Losing internet connection after starting some apps

Hi all,
I'm having this problem with my arch linux install (I've been having this since the beginning and have reinstalled arch about 4 times for other reasons). I'm having the problem when using both wicd or netcfg to connect and both with wireless and wired.
When I'm connected to the internet (and the wireless router) and I start rtcw (return to castle wolfenstein) and go to serverlist it hangs for 30 secs and than says trying to connect to master server. When I go back to the desktop I have no internet at all and can't restart the connection or anything everything just hangs and my wireless card suddenly can't even detect the router (not even when I'm sitting next to it). The same problem happens when I start crossover pro / games. The internet suddenly stops working and by consequence I can't download steam to install, etc.
Does anyone have the same problem or knows a solution?
If this problem gets fixed I will donate 10 euro's to the arch linux project because besides this everything works!
thx in advance,
Ruben
Oh and all this software was legally purchased if you were wondering ;-). (student discount woohoo)

yeah tried that , didn't work. (already tried it before you gave this tip ;-))
Got some more info: I think it's a firewall/ router issue because when my internet falls out by starting the programs (and checking serverlist with games) then for everyone in the house the internet stops . This must mean that somehow what my apps want to connect to isn't allowed or something and the firewall or router stops the internet. I know it sounds strange but what other explanation is there?
my setup at home:
apple airport router +
apple airtport router with storage (don't know the official name) +
linksys router (this one is because my linux laptop can't connect to the apple crap even if the apple routers emit on b and g channels)
A lot of routers I know but my dad set it up.
Does arch linux (or linux in general bcause had these problems also on other distro's) use other ports for games serverlists and apps (like crossover) connecting to internet than windows? Strangely when I use my desktop (with windows xp installed) booted with slax usb I can connect and play rtcw online no problem so there must be a problem in my setup.
other ideas?

Losing internet connection after Flash Player update.

Recently, I suffered from a Fake Flash Player infection involving the Adobooaan hijacker malware. I had great difficulty getting rid of it and in the end resorted to using Spyhunter and then hand-deleting the things it came up with.
[Yes, I know Spyhunter is semi-malware itself, eats cpu space and and keeps popping up every half hour demanding payment, but I have it on a leash. I used AVG PC Tuner to set Spyhunter so it runs only when specifically told to, and then switches off when I've finished with it.]
Using Spyhunter in this way got rid of the Fake Flash Player hijacker when MalwareBytes, Spybot and Adware-Removal-Tool had all failed, but one of the side effects was that I had to re-nstall, or at least partially re-install, the real Flash Player. Now, I keep losing my internet connection, and it appears to be happening when I get a "The Adobe Flash Player Update Service service entered the stopped state." system event.
The outage affects all browsers, and only access to web pages online. I can still get emails, and open web-pages which are on my own PC, but I lose access to all online pages. The only cure for it seems to be to re-boot my router by switching it off for a minute, yet my PC's connection to the router seems to be sound, and my ISP's tech team say the router looks fine from their end.
Spyhunter is a bit over-enthusiastic - it identified a legitimate TextBridge file as a malware of the same name, e.g., so I'm wondering whether in removing the Fake Flash Player infection I've accidentally deleted some legitimate Adobe Flash Player file or cookie, causing Flash Player to switch off my internet connection at the end of every update check. But if so, how do I fix it? Is there some way of getting into Flash Player to set options? It doiesn't seem to have an icon or to appear in the programs list as something you can get at and twiddle with.

Yep, I've got the exact same problem. I'm using a PowerMac G4, running 10.4.5 (I think). I can't say the problem started happening, since I just started using the sleep function (computer generates a lot of heat in my apartment in the summertime!).
But yea, I sleep it using the HW button, and bring it back, and no internet connection. I'm not sure if it's the computer (SW caused) or the ISP (disconnects if the computer doesn't respond to pinging). I am using Comcast cable Internet, which is DHCP me thinks.

A7-50 3500-F losing internet connection after 10 minutes.

Hi everyone, My A7-50 A3500-F seems to be having some problems maintaining internet connection. After around 10 minutes chrome tells me I'm offline, youtube can't load anything and messenger stops working as well. Disconnecting and connecting again fixes the problem but it repeats over and over again. I mostly use it connected to my home wifi, which I know works fine. I tried connecting to other networks and the same thing happens It happens. I tried soft resets, hard resets and restoring it to factory settings but none of that worked. The tablet is running on android 4.4.2. Any ideas on how to fix that? I just got the thing and I don't want to RMA it and lose it for a month.

End result that should fix it (hopefully) Returned it to Harvey Norman for their tech team to look at it.... Lenovo advised them to hold the tablet for a couple of weeks because they were waiting for the parts needed to repair the problem.... at that point Lenovo hadn't even seen the device and the tech team at Harvey Norman had no idea what the cause was..... 6 weeks later, after being chased by the team at Harvey Norman (who still have my tablet sitting on their work bench) Lenovo says they still don't have the parts and due to the delay will issue a replacement device.... That was three weeks ago.... Still no tablet and no word as to WHEN the replacement will be issued.... Fingers crossed it gets upgraded to a refund so I can buy something that works

HT1218 Airport Time Capsule losing internet connection after 3 hours

I just got a Time Capsule and my internet connection seems to time out after 3 hours or so. My macbook/iphones/ipad seem to still connect to the internet but there is no internet connection. The only fix seems to be unplugging the modem every 3 hours. I think I have the most updated systems on everything. Does anyone know what I need to do?

Hi there Tharv23,
You may want to reset your base station to factory settings as an inital troubleshooting step. Take a look at the article below for more information.

WRT54GL: Losing Internet Connection after shutting down computers

I've got a Linksys wireless router, the WRT54GL.
When we set up the router and connect to the internet everything works fine. But when we shut down our wired computers and restart the laptop, the internet connection is gone, but I keep my local area connection. I already have done a firmware upgrade (v4.30)
Our configuration is as following: A Zyxel Multi-user PC modem, straight cable from normal interface to the WAN interface of the linksys router. Our (2) computers are connected by cable to the router, while we use the laptop for wireless connection.
Any suggestions to fix this problem?
Jeroen

Open routers set up page using http://192.168.1.1 ..... leave username blank & in password use admin ....
Click wireless tab..... use any non-linksys network name (SSID) ..... use channel either 1 or 11 ..... click save settings .....
Click wireless security subtab .... use security level either WEP or WPA ....... have a note of the key ....
On laptop try to connect to network ....... or configure the wireless utility (if you are using WLAN) ..... see if it makes any difference or not ....

Losing internet connection after sleeping

I have an iMac - about 2 months old & airport extreme which I purchased at the same time. My provider is Time Warner Cable's Roadrunner service.
Every time my mac goes to sleep, reconnecting to the internet is murder. The green light remains on, on the AE. If I go to system Preferences > Network it tells me that Airport is connected to the Apple Network etc & that VPN is cnfigured, but not connected.
I have found a fix, but it's hardly hassle-free - I change the location and apply. That usually works. Next time it happens - and this can be anything from being away over night to 15 mins - I just change to another location & eventually get back on. It's really frustrating.
When I go to Show > AirPort, my settings are:
By default join preferred networks
PPoE isn't checked
Am I making really basic errors?

Well that worked for a while & now it's worse than ever. I have to play around with the settings for about 5 mins before it miraculously finds the internet again, but without me having actually changed anything. I just change the location, change it back - repeat a few times - and then it works.
It's extremely frustrating

No connection after starting or restarting the system

Hi,
I have a problem.
There is no internet connection after start or restart.
Until last week there had been no problems. There was an automatic connection with my SPEEDTOUCH9FF4D8.
But suddenly it does not connect automaticly. I can select SPEEDTOUCH manualy and than it works...
Thank you for your answers.
Mac Book Mac OS X (10.4.10)

Hi im slightly confused by your post whether its the computer not connecting to the network automatically or whether there is no internet connection to the router at all but heres a few things to try anyway!
First of all, if the internet goes down and restarting the router doesn't solve, then unplug your cable modem for at least 5 mins, the cable modem needs to forget the MAC address of the previously plugged in device. Then start it up and when the ready lights are on the router (or about a minute after starting the router) then plug in the router and the connection should work!
Secondly, if your computer doesn't automatically connect to the network anymore (presumably your on mac osx) then go to System Preferences / Network then select configure AirPort. Make sure 'By Default, join' is Automatic, then go to options at the bottom and select 'Automatically Join and Open Network'
Hope this helps!

IMac keeps on loosing internet connection after a few minutes...

Intel dual core iMac with 10.6.8 OS keeps losing internet connection after a few minutes. Need to put it to sleep and bring it up again. Than it works again...for a few minutes. Other equipment like laptops and iPad using same wifi internet connection and have no connectivity problem at all... What to do?

Then what I suggest that you do is go to the Finder and select Mac Help in the Help menu. In Mac Help go to Index>C>Connect to the Internet. There you can read all about configuring your Mac, using a modem, etc. After you better understand how all that works then come back with your questions.

My iMac keeps on losing internet connection. Webpages get stuck after a minute or so. If I check the internet connection via diagnostics it seems to work just fine. Others, like the iPad use the same wifi connection and never fail. What can I do?

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

My MacBook Air which is only 3 months old, keeps on losing internet connection. To reconnect I have to click on the internet icon on the top bar and click turn wi-fi off. I then have to click turn wi-fi on and it reconnects after a few seconds.

My MacBook Air which is only just over 3 months old, keeps on losing internet connection.. To resolve it I have to click on the internet icon at the top of the page and then click turn wi-fi off. I then click turn wi-fi on and it reconnects. This resolves it for a while, and then it disconnects and I have to go through the same procedure again. My BT Home hub is fine because my wife's i pad and our phones are all ok. What can the problem be?

Hello Cambusnethan5,
Thanks for using Apple Support Communities.

Losing internet connection with youtube in safari

I keep losing Network connection after i use YouTube in safari. Need to restart iPad to get connection again. Anyone an solution? I Re installed already 2 times but without any luck.

Use the you tube app that came with the pad, and see if the problem happens there are well.
Do you internet on other apps or browsing? I think you have an internet issue, not a you tube issue.

Why is my macbook pro running so slow and losing internet connection?

Why is my Macbook Pro downloading so slowly and losing internet connection frequently?

Write off the MS stuff as indicators for now--starting with Office 2008, they developed very long launch times. The time to launch 2008 on my old 1.25Ghz G4 and my MBP 2.2G are virtually the same. Even document opens/saves are slow compared to Office 2004 and earlier.
1) You have adequate hard drive space so that eliminates one of the usual suspects.
2) Check for runaway background processes. Quit all running user applications so the computer is at normal idle. Find Activity Monitor in Applications > Utilities and launch it. If you've not run it before, change the "Show" pulldown at the top of the AM window from its default of "User Processes" to "All Processes." There is a column for "%CPU." Click that column header to sort by CPU usage. Watch the processes "bubble" for about a minute to get a better picture of the usage.
If any process is using more than about 25 percent of the CPU cycles while the computer is idling, post the names of the processes and we can see if they can be eliminated. My MBP shows nothing using more that about 5 percent on any given test run as long as I close all my user apps.
3) If you have never done any sort of maintenance procedures, taht can slow you down. Simply restarting the computer a few times a week clear a lot of temporary files. You also may wish to review this article on the Mac OSX periodic maintenance scripts, which, if run, also do a lot of cleanup:
http://thexlab.com/faqs/maintscripts.html
There are other useful articles on file maintenance associated with the one. Here's the index:
http://thexlab.com/faqs/faqs.html
Check out articles with "Maintain" and "Tuning" in the titles.
4) Use Disk Utility to check the SMART Status of your hard drive. A failing drive can make things slow before it makes things stop.

Lost internet connection after installing BT dongle (MS-6967)

I have tried installing the MSI Bluetooth USB dongle (MS-6967) drivers twice. I tried the 1.3.1 version and the 1.4.2 version drivers. The Bluetooth dongle itself works fine, but both times I lost my internet connection after installation. After this I have to remove the drivers and repair my installation with the Windows CD, but then windows and all of my programs also need to be updated again since my original Windows CD is a first release version.
The weird thing is that I can connect to other local computers and I can even ping external computers, but browsing websites (on IP address), looking up domain names and retrieving mail are no longer possible. I have no firewall software installed.
Does anyone konw how to fix this?

Am I really the only one with this problem? Well I have seen someone else on another forum ...
Maybe someone knows how to reinstall just the TCP/IP stack?
I'm using a notebook with buil-in network card. It runs W2K dutch version SP4 and things worked before when I was using SP1. Somehow it doesn;t work now anymore. Before I start reinstalling everyting again, I just want to check once more if anyone has some tips for recovering.

Apple programs will not recognize Internet connection after Tiger upgrade

In January, I posted the question below. I wanted to update it, but this site has archived it and will not allow responses. In the hope that I may help someone else, I am repeating my question, now that I have the answer.
===============================================
ORIGINAL PROBLEM
Last week, I upgraded from 10.3.9 to Tiger. Ever since then, I have had trouble using Apple's programs that require internet usage: Safari, iTunes, Software Update, etc. All of these programs think I am not connected to the Internet. But I am; I can use Netscape, Internet Explorer, and other non-Apple programs on the web.
Furthermore, it's not consistent. Sometimes Safari will recognize the connection. I'll be using Safari, looking up websites, when suddenly it will quit connecting, giving me the message, "Cannot connect to the server," no matter what server it is, even apple.com (so I have to use Netscape to access my .Mac and this Support screen).
How can I resolve this?
==============================================
The problem was that my Earthlink Access software was setting a proxy on my connection. Netscape & Firefox worked because they ignore any proxies; the Apple programs (plus Shiira and Internet Explorer) didn't connect because they use the proxies.
Why did it sometimes work? Well, if I first used Safari to go to a secure website of my bank, somehow that opened up the connection and then I could continue to use the Internet and Internet based programs like iTunes and widgets. However, if I tried to use an Internet-based program before going to the secure site, then it wouldn't work.
After months of phone calls and e-mails and sending data packets and all such stuff with Apple Care, they finally stumbled upon this answer: Uncheck the proxy box. And that did it. At first I had to uncheck it every time I started up the computer, but now it stays unchecked and I can use my Apple programs with no trouble.
I just wanted to share this with you in case you also had trouble with Internet connections after upgrading to Tiger, because I did see several other people had this same trouble.
Movable flat-screen iMac G4 Mac OS X (10.4.6) 1.25Ghz processor, 256 MB memory (DDR SDRAM)

For the record, could you state each Proxy box you ended up unchecking please? I'll attempt to submit a user tip with credit to you for finding this solution.

MBA loses internet connection after waking from sleep

I have a new Macbook Air running Mavericks and new 802.11ac Airport Extreme router.
My problem is that the MBA drops the internet connection after waking from sleep. I tried the solution offered by the OP, but it didn't work.
In my case, here's what I have to do to get a connection again. I open the Network preference pane, and then choose "Assist me..." and then "Diagnostics". Invariably it will show a green light beside Wi-Fi, Wi-Fi Settings and Network Settings. I have 5 bars showing in the WiFi menu bar icon. But ISP, Internet and Server will be yellow.
When I go through the steps prompted by the wizard, the ISP/Internet/Server lights turn green on the third screen where I select the wireless network I want to join.
It seems as if it's connecting to the WiFi network when it wakes from sleep, but losing the internet connection?
Note: I have a new iMac as well running Mavericks and don't have this problem with it.

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.
