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

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.

Is it possible to activate an ipad w/o an internet connection on a mac?

Is it possible to activate an ipad without an internet connection on my mac?
I have got a macbook pro with iTunes 10.1.2 (17) and an micro-sim card with a iPad 3G data plan, so I can use it directly with the iPad, but I have to activate the iPad at first.
I have NOT any internet connection on the macbook pro (because I am actually traveling). So do not recommend to go to the next Apple Store etc.
Thank you.

You cannot get a wifi connection anywhere? (hotel, library, airport, coffee shop, etc.)
Yes, I can. But it costs $30 for 10 MB (minimal use) at the hotel. Just to compare: a 3G data plan with 3GB traffic costs $50 monthly

How do i get an internet connection from my Mac to my iPad using a usb cable?

I have a Mac connected to the internet through a modem. However, i also want my iPad to share this connection through the usb cable. Is this possible? If not, is there any other way i can get my iPad to share the internet connection from my Mac?

It look like you can turn your mac into a hotspot and connect your ipad to it via wifi.

Wireless Internet Connection Between a Mac Mini & a Notebook PC

A Mac Mini, A Notebook PC (OS: Windows XP Pro SP2), A LinkSYS Wireless-G Broadband Router (Model: WRT54G)
If the Mac Mini is connected to the cable moderm provided by the ISP through the router above. Can the Mac Mini share internet with the notebook PC? The Notebook PC has to be connected to the internet wirelessly.
Im wordering if it works or not as Im going to buy a Mac Mini.
If so...
What does the Mac Mini need?
What does the notebook PC need?
Im very new to MAC, I have looked through the discussion, but Im not sure if people's situation is the same as mine. Any help is much appreciated!

If the Mac Mini is connected to the cable moderm
provided by the ISP through the router above. Can the
Mac Mini share internet with the notebook PC?
The router in effect shares the internet connection to the Mac and the PC, neither computer needs to share the connection as they are clients connected to the router.
If so...
What does the Mac Mini need?
The Mac mini comes with an ethernet port which allows it to be connected to the router.
The new models now come with built in wireless so could connect to your wireless router wirelessly instead of by cable.
What does the notebook PC need?
If the Notebook PC comes with integrated wireless then nothing else is needed. If it doesn't then it will need a wifi certified 802.11g wireless card.

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

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.

Mac Mini Internet Connection Issues

In recent weeks the success of my Mac Mini being able to access the Internet and my home network is abissmal.
I have intermittant forced access at best, I have power cycled my router and modem from Time Warner. I have tested both WIFI and Eithernet to no avail
When I use the diagnostics it shows it is not connected, then it will repair connect and when I switch a page in my browser or go to use Skype, BOOM lost connection. This is occuring on both WI FI and Ethernet.
I have read in MAC Forums and on Google that other's have had similar issue.
Info I can add
LinkSys Wireless G router
Also have a WII console an iPhone and Android phone and MacBookPro sharing this connection.
It is nly in the last few weeks it has presented any troubles. I have done a spyware/malware virus check bought MacKeeper cleaned up all files. Short fo taking it in for service (I have only had it since early December)
Is in a router DNS issue, a MAC Mini Issue, a network issue. I am thinking I should have saved more cash and got an iMac.
Thanks

Using Airport Express as internet connection for one Mac and one PC

Will probably be judged a complete dork for this question. I have successfully set up my Imac G5 to run an internet connection through an Airport express. My partner runs a PC (Windows XP) and I want to connect this too. Have installed a USB wireless card on the PC, and installed Airport Utility, but it just won't find the Airport Express - it will however find the Imac with something like 96% signal strength. So I set up a network on the Mac and have successfully linked into it with the PC, but it soon comes up with a connectivity problem that will not allow internet browsing. So two questions - can I connect two computers to the Airport Express at once for internet browsing, or do I have to do it through linking the PC to a wireless network? If the latter is the route - any ideas on what the connectivity issue will be? Help!

No, not if the AirPort Express "joins" the wireless network.
No, I do not want to join a network.
It is possible to have the AirPort Express "create" a separate wireless network that would not have access to the Internet, but if you did this, you would need to log off of your normal network....(losing your Internet connection) and then log onto the AirPort Express network when you wanted to listen to AirPlay.
Then, when you wanted to have Internet access, you would have to log off of the AirPort Express network and log back onto your normal wireless network.
Ok, I understand that it is not possible to use airport express only for sound streaming while having an Internet connection at the same time. Airport express does need to join a network if I want sound streaming next an Internet connection. I wanted airport express not to get into way of my Internet connection because in this case the sound streaming messes up sometimes. When I configure airport express only as a sound output, the problems I encounter fade away but then I cannot access to the Internet. Anyhow thanks a lot for the answer.

Do I need Internet Connection to install Mac OS X Snow Leopard?

Hi,
I am going to install new mac os x snow leopard, but I don't have any internet connection at the moment and waiting for broadband service providers to provide me broadband.
I am just wondering that if I need internet connection to install this os or not?? should I wait for broadband connection or not??
any help will be appreciated.
Thanks.

*Some features require a compatible Internet service provider*
...which just means that you can't use Mail, for example, unless you've got internet service and an e-mail account. This has nothing to do with the installer.
Wait until you have a broadband internet connection. One of the setup guides needs to connect in order to set your time zone.
...which is not strictly necessary, since you can easily set it manually.
A more important issue is that, without an internet connection, the installer won't be able to check Apple's servers for an updated list of incompatible software. This is not strictly necessary, but it's a good idea.

WRT120N Internet Connection Issue

I have a unique problem that I have not been able to find any forum that helps. I hope someone out there can help me as I have been spending hours trying to fix it and gettin very frustrated. Linksys support blames the problem on my modem and my ISP support blames it in on the router. This message might be a little long, but I want to explain everything. I have had my router for a couple months now and everything was working fine. I use to have my router hard wired to my desktop and had another computer for my kids connected wirelessly. Just recently, I bought a new laptop to replace my desktop and was hoping to go completely wireless with my laptop and the kids computer. Before I tore down my desktop, I connected my laptop to my network and internet seamlessly so I could transfer some files. However, when I tore down my desktop and disconnected the ethernet cable that was hard wired to the router I lost my internet connection on all computers. The weird thing is as soon as I hard wired my router to my laptop I regained internet access and once I unplug it, I lose it. I have tried resetting my router and setting my network up for scratch again but it did not help. I have a feeling that is is some configuration setting on my router that needs to be changed, but I don't know what. When I do have my hard wire disconnected and I lose internet access, I can still access my network and talk between the computers. Please help!

That's understandable. I agree there's a doubt in upgrading the firmware because some had more trouble than resolving the issues. I checked the latest version for your router which is v1.0.04. However, most have it successful. I'm thinking that some wasn't able to upgrade the router properly, causing it to malfunction. And as to their technical support, they will still insist you to upgrade the firmware. There's no other way but to update it.
Anyway, I found your issue a little weird. But let's give it a try before flashing your router with the new firmware. Does your ISP rely on registered MAC address? Because some had trouble with it and cloning the MAC address resolves it. Here are the steps. Give it a try.

Can I use a airport express to get internet connection to a Mac Mini that doesn't have wireless by adding it to my existing wireless network?

I bought a first gen Mac Mini for our daughter and it doesn't have internal airport adapter and was wondering if I got a airport express can I plug it in my daughters room and use it as a local router and just use the eithernet connect from it. Or would a airport extreme work better for this job. I have a wireless cable modem that we connect to. I also have a second question I have a iMac G4 that picks up the wireless signal but will not connect to it does it have to be a Apple airport for it to work or should it be able to connect to any broadcasted signal. Thanks for the help.

I'm not sure I quite understand. Do you wish to use the AEX to provide a wireless connection for a device that has an Ethernet port but no wireless capability of its own? You wish to use it in place of a wireless card that isn't internally installed? If so, the answer is, "Yes." It will work as a wireless access point. But you must have an extant wireless network because the AEX won't have an Internet connection when used in this way.
If you have an existing wireless network with a wireless router connected to your cable/DSL model or your modem is a wireless router as well, then the AEX may connect to it in bridge mode. Note that AEXs don't always play nice with non-Apple routers. Some work; others don't.

Multiple Internet Connection Issues

Hi there, long time reader first time poster.
I figured I should post this as, while having read through hundreds of similar posts I still can't figure out how to solve my connectivity issues.
I just bought a new iMac 21.5 inch 3.2Ghz i3 model and while I am happy with the machine overall, it is the second one in a month - the first had a faulty ethernet port and refused to connect to the internet out of the box. Apple replaced it without question - almost as if they knew.
The replacement has now seemingly developed the same issue.
Some background info. The computer was connected both through ethernet and through the TC I bought to back it up until yesterday. So I was getting both a wireless signal from the TC and one through ethernet.
I have a hub that has 5 devices connected to it ( Printer, Cable TV, iMac and TC - now a PS3 ) That hub is served a signal by a simple NTT modem connected to a phone line. That modem is now nearly 5 years old but has always given great net speeds so I don't believe the problem to be the modem - I could be wrong though.
I just bought a PS3 and tried connecting it yesterday but had multiple problems. Despite me entering the correct PPPoE information to the letter, the PS3 refused to connect, saying the password and username was incorrect. I could connect it via a Bluetooth signal but no hard wired connection would work.
So I unplugged everything from the hub, shut down all the machines, turned off the modem and let it sit for 10 minutes and then plugged the ethernet cable from the PS3 straight into the modem, giving it a direct line. Switched on modem, rebooted PS3 and tried again - this time it connected through ethernet. I still don't know how or why. I can guess but I'm sure you guys know much more about this than I do.
So then I tried connecting the iMac back to the net, reconnected all the hub, followed the same procedure. Off, sit for a bit, on etc. This time the PS3 has no connection and now the iMac has no connection either!
The TC gave a green light though so I was able to get wireless. I tried removing all net locations from the iMac, installing new ones, renewed the DHCP lease, but no matter what I did (PPPoE info 100% correct) it just refused to establish a connection.
The the bloody TC light flashed amber and I couldn't get wireless either despite being plugged into the hub and getting a signal! The PS3 is now working and the cable is fine so I am starting to think either I have cluster ****** the whole setup or something is wrong with the iMac.
I go away for an hour then come back and the stupid TC has somehow picked up a connection! The light is green again?! But now the time connected display is scrolling repeatedly. I've got net but what the **** is wrong with all this?
Bottom line - not ethernet connection for the iMac but TC seems to be working and all other devices have a connection.
Please help me if you can! I just can't figure any of this out.

Your description is a bit confusing, but I use English as a second language, so it may be just me.
1. How is the hub connecting to your modem, by ethernet cable or wirelessly?
2. Which device is negotiating the internet connection with your ISP, the modem?
3. Does the device that negotiates the connection use PPPoE?
4. How are the other devices being handed their internet connection? DHCP only?
Only one device should be connecting directly to your ISP using the PPPoE protocol and configured with your account username and password. This device is preferably the modem. This device should be configured to hand out internal IP addresses to the other devices on your LAN using DHCP. All of the other devices should be configured to request an IP from that device, whether by ethernet or wi-fi, just with DHCP.
