no ip address when connected to router

Hello all,

I know this question has come up 1000 times before, but I am trying to connect my desktop wirelessly to a router, but can't grab an ip address.

-rebooted both the cable modem and router.

-tried entering all info statically

-Both firewall and norton shutdown when trying to configure

I am running my laptop next to the PC and am grabbing an ip address no problem from the same router...any suggestions? Driving me crazy! Thanks in advance.

There is a very good chance the wireless adapter is faulty.
Call the Tech Support Department and arrange an RMA.

Since you tried static IPs, and failed, it is clear there are no DHCP issues.

Your adapter is a bad one. You might try the store you bought it from to see if they will accept a D.O.A. and let you pickup a new adapter.

If this is an older adapter, and a PCMCIA adapter used in a notebook, the RMA possibility is gone. Purchase a new adapter. In my experience, notebook adapters other than mini-PCI adapters built-in to the notebook itself are lucky to last three years if you are careful with them.

 

so I switched out the wireless card...

still no dice. will connect to the router just fine, but can't grab an ip! any other suggestions guys?

Cannot grab ip ?

Lots of reasons with wireless that you cannot grab an ip.
You have not specified your OS or your familiarity or lack of familiarity with wireless.
I assume that the router is grabbing an internet signal .
However your wireless computer is not.
First check what the wireless settings are in the router.
For starters turn off the encryption. You may even want to reset the router back to factory defaults.
Check to see what the network name (ssid) is in the router.
Then see if your wireless card utlilty finds it when it scans.
You have to connect to that signal basically.
Your settings in your windows utility may be set for security not to grab anything ( something like connect to unsecured networks may be checked off).
If you are able to connect that way good.

You can use a networking utlilty program called Network Magic if you wish.
Simplifies the networking. After 30 days it reverts to the basic free version which should more than meet your needs.

Things to check for if you cannot.
Is the router broadcasting properly i.e is the transmission set to allow your card to receive. You may have an older but fine b card and the router is set to transmit on g only. There will be a setting to transmit on both.
The biggest problem is interference from neigbouring routers.
Change the channel from channel 6 to whatever. Channels 1 and 11 ( at either end of the range are the 2 next choices).
The signal of a neighboring router does not have to be close or even detectable to interfere with your reception.
Just change the channel.
If you can set up and receive internet you can now set up the encryption in the router.
There are diffirent formats. WEP 64 bit, WEP 128 bit and WPA.
WEP 64 bit is the easiest to start of.
You either create a code or generate a code from a passphrase in the router.
The signal is now encrypted.
In order for you to log on you
1) try to connect to the router as before
2) on trying to connect you will be asked for code. Enter the code you generated and applied in the router.
Thats it.

Forgive me if I have overexplained but you did not explain the specific problem or your level of expertise with wireless.

 

Where is the Gateway?

While most routers will act as a DNS proxy (decidedly not all), you have to specify a Gateay address when setting static IPs.

If you are trying to "piggyback' you likely are seeing a secured router. You can "connect" but you cannot do anything else.

 

Is your problem of no ip solved ?

I cannot ascertain if your problem of no ip is solved.
It is fairly simple - for some reason the router is not handing over an ip.
Is your handshake ok - i.e is the web encryption set identically between the two ?
Have you been able to connect any other wireless computers in your network ?
Have you tried turning off encryption in the router and card to see if grabs an ip?
I assume that you are close to the router. Have you tried changing the channel and even ssid ?
For some reason the router is not able to hand an ip to the adapter .
Check in your local area network list in the router to see if the wireless card was ever handed an ip. You can correlate the mac address printed on the card if it is removable to the mac address listed in the lan area of the router.
