hi guys, my problem is ihave just bought a netgear wireless adsl router which i only use as a router as i am on cable broadband,
the main pc is hard linked to the router and our laptop has wireless adapter.
the internet works on both but am unable to get a network.
i cant seem to talk to the router with main pc, tried to ping it but comes up with gobbledegook. however i can talk to it with laptop
any suggestions,
Brendan
 
Thats odd. Have you tried entering in the default IP for the router and accessing the administrative control panel?
 
So let me see if i understand correctly

you have a pc and a notebook
the pc has a cat5 cable to the router
the notebook is wireless

what are the OS's I will assume XP IF xp are they home or professional ?

you want to create a network ?

do you have anyfirewalls on,,, even the windows firewall ? turn them off

click start then run
type ncpa.cpl
then click ok or press enter
highlight your NIC
click advanced
then network ident

your workgroup name needs to be the same on the desktop and the lap top

you need to use peer to peer networking, so the notebook log on account has to be also on the desktop and the desktop account has to be on the notebook. So if you log on with " Fred " on the notebook, you have to create "fred" on the desktop.

you have to share a folder on each machine, if you have home, you only have simple file sharing. If you have prof turn off simple file sharing in folder ops \ view
 
i have now got to the point where i can ping from my wireless laptop to my pc but not other way around, and neither will ping the router.
yes im running xp.
also everytime i turn off the laptop i lose internet when i turn it back on, to get internet i have to reboot router.
hope this is clear
 
ics = internet connection sharing . It is for one machine is connected to the internet and other machines connect to the internet through that machine. As in a dial up account for one pc that is shared over a peer to peer cat5 network.
the exceptions are for the firewall,
do you have home of professional version ?

type ncpa.cpl into the run box on the start menu and click enter or ok
this should take you to your Network connections, do you see a little lock at the top of the network icon ?

also in the run box type in cmd , click enter
then type ipconfig/all
then hit enter
what does it say for your default ip address and gateway ?
 
Hmmm something is wrong. If you are connected to the router you should have an ip address like 192.168.xxx.xxx or something else in the private ip range.

so you have the coax cable going to the broadband modem, then a cat5 cable to the correct port on the router ( should say internet or something like that ) then a cat5 cable from the router to your pc ?

if you turn of the modem for a minute turn it back on , wait a minute then do the ipconfig again does the ip address change ?

if it does you are deffinately not connected right or the router is in bridge mode, if it has that state,,,, check all your wiring and your manual, i think you have the cable from the modem in the wrong port on the router. I think you have it in the ports that are the hub or switch.
 
there is no port to plug in my ehernet cable from the cable modem to the router just 4 hubs, i have just chosen one of those hubs and one hub to my pc, perhaps that is the problem.
the only other connection is a port for the adsl rj45 cable which i am no using

what do you think
 
adsl rj45 cable which i am no using

..that is where you need to plug 'er in

it will never work if you just plug it in to one of the hub ports AND that is why you have to turn the router off/on to get the other one to work. The ip address from your isp is used by either the notebook or the desktop. If you use a broadband router, correctly, NAT comes into play and that one isp ip address is shared with up to 256 PC's. Also your PC / notebook are not protected from the internet. Most modern BB Routers have SPI which is like a firewall and in fact you may also have a firewall in the router also.
