Q: Cannot access internet on strong wifi

I've tried to find an answer using suggestions these discussions, but nothing seems to work.

 

the wifi signal is strong

in network preferences I have green status for all elements except ISP which is amber, internet which is red, and server which is red.

ive run the diagnostics, but I get stuck in the loop when it ask to reset any devices (router, amplifier). I reset them, and then im asked if there any devices between the computer and the incoming service.

IVe added new DNS

IVe tried to renew the DHCP lease

what else can i try??

 

thanks

A:

So your Mac is connecting to the router and getting the thumbs up but the DHCP service on the router is not giving your Mac an internal IP address.  I can tell that because you are seeing the self-assigned IP address of 169.254.X.X  This occurs when the router has failed to deliver an IP address, the Mac, and all computers assign that address to itself until an IP is delivered.  At this point I can tell you for sure that it's not your Mac itself, but something in your network.  The router is what assigns the internal IP addresses to all the internal devices using a service called DHCP.  There are a number of reasons this service can fail to assign an address.  it could be blocking the connection or it could have reached a device limit.  I would suggest contacting your router manufactuer at this point.

    I noticed that you hadn't mentioned any details on the machine you're using. You're posting in the iMac help group; I mention this only because this problem sounds like to what some mobile users report having experienced.

     

    I mention this because, if you're using an iMac, you could connect directly to the internet via Ethernet - which is a little more reliable, given it uses a cable connection. But if you're using wifi as part of a network, how many other devices are connected.

     

    Do you use Airport? If so, what does your display indicate?

    It's an iMac.

     

    I haven't yet tried a direct ethernet link - I'll do that later this week, when I have the chance to take the machine downstairs to the router.

     

    I'm running out of ideas . . . .

    I Dont use airport - i have a swisscom DSL router and a repeater.

     

    the signal is strong, but the service is slow to my daughters MacBookAir, and non-existant to my iMac - which is strange because a week ago it was fine!!

     

    ive run out of ideas now ....

    After much discussion I persuaded my provider to try a replacement router. This arrived today, it's installed and all is working perfectly (so far).

     

    Thanks everyone for your help.

     

    Best regards
