Wireless Networking

[ITheadache]

I am using windows server 2003, and am trying to set up Netgear wg102 access points. I am using WEP encryption, and and having problems with some of the set up. I currently have the access point configured (I believe correctly), but when I go wireless it can't access the internet. If I enable wireless while I am plugged in, it will give me a proper IP address, but when I disable the LAN, the wireless will say it is connected, but will not be able to connect to the internet, nor is it able to ping the server. Any ideas would be great.

Is the access point using DHCP? Is it giving the wireless cards the same network id and subnet as the physical server?

Post configuration and address information for analysis.

Hope this Helps.

DHCP client is enabled.

The access point has an IP address of

192.168.130.25

The servers DNS is 192.168.130.10
subnet is 255.255.255.0

and the computer is being assigned 192.168.130.113
subnet mask is 255.255.255.0
default gateway is 192.168.130.10

Th gateway of the AP must be set to that of the server, adn the gateway of the wireless card on the client machines needs to be the address of the AP.

Hope this Helps.

AP
IP Address
DHCP Client Enable
IP Address 192.168.130.25
IP Subnet Mask 255.255.255.0
Default Gateway 192.168.130.10
DNS Server 192.168.130.10

Server
IP Address 192.168.130.10
IP Subnet Mask 255.255.255.0
Default Gateway blank

Computer
IP Address 192.168.130.113
IP Subnet Mask 255.255.255.0
Default Gateway 192.168.130.10

This is what the client computer gets is The IP address is obtained automatically. I thought this was correct because we will be using 4 access points total, and they should work seemlessle as one network point.

Thanks

just humour me and set the gateway of the computer to the address of the AP(remember to do it in the wireless card config, and not the LAN) I always used to end up doing that making quick changed.

Hope this Helps.

I tried to change it, same thing happened where it gave it says that it is connected with good strength, but is unable to actually access the internet/network.

 

[ncotton]

Is the access point connected to a router? or straight to the server (if so, wireless or wired)? Does the server deffinately have access to the internet? Are you using active directory or is it just a normal box with 2003 server running, and no DC roles?
In your internet settings on the client machine, do you have any proxy/port forwarding set?

Hope this Helps.

The access point is connected to a switch (Netgear FSM7326P). The server is connected to the router, and then the switch is connected to the server. All hard wired computers and wireless AP's are then connected to our switch. The hard wired computers are properly connected to the internet. We are using the active directory to assign IP addresses, which are currently be assigned correctly.

Not sure on the proxy/port forwarding being set, how do I check that?

(Thanks for the help, I am not really a network guy, but ours is not working correctly, and I have been told to fix it.)

When I try and access the internet when wirelessly connected, the Lan light will blink, and the WAN light will blink, I think it has to be something to do with needing setting or apporoval from the server. I just don't know what they are.

 

[ncotton]

sounds more like an authentication issue between the machine and the wireless AP.

Hope this Helps.

Thats what I was thinking, but I am completely lost as to how to get the AP and server to interact properly.

hmmm...........weird, just a few days ago all the linksys AP in our building went on the fritz.......they are all wired to a switch, and the switch goes to our firewall which is also our DHCP server........the cards all say excelent strength, but they are not getting assigned an IP address, and can not access the internet or any other servers, i took the wireless net work apart, restored all AP back to factory default twice just for good measure, re-configured them all and stil nothing

the AP IP's are set statically, and the gateway is set to the firewall IP


interesting........

 

[johng75]

one thing i did see was that the AP is sending out packets successfully, which is probly why i get a signal from it, but all packings its attempting to recv are getting droped????

 

[ITheadache]

Sounds like a similar problem, except we have netgear access points

 

[nsantin]

Are you able to ping the server from the client over the wireless?

I have the same config using Linksys APs (not to be confused with routers, just APs) and have no issues. If you are using pure APs you need to set the the gateway as your server, not the AP.

 

[ncotton]

Have you tested without, by renewing the encryption keys? You have to pre-define your clients connection with the correct encryption key.

Hope this Helps.
