Can't connect to company network anymore.

Hi guys I need help getting online with company network. I use to be able to connect to the internet through ethernet but all of a sudden it will not connect at my office. I can go over to the main office and it will still connect. The other office computers will connect at my office but not my macbook, it shows self assigned ip address and may not connect. I've tried some other things from other post but nothing is working. Please Help, Greg.

This seems to be happening to a lot of people recently. Not sure if this was after the patch or what.
The only way I've been getting around this so far is going to Firewall and setting it to allow all incoming traffic, wait for it to connect and then reset it back to what you had. I would be able to connect most of the day and then would have to do this again the next day.
This is definitely annoying. I'm not sure what's causing this. I hope they get enough complaints to get this fixed.

Can't connect to Wireless Network anymore

Hi
My daughters Mini Mac which is still on 10.4 Tiger (cos we can't get the Snow Leopard DVD to stay in) has stopped connecting to the Wireless network we have in the house, it's been fine up until today, now it just says unable to connect to specified network, is there a way to make the whole thing go back to default settings and start again? Any other suggestions gratefully received.
Thanks

If BD's suggestion does not work............
In the Library/Preferences/SystemConfiguration/ folder delete the following:
com.apple.airport.preferences.plist
NetworkInterfaces.plist
preferences.plist
com.apple.nat.plist
You will have to re-configure all your network settings since deleting"
===============================
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.
If using any of Apple's wireless hardware, run the *Airport Utility app* which is located inside the Utilities folder.

Can't connect to GSM network anymore

Posted in wrong board

Sorry to say, that it's not your local account. If you look at this forum, there are a lot of people having problems with WPA(2) authentication.
I for one have been forced to go from WPA2 Professional to WPA2 Private to get my wireless to work.
There is a lot of hope that 10.5.2 will solve if not all, then some of the issues people have with WPA....

Upgrading to xcode and can't connect to the network

Hi! I use a C++ library in my application which connects to the network (I suppose it uses sockets). I've been using it for months and I was using xcode 3.2.4. Now, I just had the great idea of upgrading to xcode 3.2.5, and I found out my application was crashing with the error:
If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first. 3.2.5
Ok, couldn't solve it, so went back to 3.2.4, as suggested somewhere. The application is not crashing anymore, but now the library can't connect anymore to the network. Tried to rebuild it (I didn't write the library but I have the sources) and use the new library, but nothing. Still the library can't connect to the network. I tried with every simulator.
Any idea what there could be wrong and how I may be able to solve this? Can I somehow delete manually everything related to xcode and the simulator and try to start all over again?
Thanks!

I've been able to temporarily solve this problem by removing the entire Development directory and installing again xcode 3.2.4. Even with xcode 3.2.4 however, the same happened, and I had to do this procedure again. Now it seems to be working correctly, but it seems something very strange has happened. Hasn't anyone experienced anything similar?
Thanks!

Problem in loading images when i am connected on company network

Hi friends, I am using firefox since last 4 months on my windows 8 pro laptop.but since last month I am facing problem in loading images when i am connected on company network but same time it is working fine with ie10. But all these thinks are working well at my home when I am using broadband.

I don't completely understand your issue. Does this issue occur on 1 network and does not occur on another? Have you tried clearing cache and cookies and making sure your plugins are up to date?
Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
Note: ''This will temporarily log you out of all sites you're logged in to.''
To clear cache and cookies do the following:
#Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
#Under "Time range to clear", select "Everything".
#Now, click the arrow next to Details to toggle the Details list active.
#From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
#Now click the ''Clear now'' button.
Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article.
Did this fix your problems? Please report back to us!
Please check if all your plugins are up-to-date. To do this, go to the [http://mozilla.com/plugincheck Mozilla Plugin Check site].
Once you're there, the site will check if all your plugins have the latest versions.
If you see plugins in the list that have a yellow ''Update'' button or a red ''Update now'' button, please update these immediately.
To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

Windows 8, Error: "Can't connect to this network"

I have wracked my brain, my colleague’s brains, and used my googlefu to no avail.
I have a Win8 basic (cheapest OS) HP tablet 1000G2 that I am having troubles with. I have a network that requires WPA2-Enterprise with PEAP. It will not connect to this network, it will however connect to a neighboring network without
any security settings. I have fixed this issue once before and the same fix is not working.
The kicker... I have another exact same tablet that we got the same day... No issues connecting
Problem: It does not take the security settings that the server is prompting for. It prompts me for my credentials, but gives this error: "Can't connect to this network"
I did research last time and the collective reason was that the security settings weren't correct.
Solution that worked last time:
Connect to a network with open sec settings.
Open network and sharing center
Change adapter settings.
Right click wireless adapter click status
Wireless properties.
Security tab.
Change my network settings
Reconnect to my network
The tablet has been fine until today. These steps above do not resolve the issue anymore.
THERE IS NO VIRUS PROTECTION BESIDES WHAT WINDOWS OFFERS ON THIS DEVICE!
Troubleshooting steps I have tried: deleting all the wlan profiles with

Change any properties one at a time that I thought might deal with this.
Removed all HP bloatware/3rd party connection managers.
Troubleshooting I tried last time:
Uninstalled and installed adapter drivers.
Tried the windows diagnose
Googlefu "Can't connect to this network" and you come up with a bunch of pages I have clicked on them and none of the solutions have worked.
Please if you have any solutions let me know! I am at my wits end with this dang thing.

These are all logical ideas, but alas I have already checked all of this. We do not have any blocking other than credentials(which are not locked and are correct). The amount of connections would be determined by how many IP Addresses that I have(which is
a ton). Not the wireless router, because we have many other devices that connect to it just fine. No mac filter. No the other pc isn't connected. No it is only connecting to one network.
I should mention that this is in an enterprise and not an at home network. It is a WAP not Wireless Router.

My ipad 2 can see my home wifi but I can't connect to the internet anymore ???

I can connect my Ipad to the encrypted network at home - but I can't connect to the internet anymore. In Safari, Itunes, email .... NOTHING ! Help pls.

You may not really be connected to your WiFi network.
Your router may not have given your iPad a valid IP address. Go to Settings > Wifi > your network name and touch the ">" to the right to see the network details. If the IP address starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Next, reset network settings on your iPad (Settings > General > Reset > Reset network settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
If you need more help please give more details on your network, i.e., your router make, model and version, the wifi security being used (WEP, WPA, WPA2), etc.

Can't connect to wireless network with Apple Computers (WRT54G)

Hi.
I have had a password protected router (WRT54G) for over two years that any pc will connect to if I give them the password. However, my roommate has an apple laptop and he can't connect, no matter how many times we try. I just got an ipod touch, and it can't connect to the network either. We are inputting our password correctly - why can't apple computers connect to my wireless network??
Again, my router is a WRT54G.
Thanks !!!

Make sure you enter the correct password...To check your Wireless Settings follow this link
If your Wireless Security is WEP then use WEP Key1 and not the Passphrase, make sure to enter a dollar sign on your Apple Computer when you attempt to connect...If your Wireless Security is WPA/WPA2 then use the WPA Shared key and no dollar sign is required...

Windows 10 Build 9926 - Can't connect to this network in certain networks

I have been asked to ask this question here. The original thread can be found at:

Hello
I have a Samsung 700T tablet.
Since I got the latest update 9926 I am having issues with my corporate network access. I have to type in my user name and password on the wireless connection. When I do I get "Can't connect to this network" message.
I have tried multiple drivers for the network card a "Intel(R) Centrino(R) Advanced-N 6235". I am currently using latest.
I am able to connect fine with my home Wifi.
On the "System" event log I get the following error message when I attempt to login no the WiFi.
"A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 42"
Any ideas?
I have checked and my card is set to use DHCP.
God bless,
Bruno

Have you tried talking to your system administrator? We had a fun bug in our Cisco wireless access points and wireless controller that would
kick Win 8+ machines from even trying to connect. A very long firmware and software update process fixed it.
--- answered back ----
Hello DatAsian,
Thank you for your response.
This is a very large wireless network, and as far that I know I am the only one having this issue. My other devices on the same cube work fine. The only difference is of course Windows 10. The other machines are Windows 8.1 and Windows 7.
In the past this was caused by a driver, but I have gotten about 6 different version of my wireless driver and they all have this issue.
I read on the troubleshoot about entering the wireless configuration manually by using the "Hidden network" screen. The instructions go:
2. Tax or click to connect to a network
3. Tap or click Hidden network tap or click Connect and then enter the network info.
I cannot find this "Hidden network" text on the "Connect to a network" screen. Am I missing something? Do I need to check something that allows me to connect to Hidden network?
One thing that I forgot to mention. I need to enter my user name and password when I enter this wireless network, since this is Employee Own device network.
Any other ideas?
God bless,
Bruno
When I use an android device I had to do the following changes to the way the device connected to wireless:
EAP Method: TTLS
Phase 2 Authentication: PAP
Then I have to use my user name and password.
Is there a way to set windows to the same type of authentication?
Please let me know.
God bless,
Bruno

Can't connect to external network

Switched from a Netgear router to a Cisco E2500 and now my Samsung blue ray won't connect to internet.
It says physical connection established but can't connect to external network.
Thank you for any help in this matter

Before I suggest you for any kind of troubleshooting steps, I would like to ask few questions. Let me know the name of the ISP. Leaving Samsung TV, do you have any computer which can access the internet wired and wireless? If yes, what IP address do you get in the computers?

HT4260 I did everything the article suggests. And for my macbook pro it works perfectly. But all the other devices (iphone 5, 4, Macbook Air) can't connect to the network. Anybody any idea's?

Try resetting your modem. Power it down. Wait a moment, then power it up again. While it resets, do not change what is connected to it.
In another, though unrelated article, Apple recommends the following:
If you have configured your Wi-Fi base stations in the past, it may be helpful to do a factory default reset of each Wi-Fi base station that will be part of the wireless extended network before you begin.
This step really ought not be considered optional for the configuration you propose. If the problem persists after resetting your modem, reset everything else too.

Can I connect to wireless networks far away?

How do I connect to wireless networks further away?
Is there a way I can improve my laptops wireless range so I can connect to wireless networks further away?

Hi!
You can only connect to wireless networks that the notebook recognizes. If the notebook recognizes a wireless network, you can connect to them. If it doesnt recognize (because it is further away) you can not connect.
Furthermore you can not improve the wireless range from the laptop. You can do this on a WLAN router, not on the notebook.
Bye

Can't connect to my network

I have used the same network with the same router for two years and it has always worked fine for my macook. 30 minutes ago I put my mac asleep, then I came back ten minutes later and I wasn't connect to my network anymore. I clicked on the airport symbol and there my network was. I click on it and the WPA password is saved, so I try to connect but it says: Anslutningen nådde en. That's Swedish and it means: The connection reached a. Nothing more! This happens every time I try to connect. What should I do?

I would first try to turn Airport Off and then back on. If that fails I would then try to reset the WiFi router. I would also check to see if my WiFi was set to a channel that was also being used by another WiFi in the area. If it was then I would change the change to one that was not being used.

Upgrade ip5 to ios6.0.2 and now I can't connect to the network (was fine with 6.0.1).

I just upgraded my ip5 to ios6.0.2 and now I can't connect to the network (was fine with 6.0.1). I bought the phone online in Canada but have a Hong Kong simcard. Any solution to connect to network?

I bought mine in the US and activated using a German SIM. It worked fine first on 6.0.1. After upgrading to 6.0.2 the SIM does not work. I have reset the reset the phone and still does not work. I loaded a new SIM and the phone worked for few minutes before going to Searching mode after I restarted the device. I am being told by the Genius Bar team that this is a Hardware failure.
