OSX and a Linksys Router - How to Make WORK!?

    My G5 arrived on Wednesday and I'm as happy as someone who is really happy. I've been using a G3 for the past 3-4 years with OS9, so this is my first real experience with OSX.

    With the G3, I connected to the Internet through a Linksys router, then to my RR cable modem. It works fine. However, when I try to hook this thing up to my G5, it doesn't work. When I bypass the router, I get online just fine, but it won't connect through the router. When I hook it all back up to the G3, the router works. I've tried to make the TCP/IP settings on the G5 match what I have on the G3, but it won't work. The Linksys didn't come with any Mac software, and I don't remember ever installing any on the G3.

    Should the G5 work in the same manner as the G3? Any ideas?

    Are you using DHCP or is the router assigning a particular IP address?

    If you turn on DHCP, the G5 will "find" it and you should be all set. I assume you picked the correct option for networking when you booted the G5 the first time...?

    Re: DHCP???

    Yes, I'm using DHCP. It picks up the address but it won't connect to the web. I get an instant "can't find" message as soon as I start Safari. No looking around or waiting, just BAM with the message.

    I don't remember what I told it when I first set it up. But it world when I pull the router out of the chain and go through the hub to the modem.

    Make sure the router is set to DHCP upstream to the WAN as well. You can check the DHCP lease from your provider in the DHCP tab of the admin page.

    How about connecting both the G3 and G5 to your router. Test connectivity between the two systems. That will verify you have IP connectivity.

    Also, make sure you are getting DNS entries from your router. Without DNS, you will get that message when you try to surf with names.

    However the router is set, it works with the G3 but not the G5. Is there a difference in how the G5 would connect?

    Thanks everyone!

    (I'm at work on a PC so I can't test things till I get home)

    turn everything off (computer, router, modem)

    plug everything in

    turn the router on

    turn the computer on

    direct your computer to

    reapprove the configuration.

    it should begin to work.

    I was able to access the router's setup screen on the G5, and I poked it around a bit, but I'll give that a shot. Thanks!

    Is that a wireless connection to the router or a wired one?
    In the former case you need to upgrade the firmware version of your linksys in order to make it work with your new Airport Extreme (I suppose) card into your G5.
    If not working try to lower the bandwith on the linksys from 11Mbps to 1-2Mbps. There's an issue between Apple Airport Exteme cards and some linksys wireless routers.

    If you are on DSL make sure you go into the Linksys admin area and reset MAC addresses. DSL companies seem to like limiting the number of concurrent MAC addresses they will allow.

    I've had a lot of bad experiences with linksys wireless routers and all computers. It seriously got to the point where linksys tech support told me to return it and use a different product.

    I love Linksys. WinXP, OSX and Linux machines all run great on my network. Including this laptop, which uses their 802.11b card.

    It's not a wireless router. I'm using a cable modem with it.

    Does my G5 come equipped with an Airport card? I thought that was an extra?

    I've got a similar setup. Do what the above post says and pull up that address in your web browser. As soon as I went through this (leave username blank and password as 'admin'), it worked like a charm. Good luck.

    Um, is it a router or not? ;)

    If you test connectivity between the two boxes, and it works, then proceed to make sure you do not have any ACL's by MAC address or something like that (although people don't normally do this except wireless).

    I've got a Linksys Router w/wireless and haven't had a problem with any OS. It really seems like there is a config problem on the G5 itself. If you haven't changed many settings in the router, then most likely, the G5 config is the problem. I would ensure all DNS entries are populated. It seems to point to DNS, because you can web browse to the Linksys from the G5.

    For a test, you can try to browse to an IP address when the G5 is connected. For example, type any one of the following IP's to get www.yahoo.com:,,,,,,,

    If any/all of those work, then the problem is DNS. If you open a terminal, type the following and post the output from each or PM me:

    cat /etc/resolv.conf
    cat /etc/nsswitch.conf

    The post above about limiting MAC address won't apply to you if you are using default Linksys configs. Simply put, the MAC address the ISP sees is the same (the Linksys WAN MAC), no matter how many different systems you run behind the Linksys.


    And, by the way, do NOT leave the password as 'admin' or leave the default wireless set to the default. This is a good way to let a hacker know what type of devices you are running. If they figure out it's a Linksys, the next thing they'll try is the default password.

    Trying to get my G3 to work with a Linksys Router

    I am having a similar problem. I have a G3 Power Book with OSX 10.2 wired to a Linksys Router. I can not get it to see the router to save my life. I notice that when I use DHCP, by default my G3 shows a sub net of, while my router is set to I would change the router to match the G3, however, the router only lets you change the sub net to about 10 different predesignated sub nets, non of which match the G3. Could this sub net thing be my problem?

    this article details how setup your router with a specific isp.


    this might be helpful too.

    the first article should solve any problems. just a note remember that sometimes your MAC address of your router maybe have to registered with your isp, so MAC address cloning maybe needed or you just change the MAC address you have registered.

    FYI MAC address is "MAC Address is a unique 48-bit number assigned to each Ethernet network adapter and maintained by the IEEE"
