Trouble connecting to wireless network at work

I am having trouble connecting to a wireless network at work. Previously I have been able to connect to it, but today it says I'm connected but won't load any web pages.
In System Preferences under Network Status it says: "AirPort is connected to the network lynksys. AirPort has a self-assigned IP address and may not be able to connect to the Internet."
Any ideas? Thanks!

beckymagic, Welcome to the discussion area!
Many times this message is received when MAC address filtering has been enabled on the wireless base station. [This is also referred to as an "access list".] I suggest that you talk with the system admin and see if you need to add the MAC address of the AirPort card of your Mac to this list.

Can't connect to wireless network that works fine for other machines

I received my MacBook Pro last week (2.16 GHz) and I've been very happy with it so far. However, when I brought it home, I've had nothing but issues trying to connect to my wireless network. It's a Netgear, and you can read more about it at the following link:
http://www.netgear.com/products/details/WGT624.php
It works great with my Windows XP Desktop (HP Pavilion 1250n) and PowerBook G4. It works with no password, 40-bit WEP and 128-bit WEP. But not with the MacBook Pro. However, my MacBook Pro has worked at my office and StarBucks, so it works sometimes. Is there something special I have to set on my router for it to work with the MacBook Pro?

I also had problems with wireless connectivity while trying to access a netgear WGR614 albeit a v2 base station.
The problem was that I could not see the network from my MBP. It just didn't appear. The network was open with zero security. However my dell laptop was able to connect fine.
I noticed in the MBP config that the wireless locale was set to USA. I however live in Ireland. I then changed the locale inside the netgear 'wireless settings -> region' to United States. Now everything works fine. My dell didn't seem to care either way. It just picked up the new 'USA - region' based wireless network.
The problem now is that I travel quite a lot and usually I won't have the luxury of being able to change the routers configuration.
Is this just a MBP and Netgear WGR614 issue?
If this happens in the future is there a way for me to change the AirPort wireless card locale?

Having trouble connecting to wireless network

Hello. I am having some difficulties connecting to my Linksys router from my Powerbook G4. Here is my issue... sometimes airport can find the wireless connection (called Linksys) and sometimes it can't. I don't understand why it does sometimes, but other times it does not. I have a brand new iMac that is always able to find the network through the airport. I've never had problems with connecting the iMac to the wireless network, it's the Powerbook that will sometimes not find the wireless network in the drop down menu through airport. I don't understand how one computer can and one computer cannot. I was thinking maybe it's because the airport card is a bit older in the Powerbook and doesn't pick up as many networks, but like I said, some of the time it works just fine and it stays working until I shut down the laptop. Any ideas? I appreciate the help.

Try the following on your Powerbook:
1. Delete Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Delete the network(s) you regularly use from the list
2. Delete AirPort Keychain Entries
- Launch the "Keychain Access" application located in Applications/Utilties.
- Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
- Restart, or log out then back in.
3. Add Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Add the preferred network(s) using the "+" button.
- Restart or log out then back in.

MacBook trouble connecting to Wireless Network

I just purchased my MacBook and I am having trouble connecting to my wireless internet. My computer finds my router but when it prompts me for a password I put in the number at the bottom of my router and it says that "it cannot connect to the wireless internet". What can I change or do?

2Wire routers are VERY problematic with Macs.
A few people have gotten them to work.Many more,though,have not.
If you do a search for "2Wire Routers",you may find a workaround that suits you.
Personally,I would just pick up an "Airport Extreme" and be done with it.

Trouble Connecting To Wireless Network

Greetings,
New iTouch with the new 3.0 software installed.
iMac with Leopard 10.5.8
Using a Linksys Wireless Router WRT54G, settings:
- Home wireless network does not broadcast SSID
- WEP with 10-key password
- MAC filter enabled
Issue 1:
I entered my iTouch MAC address into the router's MAC filter list
Using the wireless on iTouch entered the SSID and Password
Result: Does not connect. What am I missing?
Issue 2:
Do I have to enter the network password every time or can I save the password in my ITouch?
Thanks for your help,
Matt

Thanks for the help,
So, my kids don't use the Internet function with their DS, and the Wii takes WPA . . .
I changed my wireless security settings to WPA2 with AES algorithms.
Still didn't work . . .
I then had to disable the MAC address filtering and . . . Presto! Connection Heaven.
Don't like having to had disabled my MAC address filtering though. I double checked the MAC in the list for the iTouch and it was fine.
Any known issues with the iTouch and MAC address filtering in wireless routers?
Thanks everyone,
Matt

Trouble connecting to wireless network with WRT610N

Need some help please. I have a WRT610N with 3 laptops that I am connecting to the network. I have been able to successfully connect 2 of them, but the third is a no go. I have the security set for WPA-TKIP, have a network code set; but when I enter the code on the one laptop and try to connect it won't do it. The laptop will connect via wired connection and will also connect wireless if I take the security off. Many times I have noticed the security settings on the laptop will change after I have save them; going from WPA-TKIP back to OPEN-WEP. I have tried everything, but no luck. The laptop is running Windows XP Home edition on a Sonay Vaio PCG K-15. Any help would be greatly appreciated. Thanks

Well try upgrading the firmware of the router & keep on holding tightly
the reset button in such a way that power light is blinking on the
router & then do a complete network power cycle i.e., unplug the power
cables from the modem & from the router & then plug in the power cable
to the modem first once all the lights are solid green you could plug
in the power cable to the router & check out it will definately work!!
Open the setup page of router using 192.168.1.1 then put in the password as admin...
all you need to do is do the wireless settings such as Radio Band Frequency to Standard 20 MHZ frequency,channel to 11.
Also,the advanced wireless settings to Beacon Interval=50,Frag
thres=2306 & Rts thres=2307 & then uncheck a Block Anonymous Internet
Requests & it will definately work!!!

Trouble connecting to wireless networks and slow connection.

For the past three weeks or so I've been experience difficulty connecting to networks I previously had no trouble connecting to. I'm only able to go about 15 feet or so away from a wireless router before my speed either drops through to the floor or the connection is lost entirely. I've tried looking through forums all over the internet, but I wondered if anybody had any insight into what I could do to get my wi-fi back up to speed?
Thanks!

Good Luck.

Trouble connecting to Wireless Network with T40

Hi,
My girlfriend and I are on vacation and renting an apartment with wireless access and though she is able to connect with her much newer laptop I am having trouble. My laptop is an IBM T40 (2373), running Win2000 with the following wireless card
Cisco Systems PCI Wireless LAN Adapter #2
Driver Provider Cisco
Driver Date 4-2-2002
Driver Version 3.4.9.0
We were given what they called a username (lets say ourusername) and a password (lets say ourpassword)
After she has connected if I look at her properties it shows on the connectin tab ourusername for both the name and ssid and on the security tab is shows securty type - no authentication, encryption type WEP and dots for the network security key which presumably correspond to the password which we were given and she was prompted for when she connected.
The problem is that if I look at the properties for my wireless connection there is no place to enter the password and no mention of WEP. Is the problem that my driver is too old (forgive the lack of a question mark, and some of the other strange punctuation - on top of everything else her keyboard is laid out for spanish and I cant find a many of the punctuation marks). I should mention that I know that my hardware works as I use this card on public access points all of the time. If anyone could point me in the right direction, I would really appreciate it.
Thanks in advance for any replies.

Trouble connecting to wireless networks

I have 15 inch MacBook Pro just got it in june all software up to date. My problem is that if i try to connect to a wireles network with WEP or WPA, and i am not the computer that has set up the network, i enter the correct password and it comes back incorrect password. Used to happen with my iMac G5 also. Apple has not been any help. They could not find anything wrong with the iMacs airport card, so I haven't let the mess with this macbook pro yet. Guy i talked to this week from apple said its because the airport is more advanced technology. Need some help or advice or something driving me nuts. ALWAYS says incorrect password

The only fix so to speak is to allow G and N over the Extreme. Lose of 5G only speed but allows connectivity to N.
Obviously this is a software glitch to repaired with an upgrade.

Tell us more about the problem, I can think up 100&1 different reasons, but don't have time to go through all the possibilities. So.. what happens?

Welcome to the Apple Community.
Assuming this is not the first time you have used your Apple TV
You might try restarting the Apple TV by removing ALL the cables for 30 seconds.
Also try restarting the router.
If the problem persists, try a restore, you may want to try the previous procedures several times before doing this.
If restoring from the Apple TV doesn't help, try restoring from iTunes using a USB cable.
If this is a new Apple TV, in addition to trying the above, it may also be that your network router is not allowing access to the timeserver, check that your router allows access over port 123.

My apple extreme wireless network is working fine with the macs but ios devices (iPhone & iPad) will not connect. I can see the network though. Everything was working until the ISP went down. Any suggestions?

My apple extreme wireless network is working fine with two Macs but ios devices (iPhone & iPad) will not connect. I can see the network and it's telling me I'm connected but Safari says I'm not connected to the internet. Everything was working until the ISP went down. Any suggestions?

Thank you, I've tried the support tips (resetting the network, checking security settings, etc.) and rebooting the network devices several times to no avail. I've actually been working on this for several days (when I can afford to have the network down).
What I have to determine is what has changed in the setup...from when it WAS working just fine with all devices.

I am having trouble connecting to my network all of a sudden. It is not an issue with the service/router. I keep getting kicked off and getting a ! in my airport... anyone know what's up with this?

I am having trouble connecting to my network all of a sudden. I am able to connect to other networks but not my own. It is not an issue with the service/router because other devices connect fine. I keep getting kicked off and getting a ! in my airport. Last time it happended I called apple and the suggested I wipe my HD and reinstall everything. I did and it did not work. One day I turned my laptop on and it connected no problem. Now it has kicked me off again. I tried resetting my IP address but that does not work either! Has anyone had this problem?

Try this:
Apple menu / System Preferences / Network.
Click Location: and select Edit Locations..
Click + (plus sign), and enter a name for the new location - anything will do.
Apply this.

Hp C4580 printer won't connect to wireless network, but see network is available.

I've sat through quite a few of the threads here with regard to photsmart C4580 printer not connecting to wireless network.
My issues started with a cartridge issue, which I resolved with a new cartridge, but only after trying out different solution offered on HP forum.
Now printer won't connect to my network which it has been connected to for over 2 years with no issues. The wireless network is working perfectly fine and I even printed out a HP photosmart C4500 series connectivity status and in this report printer can see the network I need to connect to.
I've tried downloading various programs from Scan doctor to complete install of all HP programs and even tried installing printer from Windows 7 "add a printer", but none can see this printer.
lastly I was hoping trying to locate IP address for printer which looks like it may help, but report says IP Address "not applicable".
I believe printer, wireless network and PC are working correctly, this there a way to switch printer to online so it can be seen.
Help would be great.

Hello there! Welcome to the forums @Cushionman ,
I noticed your post about the issues you are having with connecting the printer to your network. I am wanting to offer you my suggestion that might help you out!

I tried the "iwconfig wlan0 channel auto", but that didn't work. Here's the output of "lspci | grep -i net":
[root@mzws ~]# lspci | grep -i net
00:19.0 Ethernet controller: Intel Corporation 82567LF Gigabit Network Connection (rev 03)
03:00.0 Network controller: Intel Corporation WiFi Link 1000 Series
So what's the problem here? I searched the forum and google, and it seemed that I connected to a wrong router(for sometimes I only one "carrier lost" then "timed out"), but how was that happened? Things worked quite well before the upgrading as well as in my Windows environment.
Any reply would be appreciated! Thanks in advance!

Thanks Proofrific, but I believe it's not, for the DHCP server is a built-in module in my wireless router.
I am now able to connect to my wireless network now. And it seems to be a little kernel bug as I discovered a thread(sorry but I forgot which one) in the forum discussing a similar problem.... Somebody in that post suggested a work-around to change the channel, as their default setting is channel 13 or 12.
I tried and it did work! Just simply open your router's setting page and then change the channel from auto to 3(in my case), and netcfg worked well now. For the manual configuration, I suppose the "iwconfig wlan0 channel 3" should be issued.
Thanks everyone in the forum for providing their solutions!
