bad idea for 2 routers on the same class network!!!
u need divided to 2 difference subnet
router-1 192.168.1.x/16
router-2 192.168.1.y/8
or difference class of IP range
router-1 192.168.y.x/24
router-2 192.168.z.x/24
since ur client can live w/o the password
have u setup the MAC filtering on the router?? else someone will have a free WiFi.. LOL
back to the question
have u try difference wireless mode - N/G/B / N-only / G-only ??
is the router has WPS mode ??
enable the secondary SSID ??
when on WPA/WPA2, try switch between TKIP or AES, and WPA2 only or WPA only..
forget about WEP - easy to hack. better use non-password with MAC filtering.
some router allow u to change the Mhz in N mode, you can try other range, not only the channel #.
is the password have any funny character ?? always try [0-9][a-Z]
what OS on the laptop ??
try a Live linux CD and see u can connect to it. may be hardware compatibility issues with the chip ??
i always use it to test if somthing go wrong..
simple but always re-start the router and comp/laptop after the change, sometime it cached on the device and coz problem.
