Lost ability to connect to the internet on my desktop after installing Mavericks on my laptop, is there a connection?

Hi all,
I recently installed Mavericks on my laptop. I have an Ethernet cable I connect to my modem to gain access to the internet. I have another Ethernet cable I use on my desktop computer and I connect THAT cable to the modem when I want to gain access on the desktop. Right now, I have access to the internet on my laptop but not on my desktop. The internet service provider checked everything and could not find a problem. They suggested I contact Apple. Is there any connection between my recent upgrade to OS X Maverick on my laptop and my internet connection issue on the desktop? Last thing, the internet service provider suggested that the problem lies in some setting or preference...Thank you in advance!

Unless you router is an Apple Airport, I doubt that updating your laptop would have changed anything, but who knows.
I would recommend trying to hold the reset button on your router for 30 seconds. This may fix the issue, but this will probably erase all of your router's settings like wifi passwords and stuff like that.

If you don't want to risk completely resetting your router, I would suggest trying the following:
– On your laptop (which has a connection)
– Go to System Preferences >> Network >> Advanced >> TCP/IP
– Write down the IP number next to "Router"
– – – Mine looks like this:    192.168.1.125
– Go to your browser (Safari etc.) and go to     http://RouterIP
– – – Where "RouterIP" is the number you wrote down before. Mine looks like this:    http://192.168.1.125
This will take you to your router's settings page.
It will probably ask you for a username and password. They probably are:
User:    admin
password:   admin
or
User: admin
Password:   your router/wifi password
Look all the settings on this site and see if everything is set to reasonable values.

If all else fails, then it's probably something to do with the settings on your desktop PC.
Best,

  • My Satellite A25-S279 (WinXP) will not connect to the internet wirelessly since UVerse was installed

    My Satellite A25-S279 (WinXP) will not connect to the internet wirelessly since UVerse was installed. (Rather, I should say
    it 'connects', then immediately disconnects.) When I had regular DSL, there was no problem, but since UVerse installation,
    I can connect ONLY with the ethernet cable.
    Thinking it was my 'old' computer, I took it to the local computer place---they were able to connect instantly (wirelessly) AND maintain connection. Sooo...I've told this to ATT, & had 2 different techs out here, both of whom were very patient & tried EVERYTHING they could think of,  & both of whom failed to fix the problem. They maintain that it is NOT the fault of the modem/router, but is some 'miscommunication' between my laptop & the modem/router.
    Is that possible? Is there a setting I need to change on the laptop? If it worked BEFORE UVerse, and if it STILL works at the Computer store, and if it works WITH the cable, why won't it connect wirelessly?
    Thank you SO much for any thoughts!

    It is possible. While it's not common, sometimes you could have a working router and a working wireless card in a laptop, but they just don't communicate. It sounds like that might be the problem unfortunately.

  • It shows that my computer is connected to the internet but when I try to load Safari it says I'm not connected

    I have reset my router multiple times, and I was connected to the internet just fine before. I have a booster and it was working great until yesterday when it said I was connected to the internet but everytime I tried to load safari it said I wasn't connected. It is working while I am using the hard-line, but I am wondering how to fix the Wi-Fi. I have also reset safari, cleared the cache, and recieved every update.
    Thanks

    I too am experiencing an EXTREMELY slow connection to the internet when my PC comes out of sleep. When I check/troubleshoot the connection, I have all green lights, indicating I should be able to get on line, but it takes about 4 or 5 minutes before I can do so. It seems that this problem started shortly after the iCloud (or i Could as another poster said) was loaded. I know its not my ISP, because my wife, who works on an IBM machine gets right on, no problemo. Is there something going on with either the recent update or the i Could (use to be able) addition? Defective software?
    TIA for any response.

  • The Apple time capsule provides disc memory, a wifi network, and router functions. It would normally be connected to the internet via cable modem.  If I wanted to use a wireless cellular connection to the internet, how would I do that?

    The wireless cellular device would need to have an Ethernet port, to provide an Ethernet signal to the Time Capsule's WAN port.

  • Cannot connect to the internet using Cellular Data after iOS 6.0.1 update

    While installing the iOS 6.1 update for my iPhone 4, I encountered an issue and had to restore it. Since completing the restore, I am only able to use a wifi connection to connect to the internet (apps not working when wifi isn't available, not even iMessage or safari - "Safari cannot open the page because it could not connect to the server"), although I have a mobile internet plan with my carrier. I also tried resetting the phone to its factory settings, but that didin't solve anything. Did any of you encounter this problem? How can I solve it?

    Phone restart > if that doesn't work then do a reset of the settings. Full restore would be the last option.

  • I have downloaded Viber to my iPhone 4s,  it was previously working but now displays a message saying i need to connect to the internet before i can make a call or anything else, My phone is connected but the app does not seem to recognise this?

    I have downloaded Viber to my iphone 4S,  it was previously working,  but as of today it has continually asked for an internet connection when i try to make a call or send a message.  It displays this message while connected to the internet at my home,  or with 3g.  my internet connections seems to work fine on other apps that require this.  I have tried to reinstall viber but i can not not setup my profile becauase the same message displays.  does anyone know how i can resolve this?

    Thanks, as it still will not work, I assume it is damaged and needs to be sent in for repairs.

    You can also check the following:
    * Your modem and/or router are both on and are not indicating errors. The problem may be with your Internet Service Provider (ISP). Contact your ISP for more information.
    * If you are using a wireless connection, that you are using the correct access point.
    * Your Domain Name System (DNS) server translates web addresses (URLs) into IP addresses and is usually provided by your ISP. If the DNS server is overloaded, you may be unable to view some or all websites. For example, if http://74.125.53.99 or http://74.125.159.105 work but http://www.google.com doesn't, you may have a DNS problem. You can use an alternative service such as OpenDNS (http://www.opendns.com/) or Google Public DNS (http://code.google.com/speed/public-dns/).

  • Why won't my Macbook pro connect to the internet, yet my desktop PC will?

    My 13 inch Macbook Pro was purchased back in March of this year, but recently I've been unable to connect to the internet. Within the network settings it says that my Airport is on and has a self assigned IP and that both the ethernet and firewire are not connected. Yet when on my desktop PC, everything seems to be working fine. I've concluded that it couldn't be my router, at least I'm pretty confident it's not.
    I've tried the usual reboot, unplug router routine but it still won't budge.
    Please help!

    Just connected my ethernet cable directly to my macbook, and the internet is working fine. So is this an issue with my router then?

  • Is anyone else having issues getting screensavers and the lock screen to work after installing Mavericks?

    I recently installed Mavericks and now my computer refuses to lock after sleep. Instead of a box that asks for a password to access the computer again, it just opens up back to where it was before sleep. In fact, I can't even get my screensaver to work. I have the screensaver set to one minute (to attempt to get it to work) and it wouldn't even come on. The sleep/lock screen is set to ask for password as soon as it's woken. Same goes for when I open my laptop after it's last use. No password, just instantly on. Is anyone else having this issue? If so, how can I fix it? Thanks!

    I had the exact same problem.. and thank you for the answer..
    It actually makes sense, but I had the 'bouncing camera' problem and never thought of the 'slide'..
    Dohhhhh
    cheers for the post

  • HT1338 I am connected to the Internet, but I cannot download an update because it says I am not connected.  Pls advise.

    How do I download an update when my computer says I am not connected and I am?

    Where are you trying to connect from? Your profile shows IOS 6.0.1. If you are using an IOS device, you'd have a better chance of getting a good response if you posted on that forum.
    If you aren't using an IOS device, more information would be helpful.

  • My MacBook wont connect to the Internet on Ethernet or wifi, but it is working because my iPhone is connected to the same router and so is my friends mac

    If your phone is offline, the ONLY way to find it is to look for it the old fashioned way.  Your phone CANNOT be located electronically if it's offline.

  • WRT 120N- Cannot connect to the internet with more than one PC at a time.

    Before I went on a three month vacation,I could connect 3 or 4 PC's either wireless or wired to my router with no problems at all.I have a desk top and a laptop computer which I use at home.After I returned,I found that I could connect to the internet with only one PC at a time.
    If I was say,connected via my laptop,my desk top would continuously keep getting disconnected and vice versa.I have been reading the suggestions from experts here and have done a few checks based on them.I also cannot get to my router page which is 192.168.1.1 I keep getting a message that says "Problem Loading Page" and this happens with both,Firefox and Internet Explorer.I am running Windows 7 - 32 bit on my desk top and Vista Home Premium on my laptop.

    I presume that this model is a modem **bleep** router as I do not have a separate modem with my system.I have a DSL connection and the firmware version of my router is ver.1.0.If I recall,I did upgrade to the next firmware upgrade a few months after I purchased the router but I am not sure.
    I use both my PC's to run a small business venture and I am worried that resetting the router may cause some other problems and will stop me from using the internet.
    The Command Prompt information above was taken from my laptop.
    Any help will be really appreciated.

    I do not know if the above result is what it is supposed to be but I still cannot access my router's home page.How do I verify if there is a proxy server and if there is one,how do I disable it in my browsers?This problem occured suddenly as a few months earlier all was well.It's getting rather frustrating.
    I suggest resetting the router. Make sure firmware is updated. You can download it here - http://homesupport.cisco.com/en-us/support/routers/WRT120N. After firmware upgrade, reset and reconfigure. Just access the link below to guide you setting up the router.

  • My airport extreme shows a green light, but won't connect to the internet.

    I have an airport extreme, and it stopped working one day, so I reseted it and it's not connecting to the internet now.  It's showing a green light, however, it won't connect to the internet. I live in an apartment complex, so I don't have a cable modem. The router is directly connected to the wall via ethernet. I had the ports checked by connecting the ethernet cord directly to the computer, and the internet is working fine. I tried resetting the router, but it still doesn't connect.

    Your problem is typical Yosemite network.. just reboot the Time Capsule.. no luck reboot the network.. do a restart in correct order.. modem.. wait 2min.. TC .. wait 2min.. clients.
    No luck then do a full reset of the TC and setup in a way that Yosemite can cope with.
    Start from a factory reset. No files are lost on the hard disk doing this.
    Factory reset universal
    Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
    N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
    Setup the TC again.
    Then redo the setup from the computer with Yosemite.
    1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
    eg TCgen5 for basestation and TCwifi wireless name.
    If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
    2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
    3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
    Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
    4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
    5. Mount the TC disk in the computer manually.
    In Finder, Go, Connect to server from the top menu,
    Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
    You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
    However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
    6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
    There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
    You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
    Tell us how you go.
    Someone posted a solution.. See this thread.
    Macbook can't find Time Capsule anymore
    Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
    Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.
    http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-yo u-can-do-to-fix-it/
    Same thing applies to the Airport Extreme or the Express if used as router.. just replace TC in the instructions with AE.
