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?

My brand new mac pro always had Internet connection issues at school. WHY is that? I see the school's Internet working perfectly fine on other PC's, but there is never a day where my mac doesn't have Internet connection issues at school. How do I fix it?

I got my mac pro in the middle of August. School started the week after. Internet was working perfectly fine at home. But at school, I never had a good connection. Sometimes on the good days I get a connection when I'm sitting at the exact spot in class I always sit at. It's ridiculous and it's frustrating. I invested my money into this laptop and I'm beginning to regret it. I thought it was the school's Internet, but I don't see Internet issues with other PC users. It's most frustrating on registration days and I'm trying to register for my classes before it gets taken, but again... Internet connection issues. It's random. Majority of the time, it doesn't work at all. I've done Network Diagnosis and turning WiFi off then turning it on again. I've done everything I could. I put my money on this laptop and it was a lot of money. I could have bought an 800 dollars laptop and I would have Internet connection anywhere on campus. So, I don't want to continue everyday to regret on buying this laptop every time I try to connect to the Internet at school or Starbucks or anywhere else. How do I fix this? What's the problem ?
At school, I heard this guy had a problem with Internet connections too and he owned a new mac book pro. He said something like Apple messed up on something, but he fixed it. If I knew mac book pro's had these issues I wouldn't have bought it in the first place. It's freezing on me every other day. It's ridiculous. But what concerns me the most is the Internet connection. So someone please tell me what can I do next to prevent the problem? Am I doing something wrong maybe?

Hi Kevin,
I'm using an XLR input mic which is connected to the phantom power enabled XLR mic socket on a USB M-Audio M-Track. The M-Track is connected by USB to the Mac Pro - so effectively I've got an M-Audio USB soundcard with a mic input. I've also tried a microphone that is a straight XLR to USB cable (guessing with some soundcard chip buried in the usb plug) but that also yields the same effect of bad latency, intermittent quality, stuttering and repeating and echoing (without the speakers on during record so its not feedback).
The mic works absolutely fine with other recording applications I have on the mac at the moment - albeit non-adobe ones (tested it on the EasyAudioRecorder - and it lives up to its name. it's easy)
I will try with Audition and report back, but sitting here right now I can imagine it would work fine with audition too - it just seems to be the way premiere is set up for recording into the timeline is a bit sketchy. I'm willing to accept it might well be a quirk with the new Mac Pro trashcan - I'm not weighting all the woes on premiere.
Any thoughts or am I out of luck to sit with my fingers crossed for a fix in the next round of updates?
Nathan.

TS1317 Internet Connectivity Issue - specifically with the DNS settings

Hi there,
I'm wondering if someone can help me resolve an internet connectivity issue on my MacBook Pro.
It appears to be a problem specifically with the DNS settings. I am connected to the internet but can only reach a website by typing in the IP address, not the domain name. The error messahe says: "Unable to resolve server's DNS address."
Regardless of whether I use Wifi, 3G modem or cable, i get the same error.
Operating System is Mac OSX Version 10.6.7
Please help!
Thanks

It sounds like your MacBook Pro has either incorrect or missing DNS IP address information in it network profile. Let's start with your wireless connection. You would find these in System Preferences > Network > Wi-Fi > Advanced > DNS tab
If your main Internet router is performing as the DHCP server, it would provide the DNS IP addresses (typically from your ISP) on this tab. You may have two or more addresses listed. If they are grayed, that means that the addresses are coming from the DHCP server.
In the following example screen shot, I am using DNS servers provided by OpenDNS. Notice that they are grayed as they are being provided by my main Internet router. Again, these should be either ones provided by your ISP or ones you purposely set up, like my OpenDNS ones.

4S Verizon Network / Internet Connectivity Issues?

I have been having problems with what appears to be Verizon Network/Internet Connectivity issues. I am located in northern Colorado, using an iPhone 4S with a Mophie Air battery backup/case.
I am in a solid 4G area (even though the phone is 3G) and I have not had any problems with any connection issues, until last night. I still see three bars of 3G service on the phone indicator area...so it is decieving.
I can still recieve emails, text messages, and phone calls, but nothing that uses the internet will work. All apps seem to try to open and try to update, but the whizzy-wheel indicator just sits and spins until I get a "Network Error" message or a time out error of some kind. Most error pop-ups are saying to check the internet settings and try again. Ugh!
Also, since it seems to be trying to recognize the network all the time (even when all tasks are killed and nothing should be running), my battery is going down MUCH faster today! I took it off of the charger at 7am and it was down to 20% battery in only 4 hours! Then I turned on the battery backup, and it is quickly using that up too! At this rate my phone will be completely DEAD by the time I leave work today, and I haven't even used it for anything all day (except to try to connect to the web a few times - testing)!
I have tried the following so far to try to regain internet through the Verizon network, to no avail:
checked for software updates...phone was up to date with iOS 6.0.1
checked my firmware version (it is 3.0.04)
killed all background/running apps (with the home button double-click/hold icon/end)
"reset" my phone via a couple of methods (both the regular power off option and the force-power off option).
*228, option 2 (to reset Roaming)
cleared all data cache areas/cookies/etc.
Cellular data is set to "On"; Roaming is set to "On" for all options;
I have a 64GB device (57.3 usable capacity) of which I still show 46.2 available.
WiFi is set to "Off" (although I can use WiFi at home with no problem if I need to, but I shouldn't have to!)
Airplane Mode is set to "Off"; Restrictions are set to "Off"; Bluetooth is set to "Off"
Basically, there is NO REASON my phone should be having connection issues!
PLEASE HELP?!!

I tried everything you did and more, i thought i had it working, but i got a voicemail today and when i went to open it earlier it just has the wheel loading forever and then says it cant onnect to voicemail. the searching does make it wear down the battery faster as well. i can get calls, texts etc, but i cant help but think there are a few bugs with the ios 6.01 software

Internet connectivity issues on Mac

I was wondering if there was any solution to an internet connectivity issue I'm having on a mac. It seemed to start when I purchased a new modem: an iPrimus AudioCodes MP252 wireless router. Basically the internet connection will either drop out or become stagnant/very slow. There have been no connection/speed issues on any Windows PC or laptop, but often when you try to use the internet on the mac it precipitates a network dropout, thus affecting the connection on Windows computers as well.
I'm trying to see if there's anything else that can be done besides taking it in to be serviced. ISP support hasn't been able to fix the issue, so perhaps it is some sort of compatibility issue between that particular modem and Apple Macs. Obviously the last resort is buying a new modem.
Modem: AudioCodes MP252 Series wireless router
Mac: Mac OS X Version 10.6.8

Hi, some Modems/Routers only like Windows PCs, also see if QoS is running on it giving most resources to PCs.

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

If that doesn't work try changing channels on your Router.

Internet Connectivity Issues

By process of elimination, I may have the right source of my problem, but may not!
Recently purchased a Time Capsule, primarily to replace my old Airport Extreme and extend its effective range within a new house. At the same time, I upgraded my iMac OS to Snow Leopard (so maybe this has caused a problem?!)
In the last few days have been having severe internet connectivity issues - either v slow speeds or so slow that Mail and/or Safari times out. My ISP tells me that their lines are working fine (I know they would say that, wouldn't they) and, admittedly, my old Powerbook (connected to the Airport network and onto the DSL router) is running Internet applications fine. So somthing seems to be wrong with the iMac or its setup.
Have run Network Diagnostics which tell me there's no problem (except it's still really slow!) and have obviously rebooted repeatedly (including the router and Time Capsule).
Any ideas?

Hello AnaB4,
Welcome to the HP Support Forums!
I see that you are getting a message to connect to server to update ink levels when printing with the 8620. This has been an issue since the weekend, server problems have been noted as the cause. The only resolution I know of at this time is to follow the steps here: Re: How do I correct the date on my HP Envy 4500?, or keep hitting OK.

EA6900 Internet Connection Issue - Desktop connected via ethernet cable

Hi there,
I have an HP p6837c, 64-bit OS with Windows 7 Home Premium. It is directly connected to the EA6900 via ethernet cable. My internet connection constantly drops (as in variably every 5 seconds to 5 minutes) then re-establishes itself. I have no internet connection issues when directly connected to the modem. All of the wirelss devices that are connected via the EA6900 are working without any issue. My husband's laptop, which has Windows 8.1, functions with no problem when directly connected to the EA6900 via ethernet cable. We've tried swapping out the cable. We've tried adjusting the MTUs per Support's suggestion. Nothing has solved the issue
Any thoughts on what the issues might be? Settings? The version of Windows? Any help would be much appreciated!

Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router and PC, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
Router and Wired Configurations
Setup DHCP reserved IP addresses for all devices ON the router. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
Ensure devices are set to auto obtain an IP address.
If http://en.wikipedia.org/wiki/Ipv6 is an option on the router, select Local Connection Only.
PC 3rd Party Security Software Configurations
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

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.

HT1695 iPad 3 iOS6 upgrade internet connectivity issue

I just upgraded my WIFI only new iPad to iOS 6 and as soon as it finished the install it lost connection with my wireless network. It recognizes the network and I can even inter the password, but then it says unable to connect. How do I fix this issue since I cannot even exit the setup for iOS 6 without an internet connection?
When I upgraded my iPhone 4s today to iOS 6 I also noticed that it is also unable to connect to my wifi, however, my laptop, playstation, etc connect just fine (its not a router issue).
Please help.

Help
I am also having this exact problem. I am unable to connect to my FIOS wifi router (which I usually have disabled) but am unable to connect to my Netgear WG102 Access Point - with WPA2 or no security - I get the same error message - unable to connect
Apple.....I think you guys have F#$%ED up with whatever you did. All my other devices on IOS5 work, but my IOS6 devices now do not work with Netgear.

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

Internet Connectivity issue on my MacBook Air using Time Capsule.

My brand new Air has a connectivy problem on my home network. My iMac, iPhone 4 and iPad all use the same time capsule network with no drop of Internet. My air is showing full strength wifi signal but it loses the Internet connection every 5 minutes or so, and reconnects after 3 or 4 minutes with no help from me.
The Air shows no such problems using the office wifi network.
Please help! The Air is 4 days old and might be heading back to the iStore (or off the balcony) if I can't solve the issue soon.
Many thanks

Internet connectivity issues with SA 520W router

Hi,
We have configured Cisco Small Business Pro (SA 520W) in a small office and all computers are connected with wifi. We are facing following problems:
1. Computer is connected with network and 100% signals available but there is no internet. After repairing network from computer or sometimes rebooting computer fix the this problem. What cause internet connectivity problem?
2. Sometimes computer is connected with internet and everything work fine but suddenly there is no internet. May be internet come back again after 2 minutes etc. Strange behavior.
3. Sometime there is no internet connection even after trying all possible tuneing but internet connection become alive again if we reboot router.
All these problems appear randomly on different computers. Can anyone tell what's the reason of all these problems and how can fix it?
Thanks.
Sajjad

I have the just similar problem since few days , for long time I have no issues with wireless router
I have five static IP addresses I am using 1 static IP for the Router and other for the internal use
I though it was my inter provider technical issue,
The internet is working through provider gateway router but not through a Cisco SA520W
some times it works some time it wont resolve host name, internal LAN works perfect ,but internet drops packets and it is very slow
If we dynamically setup the router, it works but not for the static IP address
my old configuration is not saved , reset to factory defaults even then it did not work
I do have 24 port cisco switch when I login there is no gui console just blank blue screen with text boxes
I appreciate some can guide.
I believe we need the update firmware on both devices .I appreciate for the help
Thanks

Internet Connectivity Issues, 511 CPU Fan not detected

Hello,
I have been experiencing some issues with my HP ENVY Pohenix 800-060 (running Windows 8.1) PC lately.
My internet connectivity has been acting crazy. Pages won't load fully. For example, when I am on Facebook I can't scroll down and have more posts load. I have to hit refresh and sometimes it will let me scroll down further than before. To load sites sometimes I have to hit refresh. If I am using just the wifi I am constantly connecting and disconnecting at totally random intervals but it's stable if I use an ethernet cable (however the other issues still persist). Images won't load fully as seen here
Also, starting yesterday when I restart my computer I get an error message that says 511 CPU fan not detected. I have opened my computer and dusted the fan and I have also unplugged it and plugged it back in to the motherboard to make sure it's securely connected. What's strange is that this only happens about 8 out of 10 times when I start my computer, and if it does happen I can simply touch the fan to get it started and it will work just fine until I turn my computer off.
I noticed in the HP Support Assistant that if you update to Windows 8.1 it says that you may experience internet connectivity loss and hardware problems so I don't know if these problems are related or not. I have checked and my drivers are up to date according to the HP website that searches for updates for you.
I am currently backing up my computer and plan on resetting it to factory default if I can't find the source of these problems.

Eldrscrolls, welcome to the forum.
Please check the CPU fan thoroughly before using the computer futher. If it has failed you could fry the components. I don't know if it has liquid cooling, but if so, be extremely careful.
A System Recovery is a very good idea. After updating Win 8.0 to 8.1 on my HP Split, I had several problems, such as, wireless connectivity. I did the Recovery back to Win 8.0. It solved my problems. After a few days I gave Win 8.1 another chance. It has performed admirably. If the system is overheating because the CPU fan failed this could cause your problems, also.

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..

Nokia 808 internet connection issue / limited conn...

Hi I have bought a Nokia 808 yesterday and the wifi connectivity has major issues.
When connected to wifi access point it is almost always followed by limited connectivity.
I can browse the internet using the browser but the following do not work:
Setting up new email - tries to connect and times out
Maps - Cannot download maps, stuck on 0 % - keeps telling me that im not connected
Weather - doesnt update, always says try again later
Nokia Sync - Thinks its not connected to the internet
Pretty much all internet based apps think im not connected
But as soon as I launch browser it works and opens all pages.
Also stores sometimes opens and says its not available in your country. I want to know why Nokia is selling a phone in my country with local nokia company guarantee and local language support on software and on packaging, but somehow does not give our country access to apps.
I have a Level One WBR6600 modem, never had issues connecting. Updated to latest firmware. All other devices work on the access point, only the nokia has problems.
I have reset countless times to original settings
Deleted access point / re added
I have tried changing access point security to WEP , WPA , WPA2 , and no security, made no difference
I think the problem is not my modem, but the phone. I have tried Tethering from my iphone to nokia and still very limited connectivity.
I have been using iphones for the past few years, and this phone was only appealing because of the camera, but I am very disapointed with the software of the phone. I feel like I downgraded phones. Right now without internet connectivity its a pretty strange phone.
Also very strange to see that the phone has a wiered VPN setup. Its impossible for me to setup my vpn accounts on it, it is asking me for some policies, i think it only supports corprate vpn access and not web serving vpns, like ALL OTHER phones do, with the easiest set up.
please help.

thanks emprazol, you are right, we are discussing this also here: http://discussions.nokia.com/t5/Connectivity/Nokia-808-Belle-FP1-bug-WLAN-works-but-not-all-apps-can...
