MBP problem connecting to wireless internet

I recently tried to get online using my Macbook Pro (Intel) and I was prompted for the password to access the wireless internet network which was unusual as it normally connected automatically every time. Once I had entered the correct password I was met with the pop up window "'There was an error connecting to the network 'Vlsise'" (Vlsise is the name of our home network). I think that this may have been due to recently downloading some updates the day before but I can't be sure.
I have an iMac (Intel) and PlayStation 3 which connect fine to the internet wirelessly but I've not gotten around to downloading the latest updates for the iMac in fear of it encountering the same problem as my MBP.
My laptop can connect via the ethernet cable but when I try to connect wirelessly I briefly see the IP Address 169.254.109.180 in the network settings window before the error message appears, if that is of any use.
The router I'm using is a 'Zyxel 660HW-T3' and has been great for the year that I've had it. It may also be worth pointing out that our provider 'Telefonica O2' upgraded our service last month but as the MBP is the only Mac that has a problem I can't really see this being related.
If anyone has a solution to my problem or any tips to try rectify the problem they would be greatly appreciated.
Thanks in advance.

So I took my MBP to work to try their WPA2 password protected network and it connected no problem! I'm absolutely stumped on this one I think my last resort will be to re-install OSX and see if that works. If someone else has already tried this and it didn't work then please inform me so that I can save myself the hassle.

When I try to download a movie it says it will be ready for viewing in 10 hours. I am connected to wireless internet. What is the problem?

When I try to download a movie it says it will be ready for viewing in 10 hours. I am connected to wireless internet. What is the problem?

How fast is your internet connection and do you know what wireless standard your router is? Because download time will depend on several factors. The 1st one being the speed of your connection,2) the size of the file being downloaded,& 3) how fast your router send and receieve the data.

Macbook pro just stopped connecting to wireless internet.

I have tried restarting it and deleting the old usernames and paswords, but nothing works. I thought it might be an internet problem but i am having the same problem at home and school.
Can anyone help me?

My macbook stopped connecting to wireless internet. Ive tried everything. HELP!
Open System Preferences then select the Network tab.
Cick Assist me... then click Diagnostics
If any of the buttons on the left are red click Continue.
That should help narrow down whether it's Wi-Fi or your settings or your ISP.
Might be something in this article you haven't tried yet > Troubleshooting Wi-Fi issues

I was having problems connecting to my internet at home with my 4s. I tried many of the suggestions. Nothing worked. I did not want to sit on the phone with apple etc trying to fix it. I bought a router extender. It worked like a charm.

I just want to let those of you who have problems connecting to home internet. I had same problem with my 4s iphone and tried many of the suggestions here as well as on the internet. Then I found something called an internet extender. Bought it and worked like a charm. It was worth the $60 I paid. No more hours of trying to figure it out. I don't know if this will work for anyone else with this problem but if it helps you I'm happy

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort Express base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the Express; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has initialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the Express will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options.
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the Express from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the Express. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the Express to the Internet broadband modem. For the 2nd generation Express, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.

We are on holiday in Mexico. Our iPad has no problem connecting to the Internet through a subscription WiFi network. But, both of our laptops can not with the same password. What can we try?

We are on holiday in Mexico. Our iPad2 has no problem connecting to the Internet through our hotel's subscription WiFi network. But, both of our macbookpros can not with the same password. What can we try?
We can join the network, but can not access the Internet. The password is correct. We have tried network assistant and diagnostics, restarting the laptops, re-joining the network. Our iPhone 4s also works all the time.
Same location. Signal strength is good.

Since I couldn't figure out a way to edit our original post, here's another potential clue.
Our laptops, when in System Preferences>Network, say "WiFi has the self-assigned IP address of XXXXXXXXX and will not be able to connect to the Internet".
Strangely, my six year old MBP running OS 10.6.8 accessed the Internet straight away, just by opening Safari to my home page. My wife's six month old MBP running OS 10.7.2 could not.

Difficult to connect to wireless internet

Hello,
I hope someone can help. I've been looking through these boards for days and nothing seems to work.
I am usually not able to connect to wireless internet if my macbook is more than about 10 feet away from my time capsule. However, SOMETIMES I am able to get a strong signal from another room - adding to my frustration.
Here are its current settings:
Firmware 7.4.2 (I've tried all versions from 7.3.2 on - no noticeable difference)
Connected to modem via ethernet.
Radio mode 802.11n (802.11b/g compatible)
Cannot install Airport Extreme Update 2007 002 because my hard drive does not meet volume requirements (???).
Therefore cannot install Airport Extreme 802.11n Enabler.
TC is set to a unique channel according to iStumbler. Minimal interference.
Many thanks for your suggestions.
Paul

Wireless devices in the U.S. must by law, operate on either 2.4 GHz or 5 GHz. The vast majority of wireless networks are running at the 2.4 GHz frequency, which is one of the same frequencies that cordless phones have been assigned.
I can't speak for Apple, but it's fair to say that they and all other manufacturers are limited to what they can do and have no control over that. The airways are already overcrowded and it will get much worse.
Your Time Capsule is capable of creating a wireless network at 5 GHz, so it's worth a try to see if that might solve your interference issues at 2.4 GHZ. There are far fewer networks in this range and cordless phones in general will not conflict with this frequency.
Open AirPort Utility
Click Manual Setup
Click the Wireless tab just below the row of icons
Look for the Radio Mode setting and choose something like 802.11n only at 5 GHz.
Update settings
The downside here is that older devices that operate on "g" speed will not be able to connect. I couldn't tell from your post whether you might have other devices there besides your Time Capsule and MacBook. I'm not sure if the MacBook will connect if it's more than a few years old, but worth a try.
Post back when you have had a chance to experiment.

Hello @vernell1,
Welcome to the HP forums.
I understand that your Photosmart Premium is not able to connect to the internet.
I would like to help.
Sometimes simply turning the printer off then back on will clear the problem.
Chances are you have already done this.
I would try setting a manual DNS.
The following post by happytohelp01 has instructions to set the manual DNS.
It describes a Photosmart 7510 but the steps should be very similar.
Efax 7510 still won't work after turning off/on ePrint several times
If you encounter any problems along the way, please let me know.

After recent apple update MBP will not connect to wireless internet

After running recent Security and Airport upgrades my Mac Book Pro (Intel) will not connect to wireless home router supplied by Verizon (GTE) and several public wi-fi's. Cannot get IP but sees networks. My iMac PPC still works fine. Prior to upgrade everything worked fine at home and abroad to other public wi-fi's. MBP still connects at work with AppleBase wireless. Can the upgrade be removed? Is there a simple fix? Should I wait for apple to fix this and break something else.... If not broken don't fix it..

I'm having similar issues.
I have 2 MBP's. The newest one is about 1 month old and has never been able to connect to a WPA network. The older MBP is 20 months old and was originally installed with Tiger and gradually updated via Software Update and a retail copy of Leopard and subsequent Software Update updates to 10.5.2. Interestingly, this MBP was always able to access my WPA network until I decided to do an erase and install. I installed the retail copy of Leopard and was subsequently unable to access my WPA network. So, I went back to my Tiger install disks - but I'm guessing that whatever Leopard did *possibly* updated the firmware of the airport card as, even under Tiger, I could not access my WPA network (yes, I agree it seems unlikely that an OS update would/should update firmware but I am grasping at straws).
Trying to further understand the problem , I noted that the Network utility in System preferences would always show either a connection error or a connection timeout whenever I attempted to join my WPA network. I turned on syslog in my router and attempted to rejoin the network and saw the following errors:

Any ideas as to where my investigations could progress? (The router manufacturer tells me that the WPA timeout handler is not configurable on the router).

I have a 4s from verizon. I always have trouble connecting to wireless internet. Keeps saying unable to join network. My husband has a 4 and has no trouble. What is my problem?

I have a 4s from verizon. Husband has a 4. He connects to wireless no problem. I always have trouble and cant get on. Message always says unable to join. What is my problem, faulty phone?

Hi Hogdays,
I know how frustrating it is not to be able to connect to the internet.
Below are the troubleshooting steps to try to figure out why:
iOS: Troubleshooting Wi-Fi networks and connections
I would follow the steps in order, but this section is specific to your error message:
If you're unable to join a nearby Wi-Fi network
Try restarting your Wi-Fi router by turning it off and then on again.
Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
When joining an 802.11n Wi-Fi network, ensure that your router is properly configured. See this article for more information.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings, including passwords, VPN, and APN settings.
Hope this helps ....

I cannot connect to the internet. I think I have my settings all out of whack now and need to get them back to the way they were when it was working. (I know my wireless router is working because my Dell has no problem connecting to the internet.)

I cannot connect to the internet on my iMac through my wireless router. I think I screwed up the settings and need to reset them. I know the router is working because I can access the internet on my Dell laptop which is located right next to my Mac.

On your iMac try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
In the windows on the left side: Select login for Keychains and "All Items" for Category.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

New MBP logic board and wireless internet does not work anymore

hi there
i had to change the logic board in my only 2 years old MBP15". i purchased a new one and put it in by myself (relatively easy task). i still use the same internal HD as this one still works fine, so all data are the same.
however, the new logic board has obviously a different "identity" from my old one, it came with a sticker which says "ethernet ID 001FF3513E7A" which is different from before. this may be the reason i can still access my wireless network at home, but the self assigned IP address prevents me from connecting to the internet. all settings are as before and it worked always without a problem.
all settings were "automatic" before (using DHCP), and i use exactly the same settings again, but no success. i have to add that i use a new mac mini in the same network with absolutely identical settings (automatic) and this one receives a free IP address from the router (which is only in the last number different from the router's), but the MBP shows a totally different IP address.
i could finally fix it switching to "manual" and adding the same IP address the mini is using and just changed the last number, which has to be different from the time capsule i use as wireless device and the mini. like this everything works just fine.
but why does the mac mini perform everything automatic and the MBP (even with the new ethernet ID - and especially since i connect wireless and not using ethernet) is not able to do so?
i worry if i want to use the internet in any wifi hot spot i may run into troubles...
any idea what the difference between these two machines (with identical settings) is?
thanks and cheers
george

Thank you. It didn't work unfortunately :((
Here are my router's details (Huawei):
Product name HG655b
Device ID 00E0FC-21530307237S0B028701
Hardware version VER.C
Firmware version V100R001C02B018
Batch number RWC3P0.010.29066
Physical address 5C:4C:A9:A5:41:B0
System up time 0 days 0 hours 15 minutes 56 seconds
I don't have Mac filtering enabled.
Now it doesn't even find the wireless network anymore...
My computer and itouch are connected to WAP, but the iphone could not connect to WAP, but only WEP.
Any other ideas?
Thanks a lot!

MacBook Pro can't connect to wireless internet

I have a MacBook Pro that I have had from about 3 years now. It's been great but earlier this week, it wasn't able to connect to the internet here at my school (college). I didn't think too much of it because my schools internet is always spotty and goes down from time to time. Yet when I go on to my computer tonight nothing I do with my airport or computer will get my webpages to say anything other than "Server not found". I tried turning off my airport then back on and reselecting my network because usually that helps. It would say it connected and I would have full bars but still the same error message. I tried again, and when I did it this time, I did it from within the system/network preferences. When I did this, I watched the connection of my airport go red, then I would connect and it would go to yellow saying I had no IP address. I would then sit and wait and eventually it would fully connect giving me the green go-a-head. But, again when I would open up my internet, I would get the "Sever not found" message. I would then quit my firefox all together and tried again that way and still same massage. I restarted my computer and tried again...nothing. I became more concerned because my roommate could get on the internet just fine and I could use the wireless in my room through my phone. I was consered that now this was a matter with my computer and not just the internet, so to make sure I got out my ethernet cable and hooked it up with my connection in my room. This would work!
So my question is...
My roommate brought up the possiblity that this problem is with some sort of chip in my computer that helps me connect wirelessly to the internet and that it has gone bad and needs to be replaced. It this so? or is there something else I need to be doing? (and I have been trying lots of thing) This is vital to me getting my work done because we are in the middle of the semester and I need my wireless!!
Please help!
Thanks!

thats... odd
thats a real world IP address. So that means you dont have an actual router doing NAT.
It's also very unsecure. I HIGHLY advise tweaking your home network very soon. Without alot more info theres not much that I can really advise though.
You said your roommate can get on the wireless fine - what IP address does he/she get?
Also, i think you said if you plug in with a physical wire it works as well - what IP address there?
Do you know if you have an actual router? Or is this simply a cable or dsl modem?

TV no longer connects to wireless internet after installation of Airport Time Capsule

TV no longer connects to wireless Wi-Fi internet after installation of AirPort Time Capsule.

I am having a similar problem with a new TIme Capsule. The wifi on the Time Capsule was working fine for months with all devices, iPhone 4s, iPad Air, iMac Air, Mac mini, and vizio smart TVs. After a recent software update the Time capsule wifi no longer connects to the smart tvs or the iPhones. It still connects to the mac mini, iPad and iMac Air. I do NOT think the software update timing was just coincidental. But I have not found any information or other users confirming a similar problem on the Apple support site.

Can't connect to wireless internet with Virgin

Installed Virgin media three weeks' ago and have not been able to use the wireless internet since. We have had 2 modems and 2 routers and spent about 12 hours talking to various people at Virgin but still does not work. Had AOL before with no probs. We have been able to connect it a couple of times but as soon as we turn off the mac, it loses the connection. Works fine on the modem with the ethernet cable. A lot of the time we can't even see the router on the airport but when we can and we try to connect, it just comes up with 'timed out'. The routers we have are D-Link and Netgear. Has anyone else had a similar problem? I'm just wondering if it is a problem with the Mac but we can connect to neighbours' unsecured networks. Please help!

thanks for your help, but sadly this did not work. even when i click the wireless airport icon on the top taskbar, no networks show up on the pull down menu. the only option i have is 'other.' shouldn't my secured network at least show up in the pull down menu, to which i provide the password?
is there any way to get this extreme card to work? has anyone else had this same problem with their iMac G5? this is ridiculous, thanks.

Can't connect to wireless internet with my airport extreme card.

hello, i need some help connecting to our wireless router. i do not have an airport base station, i am trying to connect to a third-party, secure wireless network. anyway, i've called apple, i've called linksys (the router company), and i am still using hardwire connected to the router. whenever i click the airport icon on the top taskbar, no networks show up. i have had my pc laptop in the same room as my iMac G5, and the laptop can autmatically connect to the network, but my iMac cannot. i am running out of options. i connect with a secure, wireless internet. its wep, whatever that means, and i've tried my user name and passcode numerous times, but to no avail. what do i do????

thanks for your help, but sadly this did not work. even when i click the wireless airport icon on the top taskbar, no networks show up on the pull down menu. the only option i have is 'other.' shouldn't my secured network at least show up in the pull down menu, to which i provide the password?
