WiFi Internet connection lost after iMac wakes up, what to do ?

Hi,
I used my iMac for a while with an older D-link product and Internet connection was fine. I purchased a new D-link product and whenever my iMac goes to sleep and wakes up again, I lose INternet connection although my airport icon still recognizes the network and says signal is at full strength. Apple Care can't help me.
I have a PC directly connected via wire to the same router and Internet connection is flawless so my ISP is not the problem. I use cable modem.
No it got worse. I start up my Mac, have connection but if I stay to long at the same webpage and then try another page, somehow it stalls!! Very frustrating. Anyone any ideas ?
Thx&Rgds

To Apple Discussions!
"I purchased a new D-link product"
Have you contacted the manufacturer to determine if the problem is with them?

Wireless Internet connectivity lost after sleep

I've got a problem where I keep losing my wireless network connection after going to sleep.
The situation is that I'm connecting to my university's secure network. I have the credentials saved on my MacBook. When I need to go and leave my computer on my desk, I go back to the login window, and close the lid. When I come back and open it again, I'm instantly asked for the network password, at the login screen. Regardless of whether I enter it or dismiss the dialog, I'm unable to get a connection automatically after I resume my user session. There's an exclamation mark on the network icon and it says that there's no internet connection on the menu. When I click on this warning, I'm asked to repair the network connection and re-connect to it. This works, but I'd much rather that this be done automatically. Is there no way for me to resume connectivity after waking up my MacBook without having to manually re-connect?
Thanks in advance for any suggestions.

The problem's still happening in 10.6.2. I lose my Internet connection when I go back to the login window, then close the lid on my MacBook so that it goes to sleep. When I awake it, and log back in, I'm shown as being connected to the network, but not to the Internet. I have to manually re-connect.
When I just close the lid without exiting to the login window, it appears that my Internet connection is re-established automatically, though, on re-awakening. I'm puzzled as to why this is occurring. It looks like a bug to me.

Internet connection lost after browsing the internet

Hi, I am fairly new to the mac world. (less than two years) And I have a problem that I was hoping someone can help me with.
I have a Power mac G5 dual processor, with Mac osx panther installed. Everything works great, except when I try to browse the internet. For some strange reason it will drop my connection and to bootm I also have a G5 server that I am connected to, but as soon as I lose my internet connection I also lose my connection to my server. Now I know it can't be the router since other computers keep their connection while mine drops randomly.
Our office has a basic setup, computers and server plugged into a switch, the switch goes to the 2wire (router/DSL combo) device. The firewall is within the 2wire and the server's and computers' firewall are disabled, since the 2wire has the firewall protection the whole subnet.
Please help
Thank you
G5 Server Mac OS X (10.3.9)

I had this same issue on an Acer Aspire 5520 laptop with an atheros chipset for which I was using ndiswrapper. Long story short I downgraded to kernel 2.6.24 and that fixed the problem .
Sorry not much help...I have no idea where the culprit is, but it is a very annoying problem.

Internet connection lost after -Suy

I just went through a huge -Suy and I've lost the ability to connect to the internet.
I have had problems with my router lately (I've been having to restart it almost everyday to start dhcp on my pc's). However, I restarted it aobut 12 times this morning, and I can reach the internet on my webserver which wasn't upgraded recently.
The only major package upgrade that might be relevant that I can remember is udev.
I'm using the forcedeth module for networking, and I am getting a message in my 'everything.log' that says something to the effect of
Timed out while waiting for a response from a valid DHCP server.

Actually it's working just fine. For the first time ever udev has made a distinction between my two networking cards, and named my onboard networking card eth1. I changed it to use eth1 in rc.conf and now i get this
[root@sg01 sgillespie]# /etc/rc.d/network restart

Internet connection lost after machine sleeps or idle for a while

I upgraded my 24" iMac, 2.16 to a 27" iMac I7. I am now having probles remaining connected to the internet after the machine is idle for a while. I am using a Time Capsule and cable router and have been using the same two devices before the ungrade in my computer. I am also using OpenDNS, again as before. My computer is wired to the TC via ethernet and my wife's computer is wireless. She has no problem. She does not lose connectivity at all on her iMac 24". The drop occurrs time to time after the machine sleeps or sits idle for a while. I know Ive seen various threads about connectivity issues but can't seem to find an answer. Help is appreciated.

I had a very similar problem which I fixed like this:
1) Move the file /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist to your Desktop.
2) Reboot
Snow Leopard will rebuild this file from other info.
This sorted out all my won't connect/loses connection issues.

IMac can't connect to internet dial up after start up.

I've a problem every time I try to make a connection to the internet directly after starting up my iMac. The very first time I try to log on to my ISP the Mac appears to make a connection, the status window in Internet connect indicates that it has (generally 52-54000bps), but when I try to surf, my browser can't find any sites, same with email. I get the standard connection noise when dialing out, occasionally the noise drops out mid way through, but it always makes a connection. Sometimes it will disconnect after about 30-40 secs, sometimes it doesn't. When I reconnect a second time I get good speeds and can stay on for hours. This is happening every time I boot up and dial out, basically I now expect to have to dial out twice before I can get onto the web every time I switch on the computer.
I've read a few threads re this problem, it seems the iMac has a software modem which can cause some problems, but there doesn't seem to be too many complaints about this exact same issue. Should I be getting a Mac tech to sort this out or is this a generic issue that may be resolved in a future software update? This is a new Mac my second as the first nearly flew out the window after a kernel panic. Apple tech support in Sydney don't seem to have heard of this problem, and have told me to re install the OS again, which of course I have, plus run disk aid and re set the permissions etc etc...
The ISP has given me an alternative dial up number which actually works the first time I dial in, but I only get speeds of 28000bps. Can anyone shed any light on this? Will I get a similar problem if I went to Broadband?
Thanks for any comments...

Unfortunately I've not got any help on this issue. An Apple tech has told me to try changing the modem settings down to V34 which I did, the connection worked correctly but I was only getting speeds of up to 33000bps, real speed tests showed I was actually only on 28000bps, same as when I dialed the alternative number given by the ISP, not good enough. I don't have any other devices connected to the phone line, in fact the line is only used for the internet. Maybe there is a problem with this type of software modem, but then why isn't there more comments here, unless everyone else is on broadband. Apple and my ISP seem to think the slower connection is more reliable, it is but at a cost. Not sure why this is considered better when the speed is so slowww. Like Seb above I don't have any problems when I'm using a Windows lap top on the same line.
Anyone out there know the answer??? There are at least 3 of us with this problem...

Internet connection lost when restarting the computer

Hello everyone.
I live in Denmark, and 6 days ago I bought a new TOSHIBA pc: a Sattelite L855D-100. From the very start there has been a problem with the wireless internet connection. When I restart the pc, the internet connection is gone afterwards, and I am not able to re-establish the connection in any possible way. I have to shut down the pc - wait a few seconds - and then start the pc in 'normal' way. Then the wireless internet connection is okay.
But the problem is the same every time I restart the pc.
Does anyone know how to solve this problem?
I thank You in advance for Your help and advice.
Best regards Svend in Copenhagen.

Satellite L855D-100 (PSKAYE-003004DU) <- Netherlands version
A brand new computer should work right off the shelf, Svend.
I would restore the hard disk to its original out-of-the-box contents using Toshiba recovery media just once. And then return it for a new one if things are still not working right.
See the section System Recovery, which begins on p. 4-16 of the User's Manual (attached).

JCoRfcProvider: connection lost after a while

I have created a couple of EJBs and propagated them using JCoRfcProvider to an ABAP system, so that the backend can reach them. But after a while the backend looses the connection to the JCO server process: "program XXX not registered". After a restart of the RFC destination using Visual Admin everything is fine again. It seems that the connection between the systems is closed when it is idle for some time.
The <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/2c/760e4248fc5133e10000000a155106/frameset.htm">documentation</a> says:
If an RFC connection is interrupted or terminated, the JCo server automatically
registers itself again on the same SAP gateway under the same program ID.
Obviously, this automatic restart is not working, as the connection stays disabled once it has failed.
Is there a parameter I missed? Is this a JCO bug? How can I get this thing stable?
Best regards,
Frank

Hi all,
Lets start off with some info. I have a XP machine with a WRT310N router but the connection to the router from my computer is wired. I have other computers on the network(a wired XP work comp and a wireless vista laptop). I do have linksys Easylink Adviser but it is was to laggy and doesnt work half the time so I dont use it. My antivirus software is Panda Internet Security 2008.
My problem has only occurred twice but it has prevented me from trying to make a server again. I have been wanting to host a dedicated counter strike source server in steam for awhile.
I followed all the port forwarding directions. I get the static ip set up and I open the 27015 port for steam.
I will make a dedicated server and have a few people join and then I follow. Everything works perfectly for about 5 minutes and then my friends are dropped from the server due to loss of connection. I am still in the server but no one can join or even get info on it meaning the server is not responding.
I then close out of steam and the server and find I have lost my internet connection. I can not visit any websites, I can not do anything in steam, I cant log onto aim, xfire or anything.
Now my local connections dont say "Connection lost" like they do when the router is shut off or if I lose the actual connection.
The only way it seems I can get my connection back is by unplugging the router, waiting 20s and plugging it back in. Then I have to wait about 5 more mins and it will just all of a sudden work.
Does anyone have an idea of what is happening? Is it the router? My antivirus/firewall?
Thanks in advance
Greg

Connection Lost After Wake From Sleep

I am using a Macbook Pro and Linksys WRT150N W/L router. Every time my MBP wakes from sleep, I lose my internet connection. My menu bar still shows that I'm connected to the network, but I lose all connectivity. I cannot connect to internet or my router settings unless I do a complete restart. Network preferences shows connected to network but no connection to my router IP address under TCP/IP tab in the advanced settings. I also have a drop out of signal a few times an hour. My iMac DV does not experience the drop outs or connection loss at anytime. I have reset my router numerous times and used default factory settings all with the same results. Does anyone have an idea what the problem may be? Thanks.

I was always experiencing drop outs as far as what my signal was showing in my menu bar. It would drop out even if I was on top of my router. I had upgraded to 10.4.11 and the day after I did that, the problems started. I thought I might as well upgrade to 10.5 to see if that might help it. I think the 10.4.11 had done something to my W/L card and upgrading to 10.5 wouldn't have helped it unless I upgraded from 10.4.10 to 10.5, skipping 10.4.11 all together. I'm gonna bring my router and MBP into the genius bar and see what they can tell me about. Thanks for replying. I'm glad and sad to hear that I'm not the only one experiencing these symptoms.

Internet connection lost with wired connection in hotel

I am in a NYC Hotel and was able to get an Internet connection on my MacBook (2 ghz intel core duo running 10.5.8) via the wifi network with extremely slow connection speed. They also offer Ethernet connection from the room so I tried that and got a very good connection upon restart. I was downloading content from the iTunes store and the connection was interrupted - Internet connection was lost. I tried redrafting again several times but to no avail. I went into network preferences and tried automatic location along with several others I have set up but cannot get it to re-connect. Built-in Ethernet is shown as connected and diagnostics shows Ethernet and network settings in green but ISP Internet and server are red. It configured using DHCP and IP address is 192.168.xx.xxx with subnet mask and router showing addresses as well. DNS Server is identical to IP address and Search Domains says "stayonline.net"
I have 2 other Ethernet connections showing on my locations that I believe are related to Parallels (some say Parallels Host-Guest & Parallels NAT and the others say Ethernet Adaptor (en2) & Ethernet Adaptor (en3)). I have tried making them inactive and re-starting but again to no avail. I don't know much about networking and just want to get my Internet connection working while I'm here. I am sending this from my iPhone and would appreciate any help you all can provide. Thanks,
Allan

Sorry I meant restarting not redrafting (iPhone apparently doesn't like the word restart and changed it for me!)

Why is wifi connection lost after sleep/wake mode?

I've had this iMac a little over a year and had not experienced this until a few days ago. Every time my computer comes out of sleep mode the wifi is no longer connected. I must turn it off wifi and turn it back on again to re-establish a connection. Any suggestions? Thx!

Hello tim290,
After reviewing your post, it sounds like after the computer wakes from sleep it does not connect to the internet. I would recommend that you read this article, it may be able to help the issue.
Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus (-) sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Restart your computer.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.
Thanks for using Apple Support Communities.
Have a nice day,
Mario
