That's really strange.
Your laptop can pickup other wireless routers, but not this one.
Other laptops can pickup other wireless routers and this one.
That's clearly something between this laptop and this router. Totally out of the reach of your network provider (his responsibility ends where the signal enters your house, or - if he provided the modem at the modem). Only when he also provided the router, he MAY be involved. But the router is working fine, or other laptops wouldn't find it. So I can imagine he can't help.
Just an experiment: does changing the channel (1 through 14) and the encryption (none, WEP, WPA) help?
Computer Make: Dell Inspiron 1520
Network Card: 802.11g
Router: Netgear CG2001D
My laptop can pick up other wireless networks but will not pick mine, it won't even show. The other laptops in my house can pick up the wireless and connect with no problem. If I use an ethernet cable I can connect no problem but I want to know why I can't find my wireless.
I ran command script and these were my results. Any significance?
Physical Address Transport Name
GU-HO-FU-SY-HO-GO Media disconnected
HI-HO-GO-HO-HI-JO Media disconnected
(MAC Address FAKE!!!)
Also I accessed my router settings through the ethernet and found out I was not on the connected wireless devices. Again, is that of any significance? I managed to manually put in my MAC address but even after I press apply it shows only on the allowed access list and not on the connected wireless devices list where all the other laptops that are working fine are listed. Again is that of any significance. I tried phoning my network provider and all they say is the problem is my laptop when clearly their knowledge of the situation is too limited to generalise the problem and you can tell most times they are reading off a check-list; I'm also not willing to pay extravagant fees to any techs, I'm a broke student. Any help is greatly appreciated guys.
