New iMac knocking out internet/router??

  • Hi all!

    Anyways here's my problem. My router is an old Linksys WRT54GS. I've used this for years with no problems at all. However lately my router/internet getting knocked out and I have to unplug it to restart so everything gets internet access again. The only change to my system is that a roomate got a new iMac. Ever since then is when this problem started.

    Is it possible that its causing this? If so, how can it be fixed? Other connections have also been added since the iMAC was purchased but the only common thread to the problem is that it started happening when the iMac arrived.

    Also I think we went a few months without this problem occurring, howvever today I think its happened about 8 times already and its driving me nuts and I need to solve it finally.

    This is whats connected to the router (which has its newest firmware)

    Wired connection:

    • My PC (Windows 7 64bit)
    • Xbox 360
    • PS3
    • WD TV Live HUB

    Wireless connection:

    • The iMAC
    • Another PC
    • Macbook Pro
    • 2 iPads
    • HP Touchpad
    • 4 iPhones
    • Wii

    The items that are new connections that were purchased after the iMAC are 2 iphones, Macbook, 2 iphones and 2 ipads and WDTV. However they are only sporadically connected and the Wii is never turned on anymore.

    Is there a way to solve this? I suspect maybe I have to give the iMAC a static ip or something but I'm not too knowledgeable about networking stuff. Maybe I just need to upgrade to a newer N router?

    Thanks in advance for any help and advice!

  • I had the same problem with the same router, quite a while back, the thing becoming more and more frequent. Turned out, the router was toasted!  
    Though, by "knocking out internet/router", do you mean that none of the computers on the network can connect to the Internet despite the connection being available? That's what happened to mine.
    I don't have much memories of the router's interface, but I think you have the ability to allow devices on the WiFi only on their MAC address, then you assign static IPs for all of them, it's pretty straightforward or I wouldn't have been able to do that, and... well I don't see any reason why I would help in any way, but it might spare you some troubles further down the road. Does the iMac or any other device tells you you have an IP assigned twice? That kind of things can happen (I really can see why, but it does), and it's quite a pain in the lower back.
  • @Greg818: Hey there! Yeah by "knocked out" I mean no other device can connect at all.

    When the iMac was first purchased for the first 2 weeks my Windows PC would get notice that something was trying to get the same IP as me.

    Guess Ill look into this static ip thing. Thanks!!


  • @evophile: Alright, keep me posted. (I don't understand how this DHCP business works, that kind of things should NOT happen)
