OSX 10.8.2 Tethering to iPhone4S wifi No Internet Connection

Hello,
Since upgrading something (OSX or iOS), I now have headaches when tethering my Macbook to my iPhone (both with latest versions).
I used to be able to select my iPhone in the wifi drop down, it would think about it for a few seconds, then connect with the tethered symbol (two linked rings).
Since updating something a while ago, now I get the alert symbol every time, and no internet connection. This is rectified by going into the wifi menu, running the troubleshooter, hitting next a few times and it suddenly will decide to work even though I haven't changed anything. I would like to know if anyone else is experiencing this problem when tethering over wifi.
I can use my phone with USB and there are no issues. I also connect to my home wifi network with no issues. It's just frustrating now that I have to take several extra pointless steps to make the connection work.
Cheers,
Steve

WiFi: No Internet Connection Issue

Please Help!!!
MacBook Pro 13 inch i5-processor, 4G memory, Late 2011 edition running Lion 10.7.3
I finally made the switch from PC to Mac... after I had way too many PC failures. Several told me that they have not experienced such frequent failures on Apple products.
However, I am very frustrated and second guessing whether I made the right choice... so asking someone to help.
I bought a MacBook Pro 2 weeks ago that worked great for a few days. Then the internet slowed down. I thought it would be my router. I checked out the connectiviy at other locations where the speeds were great (commercial locations). On a PC the connection was good but on my Mac it was slow. So checked out for an update. There was one, applied that and there was an improvement. But found out that if I put the Mac to sleep and do not shutdown the spped degrades over time. Well, for some reason a couple of days later the speeds 'took care of itself' !!!
Now I have a new problem for the past 4 days... that has limited me in my day-to-day work.
WiFi connects and finds the signal and connects but do not have any internet connection. Gives me an error "No Internet Connection". This is what I have done so far...
1) Connect a wired connection... internet is fine.
2) Took it to Geek Squad (Best Buy) they ran a command "sudo ifconfig..." fixed it and gave me the same commands to try next time. However, that does not work at all since then
3) Ran Network Diagnostics... no help
4) Turned WiFi Off and On along with Forgetting this Networks and Joining again. Done this with several combinations and multiple times... no dice
5) There was a recent update and applied that ... no help
I am close to giving up on a Mac altogether... please help...

Can someone please at least acknowledge if they are or have experienced this same problem?

Airport extreme takes long time to establish stable Wifi to Internet connection

Hi,
I am using Airport Extreme together with Airport express (to extend the Wifi signal). When I connect my MBP, MBA or my PC to the Wifi network it takes (in 90% of cases roughly) quite a long time - even up to 20mins - to get stable Internet connection. The connection drops due to time-outs or with "DNS server cannot be reached" messages. Connectivity on my local network is just fine and does not seem to show similar behavior. After some time all settles down and my connection is fast and stable. The strange thing is that my iPads are not affected by this - i.e. I can browse internet fast on my iPad, but my MBP cannot reach a single internet page at the same time. When I switch to wired connection, everything is just fine from the beginning - no time-outs etc. Sometimes it helps to switch the Airport Extreme off and on again, but it's about a 50/50 chance.
Anyone got an idea what's going on?
Thanks a lot for help!

You have wireless gremlins.. plus voodoo..
It is the nature of the beast.
My recommendation is to clean up, simplify and start over.
1. Reset the AE to factory and start over. This time use all short names no spaces and pure alphanumerics. Same for passwords but longer.
2. While you have problems try using different names for the two bands.. eg AE24ghz and AE5ghz
3. Use fixed channels.. 11, 8, 6 in that order for 2.4ghz and usually one low and one high for 5ghz.. say 36 and 149. (actual number depend on geo-region).
4. Reset the Express to factory and test extend on both the 2.4ghz and 5ghz.. (assuming gen2.. if gen1 just 2.4ghz). The express must get excellent signal to transmit excellent connection.. if it is poor then it will make things worse not better.
5. Use the apple wireless diagnostics.. to help you determine how the signal is in various parts of the house.
diagnostics
http://osxdaily.com/2012/07/31/wi-fi-scanner-mac-os-x-mountain-lion/
http://support.apple.com/en-au/HT202663
There are plenty of these available .. paid for and free but since it is built in give it a go.
6. Setup IPv6 to link-local only.
This setting is here.
7. In the client computers with issues.. clean out all current wireless names.. reboot the computer and rediscover the wireless again.. put in the password and set to remember the network.
With Yosemite.. wireless issues are a given.. expect them.. they are part of the deal.
You might even need to do a clean install of the OS.. any upgrade install to Yosemite with issues should be treated as so normal.. it is just always going to happen.

WiFi loosing internet connectivity

Hi,
I bought my iphone from ebay last week. Brand new and factory unlocked. It was shipped to me in South Africa.
I've been using it for a couple of days now and I noticed that the wifi is very dodgy. It connects 100% to my wifi network (which has WEP64 security and is connected via pppoe to the internet).
My iPhone does see the Wifi network, and joins without any problems. It also keeps the connection to the actual WiFi network without any problems, but it seems to loose the internet connectivity. When I browse Safari on my phone I keep on getting "Not connected to the Internet". Applications that require that internet doesn't work either. It works for 1min and then all of a sudden it says "No Internet connectivity".
It's actually very concerning the number of people having issues with WiFi.
I'm running OS 3.0.1 (And I'm not willing to upgrade due to jailbreak no working on 3.1) I've also read that 3.1 does infact NOT SOLVE THE PROBLEM with WiFi.
My question is, how do I go about having my iPhone accessed and replaced. I stay in south africa so will apple replace it here in south africa with a new one, or do I need to ship it back to USA?
Thanks

I have 2 x iPhones [supplied by Apple] both have been upgraded 3.0 to 3.01 and now 3.10 without any issues. Reading the threads on this issue it would be very easy to form the view that it is a hardware issue. If that is the case then you should have the same connectivity issues with any network which may be something you might like to try in order to establish the point of failure. Initially I had a similar problem with the router which was drawn to the router manufacturers attention which was resolved with an upgrade to the routers Firmware. I run WPA2 encryption without any issues on an 802.11/n 802.11/g [compatible] router. Good luck Ant..

I am going to buy an iPad2. May I use my iphone4s to gain internet connection to the ipad2?

May I gain internet acces for an ipad2 using my iphone4s?

That would depend upon who your cell service provider is and what level of service subscription you have.
If you have AT&T in the US, then you would need to get the Data Pro plus tethering ($45 for 4GB plus $10 for each additional GB over 4GB used) to get the wifi hotspot service on your iPhone 4S allowing ou to then use it as a wifi hotspot to conenct our iPad to the internet. Other cell providers have different options and costs...

HT4199 I use an IMAC thas has the latest version of OSX. Lately I have had problems with my internet connection...now I see that my airport card is turned off. How can I turn it back on...I have done the obvious things in the network menu...even gone to

I have an IMAC that uses OSX maverick (10.9..) I cannot connect to the internet because my airport card is turned off. I .have tried repeatedly to turn it on, ,going into assist in diagnostics, as well as the opening wireless menu. I am thinking the card might have died. How can I run diagnostics on the card? How can I fix the problem? Java mama

Click the Wi-Fi icon in your Mac's menu bar.
If it looks like this, it's off:
Click it and select Turn Wi-Fi On.
If it looks like this, it's already on but something else is wrong:
If it looks like something else, describe it or post a screenshot.

HT1657 Do I have to have wifi or Internet connection to watch a rented movie

Do I have to have an Internet connection to watch a rented movie on my iPad or I pod

Welcome to the Apple Community.
From my own personal experience, I have found that when I turn off the Wi-Fi on my Wi-Fi only iPad, I am still able to play rented movies on it. I have tried this perhaps four or five times and in each case, this has been the result. I have also noted that other users have had the same experience as I.
However saying that I have noted a small number of users that have stated they are unable to view rented movies without an Internet connection. This knowledge base article from Apple, also suggests that an Internet connection is required.

IMac slows down wifi/LAN cable connection

Hello,
I came across a quiet unique and annoying problem, that I have not seen being discussed so far.
I spend the last 3 weeks trying to solve my internet/wifi connection following all kinds of posts here.
Problem: Wifi/Lan internet connection is slow (less than 0.8mbit/s)
Problem only appears when I login with an iMac via wifi OR lag cable
iMac, 2011 27`` Mac OS 10.7.5
Background:
I have a 20mbit/s internet connection with my provider. works fine on iPad, iPhone, appleTV HTC one mini, etc… BUT as soon, as I login with my iMac, the internet connection slows down to less than 1 mbit/s
I have tried following solutions:
- live box (router) was exchanged and is brand new
- security settings on router changes (wpa2 etc)
- all channels on router tested from 1-13
- keychain saved passwords for Wifi and router deleted, PRAM reset
- renewed lease of connected devices (no IP conflict)
- shut down wifi on iMac - connection with all devices great, as soon as i switch wifi on, all devices lose their high speed connection and go down to less than 1mbit/s
- connected iMac via LAN cable: same problem, all speed is lost
- iMac is not in the network - speed is great
- connected iMac via time capsule wifi, same problem. connected iMac via netgear extender, same problem
also, if I open network preferences and start the "assist me" app and run diagnostics, all dots are green except the ISP and server, bit most of the time they switch to green immediately, but connection is still slow.
Reception bar is on "3", so signal strength is no problem, and I´d like to emphasize that this is also happening on LAN cable. and again, if the iMac is disconnected from wifi AND / OR LAN, all other devices work fine.
Would love to hear your thoughts!
Thanks!

Although I have been on Mac OS for a while now, I have never had to troubleshoot faulty network in the mac itself.
OSX does apparently have a safe mode boot..
OS X: What is Safe Boot, Safe Mode?
Try that.. as that gives you the same thing as windows with all the extras left out, so you get a basic operating system only and you can see if the problem still exists.. if it does.. I would simply bite the bullet.. wipe the Mac.. reinstall the OS and then carefully reinstall your applications from original disks/downloads and move your operating files back .. but start a different user on the computer and copy back the min you need to get working again.
If the problem still happens even in safe mode boot then do a hardware test.. because it is possible something has actually failed at the hardware level.

Internet connectivity drops when transitioning LTE/WiFi

I have an iPhone 5S 32G on Verizon using ios 8.1.1
Mail, messaging, browsing works using WiFi at home (known state). Ride to work phone is not in use and LTE connected. Get to work and phone connects to office WiFi. Internet connectivity (email hangs in 'Checking for mail...', iMessages do not arrive, etc.). Ending apps (flick off screen) and restarting does not work. Power down/up and WiFi again connects (and LTE) and internet connectivity is fine. Go out of office to lunch (WiFi drop, onto LTE) and intenet connectivity drops again. Power cycle, LTE comes up and connectivity fine.
Note this does not occur every time (sometimes I can go from home to work WiFi OK and vice-versa.) But it happens enough to be annoying. Silly to have to power cycle on transition. IIRC this was not an issue pre iOS 8.x series.
I have reset network settings, rebooted, turned WiFi on/off to no avail so far. Any ideas or anyone else seeing similar issue?

I am having the same problem. My MacBook, iPad, iPhone, and even the PC all lose internet connectivity;but home sharing still continues to function properly on ATV2.
I'm not too savvy on routers and modems, but could the problem be my router's capacity?

On the same iMac wifi can be connected in Win7 but not OSX Maverick

Hi All,
I'm encountering a problem of connecting to wifi on my new iMac. I'm wondering whether anyone in the community has also encountered the same problem.
My iMac is a late 2013 model with 21.7" display bought just 2 weeks again. The OSX installed is Maverick with the latest update. I have also installed Win7 using Bootcamp.
At the beginning, the wifi connection was OK both in OSX and Win7. However, just around 1 week ago, the network connection began to fail in OSX. When logging into the Win7, I can still connect to my router through the wifi and everything is OK. This at least can proves that the wireless adapter in the iMac itself doesn't malfunction and the router works fine. Also all the other devices in my home connects to the same router through wifi has no problem including 2 iPhone5, 1 iPhone4S, 1 iPhone4 and a MBA 2012 model.
However, whenever I switched to the OSX any try to connect to the wifi ends in a failure. The SSID of the network is displayed in the visible network list still but not connectable. By clicking the name and after a while for the iMac to try to connect, a message saying "network cannot be joined" will pop up. Even by running the network diagnosis and specifying a static ip address for the iMac won't help. And I have also tried out some tricks in the community but all seemed not work.
Really appreciate if someone can suggest and help.

MBP keeps crashing when using Internet Tethering with iPhone4

I have had 2 crashes today of my new 13" MBP (I7 CPU, 8 Gb RAM, SSD) while using Ethernet Tethering with iPhone4. This is really embarrassing. I have used PC all my life and this is my first Mac. It's been many years since I have seen Blue screen of death on my PC. I have always heard about super reliability of Mac and could not believed my eyes when I saw the black message. Software industry moved long way improving reliability but looks like Mac team is moving in other direction. Unacceptable!

Same with my MacBook Pro!
I was really upset with this issue.
I got it in early March 2011, just only one month and a few days.
I always connected via USB tethering, it did work.
The problem just started yesterday, it almost 10 times after connect internet.
I called to the technical support and they told me to update to 10.6.7 (Mine was 10.6.6)
Then I updated and it went well (which I found out later that cuz I use the WiFi to connected) for the rest of the day.
But after I came back home and connected via USB , it crashed again.
Then I decided to go to the store at 5th ave. , they checked for a 10 minutes and told me to backup all my data and take it back to them.
Let see what is going to happen next.

IPhone4 wifi connection not working

my iphone4 now no longer connects to the home wifi network or any other wireless network (so all data is provided trough 3G!!)
It picks up the wifi signal (the network is shown with a check/tick mark next to it) but the phone does not connect.
I have "forgotten network" "reset network settings" carried out a "full restore" and reset the phone to factory and still nothing....
When comparing to my girlfriend iPhone4 which has had firmware upgrade as well at the same time (exactly same phone purchased at same time) and yet seems to work no problems there is data missing in the "network settings" such at router.
Also the iPhone3Gs, MacBook Pro, Compaq etc in the house have no problems.
is it a hardware fault???

Is it a hardware fault???
Could be. The phone comes with a one year warranty, make an appointment at an Apple store. If your phone is determined to be faulty, it will be replaced on the spot.

IPhone4s slow Internet connection at my WiFi

My iMac is well connected to the Internet by using my WiFi. So the Internet connection is quite fast. But my iPhone4s and iPad1 (both are running on iOS5) are very slow when using the same WiFi.

lots of people having this problem, most of them talking on this thread here
