My internet connection is intermittent with my MBP but it's fine with my iPad. What's up with that?

Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article.
Step 2
If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it.
Step 4
This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration

from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

I know I can switch two iphone 4s's with SIM cards, but can I flip a CDMA iphone 4 (no SIM) with a 4s (has SIM)?

My wife wants to use my daughter's 4s phone instead of her CDMA iphone 4 with no SIM. Does verizon need to do the switch since I can't just switch SIM cards and restore from backup?

Unless the 4S was sold for Verizon, the CDMA module is disabled. Regardless, Verizon will not activate devices on their network that were not specifically sold for their network.

Slow wi-Fi internet connections and drop outs after MBP wakes up

Hello,
I have the new MBP 17 and recurring issues with the Aiport/Internet connections with my TC 500 Dual Band:
After the MBP wakes from sleep mode, I have recurring drop outs with regard to my internet connection. Airport connection shows me the full 4 bars and tells me I am connected, but Safari loads internet pages to no avail. I then usually deactivate my airport for 5 seconds, then reactivate it. The connection usually is better after that, but I do still have drop out issues every so often.
Anyone experiencing the same problem?
Would resetting SMC have any effect on this?
Thanks

I've had a similar problem at home - it's been exasperating.
It appears to be not just one thing but a collection of things causing the problems. The recent firmware update combined with driver updates in 10.5.6+ is one thing, but also there are some keychain issues, waking from sleep issues and interference issues.
When the MBP firmware was updated (10.5.6 / 10.5.7) I can't be sure exactly I noticed that my wi-fi signal was effected much more by interference. I'm using b/g as I have iPhones on the same network as my MBP at home. I ruled out router issues by testing with various other machines (Macs and PC's) - and on different wi-fi networks (my office).
The other machines didn't suffer the same problems at home and my machine did suffer the same problem at work,
I have a feeling that the driver / firmware update combined with several Airport Passwords (for the same network) appearing in your keychain conspired together to create the issue. When the Airport Signal dropped below a certain strength (by sleeping or by moving to another room) and there is a lot of interference from other wi-fi networks - your machine fails to reconnect correctly to your wi-fi network.
Often your network doesn't even show up in the available network lists. When it does - the keychain issue appears to cause a network timeout when re-connecting and therefore the connection fails and you get stuck in an annoying loop.
Moving my MBP close to the wi-fi router causes is to re-connect - which is why I believe it is related to signal strength. Also using a n only network rather than b/g helps considerably (n suffers from less interference). This however is not a fix as I have an iphone (which requires b/g) and I like to use my MBP more than 3 meters away from my wi-fi router.
Also on identical machines in my office (10.5.6 and 10.5.7) I didn't have the problem. The only real difference was those machines didn't sync with .mac and share the same keychain. Further more testing some of those machines on my home network they had no problems.
I tried loads and loads of things to fix this. In the end it wasn't one thing that did it, but a whole series of them.
1 - Delete all your Airport Passwords from your keychain.
2 - Ensure that if you are using .mac syncing you replace the .mac keychain from your current machine.
3 - Trash all your network preferences (including network interfaces and remembered networks)
4 - Zap your PRAM
5 - Resent your SMC
6 - Re-connect to your wi-fi network
And that appears to have worked for me. So far anyway.

Slow internet connect from home, nowhere else, and PC's are fine through home internet connection?

When I'm at my apartment with 18 mbps internet my MacBook Pro has absolutly no problems with the internet. When I come to my parents house to stay where they have 15 mbps internet my laptop is rediculously slow. I thought it was the fact that more people are connected but on every other device it works fine, my iPad and my parents PC's have no problem. I am at a complete loss I have tried to run a diagnostic multiple times and have done the DNS Servers 4.2.2.1. and 4.2.2.2 which helped slightly but there are points when the internet gives up, it just never loads. Does anyone have any suggestions?

I just synced with my MBP, but my iCloud account email address remains in a "inactive" status. Under settings the Apple ID and Password is wrong, and I can't find out how to fix it

I just switched over to an iPhone 4 CDMA on the verizon network the other day. I connected with my MBP/ w Lion and the sync seemed to go flawless.... All my date was pushed thru the iCloud, but then I saw that my main email address @me.com says that it is inactive when I look at it in Settings- Mail-Accounts. I can see that the iCloud account name and password is wrong, but I can not seem to find out how to correct it. Can anyone help me?
Thanks a lot,
Fred

You either have an incredibly complex computer setup or I think you are confusing terminology here. If you have iTunes set to share your library with others in your iTunes preferences then other computers in the area will see it as an item when they are running their iTunes and have it set to check for shared libraries. Your husband is probably seeing this when running iTunes on his computer. You can disable this sharing on your computer and/or he can set his not to pick up shared libraries.
By the way, an iTunes account is something you log into when you want to buy something from Apple. On your computer it is simply your iTunes collection or your iTunes application. So you need to turn off sharing in your iTunes application preferences.
Your husband is seeing "his" iTunes collection when running iTunes, but it is possible he doesn't have anything in it if it is a brand new computer.

Comcast Cable Internet not working with router (WRT54G), but network is fine?

My Comcast Cable Internet is not working with my router (WRT54G), but my home network is fine. The internet works without router.
I have a WRT54G Wireless-G Broadband Router from Linksys.
I was using Bellsouth DSL Internet up until two weeks ago.
I had my DSL modem connected to my router, and the router let me use the internet and share some files and printers with my laptop upstairs.
A few weeks ago we changed to Comcast cable. The technician came in and connected it himself, but only for the desktop. The internet worked perfectly, and still works perfectly on my desktop (the one downstairs). He didn't really give me any instruction or CD-roms for it.
When I tried connecting my router, the internet stopped working. It was weird because the router worked for the file sharing and printer sharing between both my computers, but the internet didn't work. Although, the light for the internet is lit on the router itself.
I even have this program called "AOL Network Magic" which shows a map of what is connected to the router, and it shows that the router and my laptop and desktop are connected, but then it has an "X" for the internet connection.
I have tried everything. I lost all of my CDs and things that came with Linksys, but I downloaded some guides from the Linksys website and it doesn't really help. I tried something called "NetSet", but after I set everything up it says my router is not compatible or something with NetSet. I read a bunch of FAQs, I tried going to comcast and seeing if they had any FAQS about it, but I can't find anything.
Maybe one of you can help me?
Also, I don't know my modem's IP address. I had it for Bellsouth, and sometimes when I would lose my connection I would go there and click on "reconnect" or something like that.
So the only way I can use the internet is to disconnect everything from my router and connect the ethernet cable directly to the modem.

You may open the web setup utility page of the router by typing its IP address on your browser's address bar. By default, it is 192.168.1.1. When you're asked for username, you may leave it blank. For password, its "admin". If in case that does not work, reset your router at the back for 30 secs and do a power cycle again, see if it becomes accessible after that...

HT201321 im having inconsistent internet connection on my macbook pro. But my other computers doesn't had this problem.do you guys had the same problem? after turning the wifi on and off, i'll have the connection again

Im having inconsistent internet connection with my macbookpro 13 inch. But if I turn off my wifi and turnit on again, it will come back again. Anyone had this problem?

Sig,
Thanks for the advice. I finally tried a solution after doing nothing. LoL. What I did do was change the channel the router was on from 9 to 7. I think I've done something like this in the past when I had slow internet and that worked out well too. I thought that would help and so far so good. Not an interruption so far but we shall see. To the guy or girl who expressed that they had the same problem as me I would try changing the channel of your router like I did. I will monitor the situation and see if it totally solved my problem or not and keep this thread updated. Thanks people

How share ADSL Internet connection to all machines without RRAS but using Windows Server DHCP and DNS

Hello!
I have this scenario on my small network with 10 PCs (connecting from outside to inside my network):
1) Modem with ADSL connection
2) Wireless Router with public IP on WAN interface
3) Switch
4) Server 2012 with DC/DHCP/DNS (with 2 NICs) and others servers/desktops machines
I want to share internet to servers and desktops.
I was able to share internet by 2 methods searching on google, but I am not satisfied with them:
First method - Using the Wireless Router and its DHCP Server
I turned on the DHCP inside the Wireless Router. All machines will get an IP and be able to go to Internet, but I don’t have the ability to control the DHCP and DNS in the router
how I would like to have, because the server DHCP and DNS must be turned off on Windows Server.
Second method - Using the Windows Server RRAS NAT, DHCP and DNS server
I have 2 NICs on the server:
NIC1 - CONNECTED TO SWITCH
IP: 192.168.1.1
MSK: 255.255.255.0
GTW:192.168.1.1
DNS:192.168.1.1
NIC2 - CONNECTED TO WIRELESS ROUTER
(the LAN IP of the wireless router is 172.16.0.1)
IP: 172.16.0.2
MSK: 255.255.0.0
GTW: 172.16.0.1
DNS: 172.16.0.1
After installing and setting the RRAS with NAT at the Server, the internet began to work on all machines but at some times the internet stop to load some
random webpages, and if you hit a couple of times the F5 button, the webpage open sometimes, but very, very slow.
I saw other people in foruns saying that RRAS is not very good, and could cause weird things at internet connection, so, now I think the internet is horrible
because of RRAS. After notice that internet is bad I tested it connecting a cable direct to the lan ports of the Wireless Router, and the internet works fast and perfect.
What is the best thing to do in my case to maintain Windows Server DHCP and DNS turned on and Internet be shared without loss of quality?
Thank you!

Hi,
please deploy according to this network topology. please turn off DHCP from router and use internal NAT function to share internet. Detailed configurations:
Router part:
LAN address: 192.168.1.1/24
DHCP part:
scope name : site name
address pool: 192.168.1.3-192.168.1.254
scope options:
router:192.168.1.1
DNS server:192.168.1.2
DNS part:
configure a forwarder to point to the public DNS address such as 8.8.8.8
with these settings, you can maintain Windows Server DHCP and DNS turned on and Internet be shared via hardware router.
Regards,
Mike

Internet connection problem- IP address from router, but will not connect

My Powerbook will connect to an open wireless network where I am and is assigned an appropriate IP address, but neither Mail nor Safari will connect properly. I know the system is working, because other people with wireless laptops can connect fine. I tried quitting everything and rebooting a number of times but no joy. I can't see anything in the settings that I can play with that will make a difference, but I can't understand why it won't connect.Very frustrating. Network diagnostics can't help either. I don't have access to the modem/router to reset it...

I'm having the same problem. I'm traveling and I was able to connect to the wireless network on my G4 Powerbook at the hotel this morning. Now I'm in a different location and I have a strong open wifi signal, but no internet connection. I can add that I also brought my iBook and it works fine on this network. Both worked just fine on this network back in October. I've tried in no particular order: rebooting (4x), Network Diagnostics in Safari ("N.D. cannot fix the current networking problems...make sure you are using the correct network settings"), creating a new user, comparing Network settings between the two Macs (the only difference is the last 3 digits of the IP assigned using DHCP), deleting preferences (airport, internetconnect, & networkConfig.plists, NetworkInterfaces & SystemConfiguration.plists), turning Airport off then back on, and setting up the iBook to share its internet connection. Internet Connect says that I'm connected to the network and have a full signal. Any other ideas?

I have a 2008 black macbook and access UK tv through a purchased proxy site. I want to buy a sony bravia internet connected tv to watch the channels in more comfort. Sony tell me this won't work - that the tv cannot capture my macbook content. Any advice?

I have a 2008 black MacBook and acess UK tv through a puchased proxy. I want to purchase a Sony Bravia internet connected tv and stream the site through a tv - Sony tell me this won't work - that a latest model tv cannot capture content and sites from a MacBook - is this true???? Surely there is a solution? Any help or advice welcome.

They are correct. The only stream you can wireless connect the TV to a Mac is through an AppleTV, and that's purchased content on iTunes, and your own homemade content that is H.264 MPEG-4 that is 1800kbps. Conversion of commercial video to that format is illegal, and hence how can not be stated on the forum. Alternatively, as long as the TV is HDMI, you can wired connect it to your MacBook using the same advice here:

Hi Lauren,
When troubleshooting power issues, we want to make sure we have followed all steps outlined in the following article:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
- Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- After at least 15 minutes, if:
               - The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
               - The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
               - Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
- If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
               - If the display turns on, go to step 4.
               - If the display remains black, go to next step.
- Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to
restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks,
Matt M.
