Wireless-G

I am new to wireless networking. I have the WRT300N router and WPC300N
notebook adapter. My cable modem is the Motorola SB5120. My ISP is
Comcast and I routinely connect at an astounding 270 Mbps. The servers
at Speedtest.net give me download speed results over 15Mbps. Nice.
However, two things got me stumped:

1. Sometimes I lose internet access even though my system tray monitor
shows that I still have an excellent connection. I end up having to
disconnect and reconnect in order for my browser to bring up web pages
again.

2. When I display wireless networks in my area I can connect to the
unsecured ones but still cant get my Firefox or IE browser to get bring
up a web page. The browser only seems to work with my own secured
wired/ wireless network.

This is obviously a Wireless-N question. Disregard the subject title.

Possibilities:
1. DHCP lease renewal problem
2. RF interference

Those networks may have protection against people like you.
