Equipment connected to Asus Chromebox (PC):
2wire 3800 HGV-B Residential Gateway
Netgear N300 Wireless N Router (WNR2000v2)
Cisco VEN401 Wireless Access Point

Laptop:
Dell Inspiron 5100
Windows XP
Netgear WG511 wireless PC card (Wireless b/g protocol)

Configuration:
Netgear N300 connected behind 2wire RG
Cisco WAP connected into Netgear N300

Devices connected to wireless network:
XBox360 (Wireless adapter for xbox live, Not always connected, use it as needed)
Chromebox (PC, Not always connected, use it as needed)
LG smart TV
2 AT&T Uverse wireless receivers
Samsung Galaxy S2 (Not always connected, use it as needed)
Epson XP-410 Wireless Printer

Problem:
Laptop cannot even find the wireless network in question. All other devices can find and connect to said network.

I have set the router to 145MB (Or is it MBPS, don't remember) which is broadcasting in b/g/n and my laptop's wireless PC card supports b/g protocols. Not sure what is going on.

Also, I have not hidden the router's SSID so other devices can connect to it.
 
Restart the router and wait until it's synced and no error lights.
Now restart Windows on the problem laptop.
Check available networks again.

Note: you may get away with just restarting the laptop, but for completeness I've included router restart also.
That's what I do whenever my wife's laptop loses the network, I restart them both. Works every time for me.

Tried the above, still a no go. If only I knew someone with another wireless card, so I can try to rule out the wireless PC card as the problem.

Could it be possible the wireless PC card in the laptop may not be compatible with my N300 wireless router?

Oh forgot to mention 2 things, I am running XP with SP3 installed if it makes a difference and the internet works fine on the laptop when you connect it via an ethernet cable.

Ok I got it all figured out.

I had to enable the wireless connection/security back on the residential gateway. Went to my laptop and it found the wireless network and managed to connect to it.

My laptop will connect to the network above and all other devices will connect to the wireless n router which is connected via the RG.

For some reason or another, my laptop PC wireless adapter will not detect the N300 router and not sure why.
