Spyware and Malware is always the one of the first suspects in internet connection problems. Run anti spyware on the computer first.  If that does not work, you must narrow down the problem.\n\nThe repair button does a bunch of tasks that can all be done by themselves at the command line.  Next time it happens, instead of hitting repair, go to start&#92; run, type cmd and then enter.  Then type these in, in order, and check your connection after your run each command.  This will narrow down the problem.\nipconfig /renew\n-that ask the DCHP server to keep giving you an IP\narp -d\n-that flusches the Address Resolution Protocol cache\nnbstat -r\n-that reloads your Netbios name Cache\nnbstst -rr\n-that sends an update of your Netbios name\nipconfig /flushdns\n-that flushes your DNS cache\nipconfig /registerdns\n\nTry those untill you narrow down exactly which one it is that does it, and that is a really good place to start for further troubleshooting.

Good information to help you resolve this would be:  new or used computer?  It could be shutting down for a multitude of reasons...  The first to come to mind is temperature.  Most motherboards shut down a few degrees before the processor's thermal breakdown point.  You may want to see that your heatsink is seated on the processor properly, and that any and all fans are functioning.\n\nAnother common culprit would be a virus.  Look for a free program that will let you do a boot time scan of your system.

Have you tried powering everything off and back on?  Just because one computer can connect doesn't mean that the laptop is at fault.  I've had this problem with wireless routers.  First thing to try is to power everything off and then back on.

i dunno about the lock-up thing.. but the shutdown thing MIGHT BE the infamous remote procedure call error (RPC) (that is.. if u r using XP).. It would give a countdown before shutting down the pc. It is becos of a goddamned worm. Try running an antivirus scan to flush out the worm.

If by „shut down” you mean it powers itself down, its obviously adapter problem (could be both software corruption or hardware malfunction). \nIf by “shut down” you mean you loose internet connection, check time of LAN DHCP lease in routers interface.

There is something wrong with the server that u go through when u connect to the internet.  Nothing u can do about it.  It will be recognised by your service provider and fixed. Usually doesn't take too long.

(1) Turn off firewalls, popup blockers and privacy programs just to diagnose.\n\n(2) Turn off all browser toolbars.\n\n(3) Check LAN settings under Tools>Internet Options>Connections, make sure that there's no Proxy server there (unless your ISP specifically says you need one)\n\n(4) Run a virus/spyware scan/clean.\n\n(5) Verify your actual internet connection and all of your settings with your ISP.\n\nIf you're getting "page can not be displayed" on every website you try to go to, your problem can be anything from total lack of internet connection to a rogue piece of spyware that has corrupted a necessary part of your networking configuration files.  It can be a tough one, but these steps fix a lot of problems that you describe.

" This connection has limited or no connectivity. You might not be able to access the internet or some network resources" \n\nYou can go to the properties of your NIC and uncheck the box for Notify me when this connection has limited or no connectivity then restart your computer. After which, check if you still have the same error.

nothing to worry about its just a normal error and can be ignore for a few time,  it might occured due to congested network, \n\nis the problem repeat itself again and again even after a reboot, then we had a problem, write down to problem clearly with the excat error code and add it herre by  adding details to your question.\nGood Luck

Random reboots/crashes/freezes could be due to several reasons,  including RAM, hardware issues, etc., but rather than waste everyone's time playing "20 question" type guessing games, just do the following and post back with the info so that we can narrow it down some.\n\nGo to control panel/ system / advanced Tab/ startup and recovery box/ settings button/ sytem failure  and uncheck  "restart on system failure" ( take the check out of automatically restart box )   ,   and check the Write a system event, and the Admin alert boxes (check "send admin alert").     This will force a BSOD on the next crash (freezes/restarts =  crashing) that posts the Stop Error Code.     On the next crash write down the exact Stop Error Code and post that exact error  here back on this thread.  \n Also go to your device manager (devmgmt.msc) and check the properties  and look for anything suspicious and check that the settings are where they should be.  \n      \n  Check\n\n1.  Overheating(Open the case and check to see how much dust has collected inside it, and  if there is alot of dust get a can of compressed air and blow the dust out and clean out all dust bunnies, etc. on the heatsink/;fan combo,etc.; and be sure all the fans are spinning and properly functioning )  \n\n2.   Poor power supply   (weak power supply or noisey / dirty electricity) \n\n3.  Bad driver or drivers not updated,  or a device conflict.   Pull the connectors and push them back on. Reseat all of the cards. RightClick - my comp/properties/select the hardware tab/click device manager/see if there are any "!" next to anything.   Try updating the drivers from the manufacturers' websites.\n\n\n4.    Not enough memory or bad Ram.   Missmatched ram or a bad stick of ram  will cause this also.       (Run Memtest86: = http://www.memtest.org and  \n  FREE RAM Diagnostic Tool. -  CST Inc.s DOS based DocMemory  =  http://bucarotechelp.com/computers/default.asp )   .\nYou might need to add more Ram.\n\n5.   Could be  IRQ conflict  \n\n6.  Perhaps the CMOS battery on the motherboard is going bad and needs to be  replaced. Check it to be sure.\nAlso check your pc clock's time and day, to be sure it is set correctly. \n\n7.   Hard drive could be failing.       \n\n8    Right click desktop/properties/screen saver/Power/Hibernate tab ,and make sure  hibernation is not enabled, and cleann out your   Cache & Cookies & Temporary Internet Files and Folder: = http://www.coloarts.state.co.us/cleanFiles.asp\n\n9.   Make sure you have updated all programs and hadrdware.\n\n10.   Motheboard short (loose screw, misplaced mounting standoff ,  etc.) ?\n\n (Note: Will it boot into   Safe Mode?  Hit F8 or F5  right after the BIOS screen to get boot options.  Does it also happen in safe mode?)

Couple of possibilities, bad NIC, bad patch cable, or bad router. \n\nPacket loss most often occurs believe or not from a bad patch cable.

Go look at your power settings in the control panel and disable standby.\n\nWhat happens when you use the start button to shut down the computer?  SOmetiomes viruses and bad stuff will hang during shutdown. Make sure your antivirus software is up to date and running.

There could be issue with the BIOS. Check for your computer Motherboard vendor.\n\nThere could be BIOS update.\n\nSynchronizing the time online is a temporary solution. Once you disconnect from Internet it will again go back.

Two most likely culprits:\n\nPower & Heat. \n\nFirst clean out your computer. Get rid of the dust, clean off the fans. \n\nIf that doesn't work buy additional system fans.\n\nIf that doesn't work replace your power supply with a larger wattage one.
