jlewter,

Thanks again for your response. Sorry It has taken me so long to get back with you.
I think I understand what you said in your last post but I admit that this is the least understood aspect of my knowledge when it comes to diagnosing problems in a network setup issues.
I can see that my setup of the server and router may indeed be all wrong but when I read instruction on setting up the network in the SBS2003r2 and use of the CEICW wizard I am getting confused.
Instructions at this site: http://support.microsoft.com/kb/825763#top say this:
1. Select Use the following DNS server address. In the Preferred DNS server box, type the IP address of your server's local area connection. Leave the Alternate DNS server box blank.

Important Use the IP address from the server's local area connection for the preferred DNS server on the external network connection. Do not use DNS that is provided by your ISP or router, and do not click the Obtain DNS server address automatically option.

Here is a ipconfig /all result from the guest computer and according to it the settings are wrong when it points to the server for DNS instead of the router.

I am still confused as to how to set this up so I think I will have to seek out a local SBS2003 expert to help me get this set up correctly. Thanks you for posting for me and I think you have pointed out the problem correctly but I do not have the knowledge to make the proper corrections in SBS2003r2.
BTW I did send this info to Netgear support and as I thought they wanted me to force the firmware update again and hard reset the router and place all settings back in manually, which I did with the same results. The guest client connects to the secured or un-secured wireless guest network and shows internet access but when I try to open a page I get the DNS error page from explorer. If I enable the check mark to "allow local LAN access" then all works fine including internet access.
I will keep up with this thread until I find an answer or decide on some sort of work arround.
Thanks again1

Default Re: Guest wireless Shows connected but no internet

Hello!

I have the same problem as you have, only that i run fedora/amahi server with dhcp running..
I'm gonna try to disable the dhcp on the amahi server to check, and i can let you know how its going, but then the problem will be with the internal host domains for the amahi

Default Re: Guest wireless Shows connected but no internet

update!

disabled the dhcp on the amahi server who just had access to the main network, since guest network was not allowed to access main network, seems like that the my extra server(amahi with dhcp server running and disabled on netgear router) did not "see" the users on guest network, so they did not get a corrrect ip/submask.

enabled it on netgear router (dhcp) and disabled it on the server, restarted everything and it works fine! sad, because i wanted to run dhcp on the server

I think the problem here might be the DNS server..

The problem could be that DNS request cant pass back through the lan because it's blocked...

I will test this later this evening, but since it's sunday morning (5am US) I thought I would suggest it for you to try as your likely to be at church today and it'll save the long drive ..

Probably the best test (for proof) is done in a command prompt
type
"nslookup"
you will probably see something like
"Default Server: SBS-2003
Address: 192.168.1.10"

then just type something like "google.com"
and "if dns is getting blocked" you should see a few timeout request..

type "server 192.168.1.1"
it'll change to the router, then type "google.com"
and "hopefully" we'll get a valid IP result

If your able to get a result in the 2nt instance then manually setting dns server to 192.168.1.1 or 208.67.222.222 IN THE LATPOP would probably see it able to browse.

Is the 2003 server used to "filter" out things like porn and such?..
without knowing how involved the 2003 server is it's hard to suggest turning off things..

If you let the router control DHCP and DNS then it would all be zero config.

Just to add..
1) I am by no means a networking expert
2) I did suggest early on that the DNS server for "Guest" would likely need to be the router IP (or something internet based)...
3) I am by no means a networking expert

jlewter:
Thanks for the last response.
I did not get it in time to try out your suggestions as yet but I will.
I did find this interesting...development,

I set the wireless client on the guest network to use the DNS of 192.168.1.10, which is the SBS2003r2 server, and I get internet access. This setting is in the” wireless connection properties” IPv4 properties, “Use the following DNS server address”.
This works but I do not know why. Since the ipgonfig /all results in this guest computer when set to Get DNS automatically, shows that it is already set to and shows this same address of the server 192.168.1.10 for DNS server .
I hope this makes sense to someone as it sure does not make sense to me. Obviously I cannot ask guest network users to make this setting in order to connect to our guest network each time.
Now I am more confused than ever.
I will try your suggestions later this week.
Thanks!!!

Hi... What is the security set at on the router... WPA2? If so try changing to just WPA. I had similar problem,,, that fixed it as I tried all the same things as you, and in the end i just tried changing the security setting it for something to do... Great Success! The guest laptop may not be WPA2 compatible. Hope this helps.

Scud:
Security is set to:
WPA-PSK [TKIP] + WPA2-PSK [AES]
on all the wireless settings with the same passphrase. Each SSID has a different name so I can see what one I connect to. Chanel is set to auto.
I did this for simplicity for now as when I first tried testing and had the same problem I decided I would use a common setting and passphrase.
Help files in router shows this for WPA-PSK [TKIP] + WPA2-PSK [AES] " - Allow clients using either WPA-PSK [TKIP] or WPA2-PSK [AES]"
I also tried security setting of "none" on all wireless SSIDs and got the same results -DNS error.
The wireless client computer apparently has no problem with the security settings as it connects to the network in non guest SSID and in guest SSID but will DNS error for internet access in guestSSID only.

Default Re: Guest wireless Shows connected but no internet

Here is a reply from Netgear support on this problem. It seems to go along with what "jlewter" has been saying.
I need to study this some more to try to understand it and figure out how to apply this to my situatition with using a SBS2003r2 server and its capabilities and features affected by the router running DNS and DHCP.

From Agent ID: 3415
Case ID: 1331xxxx
Dear Mr. ....
My name is Angelo and I am following up on your support case.

After reviewing the information that you provided, I think I have a better understanding of your problem. It finally appeared to us that this is not a router problem. The guest network will only work properly if it is set to as your network's DHCP/DNS server (default). Since you are using a separate Internal DHCP server, I assume that you disabled the DHCP server feature of the router (when on router gui, it is found under LAN Setup under Advanced). Leaving this enabled while another DHCP server exists may cause conflicts and weird behaviours to happen on your network. As you know the guest network provides only Internet connection unless access to LAN is enabled. When your computer connects to the normal 2.4 or 5.0 wireless network, it gets Internet connection because request to the DNS server (SBS 2003r2) is allowed. However if a computer connects to the guest network, connection to the Internet will be denied since LAN access is disabled and the DNS server is located to LAN. You mentioned on your first letter that if LAN access is enabled then guest network will get Interenet access.

If there is no other DHCP/DNS server exist, the router will be in service giving its LAN port IP address as the default gateway and preferred DNS server of the computers connecting to it. The LAN IP of the router is always accessible even on a guest network without LAN access hence it can make guest wireless clients access the Internet through that IP. Again this is only possible if the router is the DHCP/DNS server. Forcing a guest client to use the DNS server IP by manual IP configuration may grant access to Internet but is very inconvenient (also this might have properly occured because the DHCP of the router is still enabled).

I hope that this response has enlightened you about the cause of the problem. I know that this has not solved the problem but we are just more than honest to tell you how the Guest System feature of the router works. Please feel free to contact us again if you have other questions.

Thank you for choosing Netgear. Have a great day!

Sincerely,

Angelo Luspo
