Pro Intel etc,.... supposedly best computer ever made, . . . . can see the same wireless networks but has never been able to connect. As a student, I saved for a year to buy this notebook so I could work at cafe's & study with my friends. My friends with PC's can all connect to these wireless networks. My friends with older, less expensive notebooks can connect no problem. I have never been able to connect. Bought this peice of junk 2 1/2 months ago - only because I didn't want to be stuck at home anymore with my desktop. Stupid me to trust apple.
I wish I could get my $ back, but I'm now being told that it's 30 days too late. Before they told me it was a minor thing and some software update could fix it. I did as told. downloaded and installed their 10.4.8 thingy - deleted all the keychain stuff - nothing. same peice of junk.
Now they are telling me to go back to the genius bar where folks are just rude to me and tell me they can't help me becuase I bought a "refurbished" model that didn't even save me $25. What do you know.
Anyone having problems like this? Anyone out there who can help me?

Okay,
I apologie for calling it a peice of junk. I know you all probably worship this machine. I'm just really frustrated. I noticed that this is a very common problem - though most of the posts identical to mine have dissapeared from apple.com - this well known defect is all over other discussion boards and websites like macdefect, etc,....
So, can any of you tech gods help me with this very well known, common problem that I haven't been able to fix with 10.4.8 upgrade?
Thanks for your time and assistance,

Macbook Pro can't see wireless network or connect to it, but iPhone can!?!?

ok here"s the deal:
I got my macbook pro in the states through school and it has been working fine ever since. I now just moved back home to Germany and for some odd reason the wireless network at home at my mom's won't appear in my "join network" list.
I have tried diagnostics and advanced stuff, I have even typed in the network name and password into my preferred networks list manually... still nothing. When I connect the computer through an ethernet cable it works just fine. also searched and updated all my updates in case that was maybe the issue...
here's the clue. my sister and her friend both also have macbooks (not pro's though) and both also run leopard and both of their laptops can see and connect to our wireless just fine. ALSO I have an iPhone, I purchased in the states and it can see and connect without any issues as well..
I have called the German Apple support people, but they are absolutely useless and there are exactly 2 (!!!) genius bars here in Germany. one 4h and one 6h from where I live... sighs
this is what I found in my about section, in case anybody knows what this means:
+AirPort Card Information:+
+Wireless Card Type: AirPort Extreme (0x14E4, 0x8C)+
+Wireless Card Locale: USA+
+Wireless Card Firmware Version: Broadcom BCM43xx 1.0 (5.10.91.21)+
is it because it says "USA" and I am now in Germany? but how stupid would that be? other people that bring their American macs over don't have issues either... right???
so yeah... HELP??? ANYBODY??? PLEASE???

Hello,
I had the same problem when I was traveling with my 2009 Macbook Pro. I am on a French ship and my MacBook was bought in the US. We have a wireless gaming network to play Call of Duty on that is set up on a LinkSys router. I was so frustrated because everyone else here could connect and play without a problem. My iPhone would even connect to the network but my MacBook Airport card wouldn't even recognize the network.
It turns out that some countries use different Wifi channels. The Airport card in the US MacBook Pro is setup to only recognize channels 1-11. The European LinkSys router was broadcasting on channel 13 which is why my MacBook couldn't even see it. I changed the wireless channel on the router to 10 and now everything works great. I hope this works for you.
Cheers
P.S. - The US MBP can only recognize channels 1-11 on a standard 2.4GHz network. To see what channels your Airport Card will recognize, open System Profiler (located in the Utilities folder) and find the "Network" heading in the column on the left. Click "Airport" and it should display all of the supported channels in the info box to the right.
