Loss of Internet connection after after power "Blackout"
I have a Linksys WRT54GS router connected to Charter.net cable modem.
I do not have a static IP.
This summer we have had several power blackouts. The electricity is gone anywhere from 10 seconds to a lot longer.
When power is connected again, the router is not able to receive an IP address from the Cable modem. Therefore the LAN side of the modem works, but no access to Internet. After a power restart of the Linksys Router I am again connected to the Internet. It seem that the Router boots before the Modem and when asking the Modem for the IP address gets no answer from the slower booting Modem. When I am at home it is an easy problem to solve but when I am in another part of the Country I loose the connection to my Base Computer at home.
?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />
Is there a solution???
what is the firmware version on the router?? try reducing MTU to 1452...let me know if you have any issues will get back to you.
thanks

Loss of internet connectivity after upgrading to windows 8.1
Hi, After upgrading to windows 8.1 from windows 8 i am experiencing major problems , loss of internet connectivity for no reason both I.E. and G/CHROME are now taking an age to open there are no virus issues as far as i can see.
I have uninstalled and re-installed windows 8.1 about four times over the past 9 months or so and the same thing happens after all the updates are in it runs like a dream for say 6weeks or so then i get the same faults as described above then i uninstall/ re-install ok for 6 weeks .
I would apprieate any help or advice thanksHi @BMATH
Thank you your query.
I understand that after updating to Windows 8.1 about every 6 weeks you loose wireless connectivity for no reason and the web pages are very slow to open. If you uninstall and reinstall Windows 8.1 it works fine again for about the same amount of time. You have done this about 4 times with the same result each time.
Do you know if there is any changes at that time , perhaps an update?
You stated you do not believe you have any viruses. Just to be sure here are two links that will help confirm that.

Microsoft Safety Scanner
After updating to Windows 8.1 have you checked for Windows updates?
Have you ran HP Support Assistant ?
Here is a link to Troubleshooting Wireless Network and Internet (Windows 8) that may also help.
If the issue should remain please contact HP support for assistance.

Loss of Internet connection after software upgrade
After carrying out a software upgrade last weekend which included iTunes 10.4.1, Remote Desktop 3.5.1 I'm finding that my internet connection stalls and the iMac hangs after unspecified periods of time. Sometimes I can carryout a restart, other times I require a hard reset to get the iMac running again.
All will be fine and then once again Internet will stop working and eventually the iMac will hang again.
I've tried a number of actions to see what's going on, there are no processes hung or taking up huge ammounts of CPU. If I try to refresh the IP address of the Ethernet connection from the router this is possible, but you still can't browse to a page.
I've also tried deleting some of the .plist info from the System Prefs area and having Lion re-build them but that hasn't worked either.
My next thought was a complete re-build of Lion from scratch, but before I start down that road, has anyone any other ideas?
System specs are;
iMac 2.8GHz C2Duo
4GB Ram
Running Lion 10.7.1
Many thanks,
Stuart.Hi Larry,
If you go to Control Panel -> Network Connections (For Vista and Windows 7: Network and Sharing Center) -> Double click on your Network Adaptor (Vista and 7: Top left hand corner of the Network and Sharing Center, click on 'Change Adaptor Settings' and double click on your adaptor. Click Properties and scroll down to 'Internet Protocol Version 4 (TCP /IPv4), click Properties and make sure that 'Obtain an IP Address automatically' and Obtain DNS server address automatically' are ticked. Click Ok, then OK, then finally close. Check to see if you have connectivity. If you don't, go to start, in Run (Or in the search bar) type 'cmd'. Once Command Prompt opens, type 'ipconfig /flushdns'. Close Command Prompt and check again. If you still don't have Internet connectivity, go to Internet explorer and click Tools -> Internet Options (If you have Internet Explorer 7 or 8, press Alt before looking for tools. This will make the bar appear). Go to the Connections Tab and click on 'Lan Settings'. Make sure that you do not have 'Use a proxy server for your LAN' ticked. Also make sure that you have 'Automatically Detect Settings' ticked. Once you have done this, click Ok, Apply and Ok and check again for connectivity. If this didn't resolve your problem please post back
Sorry for the long answer

I've lost internet connection after a power outage; how do I restore?
Check with your internet provider for help. Your modem or router could have been damaged if they did not come on after the outage. If your modem and router look OK all you should have to do is restart your iMac.

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. -
I'm having problems with my internet connection after installing OS X Lion. Is this a known problem or just a local problem?
After +/- 10 to 15min my connection is gone.
Does anyone have a sollution?Lots of people are having the same problem, you're not the only one, belieeeeve me.
Just Googling the problem gets you tons of people complaining about the same thing, SOMETHING is up with Lion what wasn't happening with Snow Leopard. i just bought a new Imac and it CAME with Lion, so i started experiencing this internet dropout immediately.
It's been going on for the most of a year it looks like (at least by the dates from the threads i've been reading)
So your best bet is to fiddle with the System Preferences and read what other people have used to make theirs work. i'm doing that myself right now. I already posted a similar thread last night trying to figure out why my connection kept on dropping, i got a reply which linked me to a site. i followed the instructions there, so far so good, but i'm just being cautiously optimistic.
i'm gonna call Apple today and see if they've found anything, though seeing as this is a problem right out of the box there may not be an immediate solution. Good luck hunting for a solution :3

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.

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. -
Server loses internet connection after creating virtual switch in hyper-v
On a fresh Server 2012R2 Essentials install, I set up Hyper-v and created an external virtual switch. Connection to the vm is good but Health Report no shows loss of internet connectivity and that the router is incorrectly setup.
However, I still have a working internet connection? I worry that the server may not update or allow Anywhere Access at some time. Any suggestions? ThanksIf Hyper-V virtual switch behaves strange and server is destined for testing, then it's correct and I recomend delete this virtual switch and create it again.

Unexpected shutdowns and loss of internet connectivity on brand new 420t
Hi,
I was experiencing unexpected shutdowns (would see safe mode choices when turned PC back on) and also intermittent internet connectivity issues.
To Fix:
In device manager, I turned off the option in the Realtek Network Controller Power management tab to allow the computer to turn off this device to save power.
It's been working like a charm so far (2 days). I'm not so sure HP should be building PCs with this option set. There are no updates that I haven't installed either. PC still sleeps (can see nic lights go off) and wakes up just fine.
Other that that we really like this PC...Beats Audio wasn't impressive with only the internal speakers, then I tried a good set of external tweeters and a subwoofer and then it was realized.
Hope this helps someone.Troy,
Thanks for the suggestion. It sounds like you've heard that others have had this problem. Is that right?
And are you suggesting that the kernel panics and the loss of Internet connection are related? They often happen independently of one another.

Loss of Internet connection through TC after sleep.
I have a Netgear ADSL Wireless modem which is connected to a TC in bridge mode.
So here is what happens, I am connected wirelessly to the TC and can access the internet no problem. I then put the MacBook Pro to sleep, then on waking the MacBook I have no internet connection. But if I select the wireless network of the Netgear I do have an internet connection. The MacBook then at some point reverts back to the TC wireless network and all works OK. I think it reverts back to the TC network after a sleep period.
It does not do this every time but it does it enough to have become annoying.
I presume that on those occasions that I have no internet connection through the TC that this is because the TC is otherwise occupied?
Is there a way to cure this problem?

Problems with your internet connection after upgrading to iOS 7.1.2
After upgrading to iOS 7.1.2 on my iPad Retina display does not connect to the internet more. Recognizes the Wi-Fi network but can not connect to the internet. The same thing happened to my wife's iPhone 5s, while my had no problems ...
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at
http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
• Launch Settings app
• Tap on Wi-Fi
• Tap on the blue arrow of the Wi-Fi network that you connect to from the list
• In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
