Router only works with some IP numbers...

[Guest]

Archived from groups: alt.internet.wireless (More info?)

Hello All!

I have a wireless router (NETGEAR 814v2) working with a cable connection
(DHCP server), serving two Macintosh computers (system 9.0 one, and 10.3 the
other), since the beginning I found the router connection erratic, sometimes
working and sometimes not, with frequent cuts. After some investigations I
discovered that the router only connects when the IP is within a certain
range, close to the router address (192.168.x.x); when the IP is other
number, like 169.254.32.xxx or 217.70.66.xx the router can't connect or cuts
connection when IP changes to a number different from 192.xxx.x.x
My problem is that I have a dynamic IP (fixed IP is too expensive for a home
user) and my ISP changes IP too often (5 times a day or even much more).
There is still some hope for my wireless Internet? I send thanks in advance
to anyone who can give me any idea, since I am lost, being nothing like an
electronics expert, and just to explore the cause of my problem I had to
spend hours and hoursŠ

Thanks for your attention to this message.

I think you are confusing cause and effect. The 192.168.x.x and
169.254.x.x addresses are local only, not addresses that your router
uses to communicate with the Internet. Assuming that your Mac is set to
use DHCP on its AirPort connection, having an addresses in the
169.154.x.x range indicates that it was unable to get an IP address from
the Netgear router's DHCP server and has assigned an IP address to
itself. 217.70.66.x is a public address belonging to your ISP in
Portugal. It should not be in use on the LAN (local) side of the router,
where addresses should be within the router's subnet (address range).

If you know the router's IP address (probably 192.168.0.1), you can try
assigning IP addresses to your Macs manually (such as 192.168.0.2 with a
"Subnet Mask" of 255.255.255.0 and 192.168.0.1 entered in the "Router"
and "DNS Servers" boxes). But I suspect that the problem will recur, as
it sounds like a defect or configuration problem in the router. Perhaps
the router's DHCP server is not working correctly?

Many thanks for your answer.
I think I have the problem solved now, anyway I will print your answer to do
what you suggest if problem occur again. In fact I think my problems were
due to the fact that I used to boot modem and router at the same time,
because they are plugged both on electricity. A friend over the internet
told me to boot the modem and just after modem is working and stable, then
plug the router to the electricity and only after that boot computer. Since
I am using this method I can connect correctly at first attempt.
Meanwhile I had to solve another problem, this hardware related, that could
be also related to the erratic connection I had. At some point the computer
that receives the net by wireless antenna (eMac with system 10.3) stopped to
recognize the Airport Extreme card. I opened the access to the Airport and
it was not firmly inserted (fast work done by a technician). I just inserted
it firmly and computer recognized it again. So at this point things are
working fine.

Many thanks for your answer and Greetings from Portugal.

Many routers will allow you to change the IP address, however, the
169.254.... address, though it is a private one, usually means a
misconfiguration. As for the 217.70.xxx, I'm not familiar with it. In
reference to having a fixed IP, you could manually configure your
computers to use the same IP address within the DHCP listing. You would
basically be giving each computer a fixed IP despite the changes made to
your dynamic IP address by your ISP.
