Internet stops working frequently on OS X Lion

I had 10.6.X latesr version was OS X and I was happy with that. Now I have upgraded to this Lion OS and I am getting one very embarrasing issue.
Internet stops working frequently. The following will give you the feel of the issue:
- I am starting safari and will browse for sometime.
- Suddenly I wont be able to open any sites, internet will stop working.
- So I check wifi, it is online and showing correctly in my Mac Book Pro.
- I checked with my room mate his internet is working properly.
- I changed browser I am not able to browse site in Chrome too.
Solution restart MBP or on/off wifi and restart browser then internet will start working. I am fed up of this lion problem. Does any experienced this problem? Is this a bug? Why I upgraded to this Lion?

I am facing the same issue, only with a slight difference. My entire system sort of hits a halt, apps still work, but they refuse to close.
I am using Internet Sharing to share my internet connection from my iMac's Ethernet port to the WiFi. After a while, not only the iMac's internet stops working, the internet sharing stops working too, not to my surprise. Restarting the computer seems to solve the problem but not 100% of the time, and everytime I try to restart the system, all my open apps seem to refuse to close and I have to either force quit them, which works sometimes, or do a force shutdown by holding the power button for a few seconds.
Making the Ethernet port inactive and reactivating it does not solve the problem, nor does disconnecting the ethernet cable and reconnecting it.
I have a little software installed that monitors my network activity and displays it in the menu bar. I have it currently monitoring my Ethernet port and what happens when the internet connection stops working is that the Ethernet port, although still connected and with a green light, just stops sending and receiving data, sometimes it does receive some data but it stays at 30-60 B/s.
I'm sure this is an issue with OS X Lion because I had never had this issue with Snow Leopard until I upgraded to Lion.
Realy hoping for some guidance from Apple here on how to tackle this issue, it's quite annoying to have to restart my iMac all the time. I am used to leaving my iMac on all the time cause I access it remotely often using LogMeIn on my iPad. As well as that, I have other network services running and it's quite annoying to try and access my iMac remotely and find out it is offline because Lion refuses to keep me connected to the internet.

Hi，
So switch a LAN card fix this issue...seems a compatibility issue or maybe some packs or programs you installed recently cause this issue.
Have you manually check the network adapter driver from the PC's manufacture website? sometimes, it will be a time delay before Microsoft push out the driver update.
Check if issue exists in safemode with network, this mode will launch Windows with limited sets of files and drivers.
if you have a restore point, restore the pc to a previous point at which the pc is functioning fine.

Internet stopped working on MBA after latest firmware update. Help please!!!

Internet stopped working after installing the latest firmware update. WiFi still connects to router, our other mac desktop still connects to internet as usual (same network). I can't even re-install the MBA OS since it needs an internet connection!!!
Any ideas?

FIXED.
I swapped our wireless router for a newer one, internet seems to work fine again (we were sent a new one by our internet provider which we never set up until now).

After like 10 minutes internet stops working

okay so this all started when i updated to dp 3 or something, then the internet started acting up.....no matter if i update or not (this has been going on for like a month, and i'm on the actual release of yosemite) it keeps on doing this stuff where the internet stops working.....it seems like the less plugins the better because when I use browsers such as "Netsurf" or "Opera" the internet works for like 15 minutes, but then for safari, its like 2 minutes and stops working. In order to get back online I have to completely log off and log back on, so thats the real problem, especially because I have to use the laptop for school. I currently tried to find the issue by having the console open on the side so when it finally says "0 B" on opera, I could check the error. What appeared when this happened was this:
10/23/14 12:31:27.037 PM Console[789]: Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable
So, great I found what the issue is, but now what I need to know is what can I do to fix this? Please I'm desperate, because not only is this my laptop but it's my mom's. So she has like an entire buisness set up, and due to this error....it's screwing around with her timing on getting everything in for her buisness. Best regards,
Tom Hancock

Slightly different issue but maybe it will help someone solve the OP problem. Just installed 10.10 and using Safari.
This is my error message...
28/10/2014 12:41:14.757 pm Console[7383]: Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable
I get this whenever I try and reply to an email in OWA (Outlook Web Access). It causes Safari to crash. Up to this point the internet is accessible without problems.

Lumia 520 - Internet stops working sometimes. Nee...

I have been using a Nokia Lumia 520 for 6 months. Sometimes the internet stops working. Only after removing and replacing the battery, the problem is resolved. It happens say 2 or 3 times a month. Is this a common problem? Does it indicate a problem with the hardware or software?
Thanks
Solved!
Go to Solution.

Switching the phone off doesn't really switch it all the way off, it just puts it into a kind of "sleep" mode, but the O/S is still running. How would it know that you've pressed the power switch otherwise? Even if it's interrupt-driven rather than the switch being polled constantly, the CPU still has to be running to register the interrupt (see http://en.wikipedia.org/wiki/Interrupt for a description of what an interrupt is).
By pulling the battery out you're forcing the phone to shut down completely. There's no way it can continue to run without power.

Internet stops working every time I try to download anything from iTunes.

Every time I try to download a movie from my purchased list on iTunes it freezes shortly after stating then the internet stops working. This only happens on my iMac. I have 10.10 and everything is up to date on my iTunes. The internet is not affected on any other platform. To regain internet I have to disconnect from wifi and reconnect.
On a side note, sometimes when I restart my mac the finder bar disappears and the system freezes. I have to hard reboot and then soft reboot for it to work properly again. Help please!!

Maybe I owe itunes from a past purchase? I'm guessing maybe there was not enough money in my bank account the last time I purchased a song. But now there is. My debit card info is correct and there is plenty of money in the bank account.

Internet stops working after being connected for 5 minutes to wifi

My macbook pro running on os x mavericks is giving me an issue. After 5 minutes of connection with the wifi network, the internet stops working even though its connected the network. Reconnecting fixes it for yet another 5 minutes.

Might be corrupted network preferences ..
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.
If that doesn't help, try here > Wi-Fi: How to troubleshoot Wi-Fi connectivity

Internet stops working at random

Hi Guys!
This is about my girlfriend's MacBook.
We have a LevelOne WiFi router, works perfectly fine for my MacBook Pro and other computers (Windows XP, Vista,...).
She can connect to the Wifi and use the Internet. However, after a while - the duration changes, sometimes it's only a few minutes, sometimes it lasts for 30 min. - the Internet stops working.
The MacBook still has full WiFi connection but she doesn't have Internet (no websites, no skype, etc). It's not dependent on what she's doing, sometimes it happens even when she doesn't use the computer.
In the Network Preferences it says that "AirPort has a self-assigned IP address and may not be able to connect to the Internet." Under TCP/IP it's set for using DCHP and also shows an IP and a Subnet Mask, however, the field for "Router" is empty. Renewing the DHCP lease doesn't help, she has to disconnect the Wifi and re-connect, then it works again.
When it works it says that it has another IP address (192.168.123.167), Subnet mask is 255.255.255.0 and Router is: 192.168.123.254
You can probably imagine that this is annoying like sh*. Help us before I have to bring her to the asylum

The Internet stops working because you are either losing your association to the Wi-Fi router or your DHCP lease is expiring.
The first step to take in debugging this is to make sure your Wi-Fi router has the most up-to-date firmware available from its manufacturer installed on it.

Notifyd using 70% cpu, webfilterproxyd 48%, and syslogd 18.4% and internet stops working

This happens almost everytime I am online. The fan gets super loud, the internet stops working (connectivity is great but no pages will load, regardless of browser). Sometimes turning off the wifi and turning it back on allows me to use the internet for another 30 before the problem happens again. The only way to get the internet to start working again is to restart my computer.
Whenver the problem happens I find the above processes taking up all the CPU. All 3 are root processes.
This started happening about a year after I got my macbook pro brand new. I have been dealing with this forever. Have searched online everywhere over the course of months and cannot figure out the problem.
PLEASE HELP! It is so annoying having to keep restarting my computer all of the time!!
(note: I haven't updated my mac to any new software since getting it. Didn't realize I could until I saw the new Maverick update. So my macbook pro is still OS X 10.7.5 just like when I bought it.)

just saw another post...is this possible an issue with having parental controls on this account?

Internet stops working after waking up from sleep

My MPB has a strange and very inconvenient problem. Sometimes when it goes out of sleep Internet stops working. No matter what connection I use: Ethernet or WiFi (tried both), no site can be opened. The strange thing is:
at the same time other devices connected to the same router work fine (both wired and wireless), so router and ISP are OK.
from Mac I can ping any site by IP (and Skype works fine too).
So it looks like some service in Mac OS that is responsible for domain name resolution stops working.
What I tried:
Restart router - no effect
Move Mac to sleep and wake again - no effect
Restart Mac - the only cure. But in this case I have to close and open numerous applications that is really bothering.
Should I mention that all updates are in place?

Try this. Go to: System Preferences/Network/Advanced/ and click on the far right part of the bar, PPP. You have seven possible items to be clicked: instead, only click "Connect Automatically..." and "Disconnect when..." - and leave everything else unclicked.
That should solve your problem, though it'd be great if you were to post your results here.

Internet stops working on new wrt56gs router

Greetings Helpful,
I recently installed a new Linksys WRT56GS router on my work network, but it drops the internet connection from time to time. Unplugging the router fixes the issue temporarily, but I would love a more permanent fix.
Here are some other details:
When the internet goes stops working, the radio station I stream does not get affected (it continues to play)
The interruption of internet service seems more frequent with more users on the network (example fine all wekend, but down within a few minutes of the lab filling up)
The firmware was updated (7.50.2) after the router was configured
I checked the settings with the ISP
In 5 days, since Thursday, it has probably been down 6 times
Thank you for your time and consideration.
All the Best,
Charles

Change the MTU size from 1500 to 1450 ...under setup tab ..... clcik save settings ....
Uncheck block WAN request .... under security tab ......click save settings
Under advance wireless settings .... change beacon interval to 75
rts & fragmentation threshold to 2306 .....

Internet stopped working on Windows side

For some reason my internet connection just stopped working on the Windows side of my MBP. Last week I was using it, and one minute it worked, the next it didn't. I didn't make any changes to settings, etc.... Not only does it not work with my wireless setup (1TB Time Capsule), but I also tried plugging directly into my modem, which didn't work.
Internet is working fine on the Mac side of the computer.
I'm kind of in a jam... I need to use Internet Explorer to run my payroll software (That's about the only thing I use it for), so any help will be appreciated. Otherwise, nobody will get paid next week... lol.
FYI... I use VMWare Fusion to run Windows XP.

Never mind... It started working again after I messed with some of the DNS/IP settings. I don't really know what I did to make it work, but it does.
