Leopard upgrade = no wireless networking

I upgraded my Mac Mini (1.83 GHz Core 2 Duo) to Leopard the other day. Took it to 10.5.2 right after the upgrade.
Everything worked flawlessly for about 2 days.
Then the AirPort networking started dropping it's connection. I have a Wireless Router setup right beside the Mini which it now just barely picks up (1-2 bars) and drops the connection every few hours.
And I can no longer browse / see any of the other wireless networks in my neighborhood.
My MacBook which I also upgraded to Leopard is working fine. Full signal strength and can see the 5-10 other networks in my vicinity.
The Mac Mini was also working perfectly fine before I upgraded to Leopard.
I tried deleting the com.apple.airport.preferences.plist as some posts suggest but that doesn't work. I also did a SAFE mode boot to no avail. There seems to be other Mini owners with similar problems but no solutions.
I don't want to revert to 10.4 ... any suggestions?

I'M HAVING THE SAME ISSUE ON AN OLDER POWERBOOK G4 (TITANIUM). I CALLED APPLE SUPPORT AND THEY TRIED SEVERAL CHANGES TO AIRPORT SETTINGS (SUCH AS CHANNEL CHANGES). NO SUCCESS. THEIR LAST WORDS TO ME WERE...WELL, LEOPARD REALLY WASN'T BUILT TO RUN ON OLDER MODEL LAPTOPS. THIS, OF COURSE, IS A CROCK OF S__T AS THE LAPTOP MEETS ALL TECHNICAL SPEC REQUIREMENTS FOR LEOPARD
WHAT'S UP APPLE? SHAME ON YOU FOR NOT ADDRESSING THIS ISSUE. IT'S ALL OVER YOUR DISCUSSION BOARDS BUT YOU REMAIN SILENT. IT'S DISGUSTINGLY ARROGANT.

Leopard not recognising wireless networks

So I clean installed Leopard on an external HD, but network preferences wont recognise my wireless network or any of the other five I can usually see from here. However, when I am presented with Network Diagnostics option I can see all the wireless networks I would expect, and am able to log into mine. Problem is if the computer sleeps, or if I tinker with the Network Preferences, the connection drops again. Anyone having this problem?

I've also been having this problem since installing Leopard. Every once in a while, my connection will drop (the greyed-out AirPort signal will appear) and Adium will reconnect. This happens sometimes four or fives times in a row. I found that rebooting the airport card via the menu bar fixes it temporarily but it returns.
I also cannot see the other networks in my neighborhood from the menu bar, but can from the Diagnostics. Mine comes up in the networks menu but I have the feeling if I did a fresh install of Leopard, I would have the same problems as the previous posters. Since this is a fairly bad bug in Leopard, I'm sure Apple will come out with a fix for it. It is a new release, afterall. I trust Apple with their updates.

Upgrading Mixed Wireless Network

I'm considering the new Airport Extreme from Apple, as I may want to get the Apple TV later on. Here's my current equipment:
1. iMac G5 (pre Intel, pre iSight) connected via Cat5 to an old Linksys Wireless B router.
2. Apple Mac Mini (pre Intel) w/ built in wireless (G, I think)
3. Windows XP Home computer with Linksys Wireless G USB adaptor.
From what I've read, if I replace the Linksys router with the new Airport Extreme router, the entire system will operate no faster than "G" speeds, as any "G" device detected will slow the entire system down.
I could get a Linksys Wireless Draft-N USB adaptor for my Windows computer, but I can see no way of upgrading the Mini's wireless speed. Apple doesn't make an "N" USB adaptor, so I don't think there's an Apple solution for the Mini. And I don't think the Linksys adaptor will work with the Mini either, as I don't think their software drivers are available in Mac format.
Am I stuck in "G" mode until I replace my Mac Mini, or is there a suggestion someone could provide?
Thanks.

<< the entire system will operate no faster than "G" speeds, as any "G" device detected will slow the entire system down.>>
Not quite. Clearly you won't expect a g device to work any faster than a g device, but an n device will work nearly as fast as an n device on an n only network (130 mbits/s compared to 144 mbits/s). So any connection between your G5 and an TV would be more or less at n speed.
The mac mini will only connect at g, but g is more than fast enough for HD content streaming to an TV

Snow Leopard upgrade broke bridged networking through hardware VPN in a VM

I have been using an Ubuntu VM through Parallels to connect into work through a Cisco hardware VPN box. When I upgraded to Snow Leopard this past Sunday I noticed that bridged networking no longer worked. I reproduced this problem using VirtualBox so this isn't a Parallels problem. I can connect fine with bridged networking and no hardware VPN box. I can also connect fine through the hardware VPN if I use shared networking. Sadly I need bridged networking for various tools I use. Is this a known issue?
thanks much
Rick

After power cycling the VPN box and rebooting Snow Leopard a couple of times things seemed to have sorted themselves out. Chaulk it up to a stray alpha particle...

Snow Leopard upgrade & printing wireless with Epson px800fw

Hi there,
after upgrading to 10.6.1 I'm not able to print anything to my Epson px800fw. It is connected wireless - funny thing is that scans do work properly while I can't print out anything.
Tried to install the latest drivers from the Epson site but still no success.
The printer manager always shows an error and wants me to install new software (but does not say what to update).
Any ideas?
Thanks for any input
Dietmar

I finally got it managed.
Found different solutions in this forum and what worked was to remove the printer from the printer settings and add a new printer. The system immediately found my Epson printer and installed the correct drivers so everything is working again.
Sorry for any inconveniences

Hi. I have Pavillion P7-1037c that i would like to upgrade the wireless network card on. The board on it has 3 pci-express X1 and a pci-express minicard slots avaiable. I need a card that is dual band compatible. I know there is a minicard 2.4GHtz installed. Has anyone been sucessful at this kind of upgrade? This would be my first minicard upgrade, so i thought I should ask. TY
This question was solved.

Which OS is installed in your desktop PC?
What are the capabilities of your wireless router? 802.11 A\B\G\N\AC ? 2.4GHz \ 5 GHz or both simultaneously?
My own preference is the current 802.11AC standard.
I use Windows 8.1 \ Windows 7 \ Linux on this desktop PC. I have a Sitecom 802.11AC router and an ASUS USB-AC56 wireless adapter. The throughput for video streaaming I am getting from the setup is around 533 mb/second. There isn't much currently available on the makrket in terms of reliable PCI express x1 wireless cards for Windows 8 or 8.1.

Can't Connect OfficeJet 7410 to new wireless network - used to work on old one

Hi, I'm on a Mac OS. I just upgraded my wireless network to use an airport extreme. I have a verizon fios router - same as I had when it used to connect. The only change was adding the airport extreme. Now, the officejet 7410 all-in-one will not connect to the wireless connect. It SEES the name of the network, and asks me for a WEP Key, which it didn't used to do. It used to ask me for the network password. I found the WEP key on the router and it acts like it is trying to connect but takes a long time and then gives me an error. One time it never gave me an error and seemed like it had worked, but was not connected. It just gave up.
My configuration page indicates offline with no active connection and wireless status disconnected.
I restarted everything with no change. I don't know why it would be asking me for a WEP key this time and then not accept it but that was the first indication that something was different when it didn't ask me for the network password.
Also, as a separate issue but related. In trying to fix this, I deleted my drivers to reinstall and see if I started over that it would work. That created another problem in that now it seems that HP no longer supports a driver for this printer. Is that even possible? It's not that old. It says it does not exist on the software update. Please help!

Hi YSJA,
I'm sorry to hear you've had problems accessing your Officejet 7410 since adding the AirPort Extreme to your home network.
I have included a link to HP's Wireless Printing Center troubleshooting section. It has section, "Was anything changed or updated on your router recently?" that has detailed steps to help you resolve the issue.

HP LaserJet Pro 100 color MFP M175nw does not connect to wireless network

I recently upgraded my wireless network router. I had my HP LaserJet Pro 100 color MFP M175nw connected to the old wireless network router. The SSID is password protected (WPA2)
I need to connect the printer to the new wireless network router. However, neither the control panel nor blue wireless connection button provide any way for me to do this. The manual has not walked through a way to do this.
There really needs to be a simple, no-nonsense way to just connect the printer to the wireless network. How do I connect this printer to a new wireless network?

Hi @shakayumi ,
I see that you are having issues configuring the printer on the new router. I would like to help.
Restore the printer's network defaults.
Touch the Setup button. (wrench)
Select Network Setup Menu.
Then select Restore Defaults.
Print out a configuration report to make sure the IP address is 0.0.0.0 and the SSID is cleared.
Printing a Configuration Report.
Here are the directions for setting up the printer through the Wireless Direct to configure the printer over the network as Infrastructure.
Turn the Wireless Direct on the printer.
On the printer touch the setup button, (wrench) then select network setup menu, select wireless menu, select wireless direct and turn it on.
On the computer, in the bottom right corner click on the wireless icon and select the printer from the list to connect to. Then open Internet Explorer and type in the IP address (192.168.223.1) for the printer in the address bar.
This will load the embedded web server for the printer.
Select the networking tab, wireless on the left hand side.
Fill out all your network information, select infrastructure, select your network name, put in password and type of encryption. Apply settings.
Click on the wireless icon and connect back to your network name.
Print out a configuration report to make sure the IP address is valid. (192... or 10....)
Now create a new port, this will save you the time, instead of uninstalling and reinstalling the software.
Go to Start, Devices and Printers, right click the printer, go to Printer Properties, select the Ports tab.
Click Add Port, select Standard TCP/IP Port, then select New Port and follow the wizard.
Type in the proper IP address for the printer.
Make sure the printer is online.
Test the printer.
If you are still having issues, then try this method:
If you have a Ethernet cable, connect it from the printer to the router.
Wait about a minute, print the configuration page to see if you get a IP address.
Then type the IP address into Internet Explorer's address bar to bring up the printer's web page.
Select the networking tab, wireless on the left hand side.
Fill out all your network information, select infrastructure, select your network name, put in password and type of encryption. Apply settings.
Then disconnect the Ethernet cable.
Then wait a minute to see if you get a wireless light on the printer, print the configuration page and check the IP address again. Then type the IP address into Internet Explorer's address bar to bring up the printer's web page.
If the printer is back on the network, create a new port. Steps are listed above.
Make sure the printer is online.
Try and print now.

Wireless network connectivity issues after upgrading to Snow Leopard

After upgrading to Snow Leopard (10.6.4) I find that my wireless network will not automatically connect to my router (Netgear DG834G) as it used to. First impressions are that the macbook is finding a number of wireless networks but wants to connect to the one that is alphabetically first in the list. It also seems that the signal that the airport is receiving is weak, even when the macbook is next to the router.
Has anyone experienced this when they upgraded?
Any and all help gratefully appreciated
Nick

but a couple that I used with no problem before I upgraded now give me a "server not found" error after I enter my login and password.
Quit Safari. Open Keychain Access /Applications/Utilities. Select Passwords on the left.
Delete the keychains for the sites you have problems logging into AND the Safari Forms Autofill keychain. Now from the menu bar click Keychain Access / Keychain First Aid. Select: Verify. If necessary, select: Repair. You will be prompted for your admin password. Click Start.
Relaunch Safari. Navigate to a site. Login with your user name and password. That will create a new keychain for you.
If you still have problems accessing sites, go to Safari / Preferences then select the Security tab. Click: Show Cookies. Delete all cookies or just the one's for the problematic sites. Now try logging into a site again.
Even though you upgraded to v10.6.7 make sure Safari is up to date. From the menu bar click Safari / About Safari. If it's a version prior to 5.0.5, click your Apple menu (top left in your screen) then click: Software Update...
And check Safari / Preferences - Extensions. Something there may be preventing you from accessing secure sites. If you have any extensions installed, turn that off, quit then relaunch Safari to test.

My husband has a Mac mini, vintage 2009, running Snow Leopard. All other computers and devices in the house are able to connect to our wireless network, but since I upgraded his computer to Snow Leaopard it won't connect. What is the problem?

What am I missing here. I'm sure it is some kind of sitting that is not right.
Thanks Pat

Sounds familiar:

Power off and then back on the router
What happens when you enter the network's PW?
Try forgetting/deleting the network if necessary. To do that go to System Preferences>Network>wifi>Advanced and select the network and click on the minus sign

Network connection extremely slow after snow leopard upgrade

I should first state that my son's new Intel Mac Mini (2009 model) is working fine without any issues - it is on the "n" band. My wife's macbook (on Leopard) and my Thinkpad are continuing to work fine - both connecting to the "g" band of my Simultaneous Dual band AEBS.
On my 2008 model mac mini, the installation went thru fine, but the network connection is extremely slow - it is connecting using the "g" band. Even when I launch the Airport utility, it takes a while to locate the AEBS and then when I click on "Manual Setup", it takes a very very long time to read the configuration. This tells me that the airport interface on the mac mini has some driver issue.
I tried all the suggestions given in other threads (listed below), but none of them worked.
1. Created a new network location and rebooted
2. Trashed the com.apple.airport.airportutility.plist and rebooted
3. Rebooted countless number of times - illogical, but that kicks in when I can't find a solution.
It is past midnight here (20miles from Apple headquarter). Going to wait for another 30minutes. After that, I will use SuperDuper to install my Leopard back on my mac mini which I had cloned before starting the installation.
Appreciate any suggestions - I am open to any prayer solution as well! If not, the Snow Leopard family pack is going back to the Apple store on Monday.
Just saw at engadget: "On a 17-inch unibody we were putting through the paces, the WiFi inexplicably has gone out and we have yet to get it working again."

Some more info about my setup:
*Simultaneous Dual band AEBS:*
Radio Mode: 802.11n only (5 GHz) - 802.11b/g
Radio Channel Selection: Manual - 161 (5GHz), 6(2.4GHz)
*Airport Express:*
Wireless mode: Extend a wireless network
Allow wireless clients checked under the name of the network (same as for AEBS).
Both are WPA/WPA2 Personal security. And both the routers were upgraded to 7.4.2 firmware this morning with the hope that it will help.
*N Devices (both working fine):*
Apple TV 40GB
2009 Model Mac Mini upgraded to Snow Leopard - working perfectly.
*G Devices:*
Thinkpad running WinXP
Dell Laptop running WinXP
Acer Netbook running WinXP
iPod Touch
iPhone 3G
Linksys webcam
_All of the above are working fine_.
+2008 model Mac mini -+ upgrade to Snow Leopard shows extremely slow wifi connection that it is unusable. It takes 20min to load apple homepage. When I boot from the clone of my Leopard lying on my external drive, it works perfectly.
I compared the settings between all the tabs of Network-->Airport-->Advanced and they are identical between Snow Leopard and Leopard mode except that SL doesn't have the "Apple Talk" tab.
Appreciate any help to debug this.

Upgraded 4s to iOS8 and can't connect to certain wireless networks anymore

I have an iPhone 4s that I updated to iOS 8. Prior to update, I was using iOS 7 (whatever the latest iteration was), and was able to connect to various wireless networks. Following the update, I am no longer able to connect to the wireless network at my place of work. It tries to connect, does so briefly, and give me an authentication request (screenshot attached). Blank username/passwords don't work, neither does the network name/password combo. Choosing cancel will revert the connection back to 3G.
To try and fix the problem, I have "forgotten" the connection, re-started the phone, and neither has worked I have reset my network connections, and it worked immediately after the reset. The phone was inactive for a while, and upon unlocking, it had reverted to 3G. When I tried to re-connect, it gave the same errors already stated.
I no longer have a back-up from before the upgrade, so I can't go back to 7. My wireless connection on my home network is fine. Nothing has changed with the work wireless since it was working with my iOS 7. It uses a WPA-Personal security, and there are several repeaters for the signal throughout the building.
What is going on and how can I fix it?

MacBook can't see my home wireless network after upgrade to OSX 10.8.5

After upgrading to OSX 10.8.5, my MacBook does not detect any wireless nertworks. My iPad and iPhone work fine, my router has been rebooted, WiFi is turned on, and the ethernet connection is how I am writing this message to you via broadband. There are a half dozen wireless networks in range (according to my iPhone) but the MacBook cannot find the router I am sitting next to. Any ideas on how to correct this issue?

It appears an SMC reset was required:

Here is your other post: MacBook can't see my home wireless network after upgrade to OSX 10.8.5
If you reply to it and marked it "solved", perhaps with a link to that post (copy and paste it, or just say you performed the SMC reset) it will help others find a solution. Thanks!
