Hi
Is this a new system which has never worked ?
or a system which has stopped working ?
Normally you connect devices in following order
Broadband or cable modem -- router /wireless access point -- (switch optional) -- your PC
If router /wireless access point has built in switch or not you can add extra switches if necessary
You need to loginto router (wireless access point) via a network cable
Via any internet browser
Router I/p address will be something like 192.168.1.1
See documentation
See if wireless is enabled
, what is SSID setting?
(often preset to make of router or name of ISP)
What security setting and password for wireless connection?
Once you have these details and wireless turned on you can try to connect by wireless
If it suddenly stopped working power cycling router (wireless access point) often works
Regards
