 My routers lock up and need to be rebooted once in a blue moon.  If
yours do it frequently, replace them.

 I thought Ayesha had perished at the end of She.  I did not know she
lived on to complain about something as trivial as video streaming.

 Some routers do a better job than others.  For cheap devices, a Linksys
WRT54G, version 4 or less, reflashed to OpenWRT or DDWRT is about as
good as it gets.   I have a friend who used to really push a FIOS
connection regularly.  We had to go with a fancier router(about $200) to
keep the router from being the bottleneck.  So, I know the router makes
a difference.  If your cable modem is 6 MBPS or slower, a good home
router should be enough.

 The best setup is to get a router that is separate from the access
point.  The access point plugs into one of the ports on the router and
provides your your wireless connectivity.  I say this is best, but how
you use the network really affects how much difference you will notice.
I do mostly wired ethernet at home.  I typically have a dozen computers
running and connecting to the internet doing various things.  My access
point is not stressed because only wireless traffic needs to be routed
by it.  I use a couple of different wireless N routers, each flashed to
OpenWRT for performance,d security and features.  If you are doing
mostly wireless, then separating probably would not help you as much.
It sounds like you may have just one wired computer and I don't know how
busy it is relative to your total network.

As others have said WEP-256 does not exist.  ANy WEP is insecure because
the protocol is fundamentally broken.  WEP is somewhat easier on the
router computationally, but I always recommend WPA if you are going to
secure the access point.

 Wireless N can make a huge difference for streaming video.  Of course,
you need to have a wireless N setup on the router and the home
entertainment system.  It is not so much the speed of Wireless N as its
ability to sustain throughput in the face of other traffic.  If you have
other devices at home also using wireless G networking while you are
streaming video, then it is easy for home entertainment system to not
keep enough sustained bandwidth for video to stay perfect.  The more
devices on your network you move to N, the better, but probably updating
the home entertainment system and the access point is enough.

Good luck,
Ralph
