Macbook Can't Connect

My macbook (Intel Core Duo 2GHz) won't connect to a 802.11n 5GHz network. Why is this? but my imac (2.16 GHz Intel Core 2) will.
Thanks

My macbook (Intel Core Duo 2GHz) won't connect to a 802.11n 5GHz network. Why is this? but my imac (2.16 GHz Intel Core 2) will.
In order for your MacBook to connect to a 802.11n wireless network, it must be enabled for "n." However, your MacBook must have the Core 2 Duo processor to be eligible for upgrade.
The following Macs can be upgraded for "n."
o MacBook Pro with Intel Core 2 Duo
o MacBook with Intel Core 2 Duo
o Mac Pro with AirPort Extreme option
o iMac with Intel Core 2 Duo (except the 17-inch, 1.83GHz iMac)

Macbook can't connect to B110 printer by WiFi

Hi,
Whenever I enable WPA or WPA2 security on the WiFi, my Macbook will not be able to print/scan to the B110 printer via wireless network, though I can access the printer with the IP address at my browser and scan from the web interface. The PC at my home has no problem. Also, my Macbook can print/scan to the printer without any issue if no security is enabled for the wireless network. What's the solution?
I have tried all the suggested solutions, including reseting the printer in the pref, uninstall the HP software, but to no avail.
Config:
Mac OS X 10.6.6
Updated to the latest printer driver from HP (version 3.2)
Router: Level One WBR-6011
Thanks a lot for your help!
Richard
This question was solved.
View Solution.

Is this a router that is supplied by your ISP? Is it a DSL or FIOS service?
If so, let's reinstall the printer in this manner:
- Unplug the Internet line that runs between the router and the wall
- Turn the power off on the router, wait 30 seconds, then turn the power back on.
- Go through the normal process of connecting the printer to the router.
- Now find the IP address of the printer (it should be on the self-test printout), type it into a browser.
- On that screen you will find a Networking Tab, then on the left Wireless, then the IPv4 Tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you know what that is, set an IP outside that range but no higher than 254 (the last number in the address). If you do not know, use the current IP address.
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router IP (its on the self-test printout) in the Gateway and first DNS field, leave the second blank.
- Click 'Apply'
- Finally, plug in the Internet line, reboot the router and test.

Macbook can't connect via L2TP but can via PPTP. iPhone can connect to both

So I've been banging my head up against the wall for the better part of this morning trying to figure this out. Just as a note, I'm 3000 miles from my house and server, but I do have access to it for the time being via PPTP.
Before I left, I verified that I could connect with L2TP on my iphone's 3G network. I was also able to connect at the airport on my Macbook using L2TP. Sometime overnight something changed, and I can't figure out what. I noticed that my phone dropped it's VPN connection saying something like "the connection to the server dropped unexpectedly" or such. After that, I was unable to connect over L2TP on my macbook or iphone. On a whim I tried connecting over PPTP which worked! But only on my macbook. Again on a whim I tried to connect via L2TP on my iphone, and it worked?! I rinsed, lathered and repeated that process over and over again and confirmed that I could only connect over L2TP on my iPhone after connecting on my macbook over PPTP. Also, on my iphone, if I stored the password it wouldn't authenticate (probably not related).
As of this moment I am connected using L2TP on my iphone for the last hour, using it to successfully stream Pandora across US borders, but can't sustain a PPTP connection on my macbook for longer than 10 mins. And I still can't connect over L2TP. So that said here are the client and server logs (ips, domains and usernames masked....) Server and clients are in different timezones:

I'm having similar issues but not much luck getting any answers. I made a similar post here - maybe something in there will help you.
One thing I have been able to pinpoint is that the MobileMe Back To My Mac service was causing quite a few issues with being able to connect to the VPN. Once I turn off the service, connection seems to work fine. Although, once I'm connected, I cannot access file sharing. Still waiting for some answers on that.

Macbook can't connect with/to iMac

I've got an Mabook and an iMac, plus an airport extreme. Both can connect wireless to the internet, my iMac sees and connects with the macbook just fine, but when I try to connect my macbook to my imac it sees the imac (it shows up under 'shared' in finder, but it won't connect. It keeps on trying and after a good few minutes it just tells me the connection got reset or something like that. What can I do to have my macbook establishing a connection with my imac?

I've had this problem before... hopefully your fix is as simple as mine was.
You should double check the iMac's "Sharing" preference pane and make sure that file sharing is enabled. It's confusing because there is a "Guest" account set up so that everyone can get to the publicly accessible "shared" folders (that's why the iMac shows up on your MacBook's finder) but you won't be able to actually log into the iMac unless it has file sharing turned on.
I hope this helps!

Time capsule & external drive - Time Machine Back-up of two macbooks - Can't connect

My wife and I each have a macbook pro and want to back them up using Time Machine. I had my macbook and a time capsule for a while before she got her laptop, so I backed mine up to the Time capsule - no problems.
Now, I have purchased an external drive so that mine backs up onto the time capsule drive and hers is set to back up on the external drive due to space limitations.
However, with hers set up, my macbook can no longer see its original back-up file. Meaning that hers will back-up all the time, but mine can't ever connect.
Is there a different configuration / setting that I should try to make this work?
Help is greatly appreciated!

I don't follow how the change on one laptop can affect the other, unless they are networked together in some way.. how is the second laptop connected??
I suggest you reset Time Machine.. and rediscover the TC..
A4 here http://pondini.org/TM/Troubleshooting.html
If you upgraded to Lion or ML recently that is the issue.. reboot the TC and maybe the whole network to clear the old IP addresses.

My macbook can't connect with my iphone, my macbook can't connect with my iphone

can't connect my laptop mac book with my iphone 4, keep on telling me to unlock my iphone password, both iphone and laptop already logged in with my apple account!!

You can't do it because that is not, and has never been a feature of the iPhone. Bluetooth file sharing and bluetooth sync are not supported. The only thing for which you can use a bluetooth connection with a computer is tethering.

My macbook can't connect wirelessly but connects via ethernet cable

I've been going through the discussions in this forum and other info I could find online but I can't seem to fix it. I've only been using this old macbook provided by my employer for a couple of months and I've been having intermittent wireless connectivity issues.
Things to consider:
My network settings show I'm connected to the web but when I load a webpage it says web page not available.
I can connect fine when I plug it to the router via an ethernet cable.
There are other laptops running Windows which use the same connection and they have no problems connecting at all.
I've used diagnostics and restarted the router but its says it can't fix the problem.
I tried one fix before which worked by performing these steps:went to Open network preferences->selected the network name and clicked advanced. I added the network's IP address under DNS.
Details:
Macbook 2,1 model
Mac OS X version 10.6
using Aztech DSL605EW router
I'm not that well versed with the techinical jargon that usually comes with discussions so please excuse me if I will sound like I don't know what I'm talking about. Please feel free to ask for more details which I may have missed.
Appreciate any help that comes my way.

It's important to remember that even for the same location, the settings for cable and airport are quite separate. This means that the settings that work for cable aren't automatically copied across to the airport settings.
Since it works for cable, I suggest you go to Network Settings, select the ethernet cable connection, then location then Advanced. Now note all the settings for all the tabs. Play particular attention to the Proxies. Now come out of advanced, select the airport, go back into Advanced and copy all the settings across so they match up.
Good luck

MacBook can't connect Via Aiprport OR Ethernet.

Hi, I;m currently using ethernet though my PC. But the problem is:
1. When my Airport is connect to my X-Modem router. It has all green. But everyday it will stop with the internet but the light stays green. I have to Hard Reset it just to give it a chance to work.
2. When i plug the x-modem into my macbook via Ethernet, and try to access its HTML admin page. It never connects, but on my pc it does it instantly.
What can i do to fix it both?
Thanks. Mycael

You don't need to bump topics that are only an hour old. :P
What are the settings on your MB? Go in Sys Prefs -> Network and from the second drop down menu, select either Built-in Ethernet or AirPort. Have you selected DHCP in both the ethernet and AirPort settings?

MacBook can't connect to internet.

Help!
Hi guys,
I'm currently unable to connect to the internet via LAN cable on my MacBook though I have used it successfully in the past.
Normally I use wifi to connect to the internet with my MacBook and have had no problem. I'm currently giving the machine to my father whose residence does not have Wifi so I must use a LAN cable.
Previously I have connected to LAN and the system has connected to the internet for me automatically.
Having used Network preferences I've had no success.
I know this post is a bit vague. Any help would be appreciated as I'd like to give this MacBook to my father to use. Thank you.

Hi, Thank you, Sorry about that. I closed an old question about my iPad and just clicked post new comment, I don't use forums much and didn't realize it would post to this particular area. My mistake. Do you think I should repost the question to the other section?
The LAN line works on the PC laptop I have here and I am able to get all the router and LAN line information from it (IP address etc.) so I know the signal is active from the router.
When attached to the Macbook it says the cable is not connected.
However when I go into Applications - Utilities - Network Utility and click on info, it displays the ethernet and the Hardware address, and model. I can only assume that some communication from the hardware to the device occurred to place that information in my system as I didn't put it in manually.
any suggestions are greatly appreciated.

Macbook can't connect to internet any longer

I have a Verizon router but all of a sudden I can no longer connect to the internet. Every time I try to connect to the internet it tells me the connection has timed out. I tried the Network Setup Assistant, but it tells me my password is invalid, even though I am positive it's correct. Any suggestions?

Maybe a call to Verizon? SOunds like it may be on their end

New Macbook can't connect to IMAP

I have two Vista boxes on my home network that connect to an IMAP mail account without issues. I've entered the IMAP info into my Macbook Mail program but it hangs on the Incoming Mail Server after I click Continue. The message is:
Checking connections to mail server "mail.cygen.com"...
Any suggestions?

How did you fix it?
Was the SSL on the incoming server set automatically?
I still have the same problem.

Time Capsule woes -- Connection timeouts and can't connect with one Macbook

This is my second Time Capsule. Here's the scenario:
I have a Netopia 3347 DSL modem. That feeds into the Time Capsule in bridge mode. There is a MacBook (metal case), iBook (yes, it's old), two iphones, a color printer and an iPad that can all connect to the Time Capsule just fine. The problem is my MacBook can't connect. The offending computer is a 2.2Ghz Intel Core 2 Duo running SL 10.6.6. This computer can connect to the Netopia just fine, so I know its internal Airport works. After several go arounds with Apple tech support, I'm still nowhere.
Here are the symptoms:
1. I can see the TC's network SSID in the airport pull down menu. If I select the TC, a popup appears and asks for a password. If I enter the password, I'll get a connection timeout error.
2. On the rare occasions where it does connect, I can't open a webpage. Network diagnostics has red dots for ISP Internet and Server
3. On the even rarer occasions where it does connect, and I can access a webpage, it's unbearably slow, and the no-surf problem reappears after a few seconds. The red dots on the Network Diagnostics reappear.
Apple tech support was not helpful. I've power cycled everything a million times (and that doesn't explain why other computers can connect.) I know it's not my computer, because it can connect to the Netopia just fine.
I am STUMPED.

Magnificent! Problem solved... Isn't there a "this solved my problem" button somewhere?? Thanks and thanks again!

Can't connect to MacBook with Airport Extreme

I just swapped Airport Extreme base with new Airport Extreme 8012.N and now my Macbook can't connect to internet, keeps cutting out and dropping off. I have an iMac G5 connected via ethernet to Airport Extreme and Macbook in living room. It was working fine with old Airport Extreme router. I also have an Apple Express (not new 8012.N ) but it just blinks orange when plugged in. Any help would be appreciated.

You have to power down everything to start with. Make a clean slate so to speak.
I switched from an older Air Port Express to the new Extreme. Run the new software and when you power back up the new base station should show in the window. Follow the steps. It made me feel stupid the 1st time through and I had to do it again. You have to take your bent paperclip and reset.
After I got the new base station up and running I took the old Express and used it for Airtunes. At first it just blinked and wouldn't show up on the list of devices. I had to do the paperclip thing. And there it was! Green light! Follow the steps for Airtunes. Then I had to reconfigure my settings for my HP 3300 series wireless printer. That wasn't so bad, it all worked.
The machines all work well; we all just need pay close attention to the instructions.
I think that the Apple on line instructions could be a bit more clear. It all worked as it was supposed to but it was certainly a trial and error process.

Can't connect to 802.11 N AirPort network with Macbook Core Duo

So with my Airport Extreme, I set the router to be on 802.11n ONLY 2.5Ghz and my Macbook can't connect to it for some reason. But when I switch the configuration on my Extreme to 802.11n (802.11 b/g compatible) 2.5 Ghz, I'm able to connect with my Macbook.
I thought maybe the 802.11n enabler that came with the Extreme didn't work the first time I installed it on my computer so I tried to install it again but to no avail. I came to the conclusion that there was something wrong with my 802.11n capabilities on my Macbook by the test above, but can anyone thing of any other way to identify the problem? Can anyone think of a way to fix this problem?

To verify that 'n' capabilities are enabled:
Open Network Utility (found in the Applications > Utilities folder)
Under the Info Tab, choose Network Interface (en1)
In the section "Model: Wireless Network Adapter," if it says (802.11a/b/g/n), the 802.11n capability is installed. If it says (802.11a/b/g), you do not have the 802.11n capability.
If your MacBook has the "Core Duo" processor it does NOT have 802.11n hardware. Only the "Core 2 Duo" MacBooks have the 802.11n hardware.

Upgraded to 10.6.7 and now can't connect to wireless.

Hi,
I'm not the most experienced when it comes to this type of thing so I will try and be as detail as I can so that someone may be able to provide me with a solution.
I have a 13" MacBook (about 4 years old) and recently increased my RAM from 512mb to 2gb and installed Snow Leopard which connected to the internet fine, but I then performed some Software Updates so the system is now 10.6.7 and since then I haven't been able to connect to the internet. My router shows up in the click down menu for airport but it tries to connect for about 7 seconds and then says "Connection Timed Out", I can get on the internet perfectly fine on other computers and from my iPhone so I have no idea why the MacBook can't connect. My router is a "Belkin Adsl Modem with wireless-G router" model FSD7632-4 version 1000uk.
If anyone needs anymore information I will try and give it to you.
Many Thanks

I see you already have a correct answer, but you should try to avoid not having a secured network. My first advice would be to at least filter the MAC adresses of your know devices if your router support this feature. My second advice would be to try to secure your connection with WEP instead of WPA/WPA2, it is not as secure as WPA, but it is much better than no encryption and will probably work with all your wireless devices (my experience).
Cheers.
J.B.
