 Apple Network Issues
Apple, Network connectivity
OK... This is somewhat weird. The previous IT Admin created a network using 10.0.0.X. No big deal there, but the gateway is 10.0.0.5. For some reason, it seems that only Macs and iPhones have an issue being about to get on the internet using this configuration. Apple products connect - get ip, subnet, dns right - (wifi and wired), but they cannot get out... Very strange. Neither fixed or DHCP works. I have thought of changing to a more usual 10.0.0.1 router config, but the amount of issues this would cause with different hardware with fixed IPs is questionable. Any ideas why the apple products would have issues? Thanks...

Answer Wiki:
It should not matter what the gateway address is as long as the devices are in the same subnet. IP should be IP. Make sure the subnet mask matches on the Mac's and the gateway. Do the Mac's have some kind of firewall blocking this access? Is there an edge firewall restricting access by certain devices? Did this access work at all while the previous admin was there? Have you put a sniffer (<a href="http://www.wireshark.org">Wireshark</a>) on the wire to see what is happening with the traffic? One more thing - can you reach any of the Apple devices from a nearby (network-wise) PC by ping? Follow up with the sniffer (wireshark) as Labnuke suggests - a sniffer IS YOUR FRIEND!. BobKberg

there is nothing restricting the devices, and that is one of the weird issues. I can ping them, the ip address is correct, the subnet is correct, but they cannot get “out”. Everything intra is fine, but outside the router they are lost.

What version of MacOS are you using? Are you running Spanning Tree Protocol? Older MacOS versions had issues with it, described here:

http://docs.info.apple.com/article.html?artnum=30922

and I see no update which indicates that they have been satisfactorily resolved (but I could very definitely be incorrect about that).

Switch to PCs.

Sorry. I had to say it.

Try entering this 64.233.187.99 into the URL of your browser, if Google comes up, check your DNS settings. If Google does not come up then I’d suspect your gateway settings, though your DNS might be incorrect as well. You won’t know if DNS is working on the internet until your gateway is set up correctly. Usually the gateway address setting is the same as your router’s IP address. For DNS try something like 206.141.193.55 or any of the many on this list but you have to have a functioning gateway before DNS will do you any good!
Good Luck!

It is not the MacOS. The iPhones and Mac powerbooks work great with other wifi networks – and all other PC devices were great on this wifi network.

I hate Macs… I just want the damn iPhones to work on wifi.

The iPhones and Mac powerbooks all grab the correct IPs, subnets, and gateway addresses. They also grab the correct DNS settings. I can have it done through DHCP or manually, and I get the same result. The only thing I can point to is the router not being at X.X.X.1…

This is the weirdest problem I have every seen.
