We have cox as an internet provider; last night we were unable to send mail thru apple mail it was giving a message that the server was not available; however we had internet access. I called Cox to trouble shoot we unplugged everything and then reboted the apple router and the cox modem. The modem is working because once connected directly to my lap top we have internet access and are able to send and receive mail. The apple extreme router never came back up we have a constant amber bliking light I have tried numerous times to reset the router without success. Any ideas?

Dear calbearsgo,

Can you make sure your 8-port Netgear switch have no IP or has DHCP Server.
Or did you try to connect your Apple Extreme Base to the Netgear switch using Cross Cable?

Try doing a Trace Route on DOS ;

Open DOS - Start > click Run > type "cmd" = DOS

DOS COMMAND

tracert www.yahoo.com

IF THE RESULT WILL SHOW A " * " or timeouts then it is something to do with your line or if the response time is very high like 100ms 200ms 300ms then it is something to do with the line indeed ( normal = 1 ms - 50ms)

SOURCE: apple extreme router will not find the new ip

Turn the cable-modem off.
Turn the router off.
Turn your computer off.
Turn the cable-modem on, and wait until its lights settle-down to the usual "pattern".
Turn the router on, and similarly wait.
Turn your computer on, and similarly wait.
You should now have Internet access.

It's a common problem with wireless routers, especially with certain ISP's, there's several theories about why this happens including cheap parts and software on the routers but it can be much worse if it's over a cable connection. Possibly because the MTU is higher on cable networks than wireless ones. This issue doesn't seem to affect wired connections to the routers as much. ie you may still get a working wired connection even if the wireless isn't working.

Certain makes are known to behave this way, with certain ISP's. eg in england there's a cable company called virgin media, belkin routers really don't seem to like them, but netgear seem to work much better, which is probably why virgin recommend netgear and will only supply netgear routers themselves.

Try changing the channel id if it's wireless, as there may be a lot of interference around you and this may or may not have a bearing on this issue. If that doesn't help then ask your isp what make they recommend as they should have an idea of what will work best, at least the tech support dept should.

In my opinion the best makes of routers are netgear and linksys. I also like belkin although they aren't as good as they used to be, and as mentioned can suffer from this problem quite badly in some cases. As you are with a cable

You will never completely eradicate this problem, all wireless routers will need resetting now and again, but it should be weeks or preferably months between each time. Cisco routers may be more reliable but they're business routers and are very expensive, and probably a bit more complicated to setup.

ps. I used to work for virgin media as tech support.
