OS X v10.4 Tiger Upgrade problem - lost wireless connection

I upgraded my IMAC OS X 10.3.9 Panther to OS X 10.4 Tiger. I used the setup step "Upgrade Mac OS X", everything appears to have updated but I lost my internet and email connect-ability. I talked with my ISP they couldn't help and Apple said its beyond warranty. Should I have used the setup step "Archive and Install" instead? I just wanted to upgrade my OS and keep everything else the same. If I need to - is there a way to uninstall Tiger and restore my old Panther?

mikech:

The upgrade option should have preserved everything and only upgraded the OS and native apps. There is no Previous Systems Folder with an upgrade install.
Can you explain what you mean by losing internet and email connectivity? You are not able to connect to the internet, is that so? And you are therefore not able to access email? Are you using Apple Mail or some other mail client?
Clarifying the issues will better help us in making suggestions.

Im having the same problem. My Netgear used to connect wirlessly to the network and the inernet, now all it connects to is the network. And comes back with an error saying not connected to the internet.
The only way I can use the internet now is through the Ethernet connection out of the Netgear.

Satellite L500 - Lost wireless connection

My Satellite L500 recently lost wireless connection. I looked up the Realtek wireless device in Device Manager, and it says the device is working properly. I have tried using "ping 192.168.1.1" to reach the router, and I get "Transmit error - general failure".
Any ideas?

Hi buddy,
And now does Windows recognize some WLAN networks in range? Your posting lost wireless connection is not very useful
You should try a WLAN driver update that you can download on official Toshiba page:
http://aps2.toshiba-tro.de/wlan/
If you still cannot find or connect to WLAN networks disable the WLAN power saving mode in Windows power profiles. You have to set it to maximum performance.

E60 lost wireless connection to network

my E60 lost wireless connection to network. tried GPS, DUAL, automatic, manual search for network. Same SIM works fine with different phone. Any idea anyone?

Hi Neil
I'm not familiar with HH (I use a third party router) but it looks as though the HH is set to NOT broadcast the SSID. I'm sure that if you go into the HH settings (the address foe the HH should be 192.168.1.254) you should find somewhere a check box or whatever that allows the router to b'cast the SSID or not. Some would argue that you should not b'cast the SSID but IMHO it makes no difference as the SSID is so easy to discover even if it's not being b'cast.
Just another thought is that you might have to set the wireless connection up as a separate connection to the wired connection. I don't know which OS you are using but if Win 7 then go into 'Network and Sharing centre' and then select 'connect to a network' and take it from there. If not on Win 7 then, if I recall correctly, right click on the networking icon in the system tray and there should be an option to connect to a network.
Hope this helps, if not then I'm sure there are other HH users on this forum who will provide advice.

Not the average problem with wireless connection. Please help me..

I've been having wireless connection problems ever since I upgraded to Verizon FiOS from Verizon Wireless. Before upgrading to Verizon FiOS in the fall of 2012, my brother's laptop connected just fine with the connection. After upgrading to Verizon FiOS, my brother's laptop could not connect to the internet. It showed the wireless connection signal as Excellent, but I could not access the internet. Either it would be extremely slow or there would be no connection at all. Also, the router would sometimes restart itself randomly, and it was extremely annoying for me since I am hardwired with my desktop.
This was weird because my iPod Touch connected perfectly fine to the wifi. So I thought it must be the laptop. But I brought the laptop over to my cousin's house, who also happens to have Verizon FiOS, and the laptop connected perfectly fine. I called Verizon and none of the technicians knew what the problem was. We tried disabling and enabling the router, changing the channels, and anything that was on the list. They couldn't help me and I was extremely disappointed because not only am I not accessing the internet with my brother's laptop, but I am also paying for the service too. The last technician I called in 2012 decided to send me a new router. I hoped this would work, but it did not. This router, too, would completely reset itself numerous times before settling down and letting me use the internet.
I gave up after that. But in the spring of 2013, I got really fed up with the service I was receiving and I decided to call Verizon again. Again, Verizon tried to help me fix the laptop with their tools and solution guides. But nothing good came out of it, so I decided to ask for a technician to come to my apartment to fix it. We scheduled a day and I was pretty excited since I was almost positive that the connection for the laptop would be fine by then.
I was wrong. The technician came and only stayed for about 20 minutes. He said it must be the laptop or it must be that the walls are too thick in my apartment. But that can't be it since, in my cousin's house, the router is on the second floor and my brother was using his laptop on the first floor. So it couldn't be the laptop nor the house. So we came to no conclusion. He just attached a mini router to the laptop and hardwired it. I wasn't so content but I was glad my brother could finally use the internet now.
About three months pass by and I decide to get myself a new laptop. I get it and I am hoping the wireless connection works. It did, so I was almost positive that it was my brother's laptop that was the problem, not the wireless signal. I go on vacation for a few days and I connect perfectly fine at my friend's house. When I return home and try to connect to my wireless connection, it didn't work!
At this point, I am extremely frustrated. I decided to call Verizon again to replace my router because it was being extremely annoying. It kept resetting itself and I was tired of it. I replaced the router, and this is the router I currently have, but I STILL have the same problem. It resets itself on its own time and I hate it because I'm always in the middle of something. Wow, just wow. There is nothing they could do to help me fix this. I call up a technician, for the millionth time, and he tells me he can't access my router. This occurred with the previous technician who sent me the new router. He tells me his tools are not working and tells me he'll call me back the next day.
It was the next day and I did not receive any phone call. I am extremely disappointed in Verizon FiOS' service and it's customer service. I leave it alone and I just hardwire my laptop to the router. Of course this works, but what's the point of having a laptop when I have to keep it hardwired on my desk? After a day or two, I decide to check if the wireless connection works, and it did. I was surprised. But every now and then, it would shift on and off. Most of the time, the wireless connection is either EXREMELY SLOW or I get none at all, nonetheless, it still says the connection is Excellent.
Please, if there is anyone who could help or try to help me, I would most appreciate it. If there is more information that you need, ask me and I will try my best to provide it to you.

Admittedly, that IS a strange case. Unfortunately, it sounds like all possible troubleshooting has been done by the tech support agents. you mentioned that you were dissatisfied with your other service, did it have a similar problem? theres a possibility of dirty fiber or a bad ONT port, but the random rebooting of the router would almost exclusively be a bad router. question: is the router in the same location as before?

Lost wireless connection with mx860

i lost my wireless connection with my mx860 - please help, i have tried it all
thank you

Did you solve your printer connection problem? I have the same issue. When I first turn the system on, it is connected. But after a short time (a few minutes?) it loses connection between Mac and printer, even tho both are connected to my WIFI. I have to turn the printer and and off to reconnect it to the Mac. Very frustrating. I have checked Netgear, Printer and Mac settings and can't find any explanation.

Lost Wireless Connection Again

Out of the blue in the middle of loading a web site, I lost wirless connection and nothing would make it reconnect. (turning ariport card off and on, sleep, diagnostics, etc) Connetion status went grey as well.
However, I was able to plug an eithernet cable in and when launching Safari, it brought up diagostics again but connected via ethernet. After about a minute of use, I unplugged the ethernet and I remained on. When connected via ethernet, the airport strength indicator went back again - that is why I unplugged the ethernet cable.
Important to note that I did NOT reboot the router.
Odd for sure.

Having problem with wireless connection

Hello Everyone,
Ok, just like what the title says.. I had a roomate before that had the acct. and moved out with his account. I used to share Internet service with him using a WRT54G router and everything was fine. Since he moved out I had to get my own one on my name and started using the same router, but this time I decided to put a security on it, I lost my CD, so I decided to go to linksysfix and download the program. I installed it on my lap top and everything is working good, except for the desk top that my brother has. His also connected to the router that I have but cannot connect on the wireless, the desk top used to work before I downloaded from linksysfix. We can see the network name and the signal is high but won't connect and cannot go online. It's kinda weird, wireless used to work before the reset and installing from linksysfix. My lap top is working great, no problem with it, just the desk top. Desk top works using wire, but the wireless function is not working. Called tech support for linksys and dynex for wireless card and did not do the job. Last night I was trying still and was able to connect wireless on some network called STREAM, not sure where it is, but they're homepage shows up. anyway, any help would be greatly appreciated.. Thanks
Ricky

Go to: Start Menu>>Control Panel>>Network and Internet Connections>>Network Connections. In this window look for your wireless connection icon and right click on it, then click on properties. Here you will find the wireless tab to set up your wireless card.
1.security = either WPA or WPA2
2.Encryption = TKIP or AES
3Security Key = whatever you decide to choose =Wwd3Rtt29PlsM =example
***Also you should plug in you wireless computer with the wired Ethernet cable while you are doing this, then dissconnect.
Good Luck,

Equium A110 - Lost wireless connection

Hello all,
can you help?
I have lost connection on my Equium A110 and also another laptop (not Toshiba) it askes for or incorrect IP address.
I have an linksys router which has had its filmware up to date

Hello
For me its definitively not a notebook issue because on the other notebook you have a problem with the wireless connection too.
Its not so easy to say what the reason is for this
In your case I would try the command line the command ipconfig /renew
Does it work?
If it doesnt work you should try to disconnect the router from the AC/DC adaptor for at least 5 minutes. Then connect the AC/DC adaptor again and try it.
Good luck!

Lost wireless connection on a wrt110 router!

Oh HELPPPPP! I lost my wireless connection last week, it just vanished! Called Dell they couldn't figure it out, I worked on it I can't figure it out. It was there then it was just gone!! All drivers are updated, but I keep getting the error message " the network adapter intel(r) wifi link 4965agn is experiencing driver or hardware related issues" ... This is driving me nuts, any suggestions???

Well, this problem is not related with your Linksys router. It is driver error on your computer. I would suggest you check the Device Manager in WIndows to see if your wireless adapter in your computer was installed properly. If it shows a yellow triangle in the device manager you have to reinstall the driver.

Lost wireless connection with Lexmark Printer

MBPro with 10.8.1. Lost my wireless connection with X6675 Lexmark printer. How do I reestablish the connection. My router is a Time Machine.

10.5.2, Mac Pro with AE Card, AEBS (not Gigabit) lost wireless connection

Since I upgraded to 10.5.2, I have been having issues with my wireless connection on my Mac Pro. Here's my setup - an 802.11n Airport Extreme Base Station (not gigabit one) with a 802.11g AEBS connected to it. the 802.11n is running on the 5GHz Spectrum only and does not share with 802.11a (so it's running 802.11n only). The 802.11g AEBS is set to run on the 2.4GHz Spectrum and is set to accept both 802.11g and 802.11b. The MacPro has an Airport Extreme Card running 802.11n. The 802.11n base station is almost next to the 2 base stations.
Every once in a while, my Mac Pro will get disconnect to the basestation, and when I go to the Airport Signal icon, I can see both my basestation. I just have to select it again as if all of a sudden, my Mac Pro forgot which basestation it is connected to and get totally confused. It is one thing if the signal to the basestation is gone (have experienced that a few times when I have the 802.11g base station), it's something else to just get disconnected for no reason. Of course, when I select my basestation again, everything works fine (not as if it has problem re-establishing connection). This is getting a bit annoying, especially when I am trying to backup my files only to have been disconnected from the basestation. This doesn't happen every time I backup my files. It happens in random and there can be a long time without having drop the connection and then it can drop the connection 3 times in 10 minutes.
Help!

I have read all the other post, but got no satisfying answer other than people saying Apple really screwed up with 10.5.2 and that doesn't really resolve the problem. Plus, it seems to me that most people's problem are with a 3rd party base station rather than an AEBS. My only other option maybe to down grade my Airport Card software, because I think the problem is with the Airport Card driver that's bundled with the Mac Pro, and frankly, I am not sure if Apple is ignoring the problem or working hard on it, but in either case, it's not fast enough in term of damage control.

Having a problem with wireless connection. On my Windows XP 32 bit system and a 6510 printer, initi

On my Dell Latitude D620, Windows XP 32 bit system and my 6510 printer wireless connection (Linksys EA4500) , everything works fine after the computer is booted. After a period of time (usually overnight), I lose connection to the printer (the scanner icon with a red x is shown on my Windows task bar and I can't print. Ran Windows Fix and the HP fix programs. The only thing that solves it is to reboot the computer. A second symptom is that my IE8 stops connecting to the internet at the same time (gives a 'waiting for' response that never changes). Firefox still connects OK when this is happening. So I suspect the problem isn't with the printer, but with my Windows set up. It is a fresh XP SP3 install (hard drive crashed, but it happened before also). I reset IE, checked my proxy, no malware, happens with or without firewalls and security programs.
Hoping that someone else has run into this problem. Been all over Google, and the IE doesn't work / Firefox works is fairly common, but none of the fixes helps.

If you want you can reload Firefox 4.0 or the last "old" version is 3.6.16 and is available here:
http://www.mozilla.com/en-US/firefox/all-older.html
Just reinstall your choice of FF. The bookmarks are in a different directory and are NOT overwritten. Some of the Add-ons that worked in 3.6 DO NOT work with 4.0, pay attention and head any warnings when you start 4.0.
I had to disable extensions: Flashblock and WOT
Firefox SafeMode? - A troubleshooting mode.
1.You can open the Firefox 4.0 SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut to open it again.
