I put a new router in place that has wireless.

When i log on using hte Lan I can get outside the gateway to the
internet ( i am there now ).

When i log on using the wireless, i get an ip, but I cant get out?

I am at a loss why. Is my firewall preventing me from getting out or
something?

Anything I should check?

Mike

Debug this a little. You get an IP, but can you ping the access point
or any other system on the network? Is the address an RFC1918 private
address (192.168.x.x, 172.16.x.x, or 10.x.x.x)? Do you get the same
address when wired and wireless? Is the wired port a hub port on the
router?

Do an IPCONFIG/all Do you have entries for the default router and dns
server?

Can you open the router administration page in a web browser? If so,
turn on logging and watch the logs while you try to access the Internet.

Good luck,

dMn

Do you have a DHCP server or are you getting a 169.X>X>X IP (Automatic
Private IP Addressing)? There are quite a few things that can be
wrong, Do a little trouble shooting and get back to us.

We have several Wireless Routers on premise. I control both the LAN,
the WAN and the Wireless. Here is what to check.
1. Check if you can ping 127.0.0.1 (Loopback - Verifies IP STACK)
2. run an IPCONFIG /all (IFCONFIG on a MAC/LINUX)
3. PING the ROUTER ADDRESS (default gateway)
4. PING the DNS SERVERS
5. A lot of times, you will have a route, but not a proper DNS (Domain
Name Service - Domain Names (i.e. yahoo.com) to IP Address)
6. Try pinging the following:
yahoo.com - ping 216.109.112.135
google.com - ping 72.14.207.99

if you can ping those, then your gateway is working and you are having
(most likely) a DNS issue. You may have to use you providers DNS entry.
Almost all routers, if you get into their management software (WEB
BASED), will show you the actual IP and DNS entries the router uses.
Most of the time, especially on wireless, your router will give itself
as the DNS server. You may have to add your providers DNS entries to
your own IP (Network) stack.
Here is an almost universal DNS server (204.117.214.10). It is the
sprintlink DNS server (ns1.sprintlink.net). I used to manage a T1 line,
and used it, for DNS. Many large ISP's use Sprint as their backbone.

Good Luck,
TCD
