Connecting wirelessly with a router

Hey all,
Got a question about wireless internet.
I have a Netgear router that is connected to my PC and Airport on this new Mac is picking up the signal broadcast by the router in order for me to connect to the Internet.
My question is: if I get rid of the PC, which I intend to do in the near future, will the router have to be connected to this Mac in order for me to connect to the net? Because I actually want to be able to connect wirelessly around my house without being tied down like the PC was. Furthermore, is it possible to just have the router plugged in but not connected to a computer as such and still broadcast the signal needed for me to connect to the net?
Any information on this will be greatly appreciated.
Thanks,
Joe

Joe,
No, you do not need to have any computer connected directly to your router. I assume that the router is also connected to a cable or DSL modem. This is all that is required to gain access to the internet; the modem establishes communication with your ISP's server, and the router gains a "public" IP address. The router then grants "private" IP addresses to every computer or device that connects locally within your network (regardless of whether that connection is "wired" via ethernet or wireless), and shares its single public IP address among the private addresses it manages. That's how routers work.

  • I have a TC which is connected wirelessly to my router.  I would like to connect a mac in another location via ethernet to the TC.  I can't seem to get it to connect.  Am I missing something?

    I have a virgin Superhub which serves my wireless needs throughout the house.  I have a Timecapsule which connects wirelessly to the router with no issues.  I can backup my MBP over wireless easily.  I have now got another machine in a different part of the house that I would like to connect to the network.  It doesn't have wireless so ethernet is the only option.  I have a number of options 1) run cabling - not really possible  2) buy a powerline network system or 3) use the timecapsule to connect to the network/internet. 
    I like option 3 because
    (a) - I don't have to spend any more money and
    (b) - my wife wont complain about cables also see (a)
    Should using mixed wifi and ethernet clients on a timecapsule work?  if so is it a feature I can use out of the box so to speak?
    Thanks

    No a TC cannot do what you want.. it is now in dumb stupid wireless join mode.. and it turns off the ethernet ports.. in case you want to use the TC as a wireless bridge to multiple clients which is plainly wrong.. (only airport express is allowed to do this since it has only one ethernet port).
    Welcome to Apple. (The plainly wrong above is a figment of Apple imagination.. of strict network protocols.. but unhelpful for a home device. maybe also to encourage sales of expresses.)

  • Hp laserjet Pro 200 M276nw won't consistently connect wirelessly with iMac

    I'm on my second brand new hp laserjet Pro 200 M276nw in 3 days, it will not consistently connect wirelessly with my newly purchased (8days old) Apple refurbished 27" iMac on OSX 10.9, i7 chip & Fusion Drive.  The hp laserjet will sometimes connect wirelessly immediately after clicking "print" on the iMac, but about half the time it says "printer not connected" & takes 2-4 minutes (or longer) before the devices do connect. I've called hp support many times, they're reset various things via remote takeover of my iMac, the printer will work for a few of minutes but then the same problem returns. AppleCare made sure I have the
    correct Airprint driver installed & also checked my settings, but says they don't know why this is occurring. I've also verified that our newer (6 months old) AT&T router is functioning correctly.
    My older hp laserjet (CM1312nfi MFP) has worked flawlessly since 2009 via USB connection with my old iMac (still on Snow Leopard), I assumed it would continue with the new one, but there is no software update for Mavericks & the scanning feature won't operate on the new iMac. Hp says it is a discontinued model. The new hp laserjet is a successor model to the older one, they are both very similar except for the new wireless feature. 
    I can print fast & wirelessly from the new iMac via a different new hp inkjet printer (8600 series) here in the house. This inkjet printer is less than a month old, I installed it myself for a Windows laptop here, it has never malfunctioned.  Unfortunately it's upstairs & I do not like inkjet print quality, I need a good laserjet here in my office downstairs next to my iMac.

    HI there
    Did you manage to sort this issue out - as I have exactly the same problem.
    Lots of similarities as I also have an inkjet 8600 which works via USB and wirelessly no problems at all!
    I always  buy HP printers as they are usually easy to set up - but this one is making me tear my hair out!
    I've even upgraded to Yosemite and downloaded the new drivers from HP - no success.  The printer will print one page and then become unavailable.
    I can print via USB or wireless direct - but not just via my wireless network which is what I want to do!
    No responses posted - so assume no one has a fix.
    aaaargh!!!

    This is a known, ans ongoing issue. Rest assured you're not the only one affected. There are several threads here already discussing this, I suggest searhing them out if you want more details, and possible work-arounds for locally hosted content.

  • Can't connect to internet wirelessly with WRT120N router

    ok, it's nearly 4am and i've been trouble shooting this problem since 11pm... love the technology, but it completely evil...
    let me start off by saying i'm not too tech savy. took a couple computer courses in high school and thought it was my passion but they got way above my head in college, so i settled for art (those classes are much easier to pass as long as you draw your homerwork, don't blow up your sculpture etc etc)
    anywho, i bought a brand new computer today since i play wow and my old computer was nearing on a decade old and had nearly a dozen manufactury resets from all the viruses from downloaded music. i don't know the make of the new computer (just spent like five minutes looking over the box and it doesn't seem to say) and i literally walked into best buy and walked right up to the computer department store head and said, "which computer should i buy to play wow on for less than $600." he thought for like thirty seconds and pointed to an ASUS and i immediately bought it. took it home, watched tv for a couple hours, then went to set it up since i had a raid in like two hours, thinking, "brand new computer, nothing's gonna go wrong!..." 
    well it did. my router gives me grief from time to time, so i spent the first hour unplugging, resetting, refreshing (i think that's what the button by the blue lights that has the circling arrows does) and nothing. so then off to the interweb since... oh! this might be important! the one computer i'm on now that has a hardwired connection is running normally, not great, normally. and i just checked my mom's ipad, it's on the network too. my phone, a samsung galaxy s 4 had been connected since i had it, and decided to stop connecting when at least until i noticed i couldn't connect my new desktop and my gf's phone, an iphone 4 wouldn't connect either... in total, i think there's one wired desktop connection, my fail wireless desktop connection, wireless laptop that hasn't been opened in months, an at&t signal booster, an ipad, and 4 phones that connect when they feel up to it. my old iphone 4 i ran on 3g because it was more reliable than my wireless. there's never more than 3 devices running at once. i've seen a few threads mentioning too many devices on one network. could that be it? i hope not. we have comcast as a provider too, if that helps.
    oh, and maybe i should describe my problem more clearly. on my phone, when i go to the wifi settings, it still list my network as one i'm linked too, it's just "not in range" and my new desktop can't see it at all. pretty sure it's not a hidden ssid because i connected my phone to it recently and had no probs. also, i'm fairly, but by no means 100%, certain that it's not the wireless card in the computer because i can see a few other networks and my phone had already been on it without giving me problems until earlier today. 
    if you know how to help, please be thorough in explaining it, and if i need to give more info, i'll try my damnest. please please please!!! help me, i spent all my money on this **bleep** computer and don't have anymore to buy another new router.

    Hi there. To start, that blue button that you have been pressing on the router is the Wifi Protected Setup button. You press that button when you want to connect a new wireless device that supports Wifi-Protected Setup to connect to the wireless internet via your wireless router without having to enter anything on the new wireless device. So it means, you did not reset the router. I would like to verify with you though because it is not clear to me (sorry), how do you want your new desktop computer to work? Wirelessly or with Ethernet cable plugged-in? If it is for wireless, you will only need to connect the computer’s wireless connection to the router wireless network and to enter the wireless password if you have wireless security enabled on the router. Also, the router should be able to provide simultaneously internet connection to multiple devices – be it wired or wireless. Sometimes the reason why the wireless would not work is when there is wireless interference in the area that you will need to change its wireless channel to something else. To have wireless security enabled on the router is helpful as well in making sure that the router will provide a better connection speed.

  • Printer not connecting wirelessly with iMac

    MacBook Pro working on OSX 10.4.11 wirelessly with Epson PX710W. Tried to add iMac on OS X10.5.8 but failure to connect on every attempt after numerous sessions with Epson Support. Have repaired permissions having previously run verification of HD which was reported OK. Reset printer system and reinstalled drivers without success. Still receiving message job stopped on both computers. On setting up the sample page to print, when selecting the PX 710W printer or the other printer option, there is a quick flash. Then the MacBook will not print due to 'communication error'. But if the PX710W is turned off and then on again, the MacBook will print.
    Any help would be appreciated.

    Switch router to channel 1. Disable and remove all security on the router. Now try to connect to your unsecured SSID. Are you successful?

  • Connecting wirelessly with Printer

    I've had several questions about setting up a new iMac. The groups have been very helpful. I guess I can only work through one concern at a time, so here's another. I have internet cable (Mediacom) and plan to get Airport Extreme so that I can place the new iMac in another room in the house. The specs on the iMac say it has BlueTooth 2.1. I have a HP AIO Model 8500 printer, which will be moved also, but it will be across the room from the iMac. HP has a BlueTooth adapter to make this printer wireless, but the adapter is BT 2.0. Do I need to look for an adapter, not necessarily HP brand, that is 2.1?
    My desktop runneth over! As we used to say in Apple IIE!
    Thanks!
    Martha

    If you have the base model AIO 8500 it has both ethernet and USB connections. It is NOT recommended to use BlueTooth because it extremely slow for printing. However if you have the AIO 8500 wireless or 8500 Premier both have wireless built right into them. With the latter two models you can set up a true wi-fi printer meaning it will perform all of the functions (print, scan, fax and copy) wirelessly. You just wirelessly connect it to the router and as long as it's within range of the router you are set. If you have the base model your best bet is to connect it via ethernet to the router, this will still give you a true AIO experience. If you connect it via USB to the Airport Extreme (AE) it will ONLY print (no fax, copy or scan) because the AE only supports USB printing.

  • WRV54G - Problems connecting wirelessly with Windows 7

    I'm unable to connect wirelessly to router using a HP laptop with windows 7. I have 2 xp laptops that connect without a problem. The HP laptop finds network, but once I click on network to connect, it does not ask for the security code therefore I can not connect to network.

    Hi. I think you need to verify your router MAC Filtering. I would suggest to disable it first. Check this link,
    http://linksys.custhelp.com/cgibin/linksys.cfg/php/enduser/std_adp.phpp_faqid=20600&p_created=125498...
    Also, make sure you're using the latest firmware for the router. Don't forget to manage the Profile of the card as stated on the link provided above. Thanks.

  • Connection problems with WRT54G Router PLEASE HELP!!!!

    Hello all,
    Im having a huge issue and im hoping that someone can help me. Awhile ago i changed what i believe to be my router settings using 192.168.1.1 and i believe i added WEP secuirty. I changed my password i know that much. Anyway my problem is this - When i try connecting a router to my computer, i cannot access the internet OR the 192.168.1.1 setup. I just get a yellow caution sign on my wireless settings (running Windows 7), but when i connect my cable modem (Comcast) to my computer, i can access the internet. I have reset both the router and my cable modem MANY times (hard resets) and STILL cannot get the setup page for the router. I have TWO WRT54G rourters and BOTH do the same thing when connected to my desktop , yet BOTH work fine on an old machine running XP, so it is something i did with this computer. Can someone please help me solve this issue? any hlep would be appreciated as i am stumped and do not know how to fix this and cannot use WI-FI or my Xbox 360 until i can fix this..Thanks.

    Check the IP address of your computer and see if it's in range with the router's IP.

  • CAN'T SET UP INTERNET CONNECTION WIRELESS WITH EA6500 AC1750

    GOOD AFTERNOON EVERYBODY. MET A PROBLEM WITH MY NEW ROUTER. I DID TRY TO CONNECT MY PC WINDOWS 8 WIRELES. IT'S SHOWS CONNECTED TO ROUTER BUT ACCESS LIMITED, NO INTERNET CONNECTION. ANY IDEAS HOW TO RESOLVE THIS PROBLEM? I FOUND SOME INFORMATION THAT IT'S WORKS, BUT HOW?? MY LAPTOP WINDOWS 7 WORKS FINE, IPAD TOO. THANK YOU FOR ANY HELP.

    Hi ivan.kishkin, were you prompted for the password when you tried to connect the PC wirelessly to the router? Did you make sure to type it in correctly? You may actually try to remove preferred networks on the computer also and reconnect to the wireless network. You may refer to this link, http://kb.linksys.com/Linksys/ukp.aspx?vw=1&docid=85537a14b0214be48217c733bba9ac65_Removing_Wireless... and use the steps for Windows 7. Usually that helps. 

  • Cannot connect wirelessly with wpa_supplicant or netctl

    Hey, I just installed arch linux. Also, I feel like I've accomplished some rite of passage just registering for these forums, as I had to get that command for the security question figured out (it failed a few times) then manually copy it to my laptop, which I'm using now. Anyway, here's my problem:
    I failed to properly configure my internet connection while chrooted, as per the beginner's guide. Now I'm trying to fix it; I believe it's a problem with my config file. Here it is:
    Description='Home wireless; WPA-encrypted'
    Interface=wlp7s6
    Connection=wireless
    Security=wpa
    IP=dhcp
    ESSID='HOME-3D58'

    # If your key starts with ", write it as '""<key"'
    # See also: the section on special quoting rules in netctl.profile(5)
    Key='#######'
    # Uncomment this if your ssid is hidden
    #Hidden=yes
    I sure hope I copied that right, I'm manually copying it from my desktop (where I just installed arch) to my laptop, which is up and running crunchbang.
    when I execute
    netctl start home-wireless
    I get the output
    Job for netctl@home\x2dwireless.service failed. See "systemctl status netctl@home\x2dwireless.service' and 'journalctl -xn' for details.
    executing the former (systemctl status....) gives

    Loaded: loaded (/usr/lib/system/[email protected]; static)
    Active: inactive (dead)
    Docs: man:netctl.profile(5)
    executing the latter (journalctl -xn) gives: (NOTE: dates and times have been left out because I'm tired of typing all this) also, replace <mac-address> with the mac address of my router (at least, I think it's my router...)

    Derp.
    when I try to use
    iw dev wlp7s6 scan | grep SSID
    I find my router (HOME-3D58). I then ran
    wpa_supplicant -B -i wlp7s6 -c <(wpa_passphrase "HOME-3D58" "#######")
    then, the console outputs
    Successfully initialized wpa_supplicant
    however, if I try to ping any website, I am told that the "network is unreachable"
    halps?

    Sorry because I am reading your post very fast and no deeply.
    But, I think parameters like essid and key must not have quoting.
    essid=myessid
    key=/"####what you get from wpa_passphrase
    This message:

    not means you are connected.

  • Connection problem with EA3500 router

    System consists of cable modem connected to EA3500 dual router and also have a Linksys range extender.  Have several wireless devices including desktop PC, cell phones, and tablets that all connect to wireless network without any problem.  Have password set up on system.  Having a problem with one Acer laptop - when I view my wireless connections I can see HOME and HOME-EXT and it will connect fine with the EXT (range extender) signal but will not connect with the base router that is shown as HOME even though the home connection shows a stronger signal that the ext link.  Have checked to make sure that router password is correct - laptop will sometimes connect to HOME for a few seconds and then display "limited connection"
    No problems with wireless connections with any other devices.  Have rebooted everything in the system with no luck.
    Have also tried deleting HOME connection and then reconnecting it.
    Any suggestions?
    Thanks for any help that anyone may offer.

    On the laptop did you try to forget the HOME network and reconnect?

  • Can no longer connect wirelessly with other computers

    I have an iMac and a Macbook Air.  For some reason I can no longer connect wirelessly between the two. They don't show up in Finder.  Therefore I can't use "Remote Disk" on my Macbook Air to install programs.
    Recently I switched from using an Airport router to a Cisco router. Could this be the problem? I can still connect to the internet through my wireless network, but can't find my computers.

    Hello,
    All the information you need is printed on the back of the Hub. There are two passwords, one for the Wireless setting (WPA password) and one for access to the hub (Admin password).
    (Taken from http://www.jarviser.co.uk/jarviser/images3/newhubpswd.jpg  ).
    If you have forgotten what you changed the admin password to, then I'm afraid you're lost and you should factory reset your Hub:
