if you ping your routers do you get any replies??

 

by: YohanShmingePosted on 2004-03-16 at 12:44:30ID: 10609847

Is your computer located in the same physical place as it was yesterday?  Does it "see" the network, i.e. does it to connect to your wireless router?  What configuration are you using? DHCP? Are you using the software that came with your wireless NIC to connect, or are you using microsoft? What OS?  Sorry for all the questions, but their answers might be helpful.

 

by: mdean2000Posted on 2004-03-16 at 12:56:25ID: 10609976

thanks for the replys,

Computer is located in the same physical place, it does see the network but i can't access the other computers on the network. It gives an error message saying access denied, using DHCP, running windows 2003.....unable to ping ( I am not sure if i am pinging right!)

thanks

-Dean

Ok, so you're connected fine...

Go to the command prompt and type "ipconfig /all" then post the results here.

As for ping, I'm assuming your router is either 192.168.0.1 or 192.168.1.1 (prolly the last one).  just type "ping 192.168.1.1" and see what happens.

 

by: mdean2000Posted on 2004-03-16 at 13:17:49ID: 10610175

Alright ,

this is what I get when i type ipconfig/ all :

Windows Ip configuration
host name: dean-laptop
primary Dns suffix: jobhive.com (i don't know why)
Node Type: unknown
Ip routing enabled : no
WINS proxy enabled : no
DNS suffix search list: jobhive.com

physical address: bunch of numbers
DHCP enabled: yes
autoconfiguration enabled: yes
autoconfiguration ip address: bunch of numbers
subnet mask: bunch of numbers

ping is not working

thanks

Hmm, the "bunch of numbers" could be important.  To copy exactly what you see in DOS, you can right-click and hit Select All, that way you dont have to type it out :-D
You say you don't know why "jobhive.com" is there?  Is that your ISP or something?  Perhaps you've stumbled onto some other wireless network in the area?

 

by: maxncaPosted on 2004-03-16 at 13:35:57ID: 10610360

can power cycle the router and check the dns settings, because it seemd tobe you are not connected to the network at all, you can still see the network because the network records still saved into your compter since the last connection you did to the network.

 

by: YohanShmingePosted on 2004-03-16 at 13:42:22ID: 10610421

Try "ipconfig /release" then "ipconfig /renew" from the command prompt.

 

by: mdean2000Posted on 2004-03-16 at 13:53:10ID: 10610527

Thanks to all of you,

what worked is powering off the router for few minutes, turn it back on and everything seemed to be working fine. I wonder why that happened though, is it something will happen so often, wireless network still confuse me, is it secure or how to make it secure....if anyone knows please tell me

 

by: maxncaPosted on 2004-03-16 at 14:11:36ID: 10610701

sometimes this happen and the software inside the router frezz up, so you only need to restart the router to refresh the software inside it.
for your question regarding how is the wireless network secure, I can tell you there is nothing secure in any network connected directly to the internet.

 

by: YohanShmingePosted on 2004-03-16 at 14:16:15ID: 10610737

This is true, but there are some basic security measures you can take.  If you're using wireless G, then you can enabled WEP.  You can also restrict who can access your network by MAC address...but thats a whole 'nother question ;-)
